GSoap根据filename读取图片byte

_ns1__FileUpload request;
 request.fileNameGuid = &std::string(fileName.GetBuffer(0));
 CFile cfile;
 cfile.Open(fileName,CFile::modeRead|CFile::typeBinary);
 int dwLo=(int)cfile.GetLength();
 BYTE *pss=new BYTE[dwLo];
 ZeroMemory(pss,dwLo);
 cfile.Read(pss,dwLo);
 xsd__base64Binary photo;
 photo.__ptr=new BYTE[dwLo];
 memcpy(photo.__ptr,pss,dwLo);
 request.data = &photo;
 cfile.Close();
