Components

The zswag repository contains two main libraries which provide OpenAPI layers for zserio Python and C++ clients. For Python, there is even a generic zserio OpenAPI server layer.

The following UML diagram provides a more in-depth overview:

Here are some brief descriptions of the main components:

zswagcl is a C++ Library which exposes the zserio OpenAPI service client OAClient as well as the more generic OpenApiClient and OpenApiConfig classes. The latter two are reused for the Python client library.
zswag is a Python Library which provides both a zserio Python service client (OAClient) as well as a zserio-OpenAPI server layer based on Flask/Connexion (OAServer). It also contains the command-line tool zswag.gen, which can be used to generate an OpenAPI specification from a zserio Python service class.
pyzswagcl is a binding library which exposes the C++-based OpenApi parsing/request functionality to Python. Please consider it "internal".
httpcl is a wrapper around cpp-httplib, HTTP request configuration and OS secret storage abilities based on the keychain library.

Setup

For Python Users

Simply run pip install zswag. Note: This only works with ...

64-bit Python 3.8.x, pip --version >= 19.3
64-bit Python 3.9.x, pip --version >= 19.3

Note: On Windows, make sure that you have the Microsoft Visual C++ Redistributable Binaries installed. You can find the x64 installer here: https://aka.ms/vs/16/release/vc_redist.x64.exe

For C++ Users

Using CMake, you can ...

🌟run tests.
🌟build the zswag wheels for a custom Python version.
🌟integrate the C++ client into a C++ project.

Dependencies are managed via CMake's FetchContent mechanism and Conan 2.0. Make sure you have a recent version of CMake (>= 3.24) and Conan (>= 2.0.5) installed.

The basic setup follows the usual CMake configure/build steps:

mkdir build && cd build
cmake ..
cmake --build .

Note: The Python environment used for configuration will be used to build the resulting wheels. After building, you will find the Python wheels under build/bin/wheel.

To run tests, just execute CTest at the top of the build directory:

cd build && ctest --verbose

OpenAPI Generator CLI

After installing zswag via pip as described above, you can run python -m zswag.gen, a CLI to generate OpenAPI YAML files. The CLI offers the following options

usage: Zserio OpenApi YAML Generator [-h] -s service-identifier -i
                                     zserio-or-python-path
                                     [-r zserio-src-root-dir]
                                     [-p top-level-package] [-c tags [tags ...]]
                                     [-o output] [-b BASE_CONFIG_YAML]

optional arguments:
  -h, --help
        show this help message and exit
  -s service-identifier, --service service-identifier

        Fully qualified zserio service identifier.

        Example:
            -s my.package.ServiceClass

  -i zserio-or-python-path, --input zserio-or-python-path

        Can be either ...
        (A) Path to a zserio .zs file. Must be either a top-
            level entrypoint (e.g. all.zs), or a subpackage
            (e.g. services/myservice.zs) in conjunction with
            a "--zserio-source-root|-r <dir>" argument.
        (B) Path to parent dir of a zserio Python package.

        Examples:
            -i path/to/schema/main.zs         (A)
            -i path/to/python/package/parent  (B)

  -r zserio-src-root-dir, --zserio-source-root zserio-src-root-dir

        When -i specifies a zs file (Option A), indicate the
        directory for the zserio -src directory argument. If
        not specified, the parent directory of the zs file
        will be used.

  -p top-level-package, --package top-level-package

        When -i specifies a zs file (Option A), indicate
        that a specific top-level zserio package name
        should be used.

        Examples:
            -p zserio_pkg_name

  -c tags [tags ...], --config tags [tags ...]

        Configuration tags for a specific or all methods.
        The argument syntax follows this pattern:

           [(service-method-name):](comma-separated-tags)

        Note: The -c argument may be applied multiple times.
        The `comma-separated-tags` must be a list of tags
        which indicate OpenApi method generator preferences.
        The following tags are supported:

        get|put|post|delete : HTTP method tags
                query|path| : Parameter location tags
                header|body
                  flat|blob : Flatten request object,
                              or pass it as whole blob.
          (param-specifier) : Specify parameter name, format
                              and location for a specific
                              request-part. See below.
            security=(name) : Set a particular security
                              scheme to be used. The scheme
                              details must be provided through
                              the --base-config-yaml.
         path=(method-path) : Set a particular method path.
                              May contain placeholders for
                              path params.

        A (param-specifier) tag has the following schema:

            (field?name=...
                  &in=[path|body|query|header]
                  &format=[binary|base64|hex]
                  [&style=...]
                  [&explode=...])

        Examples:

          Expose all methods as POST, but `getLayerByTileId`
          as GET with flat path-parameters:

            `-c post getLayerByTileId:get,flat,path`

          For myMethod, put the whole request blob into the a
          query "data" parameter as base64:

            `-c myMethod:*?name=data&in=query&format=base64`

          For myMethod, set the "AwesomeAuth" auth scheme:

            `-c myMethod:security=AwesomeAuth`

          For myMethod, provide the path and place myField
          explicitely in a path placeholder:

            `-c 'myMethod:path=/my-method/{param},...
                 myField?name=param&in=path&format=string'`

        Note:
            * The HTTP-method defaults to `post`.
            * The parameter 'in' defaults to `query` for
              `get`, `body` otherwise.
            * If a method uses a parameter specifier, the
              `flat`, `body`, `query`, `path`, `header` and
              `body`-tags are ignored.
            * The `flat` tag is only meaningful in conjunction
              with `query` or `path`.
            * An unspecific tag list (no service-method-name)
              affects the defaults only for following, not
              preceding specialized tag assignments.

  -o output, --output output

        Output file path. If not specified, the output will be
        written to stdout.

  -b BASE_CONFIG_YAML, --base-config-yaml BASE_CONFIG_YAML

        Base configuration file. Can be used to fully or partially
        substitute --config arguments, and to provide additional
        OpenAPI information. The YAML file must look like this:

          method: # Optional method tags dictionary
            <method-name|*>: <list of config tags>
          securitySchemes: ... # Optional OpenAPI securitySchemes
          info: ...            # Optional OpenAPI info section
          servers: ...         # Optional OpenAPI servers section
          security: ...        # Optional OpenAPI global security

Generator Usage example

Let's consider the following zserio service saved under myapp/services.zs:

package services;

struct Request {
  int32 value;
};

struct Response {
  int32 value;
};

service MyService {
  Response myApi(Request);
};

An OpenAPI file api.yaml for MyService can now be created with the following zswag.gen invocation:

cd myapp
python -m zswag.gen -s services.MyService -i services.zs -o api.yaml

You can further customize the generation using -c configuration arguments. For example, -c get,flat,path will recursively "flatten" the zserio request object into it's compound scalar fields using x-zserio-request-part for all methods. If you want to change OpenAPI parameters only for one particular method, you can prefix the tag config argument with the method name (-c methodName:tags...).

Documentation Extraction

When invoking zswag.gen with -i zserio-file an attempt will be made to populate the service/method/request/response descriptions with doc-strings that are extracted from the zserio sources.

For structs and services, the documentation is expected to be enclosed by /*! .... !*/ markers preceding the declaration:

/*!
### My Markdown Struct Doc
I choose to __highlight__ this word.
!*/

struct MyStruct {
    ...
};

For service methods, a single-line doc-string is parsed which immediately precedes the declaration:

/** This method is documented. */
ReturnType myMethod(ArgumentType);

Server Component

The OAServer component gives you the power to marry a zserio-generated app server class with a user-written app controller and a fitting OpenAPI specification. It is based on Flask and Connexion.

Implementation choice regarding HTTP response codes: The server as implemented here will return HTTP code 400 (Bad Request) when the user request could not be parsed, and 500 (Internal Server Error) when a different exception occurred while generating the response/running the user's controller implementation.

Integration Example

We consider the same myapp directory with a services.zs zserio file as already used in the OpenAPI Generator Example.

Note:

myapp must be available as a module (it must be possible to import myapp).
We recommend to run the zserio Python generator invocation inside the myapp module's __init__.py, like this:

import zserio
from os.path import dirname, abspath

working_dir = dirname(abspath(__file__))
zserio.generate(
  zs_dir=working_dir,
  main_zs_file="services.zs",
  gen_dir=working_dir)

A server script like myapp/server.py might then look as follows:

import zswag
import myapp.controller as controller
from myapp import working_dir

# This import only works after zserio generation.
import services.api as services

app = zswag.OAServer(
  controller_module=controller,
  service_type=services.MyService.Service,
  yaml_path=working_dir+"/api.yaml",
  zs_pkg_path=working_dir)

if __name__ == "__main__":
    app.run()

The server script above references two important components:

An OpenAPI file (myapp/api.yaml): Upon startup, OAServer will output an error message if this file does not exist. The error message already contains the correct command to invoke the OpenAPI Generator CLI to generate myapp/api.yaml.
A controller module (myapp/controller.py): This file provides the actual implementations for your service endpoints.

For the current example, controller.py might look as follows:

import services.api as services

# Written by you
def my_api(request: services.Request):
    return services.Response(request.value * 42)

Using the Python Client

The generic Python client talks to any zserio service that is running via HTTP/REST, and provides an OpenAPI specification of it's interface.

Integration Example

As an example, consider a Python module called myapp which has the same myapp/__init__.py and myapp/services.zs zserio definition as previously mentioned. We consider that the server is providing its OpenAPI spec under localhost:5000/openapi.json.

In this setting, a client myapp/client.py might look as follows:

from zswag import OAClient
import services.api as services

openapi_url = "http://localhost:5000/openapi.json"

# The client reads per-method HTTP details from the OpenAPI URL.
# You can also pass a local file by setting the `is_local_file` argument
# of the OAClient constructor.
client = services.MyService.Client(OAClient(openapi_url))

# This will trigger an HTTP request under the hood.
client.my_api(services.Request(1))

As you can see, an instance of OAClient is passed into the constructor for zserio to use as the service client's transport implementation.

Note: While connecting, the client will also use ...

Persistent HTTP configuration.

Additional HTTP query/header/cookie/proxy/basic-auth configs passed into the OAClient constructor using an instance of zswag.HTTPConfig. For example:

from zswag import OAClient, HTTPConfig
import services.api as services
config = HTTPConfig() \
    .header(key="X-My-Header", val="value") \  # Can be specified 
    .cookie(key="MyCookie", val="value")    \  # multiple times.
    .query(key="MyCookie", val="value")     \  # 
    .proxy(host="localhost", port=5050, user="john", pw="doe") \
    .basic_auth(user="john", pw="doe") \
    .bearer("bearer-token") \
    .api_key("token")

client = services.MyService.Client(
    OAClient("http://localhost:8080/openapi.", config=config))

# Alternative when specifying api-key or bearer
client = services.MyService.Client(
    OAClient("http://localhost:8080/openapi.", api_key="token", bearer="token"))

Note: The additional config will only enrich, not overwrite the default persistent configuration. If you would like to prevent persistent config from being considered at all, set HTTP_SETTINGS_FILE to empty, e.g. via os.environ['HTTP_SETTINGS_FILE']=''

C++ Client

The generic C++ client talks to any zserio service that is running via HTTP/REST, and provides an OpenAPI specification of its interface. When using the C++ OAClient with your zserio schema, make sure that the flags -withTypeInfoCode and -withReflectionCode are passed to the zserio C++ emitter.

Integration Example

As an example, we consider the myapp directory which contains a services.zs zserio definition as previously mentioned.

We assume that zswag is added to myapp as a Git submodule under myapp/zswag.

Next to myapp/services.zs, we place a myapp/CMakeLists.txt which describes our project:

project(myapp)

# If you are not interested in building zswag Python
# wheels, you can set the following option:
# set(ZSWAG_BUILD_WHEELS OFF)

# If your compilation environment does not provide
# libsecret, the following switch will disable keychain integration:
# set(ZSWAG_KEYCHAIN_SUPPORT OFF)

# In case you want to build zswag without using conan
# make sure to provide targets for OpenSSL and spdlog
# and set the following switch to OFF:
# set(ZSWAG_WITH_CONAN OFF)

# This is how C++ will know about the zswag lib
# and its dependencies, such as zserio.
if (NOT TARGET zswag)
        FetchContent_Declare(zswag
                GIT_REPOSITORY "https://github.com/ndsev/zswag.git"
                GIT_TAG        "v1.6.7"
                GIT_SHALLOW    ON)
        FetchContent_MakeAvailable(zswag)
endif()

find_package(OpenSSL CONFIG REQUIRED)
target_link_libraries(httplib INTERFACE OpenSSL::SSL)

# This command is provided by zswag to easily create
# a CMake C++ reflection library from zserio code.
add_zserio_library(${PROJECT_NAME}-zserio-cpp
  WITH_REFLECTION
  ROOT "${CMAKE_CURRENT_SOURCE_DIR}"
  ENTRY services.zs
  TOP_LEVEL_PKG myapp_services)

# We create a myapp client executable which links to
# the generated zserio C++ library and the zswag client
# library.
add_executable(${PROJECT_NAME} client.cpp)

# Make sure to link to the `zswagcl` target
target_link_libraries(${PROJECT_NAME}
    ${PROJECT_NAME}-zserio-cpp zswagcl)

Note: OpenSSL is assumed to be installed or built using the lib (not lib64) directory name.

The add_executable command above references the file myapp/client.cpp, which contains the code to actually use the zswag C++ client.

#include "zswagcl/oaclient.hpp"
#include <iostream>
#include "myapp_services/services/MyService.h"

using namespace zswagcl;
using namespace httpcl;
namespace MyService = myapp_services::services::MyService;

int main (int argc, char* argv[])
{
    // Assume that the server provides its OpenAPI definition here
    auto openApiUrl = "http://localhost:5000/openapi.json";
    
    // Create an HTTP client to be used by our OpenAPI client
    auto httpClient = std::make_unique<HttpLibHttpClient>();
    
    // Fetch the OpenAPI configuration using the HTTP client
    auto openApiConfig = fetchOpenAPIConfig(openApiUrl, *httpClient);
    
    // Create a Zserio reflection-based OpenAPI client that
    // uses the OpenAPI configuration we just retrieved.
    auto openApiClient = OAClient(openApiConfig, std::move(httpClient));
        
    // Create a MyService client based on the OpenApi-Client
    // implementation of the zserio::IServiceClient interface.
    auto myServiceClient = MyService::Client(openApiClient);
    
    // Create the request object
    auto request = myapp_services::services::Request(2);

    // Invoke the REST endpoint. Mind that your method-
    // name from the schema is appended with a "...Method" suffix.
    auto response = myServiceClient.myApiMethod(request);
    
    // Print the response
    std::cout << "Got " << response.getValue() << std::endl;
}

Note: While connecting, HttpLibHttpClient will also use ...

Persistent HTTP configuration.
Additional HTTP query/header/cookie/proxy/basic-auth configs passed into the OAClient constructor using an instance of httpcl::Config. You can include this class via #include "httpcl/http-settings.hpp". The additional Config will only enrich, not overwrite the default persistent configuration. If you would like to prevent persistent config from being considered at all, set HTTP_SETTINGS_FILE to empty, e.g. via setenv.

Client Environment Settings

Both the Python and C++ Clients can be configured using the following environment variables:

Variable Name	Details
`HTTP_SETTINGS_FILE`	Path to settings file for HTTP proxies and authentication, see next section
`HTTP_LOG_LEVEL`	Verbosity level for console/log output. Set to `debug` for detailed output.
`HTTP_LOG_FILE`	Logfile-path (including filename) to redirect console output. The log will rotate with three files (`HTTP_LOG_FILE`, `HTTP_LOG_FILE-1`, `HTTP_LOG_FILE-2`).
`HTTP_LOG_FILE_MAXSIZE`	Maximum size of the logfile, in bytes. Defaults to 1GB.
`HTTP_TIMEOUT`	Timeout for HTTP requests (connection+transfer) in seconds. Defaults to 60s.
`HTTP_SSL_STRICT`	Set to any nonempty value for strict SSL certificate validation.

Persistent HTTP Headers, Proxy, Cookie and Authentication

Both the Python OAClient and C++ HttpLibHttpClient read a YAML file stored under a path which is given by the HTTP_SETTINGS_FILE environment variable. The YAML file contains a list of HTTP-related configs that are applied to HTTP requests based on a regular expression which is matched against the requested URL.

For example, the following entry would match all requests due to the * url-match-pattern for the scope field:

http-settings:
  # Under http-settings, a list of settings is defined for specific URL scopes.
  - scope: *     # URL scope - e.g. https://*.nds.live/* or *.google.com.
    basic-auth:  # Basic auth credentials for matching requests.
      user: johndoe
      keychain: keychain-service-string
    proxy:      # Proxy settings for matching requests.
      host: localhost
      port: 8888
      user: test
      keychain: ...
    cookies:    # Additional Cookies for matching requests.
      key: value
    headers:    # Additional Headers for matching requests.
      key: value
    query:      # Additional Query parameters for matching requests.
      key: value
    api-key: value  # API Key as required by OpenAPI config - see description below.

Note: For proxy configs, the credentials are optional.

The api-key setting will be applied under the correct cookie/header/query parameter, if the service you are connecting to uses an OpenAPI apiKey auth scheme.

Passwords can be stored in clear text by setting a password field instead of the keychain field. Keychain entries can be made with different tools on each platform:

Client Result Code Handling

Both clients (Python and C++) will treat any HTTP response code other than 200 as an error since zserio services are expected to return a parsable response object. The client will throw an exception with a descriptive message if the response code is not 200.

In case applications want to utilize for example the 204 (No Content) response code, they have to catch the exception and handle it accordingly.

Swagger User Interface

If you have installed pip install "connexion[swagger-ui]", you can view API docs of your service under [/prefix]/ui.

OpenAPI Options Interoperability

The Server, Clients and Generator offer various degrees of freedom regarding the OpenAPI YAML file. The following sections detail which components support which aspects of OpenAPI. The difference in compliance is mostly due to limited development scopes. If you are missing a particular OpenAPI feature for a particular component, feel free to create an issue!

Note: For all options that are not supported by zswag.gen, you will need to manually edit the OpenAPI YAML file to achieve the desired configuration. You will also need to edit the file manually to fill in meta-info (provider name, service version, etc.).

HTTP method

To change the HTTP method, the desired method name is placed as the key under the method path, such as in the following example:

paths:
  /methodName:
    {get|post|put|delete}:
      ...

Component Support

Feature	C++ Client	Python Client	OAServer	zswag.gen
`get` `post` `put` `delete`	✔️	✔️	✔️	✔️
`patch`	❌️	❌️	❌️	❌️

Note: Patch is unsupported, because the required semantics of a partial object update cannot be realized in the zserio transport layer interface.

Request Body

A server can instruct clients to transmit their zserio request object in the request body when using HTTP post, put or delete. This is done by setting the OpenAPI requestBody/content to application/x-zserio-object:

requestBody:
  content:
    application/x-zserio-object:
      schema:
        type: string

Component Support

Feature	C++ Client	Python Client	OAServer	zswag.gen
`application/x-zserio-object`	✔️	✔️	✔️	✔️

URL Blob Parameter

Zswag tools support an additional OpenAPI method parameter field called x-zserio-request-part. Through this field, a service provider can express that a certain request parameter only contains a part of, or the whole zserio request object. When parameter contains the whole request object, x-zserio-request-part should be set to an asterisk (*):

parameters:
- description: ''
  in: query|path|header
  name: parameterName
  required: true
  x-zserio-request-part: "*"
  schema:
    format: string|byte|base64|base64url|hex|binary

About the format specifier value:

Both string and binary result in a raw URL-encoded string buffer.
Both byte and base64 result in a standard Base64-encoded value. The base64url option indicates URL-safe Base64 format.
The hex encoding produces a hexadecimal encoding of the request blob.

Note: When a parameter is passed with in=path, its value must not be empty. This holds true for strings and bytes, but also for arrays (see below).

Component Support

Feature	C++ Client	Python Client	OAServer	zswag.gen
`x-zserio-request-part: *`	✔️	✔️	✔️	✔️
`format: string`	✔️	✔️	✔️	✔️
`format: byte`	✔️	✔️	✔️	✔️
`format: hex`	✔️	✔️	✔️	✔️

URL Scalar Parameter

Using x-zserio-request-part, it is also possible to transfer only a single scalar (nested) member of the request object:

parameters:
- description: ''
  in: query|path|header
  name: parameterName
  required: true
  x-zserio-request-part: "[parent.]*member"
  schema:
    format: string|byte|base64|base64url|hex|binary

In this case, x-zserio-request-part should point to a scalar type, such as uint8, float32, string etc.

The format value effect remains as explained above. A small difference exists for integer types: Their hexadecimal representation will be the natural numeric one, not binary.

Component Support

Feature	C++ Client	Python Client	OAServer	zswag.gen
`x-zserio-request-part: <[parent.]*member>`	✔️	✔️	✔️	✔️

URL Array Parameter

The x-zserio-request-part may also point to an array member of the zserio request struct, like so:

parameters:
- description: ''
  in: query|path|header
  style: form|simple|label|matrix
  explode: true|false
  name: parameterName
  required: true
  x-zserio-request-part: "[parent.]*array_member"
  schema:
    format: string|byte|base64|base64url|hex|binary

In this case, x-zserio-request-part should point to an array of scalar types. The array will be encoded according to the format, style and explode specifiers.

Feature	C++ Client	Python Client	OAServer	zswag.gen
`x-zserio-request-part: <[parent.]*array_member>`	✔️	✔️	✔️	✔️
`style: simple`	✔️	✔️	✔️	✔️
`style: form`	✔️	✔️	✔️	✔️
`style: label`	✔️	✔️	❌	✔️
`style: matrix`	✔️	✔️	❌	✔️
`explode: true`	✔️	✔️	✔️	✔️

URL Compound Parameter

In this case, x-zserio-request-part points to a zserio compound struct instead of a field with a scalar value. This is currently not supported.

Server URL Base Path

OpenAPI allows for a servers field in the spec that lists URL path prefixes under which the specified API may be reached. The OpenAPI clients looks into this list to determine a URL base path from the first entry in this list. A sample entry might look as follows:

servers:
- http://unused-host-information/path/to/my/api

The OpenAPI client will then call methods with your specified host and port, but prefix the /path/to/my/api string.

Authentication Schemes

To facilitate the communication of authentication needs for the whole or parts of a service, OpenAPI allows for securitySchemes and security fields in the spec. Please refer to the relevant parts of the OpenAPI 3 specification for some examples on how to integrate these fields into your spec.

Zswag currently understands the following authentication schemes:

HTTP Basic Authorization: If a called endpoint requires HTTP basic auth, zswag will verify that the HTTP config contains basic-auth credentials. If there are none, zswag will throw a descriptive runtime error.
HTTP Bearer Authorization: If a called endpoint requires HTTP bearer auth, zswag will verify that the HTTP config contains a header with the key name Authorization and the value Bearer <token>, case-sensitive.
API-Key Cookie: If a called endpoint requires a Cookie API-Key, zswag will either apply the api-key setting, or verify that the HTTP config contains a cookie with the required name, case-sensitive.
API-Key Query Parameter: If a called endpoint requires a Query API-Key, zswag will either apply the api-key setting, or verify that the HTTP config contains a query key-value pair with the required name, case-sensitive.
API-Key Header: If a called endpoint requires an API-Key Header, zswag will either apply the api-key setting, or verify that the HTTP config contains a header key-value pair with the required name, case-sensitive.

Note: If you don't want to pass your Basic-Auth/Bearer/Query/Cookie/Header credential through your persistent config, you can pass a httpcl::Config/HTTPConfig object to the OAClient/OAClient. constructor in C++/Python with the relevant detail.

(**): The server support for all authentication schemes depends on your configuration of the WSGI server (Apache/Nginx/...) which wraps the zswag Flask app.
