Get User Auth Profile Info in Firebase using Angular2

问题

Can you help me? I can't get the user's profile information in Angularfire Authentication like their facebook's profile picture or facebook name. Please help. Thanks a lot!

I've tried this code but its not working. I use Angular 2 TypeScript.

var user = firebase.auth().currentUser;
var name, email, photoUrl, uid;

if (user != null) {
  name = user.displayName;
  email = user.email;
  photoUrl = user.photoURL;
  uid = user.uid;  // The user's ID, unique to the Firebase project. Do NOT use
                   // this value to authenticate with your backend server, if
                   // you have one. Use User.getToken() instead.
}

When you are using Angularfire2 this should be the way:

constructor(public af: AngularFire) {
    this.af.auth.subscribe(auth => {
     //Here you get the user information
     console.log(auth));
    }
  }
  login() {
    this.af.auth.login({
      provider: AuthProviders.Facebook,
      method: AuthMethods.Popup,
    });
  }

As you can see here in the Example app section, you can use auth.subscribe to detect the auth state:

export class myClass {
  constructor(public af: AngularFire) {
    this.af.auth.subscribe(auth => {
        if(auth) {
            console.log('You are authenticated', auth)
        } else {
            console.log('You are not authenticated')
        }

    });
  }
}
