关于C# httpwebrequest Cookie 的问题

左边是访问页面监测到的 有cookie 右边是我用httpwebrequest访问的 没有cookie

下面是代码 求赐教
string url = "http://webgame.ali213.net/webgame_action/code.php"; //验¨¦证¡è码?页°3面?

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

request.Accept = "*/*";

request.Method = "GET";

request.Referer

= "http://web.ali213.net/fahao/1260994.html";

request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; GTB7.5; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; doyo 2.6.1)";

request.Headers.Add("Accept-Encoding", "gzip, deflate");

request.Headers.Add("Accept-Language", "zh-CN");

request.CookieContainer = cookies;

request.CookieContainer = new CookieContainer(); //暂Y存ä?到Ì?新?实º¦Ì例¤y

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

response.Close();

cookies = request.CookieContainer; //保À¡ê存ä?cookies

string strCookies = request.CookieContainer.GetCookieHeader(request.RequestUri);

在线等,好像没分了

获取完整cookie代码

[DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
        static extern bool InternetGetCookieEx(string pchURL, string pchCookieName, StringBuilder pchCookieData, ref 
                    System.UInt32 pcchCookieData, int dwFlags, IntPtr lpReserved);
        [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
        static extern int InternetSetCookieEx(string lpszURL, string lpszCookieName, string lpszCookieData, int dwFlags, IntPtr
                                dwReserved);
                                 /// <summary>
        /// 获取完整cookie
        /// </summary>
        /// <param name="url"></param>
        /// <returns></returns>
        private static string GetCookies(string url)
        {
            uint datasize = 256;
            StringBuilder cookieData = new StringBuilder((int)datasize);
            if (!InternetGetCookieEx(url, null, cookieData, ref datasize, 0x2000, IntPtr.Zero))
            {
                if (datasize < 0)
                    return null;


                cookieData = new StringBuilder((int)datasize);
                if (!InternetGetCookieEx(url, null, cookieData, ref datasize, 0x00002000, IntPtr.Zero))
                    return null;
            }
            return cookieData.ToString();
        }

追问

试过了,原页面有三条Cookie 用这个方法能拿到第一条cookie  后面还好几个拿不到

追答

对啊
例如模拟登录时候，你登录以后就要拿到cookie、然后存起来，request的时候，在赋值给request.CookieContainer
