Question

我在标题中有以下Cookie

Cookie：ASP.NET_SessionId = cm3bg4muwin1vmbovc1esjy3; HOST = SCANDICWEB101; ieAlertDisplay = TRUE; scandic_lb_cookie = 1702298890.0.0000; s_sv_sid = 110733906247;

这是我获得第一个

的代码

var sessionId = webResponse.Headers["Set-Cookie"].Split(';')
                   .First(s => s.StartsWith("ASP.NET_SessionId="));

我试图获得host，scandic_lb_cookie以及其余部分，但我无法找到一种方法来做到这一点，你能给我一些想法吗？

Answer 1

可能有更快的解决方案，但以下应该有效：

string source = cookie.Substring(8); // remove the "Cookie: "
var parts = source.Split(';')
                .Where(i => i.Contains("=")) // filter out empty values
                .Select(i => i.Trim().Split('=')) // trim to remove leading blank
                .Select(i => new { Name = i.First(), Value = i.Last() });

然后你可以使用它们：

foreach(var val in parts)
{
    string name = val.Name;
    string value = val.Value;
}

或者如果您喜欢Dictionary<string, string>：

string source = coockie.Substring(8); // remove the "Cookie: "
var parts = source.Split(';')
                .Where(i => i.Contains("="))
                .Select(i => i.Trim().Split('='))
                .ToDictionary(i => i.First(), i => i.Last());

然后

string host = parts["host"];

Answer 2

您应该能够遍历cookie属性。在MSDN上查看HttpWebResponse Cookie property和How To: Get and Set Cookies。无需进行任何复杂的字符串操作。

    private void ReadCookies()
    {
        HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://gmail.com");
        request.CookieContainer = new CookieContainer();

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();

        //Console.WriteLine(response.Headers.ToString());
        //Console.WriteLine(response.StatusCode.GetHashCode());

        CookieCollection IncomingCookies = response.Cookies;
        Console.WriteLine("Listing out {0} cookies received.", IncomingCookies.Count);
        foreach(Cookie cookie in IncomingCookies)
        {
            Console.WriteLine("{0} = {1}", cookie.Name, cookie.Value);
        }
        return;
    }

这个怎么样：

var sessionId = webResponse.Headers["Set-Cookie"]
    .Split(';')
    .Where(s => s.StartsWith("scandic_lb_cookie="));

在标题中拆分Cookie
