Question

我有一个websocket客户端的问题。

它似乎在IE和Edge中运行良好。服务器响应消息，客户端接收并显示此消息，但是当我的Android设备运行此代码时，错误处理程序将被触发并立即关闭连接。

错误处理程序给我一条消息：“undefined”

这是我的客户：

      function openSocket(){
                
            if ("WebSocket" in window)
            {
               alert("WebSocket is supported by your Browser!");

                            };

                            ws.onmessage = function (evt)
                            {

                                alert("Message = " + received_msg);
                            };

                            ws.onclose = function ()
                            {
                                // websocket is closed.
                                alert("Connection is closed...");
                            };
							ws.onerror = function(evt)
							{
								alert("Error: " + evt.data);
							};
            } else
            {
                alert("WebSocket NOT supported by your Browser!");
            }

  		<a href="javascript:openSocket();" class="ui-btn ui-btn-inline" id="button">Keyboard</a>
  	</div>
  </body>
</html>

我的服务器只是回复了一条消息：

@OnMessage
public String onMessage(String message) {
    return "Got it.";
}

Android设备上的WebSocket错误，适用于IE
