meteor login with facebook

client.js

/* Imagine you want to develop a facebook canvas app.
   This snippet will do all the auth dance without requiring the user to click on login.
   But if the user is not logged in facebook, it will ask for the user to login.
   Tip: Open the browser console to see debug messages.
   Followed instructions of Facebook: https://developers.facebook.com/docs/howtos/login/getting-started/
   It's is possible to improve this code with more error handling.

                    if (!error){

                    }
                }, {scope: 'email,friends_likes,friends_birthday'});
            }
        }
    }
}

server.js

if (Meteor.is_server) {
    Meteor.methods({
        facebook_login: function(fbUser, accessToken) {
            var options, serviceData, userId;
            serviceData = {
              id: fbUser.id,
              accessToken: accessToken,
              email: fbUser.email
            };
            options = {
              profile: {
                name: fbUser.name
              }
            };
            return userId = Accounts.updateOrCreateUserFromExternalService('facebook', serviceData, options).id;
        }
   });
}

On client.js line 35 do the following instead, using the 'facebook' branch on Github:

var state = Random.id();
Meteor.http.get('/_oauth/facebook', {
  params: {
    state: state,
    access_token: access_token
  }
}, function() {
   Meteor.apply('login', [{oauth: {state: state}}], {wait: true}, function(e, result) {
      Accounts._makeClientLoggedIn(result.id, result.token);   
   });
})

Well, that didn't work. I will wait for you to come back from vacation :)

Does anyone have solution on this? @gabrielhpugliese did you manage to login user automatically?
