cocos2d-x-3.5 socket编程

本人之前一直想搞搞用cocos进行网络编程，也在网上逛了很久，但令人纳闷的是，网上的大牛们要么讲了些socket编程的原理，要么讲了些cocos2dx，socket的独特之处。但是作为一名菜鸟，能把程序跑起来，是最基本的一步，也是对自信心一个很大的鼓励。在网上找了很久，都 没有一整套完整的源码。小弟不才，自我摸索，搞了一个简单的TCP/IP协议的简单连接。

学习之些，对socket总得有一个基本的了解吧，此内容不少，给出一个别人的博客链接，大家可以先看看这篇博客。

socket基础学习

要进行socket编程，首先要有socket包，点击下载。该包是从别人来下载过来，别人已经封装好了，在windows下和linux下都能运行。

看完上面所给的博客后。我贴上我的代码。理工科，文章写得不好，尽量少费话，直接上代码。
