如何获取 CookieContainer 内的 cookie 信息?(所有这些，不针对特定领域) [英] How to get cookies info inside of a CookieContainer? (All Of Them, Not For A Specific Domain)

问题描述

请看下面的代码:

CookieContainer cookieJar = new CookieContainer();
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://www.google.com");
request.CookieContainer = cookieJar;

HttpWebResponse response = (HttpWebResponse)request.GetResponse();
int cookieCount = cookieJar.Count;

如何在 cookieJar 中获取 cookie 信息?(所有这些，而不仅仅是针对特定域.)
以及如何从中添加或删除 cookie?

How can I get cookies info inside cookieJar? (All of them, not just for a specific domain.)
And how can I add or remove a cookie from that?

推荐答案

reflection 可用于获取保存 CookieContainer 对象中所有域键的私有字段，

reflection can be used to get the private field that holds all the domain key in CookieContainer object,

问.我如何获得该私有字段的名称?

答.使用反射器；

它被声明为:

private Hashtable m_domainTable;

一旦我们获得了私有字段，我们就会获得域密钥，然后获得 cookie 就是一个简单的迭代.

once we get the private field, we will get the the domain key, then getting cookies is a simple iteration.

            cookies.Add(new Cookie("name1", "value1", "/", "domain1.com"));
            cookies.Add(new Cookie("name2", "value2", "/", "domain2.com"));

            Hashtable table = (Hashtable)cookies.GetType().InvokeMember(
                "m_domainTable",

            {
                Uri uri = new Uri(string.Format("http://{0}/", key));

                foreach (Cookie cookie in cookies.GetCookies(uri))
                {
                    Console.WriteLine("Name = {0} ; Value = {1} ; Domain = {2}",
                        cookie.Name, cookie.Value, cookie.Domain);
