我解决了这个问题.
代码如下:
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Forms;
using System.Net;
using System.IO;
using System.Web;
namespace BodytelConnection{
/// <summary>
/// Interaktionslogik für MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
webBrowser1.Navigate("http://www.bodytel.com/");
}
private void textBox_benutzername_TextChanged(object sender, TextChangedEventArgs e)
{
}
private void textBox_passwort_TextChanged(object sender, TextChangedEventArgs e)
{
}
private void loginBtn_Click(object sender, RoutedEventArgs e)
{
string benutzername = textBox_benutzername.ToString();
string passwort = textBox_passwort.ToString();
string cookieHeader;
passwort = changeString(passwort);
benutzername = changeString(benutzername);
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("https://secure.bodytel.com/de/mybodytel.html");
CookieContainer cookieContainer = new CookieContainer();
request.CookieContainer = cookieContainer;
request.Method = "POST";
string postData = "login=hans-neo@web.de&password=xxxxx&step=login";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byteArray.Length;
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string Text = "";
foreach (Cookie cook in response.Cookies)
{
Text += "COOKIE: " + cook.Name + " = " + cook.Value + "
";
}
request.AllowAutoRedirect = false;
dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
reader.Close();
dataStream.Close();
response.Close();
webBrowser1.Navigate("https://secure.bodytel.com/de/mybodytel.html");
}
private string changeString(string myString)
{
myString = myString.Replace("System.Windows.Controls.TextBox: ", "");
return myString;
}
}
