Authguard刷新后将我重定向到登录名，这是authguard

package de.tu_chemnitz.dayliehelperprototype;

import.*

/**
 * A BroadcastReceiver that notifies of important wifi p2p events.
 */
public class WiFiDirectBroadcastReceiver extends BroadcastReceiver {

    private WifiP2pManager manager;
    private Channel channel;
    private MainActivity activity;

    private static final String TAG = "WiFiDirectBroadcastReceiver";

    /**
     * @param manager  WifiP2pManager system service
     * @param channel  Wifi p2p channel
     * @param activity activity associated with the receiver
     */
    public WiFiDirectBroadcastReceiver(WifiP2pManager manager, Channel channel,MainActivity activity){
        super();
        this.manager = manager;
        this.channel = channel;
        this.activity = activity;
    }

    /*
     * (non-Javadoc)
     * @see android.content.BroadcastReceiver#onReceive(android.content.Context,
     * android.content.Intent)
     */
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION.equals(action)) {

            // UI update to indicate wifi p2p status.
            int state = intent.getIntExtra(WifiP2pManager.EXTRA_WIFI_STATE, -1);
            if (state == WifiP2pManager.WIFI_P2P_STATE_ENABLED && Utility.getBool(activity, "switch_states", "notify_switchkey")) {
                activity.startFindPeers();
            }
            else {

            }
            Log.d(TAG, "P2P state changed - " + state);
        }
        else if (WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION.equals(action)) {

            // request available peers from the wifi p2p manager. This is an
            // asynchronous call and the calling activity is notified with a
            // callback on PeerListListener.onPeersAvailable()
            if (manager != null) {
                manager.requestPeers(channel, activity.peerListListener);
            }
            Log.d(TAG, "P2P peers changed");
        }
        else if (WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION.equals(action)) {

        }
        else if (WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION.equals(action)) {

        }
    }
}

这是身份验证服务

constructor(private auth: AuthService,
    private router: Router) {
  }
  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot): Observable<boolean> | Promise<boolean> | boolean {
    if (this.auth.isLoggedIn === true) {
      return true;
    } else {
      this.router.navigate(['login']);
      return false;
    }
  }

login.ts

  private loggedInStatus = false;
      setLoggedIn(value: boolean) {
        this.loggedInStatus = value;
      }

      get isLoggedIn() {
        return this.loggedInStatus;
      }

app-component.ts

  onLogin() {
    this.auth.login(this.username, this.password).subscribe(data => {
      this.auth.setLoggedIn(true);
      localStorage.setItem('login', JSON.stringify(this.auth.isLoggedIn));
      localStorage.setItem('data', JSON.stringify(data));
      this.router.navigate(['']);
    }, err => {
      console.log(err);
    });
  }
}

我猜

constructor(private router: Router) { const login = JSON.parse(localStorage.getItem('login')); if (login !== undefined && login === true) { if (location.pathname === '/login') { this.router.navigate(['']); this.showMenu = false; } else { this.showMenu = true; } } else { if (location.pathname === '/login') { this.showMenu = false; } else { this.showMenu = true; } } }每次刷新都为假。我试图从localStorage读取其值，但我猜这不是使用authguard的正确方法

Answer 1

刷新浏览器时，AuthService将销毁并重建，从而重新初始化其上的每个变量。

应用程序启动时（刷新时），您需要检查localStorage以查看是否存在一些登录信息，并根据此信息在loggedInStatus中设置AuthService。我认为您可以在AuthService构造函数上执行此操作。

Auth Guard刷新后重定向到登录名
