从 C# 服务器向 android 发送 FCM 数据有效负载通知？

Question

我正在尝试使用 FCM 从 C# 服务器向 Android 设备推送通知。我正在使用下面提到的代码发送通知，它工作得非常好，但我也需要发送数据有效负载，但我不知道如何实现它。

public static void SendPushNotification(String user_id,string not_title)
        {
            try
            {
                string applicationID = "AAAAjpeM.......";
                string senderId = ".......";
                string deviceId = user_id;
                WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
                tRequest.Method = "post";
                tRequest.ContentType = "application/json";
                var data = new
                {
                    to = deviceId,
                    notification = new
                    {
                        body = not_title,
                        title = "ABC",
                        sound = "Enabled"
                    }
                };

                var serializer = new JavaScriptSerializer();
                var json = serializer.Serialize(data);
                Byte[] byteArray = Encoding.UTF8.GetBytes(json);
                tRequest.Headers.Add(string.Format("Authorization: key={0}", applicationID));
                tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
                tRequest.ContentLength = byteArray.Length;

                using (Stream dataStream = tRequest.GetRequestStream())
                {
                    dataStream.Write(byteArray, 0, byteArray.Length);
                    using (WebResponse tResponse = tRequest.GetResponse())
                    {
                        using (Stream dataStreamResponse = tResponse.GetResponseStream())
                        {
                            using (StreamReader tReader = new StreamReader(dataStreamResponse))
                            {
                                String sResponseFromServer = tReader.ReadToEnd();
                                string str = sResponseFromServer;
                            }
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                string str = ex.Message;
            }
        }

我试过了，但是没用。

var data = new
                {
                    to = deviceId,
                    data = new
                    {
                        body = not_title,
                        title = "Avicenna",
                        payload="1",
                        sound = "Enabled"
                    }
                };

试试这个：

var data = new
                {
                    to = deviceId,
                    notification = new
                    {
                        body = not_title,
                        title = "ABC",
                        sound = "Enabled"
                    },  
                    data = new
                    {                        
                        payload="1"
                    }
            };
