推荐答案

通常，一旦您收到来自 GCM(Google Cloud Messaging)的推送消息，您就必须在浏览器中显示推送通知.此处的第 3 点提到了这一点:

Generally as soon as you receive a push message from GCM (Google Cloud Messaging) you have to show a push notification in the browser. This is mentioned on the 3rd point in here:

https://developers.google.com/web/updates/2015/03/push-notificatons-on-the-open-web#what-are-the-limitations-of-push-messaging-in-chrome-42

因此，尽管您收到了来自 GCM 的推送消息，但您收到的推送通知带有一些默认消息，例如此站点已在后台更新"，但您可能会以某种方式跳过推送通知.

So it might happen that somehow you are skipping the push notification though you got a push message from GCM and you are getting a push notification with some default message like "This site has been updated in the background".
