我正在努力使用 Angular6 中的 SwPush 在 PWA 中推送通知。为此,我使用@angular/service-worker。我可以从 Node 服务器发送通知。但是当我点击收到的通知时,它无法路由所需的网址。我在node.js中使用web-push模块
,这是有效负载:
"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
}
}
我正在使用
var webPush=require('web-push');
//sub is userSubscriptionObject to send the notifications to subscribed user browser.
webPush.sendNotification(sub, JSON.stringify(payload))))
有角度,
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,当用户单击通知时,它应该路由到
https://pwa-sw-push-notifications.firebaseapp.com
。
我尝试在上述对象的不同参数中提供此 URL,例如 actions[0].action.url
URL
data.url
但没有任何作用。所以我很困惑在哪里给出 URL 才能使其成为可能。有人可以帮我吗?
谢谢。
最佳答案
据我所知,您的有效负载没有任何问题。有效负载只是传递到浏览器的数据,在浏览器端,您需要实现 notificationClick
处理程序才能处理有效负载数据,即导航到所需的 URL。一个简单的 notificationClick
处理程序可以在 Service Worker 中实现,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));
}
});
