Question

SocialAuth getting started guide have following code sample:

  // get the auth provider manager from session
  SocialAuthManager manager = (SocialAuthManager)session.getAttribute("authManager");

  // call connect method of manager which returns the provider object. 
  // Pass request parameter map while calling connect method. 
   AuthProvider provider = manager.connect(paramsMap);

  // get profile
  Profile p = provider.getUserProfile();

  // you can obtain profile information
  System.out.println(p.getFirstName());

  // OR also obtain list of contacts
  List<Contact> contactsList = provider.getContactList();

The comment at line 3-4 say that we should pass the request parameter map to manager.connect(). I tried:

manager.connect(request.getParameterMap());

But it gives

java.lang.ClassCastException: [Ljava.lang.String; cannot be cast to java.lang.String

Should I create my own parameter map instead of passing map returned by request.getParameterMap()?

Answering my own question:

The socialauth source have a sample with following code:

Map<String, String> paramsMap = SocialAuthUtil.getRequestParametersMap(request);            
AuthProvider provider = manager.connect(paramsMap);
