仅当用户登录角度6时如何显示导航栏

Question

如果用户已登录，我在签入时遇到问题。 导航栏现在的行为是隐藏，因为几分钟后无法获取用户数据。 第一次运行完美，但几分钟后消失。 也许我实现了可观察到的错误。 有人可以帮我吗？ 谢谢！

navbar.component.ts

  export class NavbarComponent implements OnInit {
  loggedUser: Object = {}
  isLogged: boolean = false
  imageUrl: string =  ''
  constructor(private router: RouterModule, private route: Router, private authService: AuthService) {


  }

  ngOnInit() {
    this.imageUrl = env.amazon_images_s3
    const user = AuthService.getUser()
    if(user) {
      this.authService.userLoggedIn$.subscribe(data => { 
        this.isLogged = true
        this.loggedUser = data
      })
    }
  }

 export class AuthService {
      private static CURRENT_USER = 'currentUser'
      private userLoggedIn = new Subject<any>()
      private userLoggedOut = new Subject<any>()
      userLoggedIn$ = this.userLoggedIn.asObservable()
      userLoggedOut$ = this.userLoggedOut.asObservable()
      constructor(private _apiService: ApiService) { }

      public isAuthenticated(): any {
        const user = JSON.parse(localStorage.getItem(AuthService.CURRENT_USER))
        if (user) {
          return user.token.access_token !== null;
        }

        return false
      }

      logIn(username: string, password: string) {
        return this._apiService.post('user/login', { username: username, password: password, auth_type: 'ADMIN' })
          .pipe(map((data) => {
            if (data.token_info) {
              localStorage.setItem(AuthService.CURRENT_USER, JSON.stringify({ "token": data.token_info, "user": data.user }));
              this.userLoggedIn.next(data.user)
            }
            return data;
          }))
      }

我想问题不在于可观察的，因为您最初获得的是结果，而是路线，请尝试使用'==='

 <div class="navbar-menu" *ngIf="route.url === '/map'">
