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");
