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 InternetQueryDataAvailablelpszData = 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 bufferlpszData[dwDownloaded]='/0';int nLen = m_editContentGot.GetWindowTextLength();m_editContentGot.SetSel(nLen-1, nLen-1);m_editContentGot.ReplaceSel(lpszData);// Delete the two buffersdelete[] lpszData;// Check the size of the remaining data. If it is zero, break.if (dwDownloaded == 0)break;}}}// Close the HINTERNET handleInternetCloseHandle(hRequest);InternetCloseHandle(hSession);InternetCloseHandle(hInternet);// Set the cursor back to an arrowSetCursor(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}
