iOS静默推送通知已取消 [英] iOS silent push notification cancelled

问题描述

在我的应用程序中，我使用静默推送通知来定期进行通信，但是由于没有处理我在不启动应用程序时收到的静默推送通知，因此我遇到了麻烦.操作系统版本为iOS12.我正在使用FCM发送推送通知.有人遇到同样的问题吗?

In my application, I use silent push notification in order to communicate regularly, but I am in trouble because the silent push notification I received while not launching the application is not processed. OS version is iOS12. I am using FCM to send push notifications. Is there anyone with the same problem?

当您收到通知静默推送通知时，下面是控制台日志.

Below is the console log when you receive a notification silent push notification.

推荐答案

在我的案例中，问题是有效载荷中其他属性的泛滥.我在开始时就使用了这个有效负载:

In my case the problem was the lake of other properties in the payload. I was using this payload at the beggining:

{"aps":{"content-available":1}}

但添加声音属性可解决此问题:

but adding the Sound property fixed the problem:

{"aps":{"content-available":1, "sound":""}}
