I have to hide a push notification after 1 minute. What should I do in my service worker to achieve this?

推荐答案

您可以使用 Notification.close() 方法.您可以使用Notification 对象链接到您的通知NotificationEvent 对象，由 ServiceWorkerRegistration.showNotification 解析为.

You can use the Notification.close() method. You can get the Notification object linked to your notification by using the NotificationEvent object that the promise returned by ServiceWorkerRegistration.showNotification resolves to.

像这样:

self.addEventListener('push', event => {
  event.waitUntil(
    self.registration.showNotification('Title', {
      body: 'Body.',
    })
    .then(notificationEvent => {
       let notification = notificationEvent.notification;
       setTimeout(() => notification.close(), 60000);
    })
  );
});

另一种可能的解决方案是获取您使用 ServiceWorkerRegistration.getNotifications.

Another possible solution is to get all the notifications you're showing with ServiceWorkerRegistration.getNotifications.

例如:

self.addEventListener('push', event => {
  event.waitUntil(
    self.registration.showNotification('Title', {
      body: 'Body.',
    })
    .then(() => self.registration.getNotifications())
    .then(notifications => {
      setTimeout(() => notifications.forEach(notification => notification.close()), 60000);
    })
  );
});
