本篇文章主要内容：jsoncpp的使用，Cocos2dx网络编程，聚合数据星座运势接口使用。
1、jsoncpp使用：
jsoncpp的生成请参考博客：Jsoncpp使用详解以及链接问题解决
2、聚合数据星座运势接口使用：
我们先登上聚合数据官网，申请相关的数据后，就可以得到APPKEY等信息，调试如下：
3、Cocos2dx网络编程：源码下载请点击（源码中包括jsoncpp文件）

}
最后截图效果：
温馨提示：出现中文乱码，解决方案如下：
extension::CCHttpRequest post
加上这段代码
/*std::vector<std::string> headers;
headers.push_back("Content-Type: application/json; charset=utf-8");
request->setHeaders(headers);*/
