OAuth 2.0 with WSO2 Playground

Configuring OAuth/OpenID Connect

To use this sample, you first need to configure OAuth/OpenID Connect for a service provider. See Configuring Inbound Authentication for a Service Provider for more information on how to do this.

Configuring the Playground2 web application

To obtain and configure the Playground sample, follow the steps below.

You can check out the repository of the OAuth 2.0 sample from GitHub. Follow the instructions here to checkout the folder. We refer <SAMPLE_HOME> as the modules/samples folder inside the folder where the product-is repository is checked out.
```
https://github.com/wso2/product-is/tree/master/modules/samples/oauth2/playground2
```
In your command line, navigate to <SAMPLE_HOME>/oauth2/playground2 in the folder you checked out and build the sample using the following command. You must have Apache Maven installed to do this (see Installation Prerequisites for the appropriate version to use).
```
mvn clean install
```
After successfully building the sample, a .war file named playground2 can be found inside the <SAMPLE_HOME>/oauth2/playground2/target folder. Deploy this sample web app on a web container. To do this, use the Apache Tomcat server.

Since this sample is written based on Servlet 3.0 it needs to be deployed on Tomcat 7.x.
Use the following steps to deploy the web app in the web container:
1. Stop the Apache Tomcat server if it is already running.
2. Copy the playground2.war file to the <TOMCAT_HOME>/webapps folder.
3. Start the Apache Tomcat server.

Make sure to update param-value the following parameter in the WEB-INF/web.xml file with the server url of the Identity Server if required.
```
<init-param>
     <description>serverUrl</description>
     <param-name>serverUrl</param-name>
     <param-value>https://localhost:9443/services/</param-value>
</init-param>
```
Note that localhost is the server that hosts WSO2 Identity Server and 9443 is the default SSL port of it.

Update param-value of below parameters with credentials of an admin user if required.

<init-param>
     <description>userName</description>
     <param-name>userName</param-name>
     <param-value>admin</param-value>
</init-param>
<init-param>
     <description>password</description>
     <param-name>password</param-name>
     <param-value>admin</param-value>
</init-param>

Restart Apache Tomcat and access http://localhost:8080/playground2.0/ (assuming Tomcat is running on HTTP port 8080). You are directed to the landing page of the sample application. Click on Import Photos and the following page appears.

This application is used to request access tokens using the four OAuth2 grant types.

OAuth 2.0 Grant Types with WSO2 OAuth2 Playground

OAuth 2.0 Authorization code Grant Type with WSO2 OAuth2 Playground

Running the application:

Visit the URL http://localhost:8080/playground2/oauth2.jsp to start the application.
Enter the following details and click Authorize.

Authorization Grant Type: Authorization Code
Client ID: (the client id received at the application registration)
Callback URL: http://localhost:8080/playground/oauth2client

If you have configured the service provider in a tenant, you have to add the tenant domain as a query parameter to the access token endpoint.
If the tenant domain is wso2.com, access token endpoint will be as follows.

Access Token Endpoint: https://localhost:9443/oauth2/token?tenantDomain=wso2.com
At this point the application receives the Access Token.
Click on Get Photos.
Now you should be able to see the user photos.
