Question

有人可以帮助我吗？这是我的代码：

private void btnSendNotification_Click(object sender, EventArgs e)
    {
        tbxResponse.Clear();
        string response = PushNotification();
        tbxResponse.Text = response;

    }

    private static string PushNotification()
    {
        string response;

        try
        {
            // From: https://console.firebase.google.com/project/x.y.z/settings/general/android:x.y.z

            // Projekt-ID: x.y.z
            // Web-API-Key: A...Y (39 chars)
            // App-ID: 1:...:android:...

            // From https://console.firebase.google.com/project/x.y.z/settings/
            // cloudmessaging/android:x,y,z
            // Server-Key: AAAA0...    ...._4

            string serverKey = "AAAAs8qv4ZM:APA91bEED4RRv-u3ALAObLmBlTMRwwRtfMyVDZweB6tCTz4y33sIR_D-p7chnFsVKAXF3Mg2ajmX6_gYPTaBXew0IbRe8GfZHpd0LW0gy415-5DJPQZBmY9BUXAMz6qEdf6bQ_FLQKgZqgv-pyTK7unV4pDattdGag"; // Something very long
            string senderId = "772199670163";
            string deviceId = "GxzonRZepM:APA91bG3x1EhCU0fpg06T7MyCeFKCs-tY8mb3zKqOWh9docYJXkJkSZ6oq2a6UEorZf9rAwHxsAzu28X0e0coRPX5HJzLQ27atCc_Xh6Xoem2LLWOaC3c76Hl78JSyziIt-9aL4OF88p"; // Also something very long, 
            // got from android
            //string deviceId = "//topics/all";             // Use this to notify all devices, 
            // but App must be subscribed to 
            // topic notification
            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 = "Greetings",
                    title = "Augsburg",
                    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}", serverKey));
            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();
                            response = sResponseFromServer;
                        }
                    }
                }
            }
        }
        catch (Exception ex)
        {
            response = ex.Message;
        }

        return response;
    }

但是我在输出中给出了一个错误： {“ multicast_id”：4889294147329191934，“成功”：0，“失败”：1，“ canonical_ids”：0，“结果”：[{“错误”：“ MismatchSenderId”}]}}

我必须做什么？
