急！CHttpFile接收不到返回消息?

[sikivitas]

用CHttpFile向服务器上传文件，服务器显示已经成功上传，并且发送了返回信息，但是CHttpFile就是收不到返回信息
以下为源码：

USES_CONVERSION;
CInternetSession Session;
CHttpConnection *pHttpConnection = NULL;
INTERNET_PORT nPort = 8080;
 CFile fTrack;
 CHttpFile* pHTTP;
 CString strHTTPBoundary = _T("BSQHttpBoundary");
 CString strPreFileData;
 CString strPostFileData;
 DWORD dwTotalRequestLength;
 DWORD dwChunkLength;
 DWORD dwReadLength;
 DWORD dwResponseLength;
 TCHAR szError[MAX_PATH];
 void* pBuf;
 LPSTR szResponse;
 CString strResponse;
 BOOL blnSuccess = TRUE;
 CString strDebugMessage;
 
 
 if (FALSE == fTrack.Open(strFilePath, CFile::modeRead | CFile::shareDenyWrite))
 {
	AfxMessageBox(_T("Unable to open the file."));
	return FALSE;
 }
 
 CString strFileName = strFilePath.Mid(strFilePath.ReverseFind('\\') + 1);
 strPreFileData = MakePreFileData(strHTTPBoundary, strFileName);
 strPostFileData = MakePostFileData(strHTTPBoundary);
 dwTotalRequestLength = strPreFileData.GetLength() + strPostFileData.GetLength() + fTrack.GetLength();
 
 dwChunkLength = 64 * 1024;
 
 pBuf = malloc(dwChunkLength);
 if (NULL == pBuf)
	return FALSE;
 
 try
 {
  pHttpConnection = Session.GetHttpConnection(defServerName,nPort);
  pHTTP = pHttpConnection->OpenRequest(CHttpConnection::HTTP_VERB_POST, defObjectName);
  pHTTP->AddRequestHeaders(MakeRequestHeaders(strHTTPBoundary));//"Content-Type: multipart/form-data; boundary=%s\r\n"
  pHTTP->SendRequestEx(dwTotalRequestLength, HSR_SYNC | HSR_INITIATE);
  
#ifdef _UNICODE
  pHTTP->Write(W2A(strPreFileData), strPreFileData.GetLength());
#else
  pHTTP->Write((LPSTR)(LPCSTR)strPreFileData, strPreFileData.GetLength());
#endif
  
	dwReadLength = -1;
	while (0 != dwReadLength)
	{
		strDebugMessage.Format(_T("%u / %u\n"), fTrack.GetPosition(), fTrack.GetLength());
		TRACE(strDebugMessage);
		dwReadLength = fTrack.Read(pBuf, dwChunkLength);
		if (0 != dwReadLength)
			pHTTP->Write(pBuf, dwReadLength);
	}
  
#ifdef _UNICODE
  pHTTP->Write(W2A(strPostFileData), strPostFileData.GetLength());
#else
  pHTTP->Write((LPSTR)(LPCSTR)strPostFileData, strPostFileData.GetLength());
#endif
  
  pHTTP->EndRequest(HSR_SYNC);
  
  dwResponseLength = pHTTP->GetLength();      <-- 这里一直都是“0”
  while (0 != dwResponseLength)
  {
   szResponse = (LPSTR)malloc(dwResponseLength + 1);
   szResponse[dwResponseLength] = '\0';
   pHTTP->Read(szResponse, dwResponseLength);
   strResponse += szResponse;
   free(szResponse);
   dwResponseLength = pHTTP->GetLength();
  }
  
  AfxMessageBox(strResponse);
  
 }
 
 catch (CException* e)
 {
  e->GetErrorMessage(szError, MAX_PATH);
  e->Delete();
  AfxMessageBox(szError);
  blnSuccess = FALSE;
 }
 
 pHTTP->Close();
 delete pHTTP;
 
 fTrack.Close();
 
 if (NULL != pBuf)
 {
  free(pBuf);
 }
 
 return blnSuccess;

CHttpFile::QueryInfo()
CHttpFile::QueryInfoStatusCode();
查询一下信息和状态码

[sikivitas]

查询状态都是正常的，而且服务器也都收到了

[sikivitas]

服务器用的是java，下面是片段：

private void writeXmlToResp(HttpServletResponse resp,String xml)
{
try{
resp.setContentType("text/html;charset=GBK");
resp.setHeader("Cache-Control","no-cache");
   PrintWriter out=resp.getWriter();
   out.write(xml);
   out.flush();
   out.close();
}catch(Exception e){e.printStackTrace();}
}

CHttpFile::QueryInfo()
CHttpFile::QueryInfoStatusCode();

[/Quote]

用QueryInfo查询出的返回信息长度一直是0，内容是空的
QueryInfoStatusCode返回的是200，正常的


奇怪的是，用asp.net写的服务器就能收到正常信息，而那个java就是收不到
asp写的内容为：

<%
Response.ContentType = "text/html;charset=GBK"
Response.CacheControl = "no-cache"
If Request.Form("recordid") <> "" Then
Response.Write(1)
Else
Response.Write(2)
End If
response.End()
%>
