Question

如何安装uid 我的.ts文件是这样的，

import { AngularFireAuth } from 'angularfire2/auth';
import * as firebase from 'firebase/app';
import { Router } from "@angular/router";


@Component({
  selector: 'app-candidate-login',
  templateUrl: './candidate-login.component.html',
  styleUrls: ['./candidate-login.component.css']
})
export class CandidateLoginComponent implements OnInit {
user: Observable<firebase.User>;


  constructor(
  public afAuth: AngularFireAuth,
  private router: Router) {

    this.user = afAuth.authState;
   console.log(this.user.uid);

   }

  ngOnInit() {

  }
  login(){
   this.afAuth.auth.signInWithPopup(new firebase.auth.GoogleAuthProvider());
    this.router.navigate(['/registration']);
  }
}

但是它显示了像

这样的错误

C:/MyApp/Join/job-site/src/app/candidate-login/candidate-login.component.ts (23,26): Property 'uid' does not exist on type 'Observable<User>'.

如何解决这个问题？请帮帮我先生？其实我想知道当前的用户？我想安慰它。帮助我吗？

您必须像这样订阅afAuth.authState

this.afAuth.authState.subscribe(user => {
  this.user = user;
  console.log(this.user.uid);
});

不安慰用户的uid？
