iOS Swift GCM / FCM在后台接收通知

Question

应用关闭后，我无法使通知正常工作。

我正在从FCM / GCM（python服务器）发送此邮件：

{
  "registration_ids": ["APA91bEDB9dVf-..."]
  "collapse_key": null,
  "content_available": true,
  "data": {
    "msg": "{\"model\":\"article\",\"data\":\"reload\"}"
  },
  "notification": {
    "body": "my body",
    "sound": "default",
    "title": "my title"
  },
  "priority": "high",
  "time_to_live": 3600
}

所以curl是这样的：

curl --header“授权：密钥= MYKEY” –header“内容类型：application / json” https://fcm.googleapis.com/fcm/send -d'{“ registration_ids”：[“ APA91bEDB9dVf-。 。“]，” collapse_key“：null，” content_available“：true，” notification“：{” body“：” my body“，” sound“：” default“，” title“：” my title“}，”优先级“：” high“，” time_to_live“：3600，” data“：{” msg“：” {\\“ model \\”：\\“ article \\”，\\“ data \\”：\\“ reload \\”}“}} '

终端的响应是：

{“ multicast_id”：6089491211057070352，“ success”：1，“ failure”：0，“ canonical_ids”：0，“ results”：[{“ message_id”：“ 0：1471474398816666％cc062fb9cc062fb9”}]}

在iOS应用程式的[ Background Modes中开启，并显示[ Remote notifications ：

AppDelegate.swift ：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    let settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
    application.registerUserNotificationSettings(settings)
    application.registerForRemoteNotifications()

    FIRApp.configure()
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotification), name: kFIRInstanceIDTokenRefreshNotification, object: nil)

    return true
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
    let notification = UILocalNotification()
    notification.alertBody = "Test"
    notification.alertAction = "open"
    notification.fireDate = NSDate(timeIntervalSinceNow: 1)
    notification.soundName = UILocalNotificationDefaultSoundName
    notification.userInfo = ["UUID": 12312]

    UIApplication.sharedApplication().scheduleLocalNotification(notification)
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Unknown)
}

但是当我发送该消息时，仍然没有任何显示，但是当应用程序打开时，通知工作正常。

有什么问题吗？

Answer 1

{“ to”：“ ID”，“ notification”：{
“ sound”：“默认”，“ title”：“ TITLE”，“ body”：“ BODY”}，“ priority”：“ high”}以这种模式创建通知
