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);
