我正在使用 Angular6 中的 SwPush 在 PWA 中推送通知。为此，我使用@angular/service-worker。我能够从节点服务器发送通知。但是当我点击收到的通知时，它无法路由所需的 url。我正在使用web-push module in node.js，这是有效载荷：

        "payload": {
        "title": "Sample Notification",
        "actions": [
          {
            "action": "opentweet",
            "url":"https://pwa-sw-push-notifications.firebaseapp.com",
            "title": "Open tweet"
          }
        ],
        "body": "A sample data to check the notification availability!",
        "dir": "auto",
        "icon": "https://pwa-sw-push-notifications.firebaseapp.com/assets/icons/icon-72x72.png",
        "badge": "https://pwa-sw-push-notifications.firebaseapp.com/assets/icons/icon-72x72.png",
        "lang": "en",
        "url": "https://pwa-sw-push-notifications.firebaseapp.com",
        "renotify": true,
        "requireInteraction": true,
        "tag": 926796012340920300,
        "vibrate": [
          100,
          50,
          100
        ],
        "data": {
          "url": "https://pwa-sw-push-notifications.firebaseapp.com",
          "favorite_count": 0,
          "retweet_count": 0
        }
      }

我在用

var webPush=require('web-push');

//sub is userSubscriptionObject to send the notifications to subscribed user browser.
webPush.sendNotification(sub, JSON.stringify(payload))))

在角度，

export class IndexComponent implements OnInit {
  users: any = [];
  constructor(
    private http: HttpClient, 
    private router: Router, 
    private swPush: SwPush) {
    console.log('this is index');
  }
  ngOnInit() {
    this.getCoins();
  }
  subscribeNotifications(){
        this.swPush.requestSubscription({
      serverPublicKey: "BMW3STH0ODuNdhFVAZIy8FUDEwt2f8LLpWBiBnz8WE0_558rZc4aLbZUD9y-HxMlfCtyE5OD0mk3xa2oFJZu5n0"
    }).then(sub => {
        console.log("Notification Subscription: ", sub);
        this
        .http
        .post('https://e1a2e469.ngrok.io/sub/subscribeNotifications', sub);.subscribe(
          () => {
            console.log('Sent push subscription object to server.');        
        },
          err => console.log('Could not send subscription object to server, reason: ', err)
        );
      })
      .catch(err => console.error("Could not subscribe to notifications", err));
  }
  unsubscribeNotifications(){
    this.swPush.subscription.pipe(take(1)).subscribe(subscriptionValue=>{
      console.log('this is un subscription', subscriptionValue);
        this
        .http
        .post('https://e1a2e469.ngrok.io/sub/unsubscribeNotifications', subscriptionValue);
          .subscribe(
          res => {
            console.log('[App] Delete subscriber request answer', res)
            // Unsubscribe current client (browser)
            subscriptionValue.unsubscribe()
              .then(success => {
                console.log('[App] Unsubscription successful', success)
              })
              .catch(err => {
                console.log('[App] Unsubscription failed', err)
              })
          },
          err => {
            console.log('[App] Delete subscription request failed', err)
          }
    );
  });
}
  sendNotifications(){
    console.log('subscribeNotifications')
    this
      .http
      .post('https://e1a2e469.ngrok.io/sub/sendNotifications', null).subscribe(res=>{
      console.log('subscribed successfully');
    });
  }
}

我的意图是，当用户点击它应该路由到的通知时

https://pwa-sw-push-notifications.firebaseapp.com.

我曾尝试在上述对象中以不同的参数提供此 URL，但actions[0].action.url URL data.url没有任何效果。所以我很困惑在哪里提供 URL 以使其成为可能。谁能帮帮我？

谢谢你。

据我所知，您的有效载荷没有任何问题。有效负载只是传递给您的浏览器的数据，在您的浏览器端，您需要实现notificationClick处理程序以处理有效负载数据，即导航到所需的 URL。可以在 service worker 中实现一个简单的notifictionClick处理程序，如下所示：

this.scope.addEventListener('notificationclick', (event) => {
    console.log('[Service Worker] Notification click Received. event', event);
    event.notification.close();
    if (clients.openWindow && event.notification.data.url) {
      event.waitUntil(clients.openWindow(event.notification.data.url));
    }
  });
