+
+ +The Google API Client Library enables you to work with Google APIs such as Gmail, Drive or YouTube on your server. + +These client libraries are officially supported by Google. However, the libraries are considered complete and are in maintenance mode. This means that we will address critical bugs and security issues but will not add any new features. + +**NOTE** The actively maintained (v2) version of this client requires PHP 5.6 or above. If you require support for PHP 5.2 or 5.3, use the v1 branch. + +## Google Cloud Platform + +For Google Cloud Platform APIs such as Datastore, Cloud Storage or Pub/Sub, we recommend using [GoogleCloudPlatform/google-cloud-php](https://github.com/googleapis/google-cloud-php) which is under active development. + +## Requirements ## +* [PHP 5.6.0 or higher](https://www.php.net/) + +## Developer Documentation ## + +The [docs folder](docs/) provides detailed guides for using this library. + +## Installation ## + +You can use **Composer** or simply **Download the Release** + +### Composer + +The preferred method is via [composer](https://getcomposer.org/). Follow the +[installation instructions](https://getcomposer.org/doc/00-intro.md) if you do not already have +composer installed. + +Once composer is installed, execute the following command in your project root to install this library: + +```sh +composer require google/apiclient:"^2.7" +``` + +Finally, be sure to include the autoloader: + +```php +require_once '/path/to/your-project/vendor/autoload.php'; +``` + +This library relies on `google/apiclient-services`. That library provides up-to-date API wrappers for a large number of Google APIs. In order that users may make use of the latest API clients, this library does not pin to a specific version of `google/apiclient-services`. **In order to prevent the accidental installation of API wrappers with breaking changes**, it is highly recommended that you pin to the [latest version](https://github.com/googleapis/google-api-php-client-services/releases) yourself prior to using this library in production. + +#### Cleaning up unused services + +There are over 200 Google API services. The chances are good that you will not +want them all. In order to avoid shipping these dependencies with your code, +you can run the `Google\Task\Composer::cleanup` task and specify the services +you want to keep in `composer.json`: + +```json +{ + "require": { + "google/apiclient": "^2.7" + }, + "scripts": { + "post-update-cmd": "Google\\Task\\Composer::cleanup" + }, + "extra": { + "google/apiclient-services": [ + "Drive", + "YouTube" + ] + } +} +``` + +This example will remove all services other than "Drive" and "YouTube" when +`composer update` or a fresh `composer install` is run. + +**IMPORTANT**: If you add any services back in `composer.json`, you will need to +remove the `vendor/google/apiclient-services` directory explicity for the +change you made to have effect: + +```sh +rm -r vendor/google/apiclient-services +composer update +``` + +**NOTE**: This command performs an exact match on the service name, so to keep +`YouTubeReporting` and `YouTubeAnalytics` as well, you'd need to add each of +them explicitly: + +```json +{ + "extra": { + "google/apiclient-services": [ + "Drive", + "YouTube", + "YouTubeAnalytics", + "YouTubeReporting" + ] + } +} +``` + +### Download the Release + +If you prefer not to use composer, you can download the package in its entirety. The [Releases](https://github.com/googleapis/google-api-php-client/releases) page lists all stable versions. Download any file +with the name `google-api-php-client-[RELEASE_NAME].zip` for a package including this library and its dependencies. + +Uncompress the zip file you download, and include the autoloader in your project: + +```php +require_once '/path/to/google-api-php-client/vendor/autoload.php'; +``` + +For additional installation and setup instructions, see [the documentation](docs/). + +## Examples ## +See the [`examples/`](examples) directory for examples of the key client features. You can +view them in your browser by running the php built-in web server. + +``` +$ php -S localhost:8000 -t examples/ +``` + +And then browsing to the host and port you specified +(in the above example, `http://localhost:8000`). + +### Basic Example ### + +```php +// include your composer dependencies +require_once 'vendor/autoload.php'; + +$client = new Google\Client(); +$client->setApplicationName("Client_Library_Examples"); +$client->setDeveloperKey("YOUR_APP_KEY"); + +$service = new Google_Service_Books($client); +$optParams = array( + 'filter' => 'free-ebooks', + 'q' => 'Henry David Thoreau' +); +$results = $service->volumes->listVolumes($optParams); + +foreach ($results->getItems() as $item) { + echo $item['volumeInfo']['title'], "
\n"; +} +``` + +### Authentication with OAuth ### + +> An example of this can be seen in [`examples/simple-file-upload.php`](examples/simple-file-upload.php). + +1. Follow the instructions to [Create Web Application Credentials](docs/oauth-web.md#create-authorization-credentials) +1. Download the JSON credentials +1. Set the path to these credentials using `Google\Client::setAuthConfig`: + + ```php + $client = new Google\Client(); + $client->setAuthConfig('/path/to/client_credentials.json'); + ``` + +1. Set the scopes required for the API you are going to call + + ```php + $client->addScope(Google_Service_Drive::DRIVE); + ``` + +1. Set your application's redirect URI + + ```php + // Your redirect URI can be any registered URI, but in this example + // we redirect back to this same page + $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']; + $client->setRedirectUri($redirect_uri); + ``` + +1. In the script handling the redirect URI, exchange the authorization code for an access token: + + ```php + if (isset($_GET['code'])) { + $token = $client->fetchAccessTokenWithAuthCode($_GET['code']); + } + ``` + +### Authentication with Service Accounts ### + +> An example of this can be seen in [`examples/service-account.php`](examples/service-account.php). + +Some APIs +(such as the [YouTube Data API](https://developers.google.com/youtube/v3/)) do +not support service accounts. Check with the specific API documentation if API +calls return unexpected 401 or 403 errors. + +1. Follow the instructions to [Create a Service Account](docs/oauth-server.md#creating-a-service-account) +1. Download the JSON credentials +1. Set the path to these credentials using the `GOOGLE_APPLICATION_CREDENTIALS` environment variable: + + ```php + putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json'); + ``` + +1. Tell the Google client to use your service account credentials to authenticate: + + ```php + $client = new Google\Client(); + $client->useApplicationDefaultCredentials(); + ``` + +1. Set the scopes required for the API you are going to call + + ```php + $client->addScope(Google_Service_Drive::DRIVE); + ``` + +1. If you have delegated domain-wide access to the service account and you want to impersonate a user account, specify the email address of the user account using the method setSubject: + + ```php + $client->setSubject($user_to_impersonate); + ``` + +### Making Requests ### + +The classes used to call the API in [google-api-php-client-services](https://github.com/googleapis/google-api-php-client-services) are autogenerated. They map directly to the JSON requests and responses found in the [APIs Explorer](https://developers.google.com/apis-explorer/#p/). + +A JSON request to the [Datastore API](https://developers.google.com/apis-explorer/#p/datastore/v1beta3/datastore.projects.runQuery) would look like this: + +```json +POST https://datastore.googleapis.com/v1beta3/projects/YOUR_PROJECT_ID:runQuery?key=YOUR_API_KEY + +{ + "query": { + "kind": [{ + "name": "Book" + }], + "order": [{ + "property": { + "name": "title" + }, + "direction": "descending" + }], + "limit": 10 + } +} +``` + +Using this library, the same call would look something like this: + +```php +// create the datastore service class +$datastore = new Google_Service_Datastore($client); + +// build the query - this maps directly to the JSON +$query = new Google_Service_Datastore_Query([ + 'kind' => [ + [ + 'name' => 'Book', + ], + ], + 'order' => [ + 'property' => [ + 'name' => 'title', + ], + 'direction' => 'descending', + ], + 'limit' => 10, +]); + +// build the request and response +$request = new Google_Service_Datastore_RunQueryRequest(['query' => $query]); +$response = $datastore->projects->runQuery('YOUR_DATASET_ID', $request); +``` + +However, as each property of the JSON API has a corresponding generated class, the above code could also be written like this: + +```php +// create the datastore service class +$datastore = new Google_Service_Datastore($client); + +// build the query +$request = new Google_Service_Datastore_RunQueryRequest(); +$query = new Google_Service_Datastore_Query(); +// - set the order +$order = new Google_Service_Datastore_PropertyOrder(); +$order->setDirection('descending'); +$property = new Google_Service_Datastore_PropertyReference(); +$property->setName('title'); +$order->setProperty($property); +$query->setOrder([$order]); +// - set the kinds +$kind = new Google_Service_Datastore_KindExpression(); +$kind->setName('Book'); +$query->setKinds([$kind]); +// - set the limit +$query->setLimit(10); + +// add the query to the request and make the request +$request->setQuery($query); +$response = $datastore->projects->runQuery('YOUR_DATASET_ID', $request); +``` + +The method used is a matter of preference, but *it will be very difficult to use this library without first understanding the JSON syntax for the API*, so it is recommended to look at the [APIs Explorer](https://developers.google.com/apis-explorer/#p/) before using any of the services here. + +### Making HTTP Requests Directly ### + +If Google Authentication is desired for external applications, or a Google API is not available yet in this library, HTTP requests can be made directly. + +If you are installing this client only to authenticate your own HTTP client requests, you should use [`google/auth`](https://github.com/googleapis/google-auth-library-php#call-the-apis) instead. + +The `authorize` method returns an authorized [Guzzle Client](http://docs.guzzlephp.org/), so any request made using the client will contain the corresponding authorization. + +```php +// create the Google client +$client = new Google\Client(); + +/** + * Set your method for authentication. Depending on the API, This could be + * directly with an access token, API key, or (recommended) using + * Application Default Credentials. + */ +$client->useApplicationDefaultCredentials(); +$client->addScope(Google_Service_Plus::PLUS_ME); + +// returns a Guzzle HTTP Client +$httpClient = $client->authorize(); + +// make an HTTP request +$response = $httpClient->get('https://www.googleapis.com/plus/v1/people/me'); +``` + +### Caching ### + +It is recommended to use another caching library to improve performance. This can be done by passing a [PSR-6](https://www.php-fig.org/psr/psr-6/) compatible library to the client: + +```php +use League\Flysystem\Adapter\Local; +use League\Flysystem\Filesystem; +use Cache\Adapter\Filesystem\FilesystemCachePool; + +$filesystemAdapter = new Local(__DIR__.'/'); +$filesystem = new Filesystem($filesystemAdapter); + +$cache = new FilesystemCachePool($filesystem); +$client->setCache($cache); +``` + +In this example we use [PHP Cache](http://www.php-cache.com/). Add this to your project with composer: + +``` +composer require cache/filesystem-adapter +``` + +### Updating Tokens ### + +When using [Refresh Tokens](https://developers.google.com/identity/protocols/OAuth2InstalledApp#offline) or [Service Account Credentials](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#overview), it may be useful to perform some action when a new access token is granted. To do this, pass a callable to the `setTokenCallback` method on the client: + +```php +$logger = new Monolog\Logger(); +$tokenCallback = function ($cacheKey, $accessToken) use ($logger) { + $logger->debug(sprintf('new access token received at cache key %s', $cacheKey)); +}; +$client->setTokenCallback($tokenCallback); +``` + +### Debugging Your HTTP Request using Charles ### + +It is often very useful to debug your API calls by viewing the raw HTTP request. This library supports the use of [Charles Web Proxy](https://www.charlesproxy.com/documentation/getting-started/). Download and run Charles, and then capture all HTTP traffic through Charles with the following code: + +```php +// FOR DEBUGGING ONLY +$httpClient = new GuzzleHttp\Client([ + 'proxy' => 'localhost:8888', // by default, Charles runs on localhost port 8888 + 'verify' => false, // otherwise HTTPS requests will fail. +]); + +$client = new Google\Client(); +$client->setHttpClient($httpClient); +``` + +Now all calls made by this library will appear in the Charles UI. + +One additional step is required in Charles to view SSL requests. Go to **Charles > Proxy > SSL Proxying Settings** and add the domain you'd like captured. In the case of the Google APIs, this is usually `*.googleapis.com`. + +### Controlling HTTP Client Configuration Directly + +Google API Client uses [Guzzle](http://docs.guzzlephp.org/) as its default HTTP client. That means that you can control your HTTP requests in the same manner you would for any application using Guzzle. + +Let's say, for instance, we wished to apply a referrer to each request. + +```php +use GuzzleHttp\Client; + +$httpClient = new Client([ + 'headers' => [ + 'referer' => 'mysite.com' + ] +]); + +$client = new Google\Client(); +$client->setHttpClient($httpClient); +``` + +Other Guzzle features such as [Handlers and Middleware](http://docs.guzzlephp.org/en/stable/handlers-and-middleware.html) offer even more control. + +### Service Specific Examples ### + +YouTube: https://github.com/youtube/api-samples/tree/master/php + +## How Do I Contribute? ## + +Please see the [contributing](.github/CONTRIBUTING.md) page for more information. In particular, we love pull requests - but please make sure to sign the contributor license agreement. + +## Frequently Asked Questions ## + +### What do I do if something isn't working? ### + +For support with the library the best place to ask is via the google-api-php-client tag on StackOverflow: https://stackoverflow.com/questions/tagged/google-api-php-client + +If there is a specific bug with the library, please [file an issue](https://github.com/googleapis/google-api-php-client/issues) in the GitHub issues tracker, including an example of the failing code and any specific errors retrieved. Feature requests can also be filed, as long as they are core library requests, and not-API specific: for those, refer to the documentation for the individual APIs for the best place to file requests. Please try to provide a clear statement of the problem that the feature would address. + +### I want an example of X! ### + +If X is a feature of the library, file away! If X is an example of using a specific service, the best place to go is to the teams for those specific APIs - our preference is to link to their examples rather than add them to the library, as they can then pin to specific versions of the library. If you have any examples for other APIs, let us know and we will happily add a link to the README above! + +### Why does Google_..._Service have weird names? ### + +The _Service classes are generally automatically generated from the API discovery documents: https://developers.google.com/discovery/. Sometimes new features are added to APIs with unusual names, which can cause some unexpected or non-standard style naming in the PHP classes. + +### How do I deal with non-JSON response types? ### + +Some services return XML or similar by default, rather than JSON, which is what the library supports. You can request a JSON response by adding an 'alt' argument to optional params that is normally the last argument to a method call: + +``` +$opt_params = array( + 'alt' => "json" +); +``` + +### How do I set a field to null? ### + +The library strips out nulls from the objects sent to the Google APIs as its the default value of all of the uninitialized properties. To work around this, set the field you want to null to `Google\Model::NULL_VALUE`. This is a placeholder that will be replaced with a true null when sent over the wire. + +## Code Quality ## + +Run the PHPUnit tests with PHPUnit. You can configure an API key and token in BaseTest.php to run all calls, but this will require some setup on the Google Developer Console. + + phpunit tests/ + +### Coding Style + +To check for coding style violations, run + +``` +vendor/bin/phpcs src --standard=style/ruleset.xml -np +``` + +To automatically fix (fixable) coding style violations, run + +``` +vendor/bin/phpcbf src --standard=style/ruleset.xml +``` diff --git a/vendor/google/apiclient/composer.json b/vendor/google/apiclient/composer.json new file mode 100644 index 00000000..c29adc2c --- /dev/null +++ b/vendor/google/apiclient/composer.json @@ -0,0 +1,47 @@ +{ + "name": "google/apiclient", + "type": "library", + "description": "Client library for Google APIs", + "keywords": ["google"], + "homepage": "http://developers.google.com/api-client-library/php", + "license": "Apache-2.0", + "require": { + "php": "^5.6|^7.0|^8.0", + "google/auth": "^1.10", + "google/apiclient-services": "~0.13", + "firebase/php-jwt": "~2.0||~3.0||~4.0||~5.0", + "monolog/monolog": "^1.17|^2.0", + "phpseclib/phpseclib": "~2.0||^3.0.2", + "guzzlehttp/guzzle": "~5.3.3||~6.0||~7.0", + "guzzlehttp/psr7": "^1.2" + }, + "require-dev": { + "phpunit/phpunit": "^5.7||^8.5.13", + "squizlabs/php_codesniffer": "~2.3", + "symfony/dom-crawler": "~2.1", + "symfony/css-selector": "~2.1", + "cache/filesystem-adapter": "^0.3.2|^1.1", + "phpcompatibility/php-compatibility": "^9.2", + "dealerdirect/phpcodesniffer-composer-installer": "^0.7", + "composer/composer": "^1.10" + }, + "suggest": { + "cache/filesystem-adapter": "For caching certs and tokens (using Google\\Client::setCache)" + }, + "autoload": { + "psr-4": { + "Google\\": "src/" + }, + "files": [ + "src/aliases.php" + ], + "classmap": [ + "src/aliases.php" + ] + }, + "extra": { + "branch-alias": { + "dev-master": "2.x-dev" + } + } +} diff --git a/vendor/google/apiclient/src/AccessToken/Revoke.php b/vendor/google/apiclient/src/AccessToken/Revoke.php new file mode 100644 index 00000000..45b60548 --- /dev/null +++ b/vendor/google/apiclient/src/AccessToken/Revoke.php @@ -0,0 +1,81 @@ +http = $http; + } + + /** + * Revoke an OAuth2 access token or refresh token.

+ +## Description + +This is Google's officially supported PHP client library for using OAuth 2.0 +authorization and authentication with Google APIs. + +### Installing via Composer + +The recommended way to install the google auth library is through +[Composer](http://getcomposer.org). + +```bash +# Install Composer +curl -sS https://getcomposer.org/installer | php +``` + +Next, run the Composer command to install the latest stable version: + +```bash +composer.phar require google/auth +``` + +## Application Default Credentials + +This library provides an implementation of +[application default credentials][application default credentials] for PHP. + +The Application Default Credentials provide a simple way to get authorization +credentials for use in calling Google APIs. + +They are best suited for cases when the call needs to have the same identity +and authorization level for the application independent of the user. This is +the recommended approach to authorize calls to Cloud APIs, particularly when +you're building an application that uses Google Compute Engine. + +#### Download your Service Account Credentials JSON file + +To use `Application Default Credentials`, You first need to download a set of +JSON credentials for your project. Go to **APIs & Services** > **Credentials** in +the [Google Developers Console][developer console] and select +**Service account** from the **Add credentials** dropdown. + +> This file is your *only copy* of these credentials. It should never be +> committed with your source code, and should be stored securely. + +Once downloaded, store the path to this file in the +`GOOGLE_APPLICATION_CREDENTIALS` environment variable. + +```php +putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/my/credentials.json'); +``` + +> PHP's `putenv` function is just one way to set an environment variable. +> Consider using `.htaccess` or apache configuration files as well. + +#### Enable the API you want to use + +Before making your API call, you must be sure the API you're calling has been +enabled. Go to **APIs & Auth** > **APIs** in the +[Google Developers Console][developer console] and enable the APIs you'd like to +call. For the example below, you must enable the `Drive API`. + +#### Call the APIs + +As long as you update the environment variable below to point to *your* JSON +credentials file, the following code should output a list of your Drive files. + +```php +use Google\Auth\ApplicationDefaultCredentials; +use GuzzleHttp\Client; +use GuzzleHttp\HandlerStack; + +// specify the path to your application credentials +putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/my/credentials.json'); + +// define the scopes for your API call +$scopes = ['https://www.googleapis.com/auth/drive.readonly']; + +// create middleware +$middleware = ApplicationDefaultCredentials::getMiddleware($scopes); +$stack = HandlerStack::create(); +$stack->push($middleware); + +// create the HTTP client +$client = new Client([ + 'handler' => $stack, + 'base_uri' => 'https://www.googleapis.com', + 'auth' => 'google_auth' // authorize all requests +]); + +// make the request +$response = $client->get('drive/v2/files'); + +// show the result! +print_r((string) $response->getBody()); +``` + +##### Guzzle 5 Compatibility + +If you are using [Guzzle 5][Guzzle 5], replace the `create middleware` and +`create the HTTP Client` steps with the following: + +```php +// create the HTTP client +$client = new Client([ + 'base_url' => 'https://www.googleapis.com', + 'auth' => 'google_auth' // authorize all requests +]); + +// create subscriber +$subscriber = ApplicationDefaultCredentials::getSubscriber($scopes); +$client->getEmitter()->attach($subscriber); +``` + +#### Call using an ID Token +If your application is running behind Cloud Run, or using Cloud Identity-Aware +Proxy (IAP), you will need to fetch an ID token to access your application. For +this, use the static method `getIdTokenMiddleware` on +`ApplicationDefaultCredentials`. + +```php +use Google\Auth\ApplicationDefaultCredentials; +use GuzzleHttp\Client; +use GuzzleHttp\HandlerStack; + +// specify the path to your application credentials +putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/my/credentials.json'); + +// Provide the ID token audience. This can be a Client ID associated with an IAP application, +// Or the URL associated with a CloudRun App +// $targetAudience = 'IAP_CLIENT_ID.apps.googleusercontent.com'; +// $targetAudience = 'https://service-1234-uc.a.run.app'; +$targetAudience = 'YOUR_ID_TOKEN_AUDIENCE'; + +// create middleware +$middleware = ApplicationDefaultCredentials::getIdTokenMiddleware($targetAudience); +$stack = HandlerStack::create(); +$stack->push($middleware); + +// create the HTTP client +$client = new Client([ + 'handler' => $stack, + 'auth' => 'google_auth', + // Cloud Run, IAP, or custom resource URL + 'base_uri' => 'https://YOUR_PROTECTED_RESOURCE', +]); + +// make the request +$response = $client->get('/'); + +// show the result! +print_r((string) $response->getBody()); +``` + +For invoking Cloud Run services, your service account will need the +[`Cloud Run Invoker`](https://cloud.google.com/run/docs/authenticating/service-to-service) +IAM permission. + +For invoking Cloud Identity-Aware Proxy, you will need to pass the Client ID +used when you set up your protected resource as the target audience. See how to +[secure your IAP app with signed headers](https://cloud.google.com/iap/docs/signed-headers-howto). + +#### Call using a specific JSON key +If you want to use a specific JSON key instead of using `GOOGLE_APPLICATION_CREDENTIALS` environment variable, you can + do this: + +```php +use Google\Auth\CredentialsLoader; +use Google\Auth\Middleware\AuthTokenMiddleware; +use GuzzleHttp\Client; +use GuzzleHttp\HandlerStack; + +// Define the Google Application Credentials array +$jsonKey = ['key' => 'value']; + +// define the scopes for your API call +$scopes = ['https://www.googleapis.com/auth/drive.readonly']; + +// Load credentials +$creds = CredentialsLoader::makeCredentials($scopes, $jsonKey); + +// optional caching +// $creds = new FetchAuthTokenCache($creds, $cacheConfig, $cache); + +// create middleware +$middleware = new AuthTokenMiddleware($creds); +$stack = HandlerStack::create(); +$stack->push($middleware); + +// create the HTTP client +$client = new Client([ + 'handler' => $stack, + 'base_uri' => 'https://www.googleapis.com', + 'auth' => 'google_auth' // authorize all requests +]); + +// make the request +$response = $client->get('drive/v2/files'); + +// show the result! +print_r((string) $response->getBody()); + +``` + +#### Verifying JWTs + +If you are [using Google ID tokens to authenticate users][google-id-tokens], use +the `Google\Auth\AccessToken` class to verify the ID token: + +```php +use Google\Auth\AccessToken; + +$auth = new AccessToken(); +$auth->verify($idToken); +``` + +If your app is running behind [Google Identity-Aware Proxy][iap-id-tokens] +(IAP), you can verify the ID token coming from the IAP server by pointing to the +appropriate certificate URL for IAP. This is because IAP signs the ID +tokens with a different key than the Google Identity service: + +```php +use Google\Auth\AccessToken; + +$auth = new AccessToken(); +$auth->verify($idToken, [ + 'certsLocation' => AccessToken::IAP_CERT_URL +]); +``` + +[google-id-tokens]: https://developers.google.com/identity/sign-in/web/backend-auth +[iap-id-tokens]: https://cloud.google.com/iap/docs/signed-headers-howto + +## License + +This library is licensed under Apache 2.0.

A Query object then encodes the value before sending over the wire. This +means that even value query string values (e.g., ":") are url encoded. This +makes the Query class match PHP's http_build_query function. However, if you +want to send requests over the wire using valid query string characters that do +not need to be encoded, then you can provide a string to Url::setQuery() and +pass true as the second argument to specify that the query string is a raw +string that should not be parsed or encoded (unless a call to getQuery() is +subsequently made, forcing the query-string to be converted into a Query +object). + +## 5.0.2 - 2014-10-30 + +* Added a trailing `\r\n` to multipart/form-data payloads. See + https://github.com/guzzle/guzzle/pull/871 +* Added a `GuzzleHttp\Pool::send()` convenience method to match the docs. +* Status codes are now returned as integers. See + https://github.com/guzzle/guzzle/issues/881 +* No longer overwriting an existing `application/x-www-form-urlencoded` header + when sending POST requests, allowing for customized headers. See + https://github.com/guzzle/guzzle/issues/877 +* Improved path URL serialization. + + * No longer double percent-encoding characters in the path or query string if + they are already encoded. + * Now properly encoding the supplied path to a URL object, instead of only + encoding ' ' and '?'. + * Note: This has been changed in 5.0.3 to now encode query string values by + default unless the `rawString` argument is provided when setting the query + string on a URL: Now allowing many more characters to be present in the + query string without being percent encoded. See https://tools.ietf.org/html/rfc3986#appendix-A + +## 5.0.1 - 2014-10-16 + +Bugfix release. + +* Fixed an issue where connection errors still returned response object in + error and end events event though the response is unusable. This has been + corrected so that a response is not returned in the `getResponse` method of + these events if the response did not complete. https://github.com/guzzle/guzzle/issues/867 +* Fixed an issue where transfer statistics were not being populated in the + RingBridge. https://github.com/guzzle/guzzle/issues/866 + +## 5.0.0 - 2014-10-12 + +Adding support for non-blocking responses and some minor API cleanup. + +### New Features + +* Added support for non-blocking responses based on `guzzlehttp/guzzle-ring`. +* Added a public API for creating a default HTTP adapter. +* Updated the redirect plugin to be non-blocking so that redirects are sent + concurrently. Other plugins like this can now be updated to be non-blocking. +* Added a "progress" event so that you can get upload and download progress + events. +* Added `GuzzleHttp\Pool` which implements FutureInterface and transfers + requests concurrently using a capped pool size as efficiently as possible. +* Added `hasListeners()` to EmitterInterface. +* Removed `GuzzleHttp\ClientInterface::sendAll` and marked + `GuzzleHttp\Client::sendAll` as deprecated (it's still there, just not the + recommended way). + +### Breaking changes + +The breaking changes in this release are relatively minor. The biggest thing to +look out for is that request and response objects no longer implement fluent +interfaces. + +* Removed the fluent interfaces (i.e., `return $this`) from requests, + responses, `GuzzleHttp\Collection`, `GuzzleHttp\Url`, + `GuzzleHttp\Query`, `GuzzleHttp\Post\PostBody`, and + `GuzzleHttp\Cookie\SetCookie`. This blog post provides a good outline of + why I did this: https://ocramius.github.io/blog/fluent-interfaces-are-evil/. + This also makes the Guzzle message interfaces compatible with the current + PSR-7 message proposal. +* Removed "functions.php", so that Guzzle is truly PSR-4 compliant. Except + for the HTTP request functions from function.php, these functions are now + implemented in `GuzzleHttp\Utils` using camelCase. `GuzzleHttp\json_decode` + moved to `GuzzleHttp\Utils::jsonDecode`. `GuzzleHttp\get_path` moved to + `GuzzleHttp\Utils::getPath`. `GuzzleHttp\set_path` moved to + `GuzzleHttp\Utils::setPath`. `GuzzleHttp\batch` should now be + `GuzzleHttp\Pool::batch`, which returns an `objectStorage`. Using functions.php + caused problems for many users: they aren't PSR-4 compliant, require an + explicit include, and needed an if-guard to ensure that the functions are not + declared multiple times. +* Rewrote adapter layer. + * Removing all classes from `GuzzleHttp\Adapter`, these are now + implemented as callables that are stored in `GuzzleHttp\Ring\Client`. + * Removed the concept of "parallel adapters". Sending requests serially or + concurrently is now handled using a single adapter. + * Moved `GuzzleHttp\Adapter\Transaction` to `GuzzleHttp\Transaction`. The + Transaction object now exposes the request, response, and client as public + properties. The getters and setters have been removed. +* Removed the "headers" event. This event was only useful for changing the + body a response once the headers of the response were known. You can implement + a similar behavior in a number of ways. One example might be to use a + FnStream that has access to the transaction being sent. For example, when the + first byte is written, you could check if the response headers match your + expectations, and if so, change the actual stream body that is being + written to. +* Removed the `asArray` parameter from + `GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header + value as an array, then use the newly added `getHeaderAsArray()` method of + `MessageInterface`. This change makes the Guzzle interfaces compatible with + the PSR-7 interfaces. +* `GuzzleHttp\Message\MessageFactory` no longer allows subclasses to add + custom request options using double-dispatch (this was an implementation + detail). Instead, you should now provide an associative array to the + constructor which is a mapping of the request option name mapping to a + function that applies the option value to a request. +* Removed the concept of "throwImmediately" from exceptions and error events. + This control mechanism was used to stop a transfer of concurrent requests + from completing. This can now be handled by throwing the exception or by + cancelling a pool of requests or each outstanding future request individually. +* Updated to "GuzzleHttp\Streams" 3.0. + * `GuzzleHttp\Stream\StreamInterface::getContents()` no longer accepts a + `maxLen` parameter. This update makes the Guzzle streams project + compatible with the current PSR-7 proposal. + * `GuzzleHttp\Stream\Stream::__construct`, + `GuzzleHttp\Stream\Stream::factory`, and + `GuzzleHttp\Stream\Utils::create` no longer accept a size in the second + argument. They now accept an associative array of options, including the + "size" key and "metadata" key which can be used to provide custom metadata. + +## 4.2.2 - 2014-09-08 + +* Fixed a memory leak in the CurlAdapter when reusing cURL handles. +* No longer using `request_fulluri` in stream adapter proxies. +* Relative redirects are now based on the last response, not the first response. + +## 4.2.1 - 2014-08-19 + +* Ensuring that the StreamAdapter does not always add a Content-Type header +* Adding automated github releases with a phar and zip + +## 4.2.0 - 2014-08-17 + +* Now merging in default options using a case-insensitive comparison. + Closes https://github.com/guzzle/guzzle/issues/767 +* Added the ability to automatically decode `Content-Encoding` response bodies + using the `decode_content` request option. This is set to `true` by default + to decode the response body if it comes over the wire with a + `Content-Encoding`. Set this value to `false` to disable decoding the + response content, and pass a string to provide a request `Accept-Encoding` + header and turn on automatic response decoding. This feature now allows you + to pass an `Accept-Encoding` header in the headers of a request but still + disable automatic response decoding. + Closes https://github.com/guzzle/guzzle/issues/764 +* Added the ability to throw an exception immediately when transferring + requests in parallel. Closes https://github.com/guzzle/guzzle/issues/760 +* Updating guzzlehttp/streams dependency to ~2.1 +* No longer utilizing the now deprecated namespaced methods from the stream + package. + +## 4.1.8 - 2014-08-14 + +* Fixed an issue in the CurlFactory that caused setting the `stream=false` + request option to throw an exception. + See: https://github.com/guzzle/guzzle/issues/769 +* TransactionIterator now calls rewind on the inner iterator. + See: https://github.com/guzzle/guzzle/pull/765 +* You can now set the `Content-Type` header to `multipart/form-data` + when creating POST requests to force multipart bodies. + See https://github.com/guzzle/guzzle/issues/768 + +## 4.1.7 - 2014-08-07 + +* Fixed an error in the HistoryPlugin that caused the same request and response + to be logged multiple times when an HTTP protocol error occurs. +* Ensuring that cURL does not add a default Content-Type when no Content-Type + has been supplied by the user. This prevents the adapter layer from modifying + the request that is sent over the wire after any listeners may have already + put the request in a desired state (e.g., signed the request). +* Throwing an exception when you attempt to send requests that have the + "stream" set to true in parallel using the MultiAdapter. +* Only calling curl_multi_select when there are active cURL handles. This was + previously changed and caused performance problems on some systems due to PHP + always selecting until the maximum select timeout. +* Fixed a bug where multipart/form-data POST fields were not correctly + aggregated (e.g., values with "&"). + +## 4.1.6 - 2014-08-03 + +* Added helper methods to make it easier to represent messages as strings, + including getting the start line and getting headers as a string. + +## 4.1.5 - 2014-08-02 + +* Automatically retrying cURL "Connection died, retrying a fresh connect" + errors when possible. +* cURL implementation cleanup +* Allowing multiple event subscriber listeners to be registered per event by + passing an array of arrays of listener configuration. + +## 4.1.4 - 2014-07-22 + +* Fixed a bug that caused multi-part POST requests with more than one field to + serialize incorrectly. +* Paths can now be set to "0" +* `ResponseInterface::xml` now accepts a `libxml_options` option and added a + missing default argument that was required when parsing XML response bodies. +* A `save_to` stream is now created lazily, which means that files are not + created on disk unless a request succeeds. + +## 4.1.3 - 2014-07-15 + +* Various fixes to multipart/form-data POST uploads +* Wrapping function.php in an if-statement to ensure Guzzle can be used + globally and in a Composer install +* Fixed an issue with generating and merging in events to an event array +* POST headers are only applied before sending a request to allow you to change + the query aggregator used before uploading +* Added much more robust query string parsing +* Fixed various parsing and normalization issues with URLs +* Fixing an issue where multi-valued headers were not being utilized correctly + in the StreamAdapter + +## 4.1.2 - 2014-06-18 + +* Added support for sending payloads with GET requests + +## 4.1.1 - 2014-06-08 + +* Fixed an issue related to using custom message factory options in subclasses +* Fixed an issue with nested form fields in a multi-part POST +* Fixed an issue with using the `json` request option for POST requests +* Added `ToArrayInterface` to `GuzzleHttp\Cookie\CookieJar` + +## 4.1.0 - 2014-05-27 + +* Added a `json` request option to easily serialize JSON payloads. +* Added a `GuzzleHttp\json_decode()` wrapper to safely parse JSON. +* Added `setPort()` and `getPort()` to `GuzzleHttp\Message\RequestInterface`. +* Added the ability to provide an emitter to a client in the client constructor. +* Added the ability to persist a cookie session using $_SESSION. +* Added a trait that can be used to add event listeners to an iterator. +* Removed request method constants from RequestInterface. +* Fixed warning when invalid request start-lines are received. +* Updated MessageFactory to work with custom request option methods. +* Updated cacert bundle to latest build. + +4.0.2 (2014-04-16) +------------------ + +* Proxy requests using the StreamAdapter now properly use request_fulluri (#632) +* Added the ability to set scalars as POST fields (#628) + +## 4.0.1 - 2014-04-04 + +* The HTTP status code of a response is now set as the exception code of + RequestException objects. +* 303 redirects will now correctly switch from POST to GET requests. +* The default parallel adapter of a client now correctly uses the MultiAdapter. +* HasDataTrait now initializes the internal data array as an empty array so + that the toArray() method always returns an array. + +## 4.0.0 - 2014-03-29 + +* For information on changes and upgrading, see: + https://github.com/guzzle/guzzle/blob/master/UPGRADING.md#3x-to-40 +* Added `GuzzleHttp\batch()` as a convenience function for sending requests in + parallel without needing to write asynchronous code. +* Restructured how events are added to `GuzzleHttp\ClientInterface::sendAll()`. + You can now pass a callable or an array of associative arrays where each + associative array contains the "fn", "priority", and "once" keys. + +## 4.0.0.rc-2 - 2014-03-25 + +* Removed `getConfig()` and `setConfig()` from clients to avoid confusion + around whether things like base_url, message_factory, etc. should be able to + be retrieved or modified. +* Added `getDefaultOption()` and `setDefaultOption()` to ClientInterface +* functions.php functions were renamed using snake_case to match PHP idioms +* Added support for `HTTP_PROXY`, `HTTPS_PROXY`, and + `GUZZLE_CURL_SELECT_TIMEOUT` environment variables +* Added the ability to specify custom `sendAll()` event priorities +* Added the ability to specify custom stream context options to the stream + adapter. +* Added a functions.php function for `get_path()` and `set_path()` +* CurlAdapter and MultiAdapter now use a callable to generate curl resources +* MockAdapter now properly reads a body and emits a `headers` event +* Updated Url class to check if a scheme and host are set before adding ":" + and "//".

Any +HTTP message interaction (e.g., `GuzzleHttp\Message\Request`) need to be +updated to work with the new immutable PSR-7 request and response objects. Any +event listeners or subscribers need to be updated to become middleware +functions that wrap handlers (or are injected into a +`GuzzleHttp\HandlerStack`). + +- Removed `GuzzleHttp\BatchResults` +- Removed `GuzzleHttp\Collection` +- Removed `GuzzleHttp\HasDataTrait` +- Removed `GuzzleHttp\ToArrayInterface` +- The `guzzlehttp/streams` dependency has been removed. Stream functionality + is now present in the `GuzzleHttp\Psr7` namespace provided by the + `guzzlehttp/psr7` package. +- Guzzle no longer uses ReactPHP promises and now uses the + `guzzlehttp/promises` library. We use a custom promise library for three + significant reasons: + 1. React promises (at the time of writing this) are recursive. Promise + chaining and promise resolution will eventually blow the stack. Guzzle + promises are not recursive as they use a sort of trampolining technique. + Note: there has been movement in the React project to modify promises to + no longer utilize recursion. + 2. Guzzle needs to have the ability to synchronously block on a promise to + wait for a result. Guzzle promises allows this functionality (and does + not require the use of recursion). + 3. Because we need to be able to wait on a result, doing so using React + promises requires wrapping react promises with RingPHP futures. This + overhead is no longer needed, reducing stack sizes, reducing complexity, + and improving performance. +- `GuzzleHttp\Mimetypes` has been moved to a function in + `GuzzleHttp\Psr7\mimetype_from_extension` and + `GuzzleHttp\Psr7\mimetype_from_filename`. +- `GuzzleHttp\Query` and `GuzzleHttp\QueryParser` have been removed. Query + strings must now be passed into request objects as strings, or provided to + the `query` request option when creating requests with clients. The `query` + option uses PHP's `http_build_query` to convert an array to a string. If you + need a different serialization technique, you will need to pass the query + string in as a string. There are a couple helper functions that will make + working with query strings easier: `GuzzleHttp\Psr7\parse_query` and + `GuzzleHttp\Psr7\build_query`. +- Guzzle no longer has a dependency on RingPHP. Due to the use of a middleware + system based on PSR-7, using RingPHP and it's middleware system as well adds + more complexity than the benefits it provides. All HTTP handlers that were + present in RingPHP have been modified to work directly with PSR-7 messages + and placed in the `GuzzleHttp\Handler` namespace. This significantly reduces + complexity in Guzzle, removes a dependency, and improves performance. RingPHP + will be maintained for Guzzle 5 support, but will no longer be a part of + Guzzle 6. +- As Guzzle now uses a middleware based systems the event system and RingPHP + integration has been removed. Note: while the event system has been removed, + it is possible to add your own type of event system that is powered by the + middleware system. + - Removed the `Event` namespace. + - Removed the `Subscriber` namespace. + - Removed `Transaction` class + - Removed `RequestFsm` + - Removed `RingBridge` + - `GuzzleHttp\Subscriber\Cookie` is now provided by + `GuzzleHttp\Middleware::cookies` + - `GuzzleHttp\Subscriber\HttpError` is now provided by + `GuzzleHttp\Middleware::httpError` + - `GuzzleHttp\Subscriber\History` is now provided by + `GuzzleHttp\Middleware::history` + - `GuzzleHttp\Subscriber\Mock` is now provided by + `GuzzleHttp\Handler\MockHandler` + - `GuzzleHttp\Subscriber\Prepare` is now provided by + `GuzzleHttp\PrepareBodyMiddleware` + - `GuzzleHttp\Subscriber\Redirect` is now provided by + `GuzzleHttp\RedirectMiddleware` +- Guzzle now uses `Psr\Http\Message\UriInterface` (implements in + `GuzzleHttp\Psr7\Uri`) for URI support. `GuzzleHttp\Url` is now gone. +- Static functions in `GuzzleHttp\Utils` have been moved to namespaced + functions under the `GuzzleHttp` namespace. This requires either a Composer + based autoloader or you to include functions.php. +- `GuzzleHttp\ClientInterface::getDefaultOption` has been renamed to + `GuzzleHttp\ClientInterface::getConfig`. +- `GuzzleHttp\ClientInterface::setDefaultOption` has been removed. +- The `json` and `xml` methods of response objects has been removed. With the + migration to strictly adhering to PSR-7 as the interface for Guzzle messages, + adding methods to message interfaces would actually require Guzzle messages + to extend from PSR-7 messages rather then work with them directly. + +## Migrating to middleware + +The change to PSR-7 unfortunately required significant refactoring to Guzzle +due to the fact that PSR-7 messages are immutable. Guzzle 5 relied on an event +system from plugins. The event system relied on mutability of HTTP messages and +side effects in order to work. With immutable messages, you have to change your +workflow to become more about either returning a value (e.g., functional +middlewares) or setting a value on an object. Guzzle v6 has chosen the +functional middleware approach. + +Instead of using the event system to listen for things like the `before` event, +you now create a stack based middleware function that intercepts a request on +the way in and the promise of the response on the way out. This is a much +simpler and more predictable approach than the event system and works nicely +with PSR-7 middleware. Due to the use of promises, the middleware system is +also asynchronous. + +v5: + +```php +use GuzzleHttp\Event\BeforeEvent; +$client = new GuzzleHttp\Client(); +// Get the emitter and listen to the before event. +$client->getEmitter()->on('before', function (BeforeEvent $e) { + // Guzzle v5 events relied on mutation + $e->getRequest()->setHeader('X-Foo', 'Bar'); +}); +``` + +v6: + +In v6, you can modify the request before it is sent using the `mapRequest` +middleware. The idiomatic way in v6 to modify the request/response lifecycle is +to setup a handler middleware stack up front and inject the handler into a +client. + +```php +use GuzzleHttp\Middleware; +// Create a handler stack that has all of the default middlewares attached +$handler = GuzzleHttp\HandlerStack::create(); +// Push the handler onto the handler stack +$handler->push(Middleware::mapRequest(function (RequestInterface $request) { + // Notice that we have to return a request object + return $request->withHeader('X-Foo', 'Bar'); +})); +// Inject the handler into the client +$client = new GuzzleHttp\Client(['handler' => $handler]); +``` + +## POST Requests + +This version added the [`form_params`](http://guzzle.readthedocs.org/en/latest/request-options.html#form_params) +and `multipart` request options. `form_params` is an associative array of +strings or array of strings and is used to serialize an +`application/x-www-form-urlencoded` POST request. The +[`multipart`](http://guzzle.readthedocs.org/en/latest/request-options.html#multipart) +option is now used to send a multipart/form-data POST request. + +`GuzzleHttp\Post\PostFile` has been removed. Use the `multipart` option to add +POST files to a multipart/form-data request. + +The `body` option no longer accepts an array to send POST requests. Please use +`multipart` or `form_params` instead. + +The `base_url` option has been renamed to `base_uri`. + +4.x to 5.0 +---------- + +## Rewritten Adapter Layer + +Guzzle now uses [RingPHP](http://ringphp.readthedocs.org/en/latest) to send +HTTP requests. The `adapter` option in a `GuzzleHttp\Client` constructor +is still supported, but it has now been renamed to `handler`. Instead of +passing a `GuzzleHttp\Adapter\AdapterInterface`, you must now pass a PHP +`callable` that follows the RingPHP specification. + +## Removed Fluent Interfaces + +[Fluent interfaces were removed](https://ocramius.github.io/blog/fluent-interfaces-are-evil/) +from the following classes: + +- `GuzzleHttp\Collection` +- `GuzzleHttp\Url` +- `GuzzleHttp\Query` +- `GuzzleHttp\Post\PostBody` +- `GuzzleHttp\Cookie\SetCookie` + +## Removed functions.php + +Removed "functions.php", so that Guzzle is truly PSR-4 compliant. The following +functions can be used as replacements. + +- `GuzzleHttp\json_decode` -> `GuzzleHttp\Utils::jsonDecode` +- `GuzzleHttp\get_path` -> `GuzzleHttp\Utils::getPath` +- `GuzzleHttp\Utils::setPath` -> `GuzzleHttp\set_path` +- `GuzzleHttp\Pool::batch` -> `GuzzleHttp\batch`. This function is, however, + deprecated in favor of using `GuzzleHttp\Pool::batch()`. + +The "procedural" global client has been removed with no replacement (e.g., +`GuzzleHttp\get()`, `GuzzleHttp\post()`, etc.). Use a `GuzzleHttp\Client` +object as a replacement. + +## `throwImmediately` has been removed + +The concept of "throwImmediately" has been removed from exceptions and error +events. This control mechanism was used to stop a transfer of concurrent +requests from completing. This can now be handled by throwing the exception or +by cancelling a pool of requests or each outstanding future request +individually. + +## headers event has been removed + +Removed the "headers" event. This event was only useful for changing the +body a response once the headers of the response were known. You can implement +a similar behavior in a number of ways. One example might be to use a +FnStream that has access to the transaction being sent. For example, when the +first byte is written, you could check if the response headers match your +expectations, and if so, change the actual stream body that is being +written to. + +## Updates to HTTP Messages + +Removed the `asArray` parameter from +`GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header +value as an array, then use the newly added `getHeaderAsArray()` method of +`MessageInterface`. This change makes the Guzzle interfaces compatible with +the PSR-7 interfaces. + +3.x to 4.0 +---------- + +## Overarching changes: + +- Now requires PHP 5.4 or greater. +- No longer requires cURL to send requests. +- Guzzle no longer wraps every exception it throws. Only exceptions that are + recoverable are now wrapped by Guzzle. +- Various namespaces have been removed or renamed. +- No longer requiring the Symfony EventDispatcher. A custom event dispatcher + based on the Symfony EventDispatcher is + now utilized in `GuzzleHttp\Event\EmitterInterface` (resulting in significant + speed and functionality improvements). + +Changes per Guzzle 3.x namespace are described below. + +## Batch + +The `Guzzle\Batch` namespace has been removed. This is best left to +third-parties to implement on top of Guzzle's core HTTP library. + +## Cache + +The `Guzzle\Cache` namespace has been removed. (Todo: No suitable replacement +has been implemented yet, but hoping to utilize a PSR cache interface). + +## Common + +- Removed all of the wrapped exceptions. It's better to use the standard PHP + library for unrecoverable exceptions. +- `FromConfigInterface` has been removed. +- `Guzzle\Common\Version` has been removed. The VERSION constant can be found + at `GuzzleHttp\ClientInterface::VERSION`. + +### Collection + +- `getAll` has been removed. Use `toArray` to convert a collection to an array. +- `inject` has been removed. +- `keySearch` has been removed. +- `getPath` no longer supports wildcard expressions. Use something better like + JMESPath for this. +- `setPath` now supports appending to an existing array via the `[]` notation. + +### Events + +Guzzle no longer requires Symfony's EventDispatcher component. Guzzle now uses +`GuzzleHttp\Event\Emitter`. + +- `Symfony\Component\EventDispatcher\EventDispatcherInterface` is replaced by + `GuzzleHttp\Event\EmitterInterface`. +- `Symfony\Component\EventDispatcher\EventDispatcher` is replaced by + `GuzzleHttp\Event\Emitter`. +- `Symfony\Component\EventDispatcher\Event` is replaced by + `GuzzleHttp\Event\Event`, and Guzzle now has an EventInterface in + `GuzzleHttp\Event\EventInterface`. +- `AbstractHasDispatcher` has moved to a trait, `HasEmitterTrait`, and + `HasDispatcherInterface` has moved to `HasEmitterInterface`. Retrieving the + event emitter of a request, client, etc. now uses the `getEmitter` method + rather than the `getDispatcher` method. + +#### Emitter + +- Use the `once()` method to add a listener that automatically removes itself + the first time it is invoked. +- Use the `listeners()` method to retrieve a list of event listeners rather than + the `getListeners()` method. +- Use `emit()` instead of `dispatch()` to emit an event from an emitter. +- Use `attach()` instead of `addSubscriber()` and `detach()` instead of + `removeSubscriber()`. + +```php +$mock = new Mock(); +// 3.x +$request->getEventDispatcher()->addSubscriber($mock); +$request->getEventDispatcher()->removeSubscriber($mock); +// 4.x +$request->getEmitter()->attach($mock); +$request->getEmitter()->detach($mock); +``` + +Use the `on()` method to add a listener rather than the `addListener()` method. + +```php +// 3.x +$request->getEventDispatcher()->addListener('foo', function (Event $event) { /* ... */ } ); +// 4.x +$request->getEmitter()->on('foo', function (Event $event, $name) { /* ... */ } ); +``` + +## Http + +### General changes + +- The cacert.pem certificate has been moved to `src/cacert.pem`. +- Added the concept of adapters that are used to transfer requests over the + wire. +- Simplified the event system. +- Sending requests in parallel is still possible, but batching is no longer a + concept of the HTTP layer. Instead, you must use the `complete` and `error` + events to asynchronously manage parallel request transfers. +- `Guzzle\Http\Url` has moved to `GuzzleHttp\Url`. +- `Guzzle\Http\QueryString` has moved to `GuzzleHttp\Query`. +- QueryAggregators have been rewritten so that they are simply callable + functions. +- `GuzzleHttp\StaticClient` has been removed. Use the functions provided in + `functions.php` for an easy to use static client instance. +- Exceptions in `GuzzleHttp\Exception` have been updated to all extend from + `GuzzleHttp\Exception\TransferException`. + +### Client + +Calling methods like `get()`, `post()`, `head()`, etc. no longer create and +return a request, but rather creates a request, sends the request, and returns +the response. + +```php +// 3.0 +$request = $client->get('/'); +$response = $request->send(); + +// 4.0 +$response = $client->get('/'); + +// or, to mirror the previous behavior +$request = $client->createRequest('GET', '/'); +$response = $client->send($request); +``` + +`GuzzleHttp\ClientInterface` has changed. + +- The `send` method no longer accepts more than one request. Use `sendAll` to + send multiple requests in parallel. +- `setUserAgent()` has been removed. Use a default request option instead. You + could, for example, do something like: + `$client->setConfig('defaults/headers/User-Agent', 'Foo/Bar ' . $client::getDefaultUserAgent())`. +- `setSslVerification()` has been removed. Use default request options instead, + like `$client->setConfig('defaults/verify', true)`. + +`GuzzleHttp\Client` has changed. + +- The constructor now accepts only an associative array. You can include a + `base_url` string or array to use a URI template as the base URL of a client. + You can also specify a `defaults` key that is an associative array of default + request options. You can pass an `adapter` to use a custom adapter, + `batch_adapter` to use a custom adapter for sending requests in parallel, or + a `message_factory` to change the factory used to create HTTP requests and + responses. +- The client no longer emits a `client.create_request` event. +- Creating requests with a client no longer automatically utilize a URI + template. You must pass an array into a creational method (e.g., + `createRequest`, `get`, `put`, etc.) in order to expand a URI template. + +### Messages + +Messages no longer have references to their counterparts (i.e., a request no +longer has a reference to it's response, and a response no loger has a +reference to its request). This association is now managed through a +`GuzzleHttp\Adapter\TransactionInterface` object. You can get references to +these transaction objects using request events that are emitted over the +lifecycle of a request. + +#### Requests with a body + +- `GuzzleHttp\Message\EntityEnclosingRequest` and + `GuzzleHttp\Message\EntityEnclosingRequestInterface` have been removed. The + separation between requests that contain a body and requests that do not + contain a body has been removed, and now `GuzzleHttp\Message\RequestInterface` + handles both use cases. +- Any method that previously accepts a `GuzzleHttp\Response` object now accept a + `GuzzleHttp\Message\ResponseInterface`. +- `GuzzleHttp\Message\RequestFactoryInterface` has been renamed to + `GuzzleHttp\Message\MessageFactoryInterface`. This interface is used to create + both requests and responses and is implemented in + `GuzzleHttp\Message\MessageFactory`. +- POST field and file methods have been removed from the request object. You + must now use the methods made available to `GuzzleHttp\Post\PostBodyInterface` + to control the format of a POST body. Requests that are created using a + standard `GuzzleHttp\Message\MessageFactoryInterface` will automatically use + a `GuzzleHttp\Post\PostBody` body if the body was passed as an array or if + the method is POST and no body is provided. + +```php +$request = $client->createRequest('POST', '/'); +$request->getBody()->setField('foo', 'bar'); +$request->getBody()->addFile(new PostFile('file_key', fopen('/path/to/content', 'r'))); +``` + +#### Headers + +- `GuzzleHttp\Message\Header` has been removed. Header values are now simply + represented by an array of values or as a string. Header values are returned + as a string by default when retrieving a header value from a message. You can + pass an optional argument of `true` to retrieve a header value as an array + of strings instead of a single concatenated string. +- `GuzzleHttp\PostFile` and `GuzzleHttp\PostFileInterface` have been moved to + `GuzzleHttp\Post`. This interface has been simplified and now allows the + addition of arbitrary headers. +- Custom headers like `GuzzleHttp\Message\Header\Link` have been removed. Most + of the custom headers are now handled separately in specific + subscribers/plugins, and `GuzzleHttp\Message\HeaderValues::parseParams()` has + been updated to properly handle headers that contain parameters (like the + `Link` header). + +#### Responses + +- `GuzzleHttp\Message\Response::getInfo()` and + `GuzzleHttp\Message\Response::setInfo()` have been removed. Use the event + system to retrieve this type of information. +- `GuzzleHttp\Message\Response::getRawHeaders()` has been removed. +- `GuzzleHttp\Message\Response::getMessage()` has been removed. +- `GuzzleHttp\Message\Response::calculateAge()` and other cache specific + methods have moved to the CacheSubscriber. +- Header specific helper functions like `getContentMd5()` have been removed. + Just use `getHeader('Content-MD5')` instead. +- `GuzzleHttp\Message\Response::setRequest()` and + `GuzzleHttp\Message\Response::getRequest()` have been removed. Use the event + system to work with request and response objects as a transaction. +- `GuzzleHttp\Message\Response::getRedirectCount()` has been removed. Use the + Redirect subscriber instead. +- `GuzzleHttp\Message\Response::isSuccessful()` and other related methods have + been removed. Use `getStatusCode()` instead. + +#### Streaming responses + +Streaming requests can now be created by a client directly, returning a +`GuzzleHttp\Message\ResponseInterface` object that contains a body stream +referencing an open PHP HTTP stream. + +```php +// 3.0 +use Guzzle\Stream\PhpStreamRequestFactory; +$request = $client->get('/'); +$factory = new PhpStreamRequestFactory(); +$stream = $factory->fromRequest($request); +$data = $stream->read(1024); + +// 4.0 +$response = $client->get('/', ['stream' => true]); +// Read some data off of the stream in the response body +$data = $response->getBody()->read(1024); +``` + +#### Redirects + +The `configureRedirects()` method has been removed in favor of a +`allow_redirects` request option. + +```php +// Standard redirects with a default of a max of 5 redirects +$request = $client->createRequest('GET', '/', ['allow_redirects' => true]); + +// Strict redirects with a custom number of redirects +$request = $client->createRequest('GET', '/', [ + 'allow_redirects' => ['max' => 5, 'strict' => true] +]); +``` + +#### EntityBody + +EntityBody interfaces and classes have been removed or moved to +`GuzzleHttp\Stream`. All classes and interfaces that once required +`GuzzleHttp\EntityBodyInterface` now require +`GuzzleHttp\Stream\StreamInterface`. Creating a new body for a request no +longer uses `GuzzleHttp\EntityBody::factory` but now uses +`GuzzleHttp\Stream\Stream::factory` or even better: +`GuzzleHttp\Stream\create()`. + +- `Guzzle\Http\EntityBodyInterface` is now `GuzzleHttp\Stream\StreamInterface` +- `Guzzle\Http\EntityBody` is now `GuzzleHttp\Stream\Stream` +- `Guzzle\Http\CachingEntityBody` is now `GuzzleHttp\Stream\CachingStream` +- `Guzzle\Http\ReadLimitEntityBody` is now `GuzzleHttp\Stream\LimitStream` +- `Guzzle\Http\IoEmittyinEntityBody` has been removed. + +#### Request lifecycle events + +Requests previously submitted a large number of requests. The number of events +emitted over the lifecycle of a request has been significantly reduced to make +it easier to understand how to extend the behavior of a request. All events +emitted during the lifecycle of a request now emit a custom +`GuzzleHttp\Event\EventInterface` object that contains context providing +methods and a way in which to modify the transaction at that specific point in +time (e.g., intercept the request and set a response on the transaction). + +- `request.before_send` has been renamed to `before` and now emits a + `GuzzleHttp\Event\BeforeEvent` +- `request.complete` has been renamed to `complete` and now emits a + `GuzzleHttp\Event\CompleteEvent`. +- `request.sent` has been removed. Use `complete`. +- `request.success` has been removed. Use `complete`. +- `error` is now an event that emits a `GuzzleHttp\Event\ErrorEvent`. +- `request.exception` has been removed. Use `error`. +- `request.receive.status_line` has been removed. +- `curl.callback.progress` has been removed. Use a custom `StreamInterface` to + maintain a status update. +- `curl.callback.write` has been removed. Use a custom `StreamInterface` to + intercept writes. +- `curl.callback.read` has been removed. Use a custom `StreamInterface` to + intercept reads. + +`headers` is a new event that is emitted after the response headers of a +request have been received before the body of the response is downloaded. This +event emits a `GuzzleHttp\Event\HeadersEvent`. + +You can intercept a request and inject a response using the `intercept()` event +of a `GuzzleHttp\Event\BeforeEvent`, `GuzzleHttp\Event\CompleteEvent`, and +`GuzzleHttp\Event\ErrorEvent` event. + +See: http://docs.guzzlephp.org/en/latest/events.html + +## Inflection + +The `Guzzle\Inflection` namespace has been removed. This is not a core concern +of Guzzle. + +## Iterator + +The `Guzzle\Iterator` namespace has been removed. + +- `Guzzle\Iterator\AppendIterator`, `Guzzle\Iterator\ChunkedIterator`, and + `Guzzle\Iterator\MethodProxyIterator` are nice, but not a core requirement of + Guzzle itself. +- `Guzzle\Iterator\FilterIterator` is no longer needed because an equivalent + class is shipped with PHP 5.4. +- `Guzzle\Iterator\MapIterator` is not really needed when using PHP 5.5 because + it's easier to just wrap an iterator in a generator that maps values. + +For a replacement of these iterators, see https://github.com/nikic/iter + +## Log + +The LogPlugin has moved to https://github.com/guzzle/log-subscriber. The +`Guzzle\Log` namespace has been removed. Guzzle now relies on +`Psr\Log\LoggerInterface` for all logging. The MessageFormatter class has been +moved to `GuzzleHttp\Subscriber\Log\Formatter`. + +## Parser + +The `Guzzle\Parser` namespace has been removed. This was previously used to +make it possible to plug in custom parsers for cookies, messages, URI +templates, and URLs; however, this level of complexity is not needed in Guzzle +so it has been removed. + +- Cookie: Cookie parsing logic has been moved to + `GuzzleHttp\Cookie\SetCookie::fromString`. +- Message: Message parsing logic for both requests and responses has been moved + to `GuzzleHttp\Message\MessageFactory::fromMessage`. Message parsing is only + used in debugging or deserializing messages, so it doesn't make sense for + Guzzle as a library to add this level of complexity to parsing messages. +- UriTemplate: URI template parsing has been moved to + `GuzzleHttp\UriTemplate`. The Guzzle library will automatically use the PECL + URI template library if it is installed. +- Url: URL parsing is now performed in `GuzzleHttp\Url::fromString` (previously + it was `Guzzle\Http\Url::factory()`). If custom URL parsing is necessary, + then developers are free to subclass `GuzzleHttp\Url`. + +## Plugin + +The `Guzzle\Plugin` namespace has been renamed to `GuzzleHttp\Subscriber`. +Several plugins are shipping with the core Guzzle library under this namespace. + +- `GuzzleHttp\Subscriber\Cookie`: Replaces the old CookiePlugin. Cookie jar + code has moved to `GuzzleHttp\Cookie`. +- `GuzzleHttp\Subscriber\History`: Replaces the old HistoryPlugin. +- `GuzzleHttp\Subscriber\HttpError`: Throws errors when a bad HTTP response is + received. +- `GuzzleHttp\Subscriber\Mock`: Replaces the old MockPlugin. +- `GuzzleHttp\Subscriber\Prepare`: Prepares the body of a request just before + sending. This subscriber is attached to all requests by default. +- `GuzzleHttp\Subscriber\Redirect`: Replaces the RedirectPlugin. + +The following plugins have been removed (third-parties are free to re-implement +these if needed): + +- `GuzzleHttp\Plugin\Async` has been removed. +- `GuzzleHttp\Plugin\CurlAuth` has been removed. +- `GuzzleHttp\Plugin\ErrorResponse\ErrorResponsePlugin` has been removed. This + functionality should instead be implemented with event listeners that occur + after normal response parsing occurs in the guzzle/command package. + +The following plugins are not part of the core Guzzle package, but are provided +in separate repositories: + +- `Guzzle\Http\Plugin\BackoffPlugin` has been rewritten to be much simpler + to build custom retry policies using simple functions rather than various + chained classes. See: https://github.com/guzzle/retry-subscriber +- `Guzzle\Http\Plugin\Cache\CachePlugin` has moved to + https://github.com/guzzle/cache-subscriber +- `Guzzle\Http\Plugin\Log\LogPlugin` has moved to + https://github.com/guzzle/log-subscriber +- `Guzzle\Http\Plugin\Md5\Md5Plugin` has moved to + https://github.com/guzzle/message-integrity-subscriber +- `Guzzle\Http\Plugin\Mock\MockPlugin` has moved to + `GuzzleHttp\Subscriber\MockSubscriber`. +- `Guzzle\Http\Plugin\Oauth\OauthPlugin` has moved to + https://github.com/guzzle/oauth-subscriber + +## Service + +The service description layer of Guzzle has moved into two separate packages: + +- http://github.com/guzzle/command Provides a high level abstraction over web + services by representing web service operations using commands. +- http://github.com/guzzle/guzzle-services Provides an implementation of + guzzle/command that provides request serialization and response parsing using + Guzzle service descriptions. + +## Stream + +Stream have moved to a separate package available at +https://github.com/guzzle/streams. + +`Guzzle\Stream\StreamInterface` has been given a large update to cleanly take +on the responsibilities of `Guzzle\Http\EntityBody` and +`Guzzle\Http\EntityBodyInterface` now that they have been removed. The number +of methods implemented by the `StreamInterface` has been drastically reduced to +allow developers to more easily extend and decorate stream behavior. + +## Removed methods from StreamInterface + +- `getStream` and `setStream` have been removed to better encapsulate streams. +- `getMetadata` and `setMetadata` have been removed in favor of + `GuzzleHttp\Stream\MetadataStreamInterface`. +- `getWrapper`, `getWrapperData`, `getStreamType`, and `getUri` have all been + removed. This data is accessible when + using streams that implement `GuzzleHttp\Stream\MetadataStreamInterface`. +- `rewind` has been removed. Use `seek(0)` for a similar behavior. + +## Renamed methods + +- `detachStream` has been renamed to `detach`. +- `feof` has been renamed to `eof`. +- `ftell` has been renamed to `tell`. +- `readLine` has moved from an instance method to a static class method of + `GuzzleHttp\Stream\Stream`. + +## Metadata streams + +`GuzzleHttp\Stream\MetadataStreamInterface` has been added to denote streams +that contain additional metadata accessible via `getMetadata()`. +`GuzzleHttp\Stream\StreamInterface::getMetadata` and +`GuzzleHttp\Stream\StreamInterface::setMetadata` have been removed. + +## StreamRequestFactory + +The entire concept of the StreamRequestFactory has been removed. The way this +was used in Guzzle 3 broke the actual interface of sending streaming requests +(instead of getting back a Response, you got a StreamInterface). Streaming +PHP requests are now implemented through the `GuzzleHttp\Adapter\StreamAdapter`. + +3.6 to 3.7 +---------- + +### Deprecations + +- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.: + +```php +\Guzzle\Common\Version::$emitWarnings = true; +``` + +The following APIs and options have been marked as deprecated: + +- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated.

This is an implementation detail. +- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail. +- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail. +- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin. +- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin. +- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin. + +### Cache plugin breaking changes + +- CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a + CacheStorageInterface. These two objects and interface will be removed in a future version. +- Always setting X-cache headers on cached responses +- Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin +- `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface + $request, Response $response);` +- `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);` +- `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);` +- Added `CacheStorageInterface::purge($url)` +- `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin + $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache, + CanCacheStrategyInterface $canCache = null)` +- Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)` + +3.5 to 3.6 +---------- + +* Mixed casing of headers are now forced to be a single consistent casing across all values for that header. +* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution +* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader(). + For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader(). + Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request. +* Specific header implementations can be created for complex headers. When a message creates a header, it uses a + HeaderFactory which can map specific headers to specific header classes.

Resolving a promises triggers callbacks +registered with the promises's `then` method. These callbacks are triggered +only once and in the order in which they were added. + + +## Resolving a promise + +Promises are fulfilled using the `resolve($value)` method. Resolving a promise +with any value other than a `GuzzleHttp\Promise\RejectedPromise` will trigger +all of the onFulfilled callbacks (resolving a promise with a rejected promise +will reject the promise and trigger the `$onRejected` callbacks). + +```php +use GuzzleHttp\Promise\Promise; + +$promise = new Promise(); +$promise + ->then(function ($value) { + // Return a value and don't break the chain + return "Hello, " . $value; + }) + // This then is executed after the first then and receives the value + // returned from the first then. + ->then(function ($value) { + echo $value; + }); + +// Resolving the promise triggers the $onFulfilled callbacks and outputs +// "Hello, reader." +$promise->resolve('reader.'); +``` + + +## Promise forwarding + +Promises can be chained one after the other. Each then in the chain is a new +promise. The return value of a promise is what's forwarded to the next +promise in the chain. Returning a promise in a `then` callback will cause the +subsequent promises in the chain to only be fulfilled when the returned promise +has been fulfilled. The next promise in the chain will be invoked with the +resolved value of the promise. + +```php +use GuzzleHttp\Promise\Promise; + +$promise = new Promise(); +$nextPromise = new Promise(); + +$promise + ->then(function ($value) use ($nextPromise) { + echo $value; + return $nextPromise; + }) + ->then(function ($value) { + echo $value; + }); + +// Triggers the first callback and outputs "A" +$promise->resolve('A'); +// Triggers the second callback and outputs "B" +$nextPromise->resolve('B'); +``` + +## Promise rejection + +When a promise is rejected, the `$onRejected` callbacks are invoked with the +rejection reason. + +```php +use GuzzleHttp\Promise\Promise; + +$promise = new Promise(); +$promise->then(null, function ($reason) { + echo $reason; +}); + +$promise->reject('Error!'); +// Outputs "Error!" +``` + +## Rejection forwarding + +If an exception is thrown in an `$onRejected` callback, subsequent +`$onRejected` callbacks are invoked with the thrown exception as the reason. + +```php +use GuzzleHttp\Promise\Promise; + +$promise = new Promise(); +$promise->then(null, function ($reason) { + throw new Exception($reason); +})->then(null, function ($reason) { + assert($reason->getMessage() === 'Error!'); +}); + +$promise->reject('Error!'); +``` + +You can also forward a rejection down the promise chain by returning a +`GuzzleHttp\Promise\RejectedPromise` in either an `$onFulfilled` or +`$onRejected` callback. + +```php +use GuzzleHttp\Promise\Promise; +use GuzzleHttp\Promise\RejectedPromise; + +$promise = new Promise(); +$promise->then(null, function ($reason) { + return new RejectedPromise($reason); +})->then(null, function ($reason) { + assert($reason === 'Error!'); +}); + +$promise->reject('Error!'); +``` + +If an exception is not thrown in a `$onRejected` callback and the callback +does not return a rejected promise, downstream `$onFulfilled` callbacks are +invoked using the value returned from the `$onRejected` callback. + +```php +use GuzzleHttp\Promise\Promise; + +$promise = new Promise(); +$promise + ->then(null, function ($reason) { + return "It's ok"; + }) + ->then(function ($value) { + assert($value === "It's ok"); + }); + +$promise->reject('Error!'); +``` + +# Synchronous wait + +You can synchronously force promises to complete using a promise's `wait` +method. When creating a promise, you can provide a wait function that is used +to synchronously force a promise to complete. When a wait function is invoked +it is expected to deliver a value to the promise or reject the promise. If the +wait function does not deliver a value, then an exception is thrown. The wait +function provided to a promise constructor is invoked when the `wait` function +of the promise is called. + +```php +$promise = new Promise(function () use (&$promise) { + $promise->resolve('foo'); +}); + +// Calling wait will return the value of the promise. +echo $promise->wait(); // outputs "foo" +``` + +If an exception is encountered while invoking the wait function of a promise, +the promise is rejected with the exception and the exception is thrown. + +```php +$promise = new Promise(function () use (&$promise) { + throw new Exception('foo'); +}); + +$promise->wait(); // throws the exception. +``` + +Calling `wait` on a promise that has been fulfilled will not trigger the wait +function. It will simply return the previously resolved value. + +```php +$promise = new Promise(function () { die('this is not called!'); }); +$promise->resolve('foo'); +echo $promise->wait(); // outputs "foo" +``` + +Calling `wait` on a promise that has been rejected will throw an exception. If +the rejection reason is an instance of `\Exception` the reason is thrown. +Otherwise, a `GuzzleHttp\Promise\RejectionException` is thrown and the reason +can be obtained by calling the `getReason` method of the exception. + +```php +$promise = new Promise(); +$promise->reject('foo'); +$promise->wait(); +``` + +> PHP Fatal error: Uncaught exception 'GuzzleHttp\Promise\RejectionException' with message 'The promise was rejected with value: foo' + + +## Unwrapping a promise + +When synchronously waiting on a promise, you are joining the state of the +promise into the current state of execution (i.e., return the value of the +promise if it was fulfilled or throw an exception if it was rejected). This is +called "unwrapping" the promise. Waiting on a promise will by default unwrap +the promise state. + +You can force a promise to resolve and *not* unwrap the state of the promise +by passing `false` to the first argument of the `wait` function: + +```php +$promise = new Promise(); +$promise->reject('foo'); +// This will not throw an exception. It simply ensures the promise has +// been resolved. +$promise->wait(false); +``` + +When unwrapping a promise, the resolved value of the promise will be waited +upon until the unwrapped value is not a promise. This means that if you resolve +promise A with a promise B and unwrap promise A, the value returned by the +wait function will be the value delivered to promise B. + +**Note**: when you do not unwrap the promise, no value is returned. + + +# Cancellation + +You can cancel a promise that has not yet been fulfilled using the `cancel()` +method of a promise. When creating a promise you can provide an optional +cancel function that when invoked cancels the action of computing a resolution +of the promise. + + +# API + + +## Promise + +When creating a promise object, you can provide an optional `$waitFn` and +`$cancelFn`. `$waitFn` is a function that is invoked with no arguments and is +expected to resolve the promise. `$cancelFn` is a function with no arguments +that is expected to cancel the computation of a promise. It is invoked when the +`cancel()` method of a promise is called. + +```php +use GuzzleHttp\Promise\Promise; + +$promise = new Promise( + function () use (&$promise) { + $promise->resolve('waited'); + }, + function () { + // do something that will cancel the promise computation (e.g., close + // a socket, cancel a database query, etc...) + } +); + +assert('waited' === $promise->wait()); +``` + +A promise has the following methods: + +- `then(callable $onFulfilled, callable $onRejected) : PromiseInterface` + + Appends fulfillment and rejection handlers to the promise, and returns a new promise resolving to the return value of the called handler. + +- `otherwise(callable $onRejected) : PromiseInterface` + + Appends a rejection handler callback to the promise, and returns a new promise resolving to the return value of the callback if it is called, or to its original fulfillment value if the promise is instead fulfilled. + +- `wait($unwrap = true) : mixed` + + Synchronously waits on the promise to complete. + + `$unwrap` controls whether or not the value of the promise is returned for a + fulfilled promise or if an exception is thrown if the promise is rejected. + This is set to `true` by default. + +- `cancel()` + + Attempts to cancel the promise if possible. The promise being cancelled and + the parent most ancestor that has not yet been resolved will also be + cancelled. Any promises waiting on the cancelled promise to resolve will also + be cancelled. + +- `getState() : string` + + Returns the state of the promise. One of `pending`, `fulfilled`, or + `rejected`. + +- `resolve($value)` + + Fulfills the promise with the given `$value`. + +- `reject($reason)` + + Rejects the promise with the given `$reason`. + + +## FulfilledPromise + +A fulfilled promise can be created to represent a promise that has been +fulfilled. + +```php +use GuzzleHttp\Promise\FulfilledPromise; + +$promise = new FulfilledPromise('value'); + +// Fulfilled callbacks are immediately invoked. +$promise->then(function ($value) { + echo $value; +}); +``` + + +## RejectedPromise + +A rejected promise can be created to represent a promise that has been +rejected. + +```php +use GuzzleHttp\Promise\RejectedPromise; + +$promise = new RejectedPromise('Error'); + +// Rejected callbacks are immediately invoked. +$promise->then(null, function ($reason) { + echo $reason; +}); +``` + + +# Promise interop + +This library works with foreign promises that have a `then` method. This means +you can use Guzzle promises with [React promises](https://github.com/reactphp/promise) +for example. When a foreign promise is returned inside of a then method +callback, promise resolution will occur recursively. + +```php +// Create a React promise +$deferred = new React\Promise\Deferred(); +$reactPromise = $deferred->promise(); + +// Create a Guzzle promise that is fulfilled with a React promise. +$guzzlePromise = new GuzzleHttp\Promise\Promise(); +$guzzlePromise->then(function ($value) use ($reactPromise) { + // Do something something with the value... + // Return the React promise + return $reactPromise; +}); +``` + +Please note that wait and cancel chaining is no longer possible when forwarding +a foreign promise. You will need to wrap a third-party promise with a Guzzle +promise in order to utilize wait and cancel functions with foreign promises. + + +## Event Loop Integration + +In order to keep the stack size constant, Guzzle promises are resolved +asynchronously using a task queue. When waiting on promises synchronously, the +task queue will be automatically run to ensure that the blocking promise and +any forwarded promises are resolved. When using promises asynchronously in an +event loop, you will need to run the task queue on each tick of the loop. If +you do not run the task queue, then promises will not be resolved. + +You can run the task queue using the `run()` method of the global task queue +instance. + +```php +// Get the global task queue +$queue = GuzzleHttp\Promise\Utils::queue(); +$queue->run(); +``` + +For example, you could use Guzzle promises with React using a periodic timer: + +```php +$loop = React\EventLoop\Factory::create(); +$loop->addPeriodicTimer(0, [$queue, 'run']); +``` + +*TODO*: Perhaps adding a `futureTick()` on each tick would be faster? + + +# Implementation notes + + +## Promise resolution and chaining is handled iteratively + +By shuffling pending handlers from one owner to another, promises are +resolved iteratively, allowing for "infinite" then chaining. + +```php +then(function ($v) { + // The stack size remains constant (a good thing) + echo xdebug_get_stack_depth() . ', '; + return $v + 1; + }); +} + +$parent->resolve(0); +var_dump($p->wait()); // int(1000) + +``` + +When a promise is fulfilled or rejected with a non-promise value, the promise +then takes ownership of the handlers of each child promise and delivers values +down the chain without using recursion. + +When a promise is resolved with another promise, the original promise transfers +all of its pending handlers to the new promise. When the new promise is +eventually resolved, all of the pending handlers are delivered the forwarded +value. + + +## A promise is the deferred. + +Some promise libraries implement promises using a deferred object to represent +a computation and a promise object to represent the delivery of the result of +the computation. This is a nice separation of computation and delivery because +consumers of the promise cannot modify the value that will be eventually +delivered. + +One side effect of being able to implement promise resolution and chaining +iteratively is that you need to be able for one promise to reach into the state +of another promise to shuffle around ownership of handlers. In order to achieve +this without making the handlers of a promise publicly mutable, a promise is +also the deferred value, allowing promises of the same parent class to reach +into and modify the private properties of promises of the same type. While this +does allow consumers of the value to modify the resolution or rejection of the +deferred, it is a small price to pay for keeping the stack size constant. + +```php +$promise = new Promise(); +$promise->then(function ($value) { echo $value; }); +// The promise is the deferred value, so you can deliver a value to it. +$promise->resolve('foo'); +// prints "foo" +``` + + +## Upgrading from Function API + +A static API was first introduced in 1.4.0, in order to mitigate problems with functions conflicting between global and local copies of the package.

This could be implemented by overriding the +`read()` method. + +```php +use Psr\Http\Message\StreamInterface; +use GuzzleHttp\Psr7\StreamDecoratorTrait; + +class EofCallbackStream implements StreamInterface +{ + use StreamDecoratorTrait; + + private $callback; + + public function __construct(StreamInterface $stream, callable $cb) + { + $this->stream = $stream; + $this->callback = $cb; + } + + public function read($length) + { + $result = $this->stream->read($length); + + // Invoke the callback when EOF is hit. + if ($this->eof()) { + call_user_func($this->callback); + } + + return $result; + } +} +``` + +This decorator could be added to any existing stream and used like so: + +```php +use GuzzleHttp\Psr7; + +$original = Psr7\Utils::streamFor('foo'); + +$eofStream = new EofCallbackStream($original, function () { + echo 'EOF!'; +}); + +$eofStream->read(2); +$eofStream->read(1); +// echoes "EOF!" +$eofStream->seek(0); +$eofStream->read(3); +// echoes "EOF!" +``` + + +## PHP StreamWrapper + +You can use the `GuzzleHttp\Psr7\StreamWrapper` class if you need to use a +PSR-7 stream as a PHP stream resource. + +Use the `GuzzleHttp\Psr7\StreamWrapper::getResource()` method to create a PHP +stream from a PSR-7 stream. + +```php +use GuzzleHttp\Psr7\StreamWrapper; + +$stream = GuzzleHttp\Psr7\Utils::streamFor('hello!'); +$resource = StreamWrapper::getResource($stream); +echo fread($resource, 6); // outputs hello! +``` + + +# Static API + +There are various static methods available under the `GuzzleHttp\Psr7` namespace. + + +## `GuzzleHttp\Psr7\Message::toString` + +`public static function toString(MessageInterface $message): string` + +Returns the string representation of an HTTP message. + +```php +$request = new GuzzleHttp\Psr7\Request('GET', 'http://example.com'); +echo GuzzleHttp\Psr7\Message::toString($request); +``` + + +## `GuzzleHttp\Psr7\Message::bodySummary` + +`public static function bodySummary(MessageInterface $message, int $truncateAt = 120): string|null` + +Get a short summary of the message body. + +Will return `null` if the response is not printable. + + +## `GuzzleHttp\Psr7\Message::rewindBody` + +`public static function rewindBody(MessageInterface $message): void` + +Attempts to rewind a message body and throws an exception on failure. + +The body of the message will only be rewound if a call to `tell()` +returns a value other than `0`. + + +## `GuzzleHttp\Psr7\Message::parseMessage` + +`public static function parseMessage(string $message): array` + +Parses an HTTP message into an associative array. + +The array contains the "start-line" key containing the start line of +the message, "headers" key containing an associative array of header +array values, and a "body" key containing the body of the message. + + +## `GuzzleHttp\Psr7\Message::parseRequestUri` + +`public static function parseRequestUri(string $path, array $headers): string` + +Constructs a URI for an HTTP request message. + + +## `GuzzleHttp\Psr7\Message::parseRequest` + +`public static function parseRequest(string $message): Request` + +Parses a request message string into a request object. + + +## `GuzzleHttp\Psr7\Message::parseResponse` + +`public static function parseResponse(string $message): Response` + +Parses a response message string into a response object. + + +## `GuzzleHttp\Psr7\Header::parse` + +`public static function parse(string|array $header): array` + +Parse an array of header values containing ";" separated data into an +array of associative arrays representing the header key value pair data +of the header.

A relative reference is used to express a URI relative to another URI, +the base URI. Relative references can be divided into several forms according to +[RFC 3986 Section 4.2](https://tools.ietf.org/html/rfc3986#section-4.2): + +- network-path references, e.g. `//example.com/path` +- absolute-path references, e.g. `/path` +- relative-path references, e.g. `subpath` + +The following methods can be used to identify the type of the URI. + +### `GuzzleHttp\Psr7\Uri::isAbsolute` + +`public static function isAbsolute(UriInterface $uri): bool` + +Whether the URI is absolute, i.e. it has a scheme. + +### `GuzzleHttp\Psr7\Uri::isNetworkPathReference` + +`public static function isNetworkPathReference(UriInterface $uri): bool` + +Whether the URI is a network-path reference. A relative reference that begins with two slash characters is +termed an network-path reference. + +### `GuzzleHttp\Psr7\Uri::isAbsolutePathReference` + +`public static function isAbsolutePathReference(UriInterface $uri): bool` + +Whether the URI is a absolute-path reference. A relative reference that begins with a single slash character is +termed an absolute-path reference. + +### `GuzzleHttp\Psr7\Uri::isRelativePathReference` + +`public static function isRelativePathReference(UriInterface $uri): bool` + +Whether the URI is a relative-path reference. A relative reference that does not begin with a slash character is +termed a relative-path reference. + +### `GuzzleHttp\Psr7\Uri::isSameDocumentReference` + +`public static function isSameDocumentReference(UriInterface $uri, UriInterface $base = null): bool` + +Whether the URI is a same-document reference. A same-document reference refers to a URI that is, aside from its +fragment component, identical to the base URI. When no base URI is given, only an empty URI reference +(apart from its fragment) is considered a same-document reference. + +## URI Components + +Additional methods to work with URI components. + +### `GuzzleHttp\Psr7\Uri::isDefaultPort` + +`public static function isDefaultPort(UriInterface $uri): bool` + +Whether the URI has the default port of the current scheme. `Psr\Http\Message\UriInterface::getPort` may return null +or the standard port. This method can be used independently of the implementation. + +### `GuzzleHttp\Psr7\Uri::composeComponents` + +`public static function composeComponents($scheme, $authority, $path, $query, $fragment): string` + +Composes a URI reference string from its various components according to +[RFC 3986 Section 5.3](https://tools.ietf.org/html/rfc3986#section-5.3). Usually this method does not need to be called +manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`. + +### `GuzzleHttp\Psr7\Uri::fromParts` + +`public static function fromParts(array $parts): UriInterface` + +Creates a URI from a hash of [`parse_url`](http://php.net/manual/en/function.parse-url.php) components. + + +### `GuzzleHttp\Psr7\Uri::withQueryValue` + +`public static function withQueryValue(UriInterface $uri, $key, $value): UriInterface` + +Creates a new URI with a specific query string value. Any existing query string values that exactly match the +provided key are removed and replaced with the given key value pair. A value of null will set the query string +key without a value, e.g. "key" instead of "key=value". + +### `GuzzleHttp\Psr7\Uri::withQueryValues` + +`public static function withQueryValues(UriInterface $uri, array $keyValueArray): UriInterface` + +Creates a new URI with multiple query string values. It has the same behavior as `withQueryValue()` but for an +associative array of key => value. + +### `GuzzleHttp\Psr7\Uri::withoutQueryValue` + +`public static function withoutQueryValue(UriInterface $uri, $key): UriInterface` + +Creates a new URI with a specific query string value removed. Any existing query string values that exactly match the +provided key are removed. + +## Reference Resolution + +`GuzzleHttp\Psr7\UriResolver` provides methods to resolve a URI reference in the context of a base URI according +to [RFC 3986 Section 5](https://tools.ietf.org/html/rfc3986#section-5). This is for example also what web browsers +do when resolving a link in a website based on the current request URI. + +### `GuzzleHttp\Psr7\UriResolver::resolve` + +`public static function resolve(UriInterface $base, UriInterface $rel): UriInterface` + +Converts the relative URI into a new URI that is resolved against the base URI. + +### `GuzzleHttp\Psr7\UriResolver::removeDotSegments` + +`public static function removeDotSegments(string $path): string` + +Removes dot segments from a path and returns the new path according to +[RFC 3986 Section 5.2.4](https://tools.ietf.org/html/rfc3986#section-5.2.4). + +### `GuzzleHttp\Psr7\UriResolver::relativize` + +`public static function relativize(UriInterface $base, UriInterface $target): UriInterface` + +Returns the target URI as a relative reference from the base URI. This method is the counterpart to resolve(): + +```php +(string) $target === (string) UriResolver::resolve($base, UriResolver::relativize($base, $target)) +``` + +One use-case is to use the current request URI as base URI and then generate relative links in your documents +to reduce the document size or offer self-contained downloadable document archives. + +```php +$base = new Uri('http://example.com/a/b/'); +echo UriResolver::relativize($base, new Uri('http://example.com/a/b/c')); // prints 'c'. +echo UriResolver::relativize($base, new Uri('http://example.com/a/x/y')); // prints '../x/y'. +echo UriResolver::relativize($base, new Uri('http://example.com/a/b/?q')); // prints '?q'. +echo UriResolver::relativize($base, new Uri('http://example.org/a/b/')); // prints '//example.org/a/b/'. +``` + +## Normalization and Comparison + +`GuzzleHttp\Psr7\UriNormalizer` provides methods to normalize and compare URIs according to +[RFC 3986 Section 6](https://tools.ietf.org/html/rfc3986#section-6). + +### `GuzzleHttp\Psr7\UriNormalizer::normalize` + +`public static function normalize(UriInterface $uri, $flags = self::PRESERVING_NORMALIZATIONS): UriInterface` + +Returns a normalized URI. The scheme and host component are already normalized to lowercase per PSR-7 UriInterface. +This methods adds additional normalizations that can be configured with the `$flags` parameter which is a bitmask +of normalizations to apply. The following normalizations are available: + +- `UriNormalizer::PRESERVING_NORMALIZATIONS` + + Default normalizations which only include the ones that preserve semantics. + +- `UriNormalizer::CAPITALIZE_PERCENT_ENCODING` + + All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive, and should be capitalized. + + Example: `http://example.org/a%c2%b1b` → `http://example.org/a%C2%B1b` + +- `UriNormalizer::DECODE_UNRESERVED_CHARACTERS` + + Decodes percent-encoded octets of unreserved characters. For consistency, percent-encoded octets in the ranges of + ALPHA (%41–%5A and %61–%7A), DIGIT (%30–%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E) should + not be created by URI producers and, when found in a URI, should be decoded to their corresponding unreserved + characters by URI normalizers. + + Example: `http://example.org/%7Eusern%61me/` → `http://example.org/~username/` + +- `UriNormalizer::CONVERT_EMPTY_PATH` + + Converts the empty path to "/" for http and https URIs. + + Example: `http://example.org` → `http://example.org/` + +- `UriNormalizer::REMOVE_DEFAULT_HOST` + + Removes the default host of the given URI scheme from the URI. Only the "file" scheme defines the default host + "localhost". All of `file:/myfile`, `file:///myfile`, and `file://localhost/myfile` are equivalent according to + RFC 3986. + + Example: `file://localhost/myfile` → `file:///myfile` + +- `UriNormalizer::REMOVE_DEFAULT_PORT` + + Removes the default port of the given URI scheme from the URI. + + Example: `http://example.org:80/` → `http://example.org/` + +- `UriNormalizer::REMOVE_DOT_SEGMENTS` + + Removes unnecessary dot-segments. Dot-segments in relative-path references are not removed as it would + change the semantics of the URI reference. + + Example: `http://example.org/../a/b/../c/./d.html` → `http://example.org/a/c/d.html` + +- `UriNormalizer::REMOVE_DUPLICATE_SLASHES` + + Paths which include two or more adjacent slashes are converted to one. Webservers usually ignore duplicate slashes + and treat those URIs equivalent. But in theory those URIs do not need to be equivalent. So this normalization + may change the semantics. Encoded slashes (%2F) are not removed. + + Example: `http://example.org//foo///bar.html` → `http://example.org/foo/bar.html` + +- `UriNormalizer::SORT_QUERY_PARAMETERS` + + Sort query parameters with their values in alphabetical order. However, the order of parameters in a URI may be + significant (this is not defined by the standard). So this normalization is not safe and may change the semantics + of the URI. + + Example: `?lang=en&article=fred` → `?article=fred&lang=en` + +### `GuzzleHttp\Psr7\UriNormalizer::isEquivalent` + +`public static function isEquivalent(UriInterface $uri1, UriInterface $uri2, $normalizations = self::PRESERVING_NORMALIZATIONS): bool` + +Whether two URIs can be considered equivalent. Both URIs are normalized automatically before comparison with the given +`$normalizations` bitmask. The method also accepts relative URI references and returns true when they are equivalent. +This of course assumes they will be resolved against the same base URI. If this is not the case, determination of +equivalence or difference of relative references does not mean anything. diff --git a/vendor/guzzlehttp/psr7/composer.json b/vendor/guzzlehttp/psr7/composer.json new file mode 100644 index 00000000..58dcb07e --- /dev/null +++ b/vendor/guzzlehttp/psr7/composer.json @@ -0,0 +1,49 @@ +{ + "name": "guzzlehttp/psr7", + "type": "library", + "description": "PSR-7 message implementation that also provides common utility methods", + "keywords": ["request", "response", "message", "stream", "http", "uri", "url", "psr-7"], + "license": "MIT", + "authors": [ + { + "name": "Michael Dowling", + "email": "mtdowling@gmail.com", + "homepage": "https://github.com/mtdowling" + }, + { + "name": "Tobias Schultze", + "homepage": "https://github.com/Tobion" + } + ], + "require": { + "php": ">=5.4.0", + "psr/http-message": "~1.0", + "ralouphie/getallheaders": "^2.0.5 || ^3.0.0" + }, + "require-dev": { + "phpunit/phpunit": "~4.8.36 || ^5.7.27 || ^6.5.14 || ^7.5.20 || ^8.5.8 || ^9.3.10", + "ext-zlib": "*" + }, + "provide": { + "psr/http-message-implementation": "1.0" + }, + "suggest": { + "laminas/laminas-httphandlerrunner": "Emit PSR-7 responses" + }, + "autoload": { + "psr-4": { + "GuzzleHttp\\Psr7\\": "src/" + }, + "files": ["src/functions_include.php"] + }, + "autoload-dev": { + "psr-4": { + "GuzzleHttp\\Tests\\Psr7\\": "tests/" + } + }, + "extra": { + "branch-alias": { + "dev-master": "1.7-dev" + } + } +} diff --git a/vendor/guzzlehttp/psr7/src/AppendStream.php b/vendor/guzzlehttp/psr7/src/AppendStream.php new file mode 100644 index 00000000..fa9153d7 --- /dev/null +++ b/vendor/guzzlehttp/psr7/src/AppendStream.php @@ -0,0 +1,246 @@ +addStream($stream); + } + } + + public function __toString() + { + try { + $this->rewind(); + return $this->getContents(); + } catch (\Exception $e) { + return ''; + } + } + + /** + * Add a stream to the AppendStream + * + * @param StreamInterface $stream Stream to append.

Only PHPAmqpLib uses it if provided. + +#### RotatingFileHandler + +- The file name format must now contain `{date}` and the date format must be set + to one of the predefined FILE_PER_* constants to avoid issues with file rotation. + See `setFilenameFormat`. + +#### LogstashFormatter + +- Removed Logstash V0 support +- Context/extra prefix has been removed in favor of letting users configure the

Although an individual modular reduction takes more time + * then an individual division, when performed in succession (with the same modulo), they're a lot faster. + * + * The two most commonly used modular reductions are Barrett and Montgomery reduction. Montgomery reduction, + * although faster, only works when the gcd of the modulo and of the base being used is 1. In RSA, when the + * base is a power of two, the modulo - a product of two primes - is always going to have a gcd of 1 (because + * the product of two odd numbers is odd), but what about when RSA isn't used? + * + * In contrast, Barrett reduction has no such constraint. As such, some bigint implementations perform a + * Barrett reduction after every operation in the modpow function.

Input these values either in `WP Admin > Settings > WP Google Login`, or in `wp-config.php` using the following code snippet: - -```php -define( 'WP_GOOGLE_LOGIN_CLIENT_ID', 'YOUR_GOOGLE_CLIENT_ID' ); -define( 'WP_GOOGLE_LOGIN_SECRET', 'YOUR_SECRET_KEY' ); -``` - -### How to enable automatic user registration? - -You can enable user registration either by -- Checking `Settings > WP Google Login > Enable Google Login Registration` -OR -- Adding `define( 'WP_GOOGLE_LOGIN_USER_REGISTRATION', 'true' );` in wp-config.php file. - -Note: If the checkbox is ON then, it will register valid Google users even when WordPress default setting, under `Settings > General Settings > Membership > Anyone can register` checkbox is OFF. - -### How to restrict user registration to one or more domain(s)? - -By default, when you enable user registration via constant `WP_GOOGLE_LOGIN_USER_REGISTRATION` or enable `Settings > WP Google Login > Enable Google Login Registration`, it will create a user for any Google login (including gmail.com users). If you are planning to use this plugin on a private, internal site, then you may like to restrict user registration to users under a single Google Suite organization. This configuration variable does that. - -Add your domain name, without any schema prefix and `www,` as the value of `WP_GOOGLE_LOGIN_WHITELIST_DOMAINS` constant or in the settings `Settings > WP Google Login > Whitelisted Domains`. You can whitelist multiple domains. Please separate domains with commas. See the below example to know how to do it via constants: - -```php -define( 'WP_GOOGLE_LOGIN_WHITELIST_DOMAINS', 'example.com,sample.com' ); +# Login with Github + +> WordPress plugin to login/register with github + +1. [Overview](#overview) +2. [Installation](#installation) +3. [Usage Instructions](#usage-instructions) +4. [Shortcode](#shortcode) +5. [Minimum Requirements](#minimum-requirements) +6. [License](#license) + +## Overview + +Login with github provides seamless experience for users to login in to WordPress +sites using their github account. No need to manually create accounts, no need to remember quirky +passwords. Just one click and land into the site! + +## Installation + +1. Clone this repository. +2. Run `composer install --no-dev` from inside the cloned directory. +3. Upload the directory to `wp-content/plugins` directory. +4. Activate the plugin from WordPress dashboard. + +## Usage Instructions + +1. You will need to register a new application at https://github.com/settings/applications/new + +2. `Authorization callback URL` should be like `https://yourdomain.com/wp-login.php`, where +`https://yourdomain.com` will be replaced by your site URL. + +3. Once you create the app, you will receive the `Client ID` and `Client Secret`, add these credentials +in `Settings > Login with github` settings page in their respective fields. + +4. `Create new user` enables new user registration irrespective of `Membership` settings in + `Settings > General`; as sometimes enabling user registration can lead to lots of spam users. + Plugin will take this setting as first priority and membership setting as second priority, so if + any one of them is enabled, new users will be registered by this plugin after successful authorization. + +5. `Whitelisted Domains` allows users from specific domains (domain in email) to get registered on site. +This will prevent unwanted registration on website. +**For Example:** If you want users only from your organization (`myorg.com`) to get registered on the +website, you enter `myorg.com` in whitelisted domains. Users with github primary +email like `abc@myorg.com` will be able to register on website. Contrary to this, users with emails like +`something@gmail.com` would not be able to register here. + +## Shortcode + +You can add the github login button to any page/post using shortcode: `gh_login` + +**Example:** +```php +[gh_login button_text="Github Login" force_display="yes" /] ``` -**Note:** If a user already exists, they **will be allowed to login with Google** regardless of whether their domain is whitelisted or not. Whitelisting will only prevent users from **registering** with email addresses from non-whitelisted domains. - - -## Hooks - -### 1. Action `wp_google_login_token` - -This action provides access token received after Google login. -**Parameters:** -* `token` (Array): Converted token using `fetchAccessTokenWithAuthCode` method of `Google_Client` class. -* `user_info` (Array): Details of user after login. -* `client` (Object): `Google_Client` object in use. - -### 2. Filter `wp_google_login_scopes` - -This filter can be used to filter existing scope used in Google Sign in. -You can ask for additional permission while user logs in. - -This filter will provide 1 parameter `scopes` in callback, which contains array of scopes. - - -## wp-config.php parameters list - -| | Type | Description | -|-----------------------------------|---------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------| -| WP_GOOGLE_LOGIN_CLIENT_ID | String | Google client ID of your application. | -| WP_GOOGLE_LOGIN_SECRET | String | Secret key of your application | -| WP_GOOGLE_LOGIN_USER_REGISTRATION | Boolean | (Optional) Set True If you want to enable new user registration. By default, user registration defers to `Settings > General Settings > Membership` if constant is not set. | -| WP_GOOGLE_LOGIN_WHITELIST_DOMAINS | String | (Optional) Domain name, if you want to restrict login with your custom domain. By default, It will allow all domains. You can whitelist multiple domains. | - - -## Contribute - -### Reporting a bug 🐞 - -Before creating a new issue, do browse through the [existing issues](https://github.com/rtCamp/login-with-google/issues) for resolution or upcoming fixes. - -If you still need to [log an issue](https://github.com/rtCamp/login-with-google/issues/new), making sure to include as much detail as you can, including clear steps to reproduce your issue if possible. - -### Creating a pull request - -Want to contribute a new feature?
