It's a quick fix, simply add "priority": "high" in your payload next to "notification" etc. and the iOS Notification will work when the app is in the background.

这是一个快速修复，只需在“通知”等旁边的有效负载中添加“优先级”：“高”，当应用程序在后台时，iOS通知将起作用。

So this will work:

这样可行：

"to":"TOKEN ID",
"notification" : {
  "body" : "test"
},
"priority": "high"
}

What worked for me was simply adding title to the notification like this:

对我有用的只是在通知中添加标题，如下所示：

"notification" : {
  "title": "foo",
  "body" : "bar"
}

    }
}
