如何使用Firebase读取推送通知中发送的自定义数据

Question

我正试图在iOS应用程序(Swift(中使用Firebase检索推送通知中发送的"数据">

这是我用来发送通知的代码：

{
"to": "dWB537Nz1GA:APA91bHIjJ5....",
"data":
{
"message": "Offer!",
"mediaUrl": "https://upload.wikimedia.org/wikipedia/commons/thumb/2/2a/FloorGoban.JPG/1024px-FloorGoban.JPG"
},
"notification":
{
"body": "Enter your message",
"sound": "default"
}
}

我只实现了一种从通知中读取数据的方法：

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
//checked where I can get custom data which I sent but no success
let notification =  response.notification.request.content.body
print("Notification recived content:(response.notification.request.content)")
print("userNotificationCenter : didReceive response body : (notification)")
print("userNotificationCenter : didReceive response user info : (response.notification.request.content.userInfo)")
print("userNotificationCenter : response : (response)")

completionHandler()
}

检查了上面的方法，在那里我可以获得我发送的自定义数据，但没有成功

我在很多地方寻找解决方案，但都没有成功。请帮助我检索自定义数据。

提前谢谢！

我在swift方面这样使用：

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {

if let menu = userInfo["Menu"] as? NSString {
print(menu)
}
Messaging.messaging().appDidReceiveMessage(userInfo)
completionHandler(UIBackgroundFetchResult.newData)
}

这是我用来发送通知的代码：

{
"to": "/topics/....",
"data":
{
"Menu": "Summary"
},
"notification":
{
"title": "Header",
"text": "Message",
"sound": "default"
}
}
