When opening a websocket connection (in JavaScript) to my custom server I wrote (C#), I want to include a parameter at the end of the URL for example 'ws://127.0.0.1:9003/myParameter'.
var socket = new WebSocket('ws://127.0.0.1:9003?myParameter=1');
socket.onopen = function () {
deferred.resolve(true);
socket.close();
};
On the server side I have this method accepting connections:
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
try
{
t.Start();
while (true)
{
TcpClient c = t.AcceptTcpClient();
WebSocketClient w = new WebSocketClient(c);
webSocketClientManager.AddClient(w);
}
}
catch (Exception ex)
{
// log error
}
}
}
I have no issues establishing the connection. What I would like is to somehow read/see if 'myParameter' exists in the URL as it is trying to connect.
TIA
var ws = new WebSocket ("ws://example.com/?name=nobita");
ws.SetCookie (new Cookie ("name", "nobita"));
public class Chat : WebSocketBehavior
{
private string _name;
...
protected override void OnOpen ()
{
_name = Context.QueryString["name"];
}
...
}
Alternatively, you could send the parameters you wanr as a message from the client after connection is complete, then in onMessage you could capture the message and deal with it as you wish.
WebSocket Client:
public static void Main (string[] args)
{
using (var ws = new WebSocket ("ws://..../Laputa")) {
ws.OnMessage += (sender, e) =>
Console.WriteLine ("Parm: " + e.Data);
ws.Connect ();
ws.Send ("Parameters");
Console.ReadKey (true);
}
}
Server:
public class Laputa : WebSocketBehavior
{
protected override void OnMessage (MessageEventArgs e)
{
var msg = e.Data == ;
Send (msg);
}
}
public class Program
{
public static void Main (string[] args)
{
var wssv = new WebSocketServer ("ws://..../Laputa");
wssv.AddWebSocketService<Laputa> ("/Laputa");
wssv.Start ();
Console.ReadKey (true);
wssv.Stop ();
}
}
