Access scope data after Firebase authentication

问题:

I authorized the calendar api in my google sign in auth, using the following code (Angularfire2):

let auth = new firebase.auth.GoogleAuthProvider();
    auth.addScope('https://www.googleapis.com/auth/calendar');
    this.afAuth.auth
      .signInWithPopup(auth).then((data) => {
        console.log(data); // nothing about calendar here
      });

Is there any way to access authorized scopes using FirebaseAuth?

For example, access the calendar data after the user signs and authorizes the calendar auth.

If you check out the reference docs, you'll see that there are examples for each provider, which demonstrate how to obtain the third-party OAuth token:

// Using a redirect.
firebase.auth().getRedirectResult().then(function(result) {
  if (result.credential) {
    // This gives you a Google Access Token.
    var token = result.credential.accessToken;
  }
  var user = result.user;
});

Once you have the third-party token, you can use that directly against their APIs.
