Json request error instead of regular error - websocket

Question

Trying to connect to https://www.xbtce.com via WebSocket (WebSocketSharp)
enter link description here
Here is the login json model
{
"Id": <some unique Id>,
"Request": "Login",
"Params": {
"AuthType": "HMAC",
"WebApiId": <Web API Id>,
"WebApiKey": <Web API Key>,
"Timestamp": <timestamp (e.g. Date.now())>,
"Signature": <signature>,
"DeviceId": <Device Id>
}
}
Here's my code which always gives
{
"Response": "Error",
"Error": "Cannot parse JSON request!"
}
instead of normal response
{
"Id": <your unique Id>,
"Response": "Error",
"Error": <error description from TickTrader Server>
}
My code
private static WebSocket socket = new WebSocket("wss://cryptottlivewebapi.xbtce.net:3020");
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
socket.OnMessage += Socket_OnMessage;
socket.OnOpen += socket_Opened;
socket.OnError += socket_Error;
socket.Connect();
socket.OnClose += socket_Closed;
}
private void Socket_OnMessage(object sender, MessageEventArgs e)
{
if (e.IsText)
{
MessageBox.Show(e.Data.ToString());
}
else
{
MessageBox.Show(e.RawData.ToString());
}
}
private void socket_Closed(object sender, EventArgs e)
{
throw new NotImplementedException();
}
private void socket_Error(object sender, ErrorEventArgs e)
{
MessageBox.Show(e.Exception.ToString());
}
private void socket_Opened(object sender, EventArgs e)
{
string jsonSerialized = JsonConvert.SerializeObject(GetLogin()).ToString() ;
MessageBox.Show(jsonSerialized);
socket.Send(jsonSerialized);
}
LoginParams GetLogin()
{
return new LoginParams
{
Id = Guid.NewGuid().ToString(),
Request = "Login",
Params = new Parameters
{
AuthType = "HMAC",
WebApiId = "my id",
WebApiKey = "my api key",
Timestamp = ((Int32)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds).ToString(),
Signature = Hmac.CreateToken(((Int32)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds).ToString(), "2058e846-0a32-49b9-bc8f-4e28afd0aa9c", "my id", "my key").ToString(),
DeviceId = "WebBrowser"
}
};
}
public static double DateTimeToUnixTimestamp(DateTime dateTime)
{
return (TimeZoneInfo.ConvertTimeToUtc(dateTime) -
new DateTime(1970, 1, 1, 0, 0, 0, 0, System.DateTimeKind.Utc)).TotalSeconds;
}
}
public static class Hmac
{
public static string CreateToken(string timestamp, string id , string key, string secret)
{
string message = timestamp + id + key;
secret = secret ?? "";
var encoding = new System.Text.ASCIIEncoding();
byte[] keyByte = encoding.GetBytes(secret);
byte[] messageBytes = encoding.GetBytes(message);
using (var hmacsha256 = new HMACSHA256(keyByte))
{
byte[] hashmessage = hmacsha256.ComputeHash(messageBytes);
return Convert.ToBase64String(hashmessage);
}
}
}
public class LoginParams
{
public string Id { get; set; }
public string Request { get; set; }
public Parameters Params { get; set; }
}
public class Parameters
{
public string AuthType {
get; set; }
public string WebApiId { get; set; }
public string WebApiKey { get; set; }
public string Timestamp {
get; set; }
public string Signature { get; set; }
public string DeviceId { get; set; }
}
Json serialization output
{
"Id": "be078b3d-2eb8-475a-97fb-89aedf775b78",
"Request": "Login",
"Params": {
"AuthType": "HMAC",
"WebApiId": "myid",
"WebApiKey": "mykey",
"Timestamp": "1467486605",
"Signature": "NbREH0HkPadfuDESuGEHho/FwX+DFdIoCV/D5aW/gv8=",
"DeviceId": "WebBrowser"
}
}
Thanks in advance

Finally found the problem it seems that the time stamp should not be a string but a long
LoginParams GetLogin()
{
return new LoginParams
{
Id = Guid.NewGuid().ToString(),
Request = "Login",
Params = new Parameters
{
AuthType = "HMAC",
WebApiId = "my id",
WebApiKey = "my api key",
Timestamp = ((long)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds).ToString(),
Signature = Hmac.CreateToken(((long)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalMilliseconds), "2058e846-0a32-49b9-bc8f-4e28afd0aa9c", "my id", "my key").ToString(),
DeviceId = "WebBrowser"
}
};
}
