VC 向web post数据
请教一下，VC 向web post数据

哪位能讲一下，或者有例子

CInternetSession m_InetSession(_T("session"),0,INTERNET_OPEN_TYPE_PRECONFIG,NULL,NULL,INTERNET_FLAG_DONT_CACHE);
CHttpConnection *pServer = NULL;
CHttpFile* pFile = NULL;
INTERNET_PORT port =8001;
try
{
pServer = m_InetSession.GetHttpConnection("127.0.0.1",port);
pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,"/");
CString strHeaders = "Accept: */*\r\nReferer: http://www.goodwaiter.com/\r\nAccept-Language: zh-cn\r\nContent-Type: application/x-www-form-urlencoded\r\nAccept-Encoding: gzip, deflate\r\nUser-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Maxthon; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";
pFile->AddRequestHeaders(strHeaders);

pFile->SendRequestEx(m_strRequest.GetLength());
pFile->WriteString(m_strRequest);//重要-->m_Request 中有"name=aaa&name2=BBB&"
pFile->EndRequest();
/*DWORD dwRet;
pFile->QueryInfoStatusCode(dwRet);
CString str;

m_Mutex.Lock();
m_strHtml="";
char szBuff[1024];

if (dwRet == HTTP_STATUS_OK)
{
UINT nRead;
while ((nRead = pFile->Read(szBuff,1023))>0)
{
m_strHtml += CString(szBuff,nRead);
}
}
m_Mutex.Unlock();

delete pFile;
delete pServer; */
}
catch (CInternetException* e)
{
CString s;
s.Format("Internet Exception\r\nm_dwError%u,m_dwContextError%u",e->m_dwError,e->m_dwContext);
AfxMessageBox(s);
//catch errors from WinInet
}

这是我找到的，
pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,"/");
pFile->WriteString(m_strRequest);//重要-->m_Request 中有"name=aaa&name2=BBB&"

这两句里面的参数不是很清楚："/" m_strRequest
