使用插件：besthttp 1.10

u3d版本：5.4.0

代码：找的网上的一篇代码，自己偷懒没写 只简单测试了下

        //注册事件之后，我们就可以开始连接
        webSocket.Open();
        //在这一步之后，我们将收到一个OnOpen事件，我们可以开始发送消息到服务器
        webSocket.Send("Message to the Server");
        byte[] buffer = new byte[1024];

脚本中对应的方法填入到对应的button中，执行，不需要切换成webgl直接PC端测试能用，
服务端测试地址：http://ruyice.com/test  我是在这个网址中的websocket进行测试的，不用自己麻烦的搭建服务端

在脚本中的url中填写上图中的测试ws网址：ws://demos.kaazing.com/echo

测试结果：

 

 能运行，测试过程中出现的问题，如果在OnDestory（）和OnApplicationQuit()中使用websocket.close()的话就会报错，虽然不影响什么，但是总看着不舒服，所以直接把close方法去掉了，程序关掉的同时也关掉了websocket的，就这样了
