C#Tcp服务器-HTML5网络套接字通信

我正在编写C#Tcp服务器和HTML5 Websocket客户端。但当从客户端向服务器发送消息时，我在C#Tcp服务器上得到了"GET/HTTP/1.1"消息。

c#服务器

using System;using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.IO;
namespace websocket
{
    class Program
    {
        static void Main(string[] args)
        {
            TcpListener server = new TcpListener(IPAddress.Parse("127.0.0.2"), 500);
            server.Start();
            Console.WriteLine("Basladi");
            Console.WriteLine("Bekliyor");
            while (true)
            {
                TcpClient client = server.AcceptTcpClient();
                Console.WriteLine("Baglandi");
                NetworkStream asd = client.GetStream();
                byte[] buffer = new byte[1024];
                String mesaj = Encoding.ASCII.GetString(buffer, 0, asd.Read(buffer, 0, buffer.Length));
                Console.WriteLine(mesaj);
            }
            server.Stop();
        }
    }
}

HTML5 Websocket客户端

function WebSocketTest()
{
     var ws = new WebSocket("ws://127.0.0.2:500");
     ws.onopen = function()
     {
        ws.send("Message to send");
        document.write("Message is sent...");
     };
     ws.onmessage = function (evt) 
     { 
        var received_msg = evt.data;
        document.write("Message is received...");
     };
     ws.onclose = function()
     { 
        document.write("Connection is closed..."); 
     };
}

结果
