单击@angular/service-worker推送通知的操作部分

Question

我一直在尝试将用户重定向到来自后端(PHP)的Web推送的“操作”部分。

    return (new WebPushMessage)
        ->title('Title')
        ->icon('icon.png')
        ->body('Body Msg')
        ->action('Open Notification', 'open_notification')
        ->data(['id' => $notification->id,'url'=>'http://somewhere']);

默认服务人员使用：

self.addEventListener('notificationclick', function(event) {
    console.log('On notification click: ', event.notification.tag);
    event.notification.close();

    // This looks to see if the current is already open and
    // focuses if it is
    event.waitUntil(clients.matchAll({
       type: "window"
    }).then(function(clientList) {
       for (var i = 0; i < clientList.length; i++) {
          var client = clientList[i];
              if (client.url == '/' && 'focus' in client)
                 return client.focus();
       }
       if (clients.openWindow)
          return clients.openWindow('/');
    }));
});

Angular 5使用

import {SwPush, SwUpdate} from '@angular/service-worker'; 

我的问题是如何在前端(Angular 5)中使用@angular/service-worker来解释这一点

Answer 1

在Github上收到来自u-ryo的回复

有一种解决方法。将以下代码添加到行this.scope.addEventListener('push'，(event) => this.onPush(Event))；(第1775行)周围的ngsw-worker.js中。

  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));
    }
  });

然后，您可以在"notification.data.url“中指定URL。

如果你想要有动作，并且每个动作都有不同的url，这是我的解决方案。

    this.scope.addEventListener('notificationclick', (event) => {
        event.notification.close();
        var payload = event.notification.data;
        var url = payload.url;
        if (event.action && payload.actions && payload.actions.length) {
            var actions = payload.actions.filter(x => x.action == event.action);
            if (actions.length && actions[0].url) {
                url = actions[0].url;
            }
        }
        if (clients.openWindow && url) {
            event.waitUtil(clients.openWindow(url));
        }
    });
