为这点小事也能郁闷。。

注意参数：

WideCharToMultiByte(CP_UTF8, 0, pszValue, -1, buf, 255, NULL, NULL );

BOOL result = FALSE;
CInternetSession session;
CHttpFile* pFile;
CHttpConnection* pConnection;
try
{
  char strUtf8Req[512];
  memset( strUtf8Req, 0, 512);
  WCHAR* strWchar;
  strWchar = request.GetBuffer();
  string str;
  GetAnsiString( str, strWchar);
  strcpy( strUtf8Req, str.c_str() );

  CString strServerName = _T("a.b.c.d:8080");
  CString strFormAction = _T("/xx/api/xxxxx");
  CString strHeaders    = _T("Content-Type: application/x-www-form-urlencoded");

  pConnection = session.GetHttpConnection(strServerName);
  if( pConnection == NULL)
   return FALSE;
  pFile = pConnection->OpenRequest(CHttpConnection::HTTP_VERB_POST, strFormAction);
  if( pFile == NULL)
   return FALSE;

  //result = pFile->SendRequest( strHeaders, (void*)strFormData, strlen(strFormData) );
  result = pFile->SendRequest( strHeaders, (void*)strUtf8Req, strlen(strUtf8Req) );
  DWORD dwRet;
  pFile->QueryInfoStatusCode(dwRet);
  if( dwRet == HTTP_STATUS_OK)
  {
   CString responseUtf8;
   CString strLine;
   while(pFile->ReadString(strLine))
   {
    responseUtf8 += strLine;
   }

   char* strUtf8 = (char*)responseUtf8.GetBuffer();
   result = ParseResponse(strUtf8, response);
   responseUtf8.ReleaseBuffer();
  }
  pFile->Close();
  session.Close();
  pConnection->Close();
    }
    catch (CInternetException* e)
{
  pFile->Close();
  session.Close();
  pConnection->Close();
        CString s;
        s.Format(_T("Internet Exception/r/nm_dwError%u,m_dwContextError%u"),e->m_dwError,e->m_dwContext);
        AfxMessageBox(s);
  return FALSE;
    }

return result;
