Question

我尝试使用C＃以编程方式登录到网页“ https://www.tagesanzeiger.ch/”

使用我的代码，我得到一个响应结果 {“状态”：“确定”，“登录证”：“ LT-8oVvgYB9PmMXGZkU7uhSy0iDwHQan”}

我在响应中有一个cookie，其中包含以下信息： Cookie名称：creid Cookie域：.tagesanzeiger.ch Cookie 1679645547384920719

不幸的是，cookie信息1-tx_user_status是匿名的，而2 tx_sub_status却没有被保留。

使用浏览器登录时，cookie设置如下：

我的代码如下所示（https://rextester.com/edit/ZPVH43356的主要来源-已修改为我的需要）：

            //https://rextester.com/edit/ZPVH43356

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

                foreach (Cookie cookie in resp.Cookies)

                    Console.WriteLine(sr.ReadToEnd());

                request = (HttpWebRequest)HttpWebRequest.Create("https://www.tagesanzeiger.ch/kinder-stecken-sich-gleich-haeufig-an-wie-erwachsene-689873876503");


                //After a successful login, you must use the same cookie container for all request
                request.CookieContainer = cookieContainer;

                using (WebResponse response = request.GetResponse())
                {
                    using (StreamReader sr2 = new StreamReader(response.GetResponseStream()))
                    {
                        Console.WriteLine(sr2.ReadToEnd());
                    }
                }

            }
            catch (Exception e)
            {
                Console.WriteLine(e);
            }

我认为通过在请求中包含cookiecontainer，它将在成功登录到下一个请求后移交。但是看来我从登录请求中收到的cookie尚未完成。

有人真的知道我是否真的登录过吗，以及如何使用已登录的信息访问页面？

登录后如何使用C＃从网页接收完整的cookie信息
