iOS未从Firebase Cloud Messaging接收通知

问题描述：

我希望推送通知仅包含标题.当我从Firebase控制台发送消息时，它可以工作，但是当我尝试通过API进行操作时，它不适用于iOS(在Android上工作正常).

I want the push notification to only contain the title. When I send a message from the Firebase console, it works, but when I try to do the same via the API, it doesn't work for iOS (works fine on Android).

我要完成的工作是仅在未打开应用程序时在通知抽屉中显示的通知中显示标题.如果添加了正文，则它会显示在通知的标题下.

What I'm trying to accomplish is to only show the title in the notification that shows up in the notification drawer when the app is not open. If body is added, it is shown under the title in the notification.

这是我发送的推送通知:

This is the push notification I'm sending:

{
    "to": "/topics/breaking",
    "priority":"high",
    "notification": {
        "title":"Dette er en test"
    }
}

我什么也没回来

如果我在通知中添加正文，

If I add body to the notification:

{
    "to": "/topics/breaking",
    "priority":"high",
    "notification": {
        "title":"Dette er en test",
        "body":"hello"
    }
}

我得到这个回报

{
    aps = {
        alert = {
            body = Hello;
            title = "Dette er en test";
        };
    };
    "gcm.message_id" = "xxxxxxx";
}

以下是打印出我收到的内容的代码:

Here is the code to print out what I receive:

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
    self.parseNotification(application, userInfo: userInfo as NSDictionary!)
}

func parseNotification(_ application: UIApplication, userInfo: NSDictionary!) {

    print(userInfo)
}

如何在不添加请求正文的情况下在iOS上获取通知?

How can I get the notification on iOS without adding body to the request?

答

我知道了！

如果我放下标题并仅张贴正文，那么它会起作用.

If I drop the title and ONLY post body it works.

{
    "to": "/topics/breaking",
    "priority":"high",
    "notification": {
        "body": "Dette er en test"
    }
}
