设置代理后HttpSendRequest函数在Unicode环境下出错

[fffjjjhhh]

发现一个奇怪的问题，设置代理后HttpSendRequest函数在Unicode环境下出错，设置代理后HttpSendRequest函数在ANSI环境下可以使用。如果不设置代理的话HttpSendRequest一切正常，这是怎么回事，想请高手解答一下，我用的VS2010，而且必须用Unicode环境。以下为代码：

string CTestDlg::doGet1(CString   istrObjet)
{


	string sErrMg;
	string httpsource;
	BOOL b=TRUE;
	
	HINTERNET m_hConnection = InternetConnect(
		m_hInternet, 
		m_strServer,
		m_nPort, 
		NULL, 
		NULL,
		INTERNET_SERVICE_HTTP, 
		INTERNET_FLAG_NO_UI, 
		NULL);

	if (FALSE == m_hConnection)
	{
		InternetCloseHandle(m_hConnection);
		InternetCloseHandle(m_hInternet);
		sErrMg=_T("网络未连接上：建立网络连接失败");
		return sErrMg;
	}


	static LPCTSTR s_szAcceptTypes[] = { _T("*/*"), NULL };

	HINTERNET m_hRequest = HttpOpenRequest(
		m_hConnection, _T("GET"), 
		istrObjet, 
		_T("HTTP/1.0"), NULL,
		s_szAcceptTypes, 
		INTERNET_FLAG_NO_UI | INTERNET_FLAG_KEEP_CONNECTION, // | ((m_url.GetScheme() == ATL_URL_SCHEME_HTTPS) ? INTERNET_FLAG_SECURE : 0)
		NULL);
	if (FALSE == m_hRequest)
	{
		InternetCloseHandle(m_hRequest);
		InternetCloseHandle(m_hConnection);
		InternetCloseHandle(m_hInternet);
		sErrMg=_T("网络未连接上：打开网络连接失败");
		return sErrMg;
	}
	
	CString tAddHost;
	tAddHost=_T("Accept: application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*");
	HttpAddRequestHeaders(m_hRequest,tAddHost,tAddHost.GetLength( ),HTTP_ADDREQ_FLAG_ADD);
	
	
	tAddHost=_T("Accept-Language: zh-CN");
	HttpAddRequestHeaders(m_hRequest,tAddHost,tAddHost.GetLength( ),HTTP_ADDREQ_FLAG_ADD);
	
	
	tAddHost=_T("Accept-Encoding: gzip, deflate");
	HttpAddRequestHeaders(m_hRequest,tAddHost,tAddHost.GetLength( ),HTTP_ADDREQ_FLAG_ADD);
	
	tAddHost=_T("Connection: Keep-Alive");
	HttpAddRequestHeaders(m_hRequest,tAddHost,tAddHost.GetLength( ),HTTP_ADDREQ_FLAG_ADD);

	b = HttpSendRequest(m_hRequest, NULL, 0,		
		NULL, 0);

	if (FALSE == b)
	{
		InternetCloseHandle(m_hRequest);
		InternetCloseHandle(m_hConnection);
		InternetCloseHandle(m_hInternet);
		sErrMg=_T("网络未连接上：向服务器发送请求失败");
		return sErrMg;
	}


	TCHAR cookbuffer[512];


	DWORD TRF=512;
	DWORD TRF1=0;
	b=HttpQueryInfo(m_hRequest, HTTP_QUERY_SET_COOKIE, cookbuffer,
		&TRF,&TRF1);
	if(FALSE==b)
	{
		sErrMg=_T("网络未连接上：未获取COOKIE");
		
	}


//	int iStatus = GetInternetRequestStatusCode(m_hRequest);
	/*
	if(!(iStatus>= 200&& iStatus<300 ))
	{
		InternetCloseHandle(m_hRequest);
		InternetCloseHandle(m_hConnection);
		InternetCloseHandle(m_hInternet);
		sErrMg.Format(_T("网络未连接上：打开远程文件出错，错误码：%d"), iStatus);
		return FALSE;
	}*/

	byte pData[65535];
	DWORD dwReadedLen;
    DWORD dwWrittenLen;  

	while(1)
	{
		b =  InternetReadFile(m_hRequest, (LPVOID)pData, sizeof(pData), &dwReadedLen);
		if (b == FALSE)
		{
//			CloseHandle(hfile);
			InternetCloseHandle(m_hRequest);
			InternetCloseHandle(m_hConnection);
		//	InternetCloseHandle(m_hInternet);
			sErrMg=_T("网络未连接上：读取文件失败");
			return sErrMg;
		}
		if(dwReadedLen == 0)
		{
			break;  
		}
		pData[dwReadedLen]=0;
		httpsource+=(char*)pData;


	}

//	CloseHandle(hfile);
	InternetCloseHandle(m_hRequest);
	InternetCloseHandle(m_hConnection);
	//InternetCloseHandle(m_hInternet);
	return httpsource;

	
}

顶一下顶一下

那你改用后面带A的函数吧，比如HttpSendRequestA(...)这之类的

[fffjjjhhh]

错误代码为12029

[oyljerry]

The attempt to connect to the server failed. 估计还是参数有问题

[fffjjjhhh]

找到原因了,真的很无语 CString iDlText=_T("21.12.7.8"); char *strProxyList=UnicodeToGB2312(iDlText);//在Unicode环境下是加了这一句就好了 //LPCTSTR INTERNET_PROXY_INFO proxyinfo; proxyinfo.dwAccessType = INTERNET_OPEN_TYPE_PROXY; proxyinfo.lpszProxy=(LPCTSTR)strProxyList; proxyinfo.lpszProxyBypass = NULL; DWORD dwStatusCode; CString data; if(!SetOption(INTERNET_OPTION_PROXY,(LPVOID)&proxyinfo,sizeof(INTERNET_PROXY_INFO))) //设置代理服务器 { proxyinfo.dwAccessType=INTERNET_OPEN_TYPE_DIRECT; SetOption(INTERNET_OPTION_PROXY,(LPVOID)&proxyinfo,sizeof(INTERNET_PROXY_INFO)); return false; } 看了一下INTERNET_PROXY_INFO 的定义 typedef struct { // // dwAccessType - INTERNET_OPEN_TYPE_DIRECT, INTERNET_OPEN_TYPE_PROXY, or // INTERNET_OPEN_TYPE_PRECONFIG (set only) // DWORD dwAccessType; // // lpszProxy - proxy server list // LPCTSTR lpszProxy; // // lpszProxyBypass - proxy bypass list // LPCTSTR lpszProxyBypass; } INTERNET_PROXY_INFO, * LPINTERNET_PROXY_INFO; 这是InternetSetOption函数的定义,也是分A和W的,本来想着代理地址会自动区别A字符串和W字符串的,谁知根本没有任何区别,所以在Unicode环境下代理地址也只能用A字符串了,不知道这算不算微软的BUG,搞的我快崩溃了.看来还是用WINSOCK比较好.请大家发表一下意见就结贴. BOOLAPI InternetSetOptionA( __in_opt HINTERNET hInternet, __in DWORD dwOption, __in_opt LPVOID lpBuffer, __in DWORD dwBufferLength ); BOOLAPI InternetSetOptionW( __in_opt HINTERNET hInternet, __in DWORD dwOption, __in_opt LPVOID lpBuffer, __in DWORD dwBufferLength ); #ifdef UNICODE #define InternetSetOption InternetSetOptionW #else #define InternetSetOption InternetSetOptionA #endif // !UN

原来是这样写的,我就奇怪lpszProxy是ANSI字符,iDlText是Unicode字符,编译也不报错,在其它出地方出现这种情况会报错的,搞的我十几天找不到原因. CString iDlText=_T("21.12.7.8"); //LPCTSTR INTERNET_PROXY_INFO proxyinfo; proxyinfo.dwAccessType = INTERNET_OPEN_TYPE_PROXY; proxyinfo.lpszProxy=iDlText; proxyinfo.lpszProxyBypass = NULL; DWORD dwStatusCode; CString data; if(!SetOption(INTERNET_OPTION_PROXY,(LPVOID)&proxyinfo,sizeof(INTERNET_PROXY_INFO))) //设置代理服务器 { proxyinfo.dwAccessType=INTERNET_OPEN_TYPE_DIRECT; SetOption(INTERNET_OPTION_PROXY,(LPVOID)&proxyinfo,sizeof(INTERNET_PROXY_INFO)); return false; }

lz这个估计直接 CString iDlText=_T("21.12.7.8"); char *strProxyList=UnicodeToGB2312(iDlText);//在Unicode环境下是加了这一句就好了 ====> char *strProxyList="21.12.7.8"; 就可以
