Php FCM iOS在后台接收通知

Question

我正在用PHP编写通用FCM功能，以便向Android和IOS设备发送远程通知。

在IOS中，我在前台收到通知，但当App在后台时，我没有收到任何通知。

我从网上尝试了几种方法，没有任何帮助。

请帮我正确设置服务器端

尝试1：

$feildAryVar = array(
        'content_available' => true,
        'registration_ids' => $FcmUidVar,
        'data' => array("MsgKey"=>json_encode($msgToSendVar)),
        'notification' => array(
                "title"=>"Fcm TtlMsg",
                "body"=>"Fcm Dtl Msg",
                "content_available"=> true)
    );

尝试2：

$feildAryVar = array(
        'registration_ids' => $FcmUidVar,
        'data' => array("MsgKey"=>json_encode($msgToSendVar)),
        'notification' => array(
                "title"=>"Fcm Title Msg",
                "body"=>"Fcm Detail Msg",
                "content_available"=> true)
    );

Ios App Deligate：

func application(appPsgVar: UIApplication,
                 didReceiveRemoteNotification userInfo: [NSObject : AnyObject])
{
    FIRMessaging.messaging().appDidReceiveMessage(userInfo)
}

func application(AppPsgVar: UIApplication,
                 didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                                              fetchCompletionHandler handler: (UIBackgroundFetchResult) -> Void)
{
    handler(UIBackgroundFetchResult.NewData)
    FIRMessaging.messaging().appDidReceiveMessage(userInfo)
}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void)
{
    print("userNotificationCenter : Forground")

    completionHandler([.Alert,.Sound,.Badge])
}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void)
{
    //Code Todo After User presess notification
}

func applicationReceivedRemoteMessage(remoteMessage: FIRMessagingRemoteMessage)
{
    let fcmNfnVar = remoteMessage.appData
    print("Received Notification : \(fcmNfnVar)")
}
