我在模拟登陆的时候获取不到cookie

我想模拟下人人自动登陆然后再打开新的链接，我使用一下代码获取cookie 但得到的是"";没有获取到任何的值，很是郁闷请高手指点。我断点后发现 mycookie得到空值，



    

            Test.HttpHeader header = new Test.HttpHeader();

            header.accept = "itext/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";

            header.contentType = "application/x-www-form-urlencoded";

            header.method = "POST";

            header.userAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)";

            header.maxTry = 300;



CookieCollection mycookie = Test.HTMLHelper.GetCookieCollection("http://www.renren.com/PLogin.do",

            //                   "mail=bgaidu%40163.com&password=123456789&origURL=https%3A%2F%2Fsafe.renren.com%2F&domain=renren.com&formName=&method=&isplogin=true&submit=%E7%99%BB%E5%BD%95", header);

然后我又断点 getcookiecollection 方法的代码如下，得到的也为空值。

  





 HttpWebRequest request = null;

            HttpWebResponse response = null;

            try

            {

                CookieContainer cc = new CookieContainer();

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

                request.Method = header.method;

                request.ContentType = header.contentType;

                byte[] postdatabyte = Encoding.UTF8.GetBytes(postdata);

                request.ContentLength = postdatabyte.Length;

                request.AllowAutoRedirect = false;

                request.CookieContainer = cc;

                request.KeepAlive = true;



                //提交请求

                Stream stream;

                stream = request.GetRequestStream();

                stream.Write(postdatabyte, 0, postdatabyte.Length);

                stream.Close();



                //接收响应

                response = (HttpWebResponse)request.GetResponse();

                response.Cookies = request.CookieContainer.GetCookies(request.RequestUri);



                CookieCollection cook = response.Cookies;

                //Cookie字符串格式

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



                return cook;

            }

            catch (Exception ex)

            {



                throw ex;

            }
