第一次学习JavaScript WebSocket做了个小实验，用它去连接本地C# Server，结果
server上显示连接成功了，但JS却一直处于正在连接状态。下面的代码解释部分代表输
出（未输出）的状态。如果在Javascript后加上cnt.send('abc')，错误信息为：
InvalidStateError: Failed to execute 'send' on 'WebSocket': Still in
CONNECTING state.。等很久都没有timeout error，说明Javascript一直在连接Server
。但是Server已经显示连接成功了呀。求牛人指点！
Javascript:
var cnt=new WebSocket("ws://localhost:8001");
cnt.onopen=function(){console.log('connection setup!');};// not shown
cnt.onmessage=function(msg){console.log(msg);}; // not shown
cnt.onerror=function(){console.log('error');}; // shown if close server
C#(Server):
TcpListener server = new TcpListener(IPAddress.Parse("127.0.0.1"
),8001);
server.Start();
Console.WriteLine("Server started!"); //success
TcpClient connect = server.AcceptTcpClient();
Console.WriteLine("Connected!"); // success
NetworkStream ns = connect.GetStream();
Console.WriteLine("Sending msg"); // success
String msg="abc";
ns.Write(Encoding.ASCII.GetBytes(msg), 0, 3);
Console.WriteLine("Reading reply"); // success
StreamReader sr = new StreamReader(ns);
Console.WriteLine(sr.ReadToEnd());
Console.ReadLine();
