我使用QWebSocketServer提供与javascript websocket的通信

该代码与Qt示例中的EchoServer非常相似

javascript端代码如下所示：

<!DOCTYPE HTML>
<html>
<head>
<script type="text/javascript">
function WebSocketTest()
{
  if ("WebSocket" in window)
  {
     //alert("WebSocket is supported by your Browser!");
     // Let us open a web socket
     var ws = new WebSocket("ws://localhost:12345");
     ws.onopen = function()
     {
        // Web Socket is connected, send data using send()
        ws.send("Message to send");
        alert("Message is sent...");
     };
     ws.onmessage = function (evt) 
     { 
        var received_msg = evt.data;
        alert("Message is received...");
     };
     ws.onclose = function()
     { 
        // websocket is closed.
        alert("Connection is closed..."); 
     };

     ws.onerror = function(error){
        console.log('Error detected: ' + JSON.stringify(error));
     }

  }
  else
  {
     // The browser doesn't support WebSocket
     alert("WebSocket NOT supported by your Browser!");
  }
}
</script>
</head>
<body>
<div id="sse">
   <a href="javascript:WebSocketTest()">Run WebSocket</a>
</div>
</body>
</html>

这个错误意味着什么？这是否意味着我们不能使用QWebSocketServer来支持javascript websocket？

在这个错误中没有太多的内容。你应该提供更多关于你的设置的信息。我需要提供什么样的信息？我试过你的代码，它对我来说很好。你从哪里得到这个错误的？服务器端还是浏览器中？我使用的是Qt5.4.0beta和FF 33。@Vin那是很久以前的事了。我扔掉了websocket，所以问题就解决了。我只是想知道这个错误。。。有什么线索吗？抱歉，以前从未见过错误或类似的情况。我猜您使用的Qt版本可能与您使用的浏览器存在兼容性问题。
