Melde dich auf die Seite mit HttpWebRequest

Question

Wie kann ich auf die Seite http://www.bhmobile.ba/portal/index von HttpWebRequest verwenden?

Login-Taste ist "Pošalji" (linke obere Ecke).

HTML-Quelle der Login-Seite:

<table id="maintable" border="0" cellspacing="0" cellpadding="0" style="height:100%; width:100%">
  <tr>
    <td width="367" style="vertical-align:top;padding:3px"><script type="text/javascript">
function checkUserid(){
    if (document && document.getElementById){
        var f = document.getElementById('userid');
        if (f){
            if (f.value.length < 8){
                alert('Korisničko ime treba biti u formatu 061/062 xxxxxx !');
                return false;
            }
        }
    }
    return true;
}
</script>
<div style="margin-bottom:12px"><table class="leftbox" style="height:184px; background-image:url(/web/2007/slike/okvir.jpg);" cellspacing="0" cellpadding="0">
    <tr>
        <th style="vertical-align:middle"><form action="http://sso.bhmobile.ba/sso/login" method="post" onSubmit="return checkUserid();">

            <input type="hidden" name="realm" value="sso">

                </tr>
            </table>
            <div style="padding:12px;">
                <a href="/portal/show?idc=1121">Da li ste novi BH Mobile korisnik?</a><br />

            </div>
        </form></th>
    </tr>

</table></div>

Answer 1

Machen Sie

ein neues default.aspx, und setzen diese in der Code-behind. Ich kann nicht testen, weiter auf der Grundlage Ihrer aktuellen Frage, weil Sie keinen gültigen Benutzernamen / Passwort enthalten waren

    using System; 
    using System.Web;
    using System.Net; 
    using System.IO;
    using System.Web.UI;
    using System.Web.UI.WebControls; 

namespace Foo
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {


            HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://sso.bhmobile.ba/sso/login"); 
            req.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705;)"; 
            req.Method = "POST";
            req.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
            req.Headers.Add("Accept-Language: en-us,en;q=0.5");
            req.Headers.Add("Accept-Encoding: gzip,deflate");
            req.Headers.Add("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
            req.KeepAlive = true;
            req.Headers.Add("Keep-Alive: 300");
            req.Referer ="http://sso.bhmobile.ba/sso/login";

            req.ContentType = "application/x-www-form-urlencoded"; 

            String Username = "username";
            String PassWord = "Password";

            StreamWriter sw = new StreamWriter(req.GetRequestStream());
            sw.Write("application=portal&url=http%3A%2F%2Fwww.bhmobile.ba%2Fportal%2Fredirect%3Bjsessionid%3D1C568AAA1FB8B5C757CF5F68BE6ECE65%3Ftype%3Dssologin%26url%3D%2Fportal%2Fshow%3Bjsessionid%3D1C568AAA1FB8B5C757CF5F68BE6ECE65%3Fidc%3D1023278&realm=sso&userid=" + Username + "&password=" + password + "&x=16&y=11");
            sw.Close();

            HttpWebResponse response = (HttpWebResponse)req.GetResponse();


            StreamReader reader = new StreamReader(response.GetResponseStream());
            string tmp = reader.ReadToEnd();

            foreach (Cookie cook in response.Cookies)
            {
                tmp += "\n" + cook.Name + ": " + cook.Value;
            }


            Response.Write(tmp);
            Response.End();

        }
    }
}

Answer 2

Sie können den Bau in der WebClient-Objekt verwenden, anstatt den Antrag selbst erstellen.

WebClient wc = new WebClient();
wc.Credentials = new NetworkCredential("username", "password");
string url = "http://foo.com";          
try
{
    using (Stream stream = wc.OpenRead(new Uri(url)))
    {
        using (StreamReader reader = new StreamReader(stream))
        {
            return reader.ReadToEnd();
             }
    }
}
catch (WebException e)
{
    //Error handeling
}
