3.文件上传
#include <afxinet.h>
int UploadFile(LPCTSTR strURL, //负责接收上传操作的页面的URL
    LPCTSTR strLocalFileName)  //待上传的本地文件路径

        file.Read(pFileBuff, dwFileLength);

        const int nTimeOut = 5000;
        cis.SetOption(INTERNET_OPTION_CONNECT_TIMEOUT, nTimeOut); //联接超时设置
        cis.SetOption(INTERNET_OPTION_CONNECT_RETRIES, 1);  //重试1次
        pHC = cis.GetHttpConnection(strServer, wPort);  //取得一个Http联接
