Angular2身份验证卡导航至主页

我是angular 2的新手，当我刷新它的重定向到登录页面时，实际上我遇到了一个问题，但实际上我想重定向到仪表板

canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean> | boolean {
    // get observable
    const observable = this.store.select(isAuthenticated);
        // redirect to sign in page if user is not authenticated
    observable.subscribe(authenticated => {
      if (!authenticated) {
        this.router.navigate(['/login']);
      }
    });

    return observable;

  }

请详细说明你的问题。无法正确识别您的问题，但根据我的理解，您可以将guard写为

canActivate(
next: ActivatedRouteSnapshot,
state: RouterStateSnapshot): Observable<boolean> | Promise<boolean> | boolean {
return this.authService.isLoggedIn
  .take(1)
  .map((isLoggedIn: boolean) => {
    console.log(isLoggedIn)
    if (!isLoggedIn) {
      this.router.navigate(['login']);
      return false;
    }
    return true;
  });
}

你可以参考这篇文章来获得详细的解释和说明

canActivate(
next: ActivatedRouteSnapshot,
state: RouterStateSnapshot): Observable<boolean> | Promise<boolean> | boolean {
return this.authService.isLoggedIn
  .take(1)
  .map((isLoggedIn: boolean) => {
    console.log(isLoggedIn)
    if (!isLoggedIn) {
      this.router.navigate(['login']);
      return false;
    }
    return true;
  });
}

 private loggedIn = new BehaviorSubject<boolean>(this.loggedInUser());
 get isLoggedIn() {
     if (localStorage.getItem('userDetails'))
        this.loggedIn.next(true);
     return this.loggedIn.asObservable();
  }
loggedInUser(): boolean {
   return JSON.parse(localStorage.getItem('loggedInUser'));
}

if (!isLoggedIn) {
  this.router.navigate(['login']);
  return false;
}else{
   this.router.navigate(['dashboard']);
   return true;
}
