How can I use socialauth in a rest server?

[Felipe Damiani]

Hey guys, I have a rest application backend and two clients (frontend phonegap and web).

I'd like to know if is it possible to authenticate the user by facebook and gmail account according my arquitechture.

I saw many examples like https://github.com/3pillarlabs/socialauth/wiki/Getting-Started-with-implementing-SocialAuth

But I don't know if it works with rest services and neither how can I do that.

For example, in the link above, has a code as below:

//###### First step

//Create an instance of SocialAuthConfgi object

SocialAuthConfig config = SocialAuthConfig.getDefault();

//load configuration. By default load the configuration from oauth_consumer.properties. 

//You can also pass input stream, properties object or properties file name.

config.load();

//Create an instance of SocialAuthManager and set config

SocialAuthManager manager = new SocialAuthManager();

manager.setSocialAuthConfig(config);

//URL of YOUR application which will be called after authentication

String successUrl = "http://opensource.brickred.com/socialauthdemo/socialAuthSuccessAction.do";

// get Provider URL to which you should redirect for authentication.

// id can have values "facebook", "twitter", "yahoo" etc. or the OpenID URL

String url = manager.getAuthenticationUrl(id, successUrl);

// Store in session

session.setAttribute("authManager", manager);

//#### Second step

// 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.

Map<String, String> paramsMap = SocialAuthUtil.getRequestParametersMap(request); 

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();

As you can see, in the first step I have the code: session.setAttribute("authManager", manager);

and in the second step: SocialAuthManager manager = (SocialAuthManager)session.getAttribute("authManager");

Question: There are another way to do the task above without http sessions?

Any example?

Thanks in advance.
