websocket 客户端抛错 INVALID_STATE_ERR

websocket 客户端抛错 INVALID_STATE_ERR

在做websocket的时候，服务器连接正常但是客户端总是抛出错误：socket.send(msg) INVALID_STATE_ERR: DOM Exception 11
经过测试判断是send（）这里出的问题。但是实在不知到是什么问题，服务器状态如下：
[info]init...
[info]init end
[info]have connected peer 0
[info]socket_select...
[info]socket_select end
[info]readable socket:1
[info]writeable socket:1
[info]accept...
[info]accept end
[info]Resource id #8 CONNECTED
[info]have connected peer 0
[info]socket_select...
希望有人可以帮忙看看，具体代码如下：

  <html>
  

  <head>
  

  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
  

  <title>WebSocket Client</title>
  

  

  <style>
  

  html,body{font:normal 0.9em arial,helvetica;}
  

  #log {width:440px; height:200px; border:1px solid #7F9DB9; overflow:auto;}
  

  #msg {width:330px;}
  

  </style>
  

  

  <script>
  

  var socket;
  

  

  function init(){
  

  var host = "ws://127.0.0.1:12345/WebSoket2/server.php";
  

  try{
  

  socket = new WebSocket(host);
  

  

  log('WebSocket - status '+socket.readyState);
  

  

  socket.onopen    = function(msg){ log("Welcome - status "+this.readyState); };
  

  socket.onmessage = function(msg){ log("Received: "+msg.data); };
  

  socket.onclose   = function(msg){ log("Disconnected - status "+this.readyState); };
  

  }
  

  catch(e) {
  

  log(e);
  

  }
  

  $("msg").focus();
  

  }
  

  

  function send(){
  

  var txt,msg;
  

  txt = $("msg");
  

  msg = txt.value;
  

  if(!msg){ alert("Message can not be empty"); return; }
  

  txt.value="";
  

  txt.focus();
  

  log(socket);
  

  try{ socket.send(msg); log('Sent: '+msg); } catch(ex){ log("send error: " + ex); }
  

  }
  

  function quit(){
  

  log("Goodbye!");
  

  socket.close();
  

  socket=null;
  

  }
  

  

  // Utilities
  

  function $(id){ return document.getElementById(id); }
  

  function log(msg){ $("log").innerHTML+="<br>"+msg; }
  

  function onkey(event){ if(event.keyCode==13){ send(); } }
  

  </script>
  

  

  </head>
  

  <body onload="init()">
  

  <h3>WebSocket</h3>
  

  <div id="log"></div>
  

  <input id="msg" type="textbox" onkeypress="onkey(event)"/>
  

  <button onclick="send()">Send</button>
  

  <button onclick="quit()">Quit</button>
  

  </body>
  

  </html>

我也遇到同样的问题。这应该是服务器端的问题吧
很明显socket协议握手失败了，服务器端的问题
我做了一个简单的服务器端，你可以测试一下 https://github.com/duguying/rocket
