在vc中如何用post方法提交表单

我这里有一段程序，用来在一个对话框里显示出一次http request的原始信息，不过使用Inet API做的，希望能有帮助。

// Allocates a buffer of the size returned by InternetQueryDataAvailable
lpszData = new char[dwSize+1];

// Reads the data from the HINTERNET handle.
if(!InternetReadFile(hRequest,(LPVOID)lpszData,dwSize,&dwDownloaded))
{
delete[] lpszData;
break;
}
else
{
// Adds a null terminator to the end of the data buffer
lpszData[dwDownloaded]='\0';

int nLen = m_editContentGot.GetWindowTextLength();
m_editContentGot.SetSel(nLen-1, nLen-1);
m_editContentGot.ReplaceSel(lpszData);

// Delete the two buffers
delete[] lpszData;

// Check the size of the remaining data. If it is zero, break.
if (dwDownloaded == 0)
break;
}
}
}

// Close the HINTERNET handle
InternetCloseHandle(hRequest);
InternetCloseHandle(hSession);
InternetCloseHandle(hInternet);

// Set the cursor back to an arrow
SetCursor(LoadCursor(NULL,IDC_ARROW));

使用MFC示例如下:
首先设置m_strRequest请求字符串 eg."name=aaa&pass=bbb";
m_strServerName 服务器名称或者IP eg."www.yahoo.com"
m_strObjectName 请求文件位置 eg. "pub/aaa.asp"
请求的结果存放在m_strHtml中

func(){
CInternetSession m_InetSession("session");
CHttpConnection* pServer = NULL;
CHttpFile* pFile = NULL;
try{
INTERNET_PORT nPort;
nPort=80;
pServer = m_InetSession.GetHttpConnection(m_strServerName, nPort);
pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,
m_strObjectName);
char szHeaders[100];
strcpy(szHeaders,"Accept: text*/*\r\nContent-Type: application/x-www-form-urlencoded");
pFile->AddRequestHeaders(szHeaders);


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
}
