如何安装和配置阿帕奇服务器

请参考：<?php//$file = $_GET['filename'];//file_put_contents("aaa.txt", var_export($file,true));file_put_contents("abb.txt", var_export($_FILES,true)); upload_file();function upload_file(){$error;if ($_FILES["trackdata"]["error"] > 0) { //echo "Error: " . $_FILES["trackdata"]["error"] . " "; $error = "200"; } else { //echo "Upload: " . $_FILES["trackdata"]["name"] . " "; //echo "Type: " . $_FILES["trackdata"]["type"] . " "; //echo "Size: " . ($_FILES["trackdata"]["size"] / 1024) . " Kb "; //echo "Stored in: " . $_FILES["trackdata"]["tmp_name"]. " " ; } if (file_exists("upload/" . $_FILES["trackdata"]["name"])) { //echo $_FILES["trackdata"]["name"] . " already exists. "; $error = "201"; } else { move_uploaded_file($_FILES["trackdata"]["tmp_name"],"upload/" . $_FILES["trackdata"]["name"]); //echo "Stored in: " . "upload/" . $_FILES["trackdata"]["name"]; $error = 202; } echo $error ; return $error;} ?>

这个代码比较基本，也就是一个demo，不过还是要感谢北京做php的那个哥们的热心帮助。

c++客户端程序

先上代码：

1.请求消息头函数：

CString CDlgUpFile::MakeRequestHeaders1(CString& strBoundary){CString strFormat;CString strData;strFormat = _T("Content-Type: multipart/form-data; boundary=%s\r\n");strData.Format(strFormat, strBoundary);return strData;}

2.数据头函数：

CString CDlgUpFile::MakePreFileData1(CString& strBoundary, CString& strFileName, int iRecordID){CString strFormat;CString strData;strFormat += _T("--%s");strFormat += _T("\r\n");strFormat += _T("Content-Disposition: form-data; name=\"recordid\"");strFormat += _T("\r\n\r\n");strFormat += _T("%d");strFormat += _T("\r\n");strFormat += _T("--%s");strFormat += _T("\r\n");strFormat += _T("Content-Disposition: form-data; name=\"trackdata\"; filename=\"%s\"");strFormat += _T("\r\n");//strFormat += _T("Content-Type: audio/wav");strFormat += _T("Content-Type: application/x-www-form-urlencoded");strFormat += _T("\r\n");strFormat += _T("Content-Transfer-Encoding: binary");strFormat += _T("\r\n\r\n");strData.Format(strFormat, strBoundary, iRecordID, strBoundary, strFileName);return strData;}

3.数据结束函数：

CString CDlgUpFile::MakePostFileData1(CString& strBoundary){CString strFormat;CString strData;strFormat = _T("\r\n");strFormat += _T("--%s");strFormat += _T("\r\n");strFormat += _T("Content-Disposition: form-data; name=\"submitted\"");strFormat += _T("\r\n\r\n");strFormat += _T("hello");strFormat += _T("\r\n");strFormat += _T("--%s--");strFormat += _T("\r\n");strData.Format(strFormat, strBoundary, strBoundary);return strData;}

4.上传函数：

//上传文件数据至HTTP服务器int CDlgUpFile::UploadFile1(const CString &szServerURL, const CString &szUploadFileName,CString &szRecvData){if (szServerURL.IsEmpty() || szUploadFileName.IsEmpty()){return -1;}BOOL bRet = FALSE;DWORD dwServiceType = 0; CString strServer = _T("");CString strObject = _T("");INTERNET_PORT nPort = 0;bRet =  AfxParseURL(szServerURL, dwServiceType, strServer, strObject, nPort);if(!bRet){return -2;}int nRet = 0;CInternetSession Session;CHttpConnection * pHttpConnection = NULL;CFile fTrack;CHttpFile* pHTTPFile = NULL;CString strHTTPBoundary = _T("");CString strPreFileData = _T("");CString strPostFileData = _T("");DWORD dwTotalRequestLength;DWORD dwChunkLength = 0;DWORD dwReadLength = 0;DWORD dwResponseLength = 0;TCHAR szError[MAX_PATH] = {0};void* pBuffer = NULL;LPSTR szResponse = NULL;CString strResponse = _T("");BOOL bSuccess = TRUE;CString strDebugMessage = _T("");if (FALSE == fTrack.Open(szUploadFileName, CFile::modeRead | CFile::shareDenyWrite)){//AfxMessageBox(_T("Unable to open the file."));return -3;}int nPos = szUploadFileName.ReverseFind('\\');CString strFileName = szUploadFileName.Mid(nPos+1);//不带路径的文件名int iRecordID = 1;strHTTPBoundary = _T("----istroop----");strPreFileData = MakePreFileData1(strHTTPBoundary, strFileName, iRecordID);strPostFileData = MakePostFileData1(strHTTPBoundary);m_dwFileSize = fTrack.GetLength();dwTotalRequestLength = strPreFileData.GetLength() + strPostFileData.GetLength() + m_dwFileSize;dwChunkLength = 64 * 1024;pBuffer = malloc(dwChunkLength);if (NULL == pBuffer){fTrack.Close();return -4;}try{pHttpConnection = Session.GetHttpConnection(strServer,nPort);pHTTPFile = pHttpConnection->OpenRequest(CHttpConnection::HTTP_VERB_POST, strObject);pHTTPFile->AddRequestHeaders(MakeRequestHeaders1(strHTTPBoundary));pHTTPFile->SendRequestEx(dwTotalRequestLength, HSR_SYNC | HSR_INITIATE);#ifdef _UNICODEUSES_CONVERSION;pHTTPFile->Write(W2A(strPreFileData), strPreFileData.GetLength());#elsepHTTPFile->Write((LPSTR)(LPCSTR)strPreFileData, strPreFileData.GetLength());#endifdwReadLength = -1;m_dwUploadSize = 0;while (0 != dwReadLength){//  strDebugMessage.Format(_T("%u / %un"), fTrack.GetPosition(), fTrack.GetLength());//  TRACE(strDebugMessage);dwReadLength = fTrack.Read(pBuffer, dwChunkLength);if (0 != dwReadLength){m_dwUploadSize += dwReadLength;pHTTPFile->Write(pBuffer, dwReadLength);}}#ifdef _UNICODEpHTTPFile->Write(W2A(strPostFileData), strPostFileData.GetLength());#elsepHTTPFile->Write((LPSTR)(LPCSTR)strPostFileData, strPostFileData.GetLength());#endifpHTTPFile->EndRequest(HSR_SYNC);dwResponseLength = pHTTPFile->GetLength();while (0 != dwResponseLength){szResponse = (LPSTR)malloc(dwResponseLength + 1);szResponse[dwResponseLength] = '\0';pHTTPFile->Read(szResponse, dwResponseLength);strResponse += szResponse;free(szResponse);szResponse = NULL;dwResponseLength = pHTTPFile->GetLength();}szRecvData = strResponse;}catch (CException* e){//  e->GetErrorMessage(szError, MAX_PATH);//  e->Delete();nRet = -5;}if (NULL != pHTTPFile){pHTTPFile->Close();delete pHTTPFile;pHTTPFile = NULL;}fTrack.Close();if (NULL != pBuffer){free(pBuffer);pBuffer = NULL;}return nRet;}

代码分析

1.http协议部分

CInternetSession Session;CHttpConnection * pHttpConnection = NULL;CHttpFile* pHTTPFile = NULL;pHttpConnection = Session.GetHttpConnection(strServer,nPort);pHTTPFile = pHttpConnection->OpenRequest(CHttpConnection::HTTP_VERB_POST, strObject);pHTTPFile->AddRequestHeaders(MakeRequestHeaders1(strHTTPBoundary));pHTTPFile->SendRequestEx(dwTotalRequestLength, HSR_SYNC | HSR_INITIATE);

这里用到了CInternetSession、CHttpConnection、CHttpFile。

2.文件操作

用的是CFile fTrack;

3.数据传送

消息头：

pHTTPFile->AddRequestHeaders(MakeRequestHeaders1(strHTTPBoundary));

请求数据长度：
pHTTPFile->SendRequestEx(dwTotalRequestLength, HSR_SYNC | HSR_INITIATE);

数据头：

#ifdef _UNICODE
  USES_CONVERSION;
  pHTTPFile->Write(W2A(strPreFileData), strPreFileData.GetLength());
#else
  pHTTPFile->Write((LPSTR)(LPCSTR)strPreFileData, strPreFileData.GetLength());
#endif

文件数据，循环读取文件和发送：

   dwReadLength = fTrack.Read(pBuffer, dwChunkLength);
   if (0 != dwReadLength)
   {
    m_dwUploadSize += dwReadLength;
    pHTTPFile->Write(pBuffer, dwReadLength);
   }

文件结束：

#ifdef _UNICODE
pHTTPFile->Write(W2A(strPostFileData), strPostFileData.GetLength());
#else
pHTTPFile->Write((LPSTR)(LPCSTR)strPostFileData, strPostFileData.GetLength());
#endif
