> Angularfire2 应该是这样的：

 构造函数（public af：AngularFire）{
 this。 af.auth.subscribe（auth => {
 //这里你得到用户信息
 console.log（auth））; $ {
} 
} 
 login（）{
 this.af.auth.login（{
 provider：AuthProviders.Facebook，
 method：AuthMethods.Popup ，
}）; 

 $ / code>

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,
    });
  }
