HTTPリクエストを使用して、次のページにログインします：https ://secure.bodytel.com/de/mybodytel.html 。その後、設定を読みたいと思います（https://secure.bodytel.com/de/mybodytel/settings.html）。これが私の問題です。2番目のリクエストを送信すると、ページにログインしなくなったと表示されます。fiddlerでデバッグすると、2つの異なるCookieIDがあることがわかりました。では、どうすればCookieを存続させることができますか？または私のリクエストでそれを送信します。

私はすでにこの投稿を読んだ：「http://stackoverflow.com/questions/11596378/getting-a-page-source-after-post-variables-have-been-sent」が、それは私をあまり助けませんでした。

これが私のコードです：using System.Text; System.Windowsを使用します。System.Windows.Controlsを使用する; System.Windows.Formsを使用します。System.Netを使用します。System.IOを使用します。System.Webを使用します。

        #region username stuff
        string benutzername = textBox_benutzername.ToString();
        string passwort = textBox_passwort.ToString();
        passwort = changeString(passwort);
        benutzername = changeString(benutzername);
        #endregion username stuff


        CookieCollection cookies = new CookieCollection();
        CookieContainer container = new CookieContainer();

リクエストごとにCookieを送信する必要があります。そうしないと、サーバーはユーザーが誰であるかを把握できません。

分かりました。Gauravにご協力いただきありがとうございます。

コードは次のとおりです。

 private void loginBtn_Click(object sender, RoutedEventArgs e)
    {

        #region username stuff
        string benutzername = textBox_benutzername.ToString();
        string passwort = textBox_passwort.ToString();
        passwort = changeString(passwort);
        benutzername = changeString(benutzername);
        #endregion username stuff

        // get the first cookie

        CookieContainer cookies = new CookieContainer();
        CookieContainer cookieContainer = new CookieContainer();
        HttpWebRequest sessionRequest = (HttpWebRequest)WebRequest.Create("http://www.bodytel.com/");
        sessionRequest.CookieContainer = new CookieContainer();
        cookies = sessionRequest.CookieContainer;
        HttpWebResponse sessionResponse = (HttpWebResponse)sessionRequest.GetResponse();
        sessionResponse.Close();

        // login 

        HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("https://secure.bodytel.com/de/mybodytel.html");
        req.CookieContainer = cookieContainer;
        req.Method = "POST";
        req.ContentType = "application/x-www-form-urlencoded";
        byte[] byteArray = Encoding.ASCII.GetBytes("login=" + benutzername + "&password=" + passwort + "&step=login");
        req.ContentLength = byteArray.Length;
        Stream newStream = req.GetRequestStream();
        newStream.Write(byteArray, 0, byteArray.Length);
        newStream.Close();
        HttpWebResponse res = (HttpWebResponse)req.GetResponse();

        // now connect to the other link

        req = (HttpWebRequest)HttpWebRequest.Create("https://secure.bodytel.com/de/mybodytel/settings.html");
        req.CookieContainer = cookieContainer;
        req.Method = "GET";
        res = (HttpWebResponse)req.GetResponse();
        StreamReader sr = new StreamReader(res.GetResponseStream());
        string source = sr.ReadToEnd();
        StreamWriter myWriter = File.CreateText(@"C:\Users\nicholas\Documents\Visual Studio 2010\Projects\BodytelConnection\BodytelConnection\bin\\Debug\test.txt");
        myWriter.Write(source);
        myWriter.Close();
        res.Close();
    }
