Как отправить Zip (двоичный) файл через HTTP post метод в mFC / C ++?

Question

Я отправляю файл на сервер, и он работает нормально, но мой код не работает, когда я пытаюсь опубликовать файл .zip. Возможно, мой код неверен при чтении данных содержимого zip-файла.

ifstream::pos_type size;
char * memblock;
ifstream file ("example.zip", ios::in|ios::binary|ios::ate);
if (file.is_open())
{
 size = file.tellg();
 memblock = new char [size];
 file.seekg (0, ios::beg);
 file.read (memblock, size);
 file.close();

 postBody.AppendFormat("Content-Disposition: form-data; name=\"datafile\"; filename=\"%s\"; \r\n\n%s", zipFilePath, memblock); 
 postBody.AppendFormat("\r\n--%s--\r\n", boundary);
}

Наконец я получил ответ на этот вопрос:

 CString boundary = "-------------------------------7d8b32060180";
          CString postBody(_T(""));
          postBody.AppendFormat("\r\n--%s\r\n", boundary);

          postBody.AppendFormat("Content-Disposition: form-data; name=\"name\"\n\n%s", name);
          postBody.AppendFormat("\n--%s\r\n", boundary);

          postBody.AppendFormat("Content-Disposition: form-data; name=\"email\"\n\n\n\r\r\n%s\n", emailID);
          postBody.AppendFormat("\r\n--%s\r\n", boundary);

          postBody.AppendFormat("Content-Disposition: form-data; name=\"comments\"\n\n\r\r\n%s\n", comment);
          postBody.AppendFormat("\r\n--%s\r\n", boundary);

          postBody.AppendFormat("Content-Disposition: form-data; name=\"subject\"\n\n\r\r\n%s\n", subjectLine);  
          postBody.AppendFormat("\r\n--%s\r\n", boundary);

          if (!filePath.IsEmpty())

          httpReqBodyLen = postBody.GetLength() + strlen("\n--" + boundary + "--\r\n") + fileBufLen + 1;
          httpRequestBody = new BYTE[httpReqBodyLen];  //create enough buffer memory
          memset(httpRequestBody, 0x00, httpReqBodyLen);
          memcpy(httpRequestBody, postBody.GetString(), postBody.GetLength()); //write header to final buffer
          if (!filePath.IsEmpty() && fileBuff)
          {
                memcpy(httpRequestBody + postBody.GetLength(), fileBuff, fileBufLen); //add file contents
                delete fileBuff;
          }

          memcpy(httpRequestBody + postBody.GetLength() + fileBufLen, _T("\n--" + boundary + "--\r\n"), strlen("\n--" +boundary+ "--\r\n")); 
          httpRequestBody[httpReqBodyLen - 1] = '\0';
