从网上下载了一个类,实现http post get 功能,但是一个头文件不知道是什么
以下是两个文件:HttpClient.h HttpClient.cpp 一个类
(错误检测部分没有加入)
使用方法
1:get方式
CHttpClient conn;
CString value= "http://8crystal.com/test.asp ";
value=conn.doGet(value);
2:post方式
CHttpClient conn;
CString value= "http://8crystal.com/test.asp ";
conn.addParam( "name1 ", "value1 ");
conn.addParam( "name2 ", "value2 ");
conn.addParam( "name3 ", "value3 ");
conn.addParam( "name4 ", "value4 ");
conn.addParam( "name5 ", "value5 ");
conn.addParam( "name6 ", "value6 ");
value=conn.doPost(value);

其中一个头文件#include "emailsenderv2.h " 是什么意思?
