WSO2 OAuth Mediator

WSO2 OAuth mediator can be used for generating OAuth2 tokens for talking to service endpoints secured with OAuth2 protocol in WSO2 ESB/Integrator and API Manager. Currently, it only supports password grant type and client-credentials grant type and it can be extended to incorporate other grant types as required.

Getting Started

1. Clone this project:

   git clone https://github.com/npamudika/wso2-oauth-mediator
   cd wso2-oauth-mediator/
   

2. Build OAuth Mediator using Maven:

   mvn clean install
   

3. Copy OAuth mediator JAR file to the following folder in the WSO2 server:

   [WSO2-SERVER-HOME]/repository/components/lib/
   

4. Create a new configuration file inside the [WSO2-SERVER-HOME]/repository/conf/ folder with the name wso2-oauth-mediator.json with the list of OAuth2 token endpoints required:

   [
     {
       "id": "EP1",
       "tokenApiUrl": "http://localhost:8280/token",
       "apiKey": "1234567890",
       "apiSecret": "0987654321",
       "username": "admin",
       "password": "admin",
       "grantType": "client_credentials",
       "scope": "default",
       "tokenRefreshInterval": 20
     }
   ]

   Note: If you want to use password grant type, change grantType to "password". Note that the token refresh interval is defined in seconds.

5. Create a sequence with the following OAuthMediator and the endpoint id provided in the configuration:

   <sequence xmlns="http://ws.apache.org/ns/synapse" name="oauth-sequence">
       <class name = "org.wso2.apim.mediators.oauth.OAuthMediator">
           <property name="endpointId" value="EP1"></property>
       </class>
   </sequence>

6. Now start the WSO2 server and send a request to the API/proxy endpoint and check the behaviour.
