VC实现http发送get和post请求
get请求
首先通过前面介绍的抓包工具获取请求的详细内容，然后再通过VC拼接Header，函数如下：bool CXXX::http_get_eng_mode()
{
//<?xml version=\"1.0\" encoding=\"US-ASCII\"?>
<RGW><param><method>call</method><session>000</session><obj_path>cm</obj_path><obj_method>get_wan_configs</obj_me
thod></param></RGW>

较get请求而言，主要是除了Header外还需要post数据。
