我怎样才能获得的CookieContainer的所有Cookie吗?(How can I get a

2019-08-22 14:35发布

我想用一个Newtonsoft.Json到的CookieContainer导出到JSON可惜的CookieContainer具有不枚举或东西,所以我无法通过它循环...

编辑:随着我发布的解决方案,将是这样的:

private static void Main(string[] args)
{
    CookieContainer cookieContainer = new CookieContainer();
    cookieContainer.Add(new Cookie("name1", "value1", "/", ".testdomain1.com"));
    cookieContainer.Add(new Cookie("name2", "value1", "/path1/", ".testdomain1.com"));
    cookieContainer.Add(new Cookie("name2", "value1", "/path1/path2/", ".testdomain1.com"));
    cookieContainer.Add(new Cookie("name1", "value1", "/", ".testdomain2.com"));
    cookieContainer.Add(new Cookie("name2", "value1", "/path1/", ".testdomain2.com"));
    cookieContainer.Add(new Cookie("name2", "value1", "/path1/path2/", ".testdomain2.com"));

    CookieCollection cookies = GetAllCookies(cookieContainer);

    Console.WriteLine(JsonConvert.SerializeObject(cookies, Formatting.Indented));
    Console.Read();
}

Answer 1:

使用反射的溶液:

public static CookieCollection GetAllCookies(CookieContainer cookieJar)
{
    CookieCollection cookieCollection = new CookieCollection();

    Hashtable table = (Hashtable) cookieJar.GetType().InvokeMember("m_domainTable",
                                                                    BindingFlags.NonPublic |
                                                                    BindingFlags.GetField |
                                                                    BindingFlags.Instance,
                                                                    null,
                                                                    cookieJar,
                                                                    new object[] {});

    foreach (var tableKey in table.Keys)
    {
        String str_tableKey = (string) tableKey;

        if (str_tableKey[0] == '.')
        {
            str_tableKey = str_tableKey.Substring(1);
        }

        SortedList list = (SortedList) table[tableKey].GetType().InvokeMember("m_list",
                                                                    BindingFlags.NonPublic |
                                                                    BindingFlags.GetField |
                                                                    BindingFlags.Instance,
                                                                    null,
                                                                    table[tableKey],
                                                                    new object[] { });

        foreach (var listKey in list.Keys)
        {
            String url = "https://" + str_tableKey + (string) listKey;
            cookieCollection.Add(cookieJar.GetCookies(new Uri(url)));
        }
    }

    return cookieCollection;
}


Answer 2:

第一个答案没有为便携式项目。 因此,这里的选项2,还采用了反射

using System.Linq;
using System.Collections;
using System.Reflection;
using System.Net;

    public static CookieCollection GetAllCookies(this CookieContainer container)
    {
        var allCookies = new CookieCollection();
        var domainTableField = container.GetType().GetRuntimeFields().FirstOrDefault(x => x.Name == "m_domainTable");            
        var domains = (IDictionary)domainTableField.GetValue(container);

        foreach (var val in domains.Values)
        {
            var type = val.GetType().GetRuntimeFields().First(x => x.Name == "m_list");
            var values = (IDictionary)type.GetValue(val);
            foreach (CookieCollection cookies in values.Values)
            {
                allCookies.Add(cookies);                    
            }
        }          
        return allCookies;
    }

1)I也尝试

var domainTableField = container.GetType().GetRuntimeField("m_domainTable"); 

但它返回null。

2)您可以通过所有密钥domains.Keys和使用container.GetCookies()迭代。 但我已经与问题,因为预计的getCookies开放的,而不是我的所有钥匙匹配URI模式。



Answer 3:

这种方法将确保获得所有的cookies,无论该协议是什么:

public static IEnumerable<Cookie> GetAllCookies(this CookieContainer c)
{
    Hashtable k = (Hashtable)c.GetType().GetField("m_domainTable", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(c);
    foreach (DictionaryEntry element in k)
    {
        SortedList l = (SortedList)element.Value.GetType().GetField("m_list", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(element.Value);
        foreach (var e in l)
        {
            var cl = (CookieCollection)((DictionaryEntry)e).Value;
            foreach (Cookie fc in cl)
            {
                yield return fc;
            }
        }
    }
}


Answer 4:

使用CookieContainer.GetCookies方法

CookieCollection cookies = cookieContainer.GetCookies(new Uri(url));

这里url是您的网站的网址。

就我而言,我是不能够使用反射,在其他的答案建议。 不过,我也知道我的网站来查询的URL。 我认为这是合乎逻辑的,即使该容器未返回所有Cookie盲目,但返回他们每个URL,因为饼干永远属于一个特定的URL,不能与它们相关联的域的上下文之外使用。
