业务需求
共享文件夹、盘会导致系统安全性下降，故IT部门需要搜集公司中每台电脑的共享情况，并且进行上报
关键字
WMI查询、Get请求、C++网络库mongoose
前置需要
1、简单C++语法知识
2、mongoose库的导入
3、C++项目的启动
代码
复制并不能直接使用，需导入mongoose库
完整github项目代码：https://github.com/Canwaiting/check_netshare
修改其中的变量url，app，white_list[]，这个项目就是你的了

}CPP折叠复制全屏牢骚
本来是用C#写的，但是打出来的包几十M，不符合要求；还是得用回C++，各种轮子都要自己造，还得转字符；差点就完不成了 : )
