我可以通过Internet Explorer 11中运行的ActiveX内的I
HTMLDocument2 :: cookie访问标记为HttpOnly的会话cookie吗?以下是来自
the answer to this question的代码示例:
CComPtr<IHTMLDocument2> pDoc // get document from event as shown in the sample.
// read the cookie
CComBSTR cookie;
hr = pDoc->get_cookie(&cookie);
如果这是不可能通过IHTMLDocument2有没有任何其他方式来访问在ActiveX内部的IE中打开的网站的所有cookie?
最佳答案 无法使用文档对象读取cookie.因此,您需要在浏览器的上下文之外读取cookie.有一个SO线程解释了如何做同样的事情
Retrieve ALL cookies from Internet Explorer
以下是VBA代码,供答案参考

当然,如果要在VC代码中使用它,则需要将其移植到VC代码中
