在阅读了很多答案之后，我在这里发布了这个，因为我的问题仍然未知。如果我从firebase控制台发送通知，我会收到通知，但如果我转到我的应用程序后端并执行根据后端人员生成通知的功能，我没有收到通知。 android开发人员正在收到通知。
因为我不知道哪些信息可能有用，我在这里粘贴我的AppDelegate.swift课程：

如果我从firebase控制台发送它们，我会得到它们。但是如果应用程序的后端生成通知我就不会得到它。根据Firebase文档，如果后端人员拥有FCM，他可以去发送通知，并且他有正确的FCM，我也检查过。
在解释了这个场景后，他告诉我，之前Android机器人的情况也是如此（接收到firebase通知，但服务器的通知没有），然后事实证明这个问题是在android家伙端。当他收到通知时，他没有发出通知，所以根据他的话，问题是在我的结束时我没有在收到通知时提出通知（我没有从服务器收到通知，因为当我得到它时从firebase它显示在锁定屏幕上）。还有他需要实施的证书吗？因为我有一张我在firebase上上传的证书。

你可以尝试这一点吗？ //接收iOS 10设备的显示通知。
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
// Change this to your preferred presentation option
completionHandler([.alert, .badge, .sound]) // <-----
}
答案 1 :(得分：1)
我认为这是由于通知的结构，至少如果我理解了这个问题。我曾经遇到过同样的问题，后端人员认为它正在Android上运行。但它已在文档中介绍。
结构应该看起来像described here
"notification" : {
"body" : "great match!",
"title" : "Portugal vs. Denmark"
}
无论他们输入的数据是什么，仍会收到，但不会用于提示通知（在Android上会显示）。没有必要提取任何东西只是告诉后端人员为你添加这个。
答案 2 :(得分：1)
在发送通知之前，请确保您已添加＆＃34; content_available＆＃34; ：JSON有效内容中的：true 。否则，您无法在后台模式下获得推送通知。
"notification" : {
"content_available" : true,
"body" : "this is body",
"title" : "this is title"
}

您是否尝试将其添加到didFinishLaunchingWithOptions:
// Check if launched from notification
// 1
if let notification = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? [String: AnyObject] {
// 2
let aps = notification["aps"] as! [String: AnyObject]
// 3
delay(1.0, closure: {
NSNotificationCenter.defaultCenter().postNotificationName("openedFromPush", object: nil, userInfo: ["info":notification])
})
}

在firebase控制台上再次上传您的证书或p8文件。
