CHttpConnection

1、构造一个CInternetSession的实例

CInternetSession*   pSession =new CinternetSession();//CInternetSession m_session;//类成员变量可不new

2、构造一个CHttpConnection对象

CHttpConnection*   pConnection=pSession->GetHttpConnection(csServerName);

        //csServerName 域名：如：www.baidu.com

3、打开HTTP连接

CHttpFile *   pHttpFile = pConnection->OpenRequest(CHttpConnection::HTTP_VERB_POST, csObjectName);

       //csObjectName网址的后面部分

4、发送数据

BOOL bresult =  pHttpFile->SendRequest(csHeaders,   (LPVOID)(LPCTSTR)pCharFormData,  strlen(pCharFormData));

5、可读取服务器返回的数据

char strReSult[1024];
memset(strReSult, 0, BUFFER_SIZE);
while (pHttpFile->Read(strReSult, 1023))

{

}

pHttpFile->Close();

pConnection->Close() ;

delete  pSession;
