VC获取cookies的几种方法

方法一:

CInternetSession::GetCookie

This member function implements the behavior of the Win32 function InternetGetCookie, as
described in the Windows SDK.

static BOOL GetCookie( 
   LPCTSTR pstrUrl, 
   LPCTSTR pstrCookieName, 
   LPTSTR pstrCookieData, 
   DWORD dwBufLen 
); 
static BOOL GetCookie( 
   LPCTSTR pstrUrl, 
   LPCTSTR pstrCookieName, 
   CString& strCookieData 
);

实现：

char * pszURL = "http://www.baidu.com/";
	CInternetSession::GetCookie(pszURL, "", strCookie);
	printf("%s\n", strCookie);

方法二:

InternetGetCookie

C++

BOOL InternetGetCookie(
  _In_     LPCTSTR lpszUrl,
  _In_     LPCTSTR lpszCookieName,
  _Out_    LPTSTR lpszCookieData,
  _Inout_  LPDWORD lpdwSize
);

http://msdn.microsoft.com/en-us/library/ie/aa384710(v=vs.85).aspx

实现:

LPDWORD lpdwSize = new DWORD;
	char strCookie_two[100] = {0};
	InternetGetCookie(pszURL, NULL, strCookie_two, lpdwSize);
	InternetGetCookie(pszURL, NULL, strCookie_two, lpdwSize);
	printf("%s\n", strCookie_two);

方法三:

QueryInfo

	CInternetSession session("HttpClient");
	CHttpFile* pfile = (CHttpFile *)session.OpenURL(pszURL);
	CString strCookie_three;
	pfile->QueryInfo(HTTP_QUERY_SET_COOKIE, strCookie_three);
	printf("%s\n", strCookie_three);
