如何从C#控制台应用程序发送通知

问题描述：

我想创建一个控制台应用程序，该应用程序用于通过Goolge Firebase通知将通知发送到不同的移动设备，

I want to create console application which is used to send notifications to different mobile devices via Goolge Firebase Notifications,

我从链接我收到状态代码为500的内部服务器错误

I am getting internal server error with status code 500

try{
    string url = @"https://fcm.googleapis.com/fcm/send";
    WebRequest tRequest = WebRequest.Create(url);
    tRequest.Method = "post";
    tRequest.ContentType = "application/json";

    string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message=" + "This is the message" + "&data.time=" + System.DateTime.Now.ToString() + "&registration_id=" + deviceId + "";
    var data = new
    {
        to = deviceId,
        notification = new
        {
            body = "This is the message",
            title = "This is the title"

        }
    };
    string jsonss = Newtonsoft.Json.JsonConvert.SerializeObject(data);

    Byte[] byteArray = Encoding.UTF8.GetBytes(jsonss);              
    tRequest.Headers.Add(string.Format("Authorization: key={0}", applicationID));
    tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
    tRequest.ContentLength = byteArray.Length;
    tRequest.ContentType = "application/json";
    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();
                    Console.Write(sResponseFromServer);
                }
            }
        }
    }
}

catch (Exception ex)
{
    Console.Write(ex.Message);
    {
        var sss = ex.Message;
        if (ex.InnerException != null)
        {
            var ss = ex.InnerException;
        }
    }

}

这是使用C#发送通知的代码，我已经使它工作了

Here is the code to send notification using C#, I have made it working

 WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
                        tRequest.Method = "post";
                        tRequest.ContentType = "application/json";
                        var objNotification = new
                        {
                            to = notification.DeviceToken,
                            data = new
                            {
                                title = notification.NotificationTitle,
                                body = notification.NotificationBody
                            }
                        };
                        string jsonNotificationFormat = Newtonsoft.Json.JsonConvert.SerializeObject(objNotification);

                        Byte[] byteArray = Encoding.UTF8.GetBytes(jsonNotificationFormat);
                        tRequest.Headers.Add(string.Format("Authorization: key={0}", serverKey));
                        tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
                        tRequest.ContentLength = byteArray.Length;
                        tRequest.ContentType = "application/json";
                        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 responseFromFirebaseServer = tReader.ReadToEnd();

                                        FCMResponse response = Newtonsoft.Json.JsonConvert.DeserializeObject<FCMResponse>(responseFromFirebaseServer);
                                        if (response.success == 1)
                                        {
                                            new NotificationBLL().InsertNotificationLog(dayNumber, notification, true);
                                        }
                                        else if (response.failure == 1)
                                        {
                                            new NotificationBLL().InsertNotificationLog(dayNumber, notification, false);
                                            sbLogger.AppendLine(string.Format("Error sent from FCM server, after sending request : {0} , for following device info: {1}", responseFromFirebaseServer, jsonNotificationFormat));

                                        }

                                    }
                                }

                            }
                        }

此处是此代码中使用的FCMResponse类，用于存储从FMServer发送的响应

Here is class FCMResponse used in this code to store response sent from FMServer

 public class FCMResponse
{
    public long multicast_id { get; set; }
    public int success { get; set; }
    public int failure { get; set; }
    public int canonical_ids { get; set; }
    public List<FCMResult> results { get; set; }
}
  public class FCMResult
{
    public string message_id { get; set; }
}
