c# - 如何获取 CookieContainer 的所有 Cookie？

Question

我想使用 Newtonsoft.Json 将 CookieContainer 导出到 JSON，但不幸的是 CookieContainer 没有枚举器或其他东西，所以我无法循环使用它......

编辑:使用我发布的解决方案，它会是这样的:

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

使用反射的解决方案:

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;
}

.NET 6 更新

最后，.NET 6 发布并引入了提取 CookieCollection 的 CookieContainer.GetAllCookies() 方法 - Documentation link .

public System.Net.CookieCollection GetAllCookies();
