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
