u3d:使用websocket最簡單的測試通信

使用插件：besthttp 1.10

u3d版本：5.4.0

代碼：找的網上的一篇代碼，自己偷懶沒寫 只簡單測試了下

腳本中對應的方法填入到對應的button中，執行，不需要切換成webgl直接PC端測試能用，
服務端測試地址：http://ruyice.com/test  我是在這個網址中的websocket進行測試的，不用自己麻煩的搭建服務端

在腳本中的url中填寫上圖中的測試ws網址：ws://demos.kaazing.com/echo

測試結果：

 

 能運行，測試過程中出現的問題，如果在OnDestory（）和OnApplicationQuit()中使用websocket.close()的話就會報錯，雖然不影響什么，但是總看着不舒服，所以直接把close方法去掉了，程序關掉的同時也關掉了websocket的，就這樣了
