我尝试通过 Httprequest 登录网站并回复一些信息。我保存了 Cookie 响应。那么我怎么知道我登录成功了，我尝试通过 Cookie 加载带有新表单的网站，但它没有登录。所以你能帮我吗......这是我的代码：

登录代码：

HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create(new Uri("https://www.nike.com/profile/login?Content-Locale=en_US"));
            getRequest.CookieContainer = new CookieContainer();
            getRequest.CookieContainer.Add(myLoginCookies);
            getRequest.Method = WebRequestMethods.Http.Post;
            getRequest.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
            getRequest.UserAgent = userAgent;
            getRequest.Referer = "http://www.nike.com/";
            getRequest.Accept = "application/json, text/javascript, */*; q=0.01";
            getRequest.KeepAlive = true;

            string postData = "login=" + username + "&rememberMe=false&password=" + password;

            try
            {
                using (StreamWriter writer = new StreamWriter(getRequest.GetRequestStream()))
                    writer.Write(postData.ToString());
               HttpWebResponse getResponse = (HttpWebResponse)getRequest.GetResponse();

               using (StreamReader reader = new StreamReader(getResponse.GetResponseStream()))
                    returnData = reader.ReadToEnd();
                //MessageBox.Show(returnData);
               myLoginCookies.Add(getResponse.Cookies);
                if (myLoginCookies.Count > 1)
                {
                    return new NikeStore(myLoginCookies, returnData);                
                }
                else
                {
                    MessageBox.Show("login failed");
                    return null;
                }
            }
            catch (WebException ex)
            {
                MessageBox.Show(ex.Message);
                return null;
            }

而这个通过 Cookie 加载网站的代码返回

public Form_OpenCart(CookieCollection oCookie, string url_page)
        {
            InitializeComponent();

            foreach (Cookie cook in oCookie)
            {
                cookie.Add(cook);
            }
            url = url_page;
        }

        private void Form_OpenCart_Load(object sender, EventArgs e)
        {
            url = "http://store.nike.com/us/en_us/";
            if (cookie != null)
            {
                foreach (Cookie cook in cookie)
                {
                    cookie_string += cook.ToString() + ";";
                    InternetSetCookie(url, cook.Name, cook.Value);
                }

                webBrowser1.Navigate(url);               
            }
            else
            {
                MessageBox.Show("huhuhu");
            }

请帮助我。我尝试了很多，但我无法成功。

在将 HttpWebRequest 用于 HTTPS url 时，我曾多次遇到过类似的问题。所以我切换到 Curl Lib c# 。它每次都有效。

让我知道您需要示例代码。使用 HttpWebRequest 很可能会丢失 cookie，其中一些是进行会话所需的，因此请尝试使用 CurlLib 并使用它们。

使用这个：https ://www.dropbox.com/s/0l2rkczij11m0t4/InfoSharing.rar?dl=0

将所有 Dll 添加到您的 Debug 文件夹中，然后在项目中引用这个LibCurlNet.dll 并使用我发送的类。只需使用它来获取 html 。如果你想使用 post as emptyHttpWebRequest (Get).

                    HTTP http = new HTTP();
                    http.setCookie("Cookies\\" + UserName + ".txt");
                    string Url = "";
                    string Post = "";
                    string r = "";

                    //Get info
                    Url = "https://www.example.com/reg/join?trk=hb_join";

                    r = http.Post(Url, Post, "","");
