然后是cpp文件





#include "StdAfx.h"

#include ".\uploadfile.h"

{

}

{

}



BOOL UpLoadFile::UseHttpSendReqEx(CHttpFile* httpFile, DWORD dwPostSize,CString strLocalFile)

{

try

{

return FALSE;

}



fclose(fLocal);

free(buffer);

return TRUE;

}

catch (CInternetException* pEx)

{

//catch errors from WinInet

}

return FALSE;

}





BOOL UpLoadFile::Upload(CString strLocalFile,CString strServerIP,CString strServerPort,CString strRemoteFile)

{

try

return TRUE;

}



httpFile->Close();

httpConnection->Close();

}

catch (CInternetException* pEx)

ZT:
下面是我写的一个类，用http put协议上传文件的
首先是头文件



#pragma once

#include <afxinet.h>



class UpLoadFile

{

public:

UpLoadFile(void);

~UpLoadFile(void);



BOOL Upload(CString strLocalFile,CString strServerIP,CString strServerPort,CString strRemoteFile);

private:

BOOL UseHttpSendReqEx(CHttpFile* httpFile,DWORD dwPostSize,CString strLocalFile);

};
