Question

你能帮帮我吗？我无法在Angularfire身份验证中获取用户的个人资料信息，例如他们的Facebook个人资料图片或Facebook名称。请帮忙。非常感谢！

我已尝试过此代码，但它无效。我使用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.
}

Answer 1

您可以在示例应用部分中看到here，您可以使用auth.subscribe来检测身份验证状态：

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')
        }

    });
  }
}

Answer 2

当您使用 Angularfire2 时，这应该是这样的：

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,
    });
  }
