cocos2d-x HttpClient

版本：cocos2d-x2.2

联网游戏开发经常遇到http编程，写一个示例，加深记忆。

想要在cocos2d-x中使用HttpClient需要引用cocos2d-x 的相关库。

右键单击项目->属性->c/c++->常规，在右边的附件包含目录中添加cocos2dx的extensions目录对应的路径。

然后,右键单击项目->属性->链接器->输入，在右边的附件依赖项中添加libcurl_imp.lib和libExtensions.lib两个库

2.1.3版本到这里已经能运行了，但是2.2版本还要加一个库

pthreadVCE2.lib
