GetHttpConnection API抛出“操作超时”例外。？

问题描述

当我在c ++程序中使用GetHttpsConnection API时，我得到一个异常（CInternetException）操作超时。我不知道它的原因。任何人都可以帮助我吗？

代码部分：

 CInternetSession oInternetSession（_T（ 看门狗））; 
 UINT nBytesRead; 
 CHttpConnection * pConnection = NULL; 
 CHttpFile * pHttpFile = NULL; 
 CString strUserName = _T（ ）; 
 CString strPassword = _T（ ）; 
 DWORD dwStatusCode; 
  char  * chBuffer =  new   char  [ 1024 ]; 
 CString strLog; 
 
  try  
 {
 pConnection = oInternetSession.GetHttpConnection（m_strHttpServer，
（INTERNET_PORT）m_nHttpPort，strUserName ，strPassword）; 
 
  //  打开请求并获取HttpFile  
 pHttpFile = pConnection-> OpenRequest（ 1 ，m_strHttpObjectName，NULL， 1 ，NULL，NULL，INTERNET_FLAG_RELOAD）; 
  //  发送请求 
 pHttpFile-> SendRequest（）; 
} 
  catch （CInternetException * pe）
 {
 TCHAR ExcText [ 1024 ]; 
 pe-> GetErrorMessage（ExcText， 1023 ）; 
 TRACE（_T（  WinInet异常％s \ n），ExcText）; 
 strLog.Format（_T（ 访问网址：％s：％d /％s失败。原因： ％s），m_strHttpServer，m_nHttpPort，m_strHttpObjectName，ExcText）; 
 m_pLogger-> Log（LOGPRIO_HIGH，strLog）; 
 pe->删除（）; 
} 

谢谢。

When i am using GetHttpsConnection API in a c++ program, i got an exception(CInternetException) "The operation timed out". I don't know the reason for it. Can anyone help me?
code section:

	CInternetSession	oInternetSession(_T("Watchdog"));
	UINT				nBytesRead ;
	CHttpConnection*    pConnection	= NULL;
	CHttpFile*          pHttpFile	= NULL;
	CString             strUserName = _T("");
	CString             strPassword = _T("");
	DWORD               dwStatusCode;
	char*               chBuffer    = new char[1024];
	CString             strLog;

	try 
	{
		pConnection = oInternetSession.GetHttpConnection(m_strHttpServer, 
		(INTERNET_PORT) m_nHttpPort, strUserName, strPassword);

		//Open Request and get the HttpFile
		pHttpFile   = pConnection->OpenRequest(1, m_strHttpObjectName ,NULL, 1, NULL,   NULL,INTERNET_FLAG_RELOAD); 
		//Send Request
		pHttpFile->SendRequest();
}
catch(CInternetException* pe)
{
	TCHAR ExcText[1024];
	pe->GetErrorMessage(ExcText, 1023);
	TRACE(_T("WinInet exception %s\n"), ExcText);
	strLog.Format(_T("Accessing Url: %s:%d/%s failed. Reason: %s"), m_strHttpServer,m_nHttpPort, m_strHttpObjectName, ExcText);
	m_pLogger->Log(LOGPRIO_HIGH, strLog);
	pe->Delete();
}

Thanks.
