Encoding attributes

The writeToken method of the Agent class takes a java.util.Map collection of attributes and encodes them into an OpenToken, which is then written to the HTTP response.

The collection of attributes must contain a key named subject for a valid token to be generated.

If any errors are encountered while creating the token or writing the token out to the response, a TokenException is thrown.

The following example code shows how to use the writeToken method:

This code is the same for both the Java native and Apache commons multimap methods described in Reading and writing OpenTokens.

Sample code

String username = (String)request.getSession().getAttribute("username");
Map<String, String> userInfo = new HashMap<String, String>();
userInfo.put(Agent.TOKEN_SUBJECT, username);
String returnUrl = "https://<PingFederate-DNS>:9031" + request.getParameter("resume");
. . . .
try {
   UrlHelper urlHelper = new UrlHelper(returnUrl);
   //See the "Reading and writing OpenTokens" topic for sample code
   //that instantiates and configures an Agent instance
   agent.writeToken(userInfo,response,urlHelper,false);
   returnUrl = (String)urlHelper.toString();
}
catch(TokenException e) {
// Handle exception
}
