I am a sophomore student, because the school's education online has not out of the Windows Phone's Dean online, and itself is also interested in WP development, so try to develop
Because there is no systematic learning, only in the groping forward, the rationale behind this is very simple, not easy to achieve, the web is not suitable for the tutorial, the following is I try to write the code of the login page,
But there are some grammatical problems, I hope to help see

The spelling of this postdata may be wrong, consider the way to use key-value pairs
String loginstr = "J_username=" + TextBox1.Text + "&j_password=" + passwordbox.tostring ();
Cookiecontainer cookie = await GetCookie (loginstr, "http://60.18.131.131:11080/newacademic/common/security/login.jsp");
String content = await getcontent (cookie, "http://60.18.131.131:11080/newacademic/frameset.jsp");
Frame.navigate (typeof (BlankPage1), content);
TextBox2.Text = content;
}
Public Async task<cookiecontainer> GetCookie (string poststring,string posturl)
{
Cookiecontainer cookie = new Cookiecontainer ();
HttpWebRequest HttpRequest = (HttpWebRequest) webrequest.create (PostURL);
I don't know how to improve the information on this request header, but I'll add it anyway.
Httprequest.cookiecontainer = cookie;//Set Cookie
Httprequest.method = "POST";//post commit
httprequest.accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
Httprequest.contenttype = "application/x-www-form-urlencoded";
byte[] bytes = System.Text.Encoding.UTF8.GetBytes (poststring);
Stream stream = await httprequest.getrequeststreamasync ();
Stream. Write (bytes, 0, bytes. LENGTH);//above is the post data write, I do not know what the omission of the place
HttpWebResponse HttpResponse = (HttpWebResponse) await Httprequest.getresponseasync ();
return cookie;
}
Public async task<string> getcontent (cookiecontainer cookie,string URL)
{
string content;
HttpWebRequest HttpRequest = (HttpWebRequest) httpwebrequest.create (URL);
Httprequest.cookiecontainer = cookie;
httprequest.accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
Httprequest.contenttype = "application/x-www-form-urlencoded";
Httprequest.method = "GET";
HttpWebResponse HttpResponse = (HttpWebResponse) await Httprequest.getresponseasync ();
using (Stream Responsestream = Httpresponse.getresponsestream ())
{
using (StreamReader sr = new StreamReader (Responsestream,system.text.encoding.utf8))
{
Content = Sr. ReadToEnd ();
}
}
return content;
}
}
}
The logic is basically to first simulate landing, then get a cookie, and then take this cookie to access the landing page, (and then by parsing HTML to get the content you want, this part has not been done)
However, it is not possible to get the content returned, I hope the experienced Park friends to guide
