C＃WebClient登录网站 [英] C# WebClient Log onto Website

问题描述

我正在尝试通过提供我的（正确的）用户名和密码登录网站。

I'm trying to log onto a website by providing my (correct) username and password.

以下是代码：

        string URL = @"https://www.t-mobile.co.uk/service/your-account/login/";

        string username = "a_user";
        string password = "a_password";
        //ServicePointManager.Expect100Continue = false;

        CookieAwareClient client = new CookieAwareClient();


        NameValueCollection postData = new NameValueCollection();
        postData.Add("username", username);
        postData.Add("password", password);

        byte[] response = client.UploadValues(URL,  postData);

        ASCIIEncoding enc = new ASCIIEncoding();
        string Source = enc.GetString(response);

但是，令人惊讶的是，它没有登录。我只是回到了登录页面。

But, surprise surprise, it's not logging on. I just get the logon page back.

任何帮助将不胜感激，这现在正在解决我的问题！

Any help would be appreciated and this is doing my head in now!!

谢谢，
吉姆

为了完整起见，这是我的WebClient类-

For completeness here is my WebClient class -

public class CookieAwareClient : WebClient
{
    private CookieContainer m_container = new CookieContainer();
    protected override WebRequest GetWebRequest(Uri address)
    {
        WebRequest request = base.GetWebRequest(address);
        if (request is HttpWebRequest)
        {
            (request as HttpWebRequest).CookieContainer = m_container;
        }
        return request;
    }
}

推荐答案

此如果您尝试在浏览器中登录，则会在服务器上发布：

This is posted on server if you try to login in browser:

org.apache.struts.taglib.html.TOKEN = 81243ce1a02ff285745f7c25b86234a9& showLogin = true& upgrade = & username =用户名& password =密码& submit =登录

也尝试添加这些值，并弄清楚如何生成令牌。

Try adding those values as well, and figure out how TOKEN is generated.

编辑：检查该页面给您的cookie是否也提交了。

Check if cookies that page gives you are submited back too.

另一项编辑：太清楚了进行请求或发布数据时在服务器和浏览器（= Firefox）之间进行操作，请使用 LiveHttpHeaders 插件。

ANOTHER Too see what is going on between server and browser (=Firefox) when you are making a request or posting data use LiveHttpHeaders addon.
