如何在CookieContainer中获取cookie信息？ （所有这些，不是针对特定领域）

请参阅以下代码：

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获取cookie信息？ （所有这些，不仅仅针对特定领域。）
我怎样才能添加或删除cookie呢？

Answer 1

reflection可用于获取包含CookieContainer对象中所有域密钥的私有字段，

问：我如何得到私人领域的名称？

答。 使用reflection器;

它被声明为：

 private Hashtable m_domainTable; 

一旦我们获得私有字段，我们将获得域密钥，然后获取cookie是一个简单的迭代。

 using System; using System.Collections.Generic; using System.Linq; using System.Reflection; using System.Net; using System.Collections; namespace ConsoleApplication4 { static class Program { private static void Main() { CookieContainer cookies = new CookieContainer(); cookies.Add(new Cookie("name1", "value1", "/", "domain1.com")); cookies.Add(new Cookie("name2", "value2", "/", "domain2.com")); Hashtable table = (Hashtable) cookies.GetType().InvokeMember("m_domainTable", BindingFlags.NonPublic | BindingFlags.GetField | BindingFlags.Instance, null, cookies, new object[] { }); foreach (var key in table.Keys) { foreach (Cookie cookie in cookies.GetCookies(new Uri(string.Format("http://{0}/", key)))) { Console.WriteLine("Name = {0} ; Value = {1} ; Domain = {2}", cookie.Name, cookie.Value, cookie.Domain); } } Console.Read(); } } } 

Answer 2

感谢AppDeveloper的回答，这是一个稍微修改过的版本作为扩展方法。

 using System; using System.Collections; using System.Collections.Generic; using System.Linq; using System.Net; using System.Reflection; using System.Text; public static class CookieContainerExtension { public static List List(this CookieContainer container) { var cookies = new List(); var table = (Hashtable)container.GetType().InvokeMember("m_domainTable", BindingFlags.NonPublic | BindingFlags.GetField | BindingFlags.Instance, null, container, new object[] { }); foreach (var key in table.Keys) { Uri uri = null; var domain = key as string; if (domain == null) continue; if (domain.StartsWith(".")) domain = domain.Substring(1); var address = string.Format("http://{0}/", domain); if (Uri.TryCreate(address, UriKind.RelativeOrAbsolute, out uri) == false) continue; foreach (Cookie cookie in container.GetCookies(uri)) { cookies.Add(cookie); } } return cookies; } } 

要获取列表，只需在CookieContainer上调用List（）：

 CookieContainer cookies = new CookieContainer(); cookies.Add(new Cookie("name1", "value1", "/", "www.domain1.com")); cookies.Add(new Cookie("name2", "value2", "/", "www.domain2.com")); List cookieList = cookies.List(); 

Answer 3

改进版PaRiMal RaJ的代码。 此方法将打印http和https cookie。 准备将它粘贴到你的课堂上。

  // Paste this dependencies in your class using System; using System.Net; using System.Linq; using System.Reflection; using System.Collections; using System.Collections.Generic; /// 
 /// It prints all cookies in a CookieContainer. Only for testing. /// 
 /// A cookie container public void PrintCookies (CookieContainer cookieJar) { try { Hashtable table = (Hashtable) cookieJar .GetType().InvokeMember("m_domainTable", BindingFlags.NonPublic | BindingFlags.GetField | BindingFlags.Instance, null, cookieJar, new object[] {}); foreach (var key in table.Keys) { // Look for http cookies. if (cookieJar.GetCookies( new Uri(string.Format("http://{0}/", key))).Count > 0) { Console.WriteLine(cookieJar.Count+" HTTP COOKIES FOUND:"); Console.WriteLine("----------------------------------"); foreach (Cookie cookie in cookieJar.GetCookies( new Uri(string.Format("http://{0}/", key)))) { Console.WriteLine( "Name = {0} ; Value = {1} ; Domain = {2}", cookie.Name, cookie.Value,cookie.Domain); } } // Look for https cookies if (cookieJar.GetCookies( new Uri(string.Format("https://{0}/", key))).Count > 0) { Console.WriteLine(cookieJar.Count+" HTTPS COOKIES FOUND:"); Console.WriteLine("----------------------------------"); foreach (Cookie cookie in cookieJar.GetCookies( new Uri(string.Format("https://{0}/", key)))) { Console.WriteLine( "Name = {0} ; Value = {1} ; Domain = {2}", cookie.Name, cookie.Value,cookie.Domain); } } } } catch(Exception e) { Console.WriteLine (e); } } 

Answer 4

这些答案都不适合我。 这是我解决问题的简单方法。

 public static List List(this CookieContainer container) { var cookies = new List(); var table = (Hashtable)container.GetType().InvokeMember("m_domainTable", BindingFlags.NonPublic | BindingFlags.GetField | BindingFlags.Instance, null, container, null); foreach (string key in table.Keys) { var item = table[key]; var items = (ICollection) item.GetType().GetProperty("Values").GetGetMethod().Invoke(item, null); foreach (CookieCollection cc in items) { foreach (Cookie cookie in cc) { cookies.Add(cookie); } } } return cookies; } 

Answer 5

如果您要编写nUnit测试，它将是这样的：

  [Test] public void Test() { CookieContainer cookies = new CookieContainer(); cookies.Add(new Cookie("name1", "value1", "/", "www.domain1.com")); cookies.Add(new Cookie("name2", "value2", "/", "www.domain2.com")); Hashtable table = (Hashtable)cookies.GetType().InvokeMember("m_domainTable", BindingFlags.NonPublic | BindingFlags.GetField | BindingFlags.Instance, null, cookies, new object[] { }); foreach (var key in table.Keys) { foreach (Cookie cookie in cookies.GetCookies(new Uri(string.Format("http://{0}/", key.ToString().Substring(1,key.ToString().Length - 1))))) { Assert.That(cookie != null); //Console.WriteLine("Name = {0} ; Value = {1} ; Domain = {2}", cookie.Name, cookie.Value, // cookie.Domain); } } } 

Answer 6

这是一个扩展，结合了antfx的代码和Adrian Lopez使用http和https的想法。 对于可能发现有用的人来说，只需快速解决问题：

 public static class CookieContainerExtensions { public static List List(this CookieContainer container) { var cookies = new List(); var table = (Hashtable)container.GetType().InvokeMember("m_domainTable", BindingFlags.NonPublic | BindingFlags.GetField | BindingFlags.Instance, null, container, new object[] { }); foreach (var key in table.Keys) { var domain = key as string; if (domain == null) continue; if (domain.StartsWith(".")) domain = domain.Substring(1); var httpAddress = string.Format("http://{0}/", domain); var httpsAddress = string.Format("https://{0}/", domain); if (Uri.TryCreate(httpAddress, UriKind.RelativeOrAbsolute, out var httpUri)) { foreach (Cookie cookie in container.GetCookies(httpUri)) { cookies.Add(cookie); } } if (Uri.TryCreate(httpsAddress, UriKind.RelativeOrAbsolute, out var httpsUri)) { foreach (Cookie cookie in container.GetCookies(httpsUri)) { cookies.Add(cookie); } } } return cookies; } }
