Help NPP Cookie

Alliance™ · 04/28/2014, 18:34

After few month i return back...I see which nexon change server structure and use SSL for authentication on web site.
This is my old code which i use for get NPP Cookie but now don't work i think for SSL encryption.

Code:

string cookieval = string.Empty;
                string s = "{\"account\":{\"userId\":\"" + HttpUtility.UrlEncode(username) + "\",\"password\":\"" + HttpUtility.UrlEncode(password) + "\",\"accessedGame\":\"Warrock\",\"captcha\":\"\",\"isSaveID\":false}}";

                CookieContainer webCookieContainer = new CookieContainer();
                HttpWebRequest webRequest = (HttpWebRequest)HttpWebRequest.Create(new Uri("https://passport.nexoneu.com/Service/....."));
                webRequest.CookieContainer = webCookieContainer;
                webRequest.KeepAlive = true;
                webRequest.Method = "POST";
                webRequest.ContentType = "application/json;";
                webRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36";
                webRequest.Timeout = 20000;
                webRequest.ContentLength = s.Length;
                webRequest.Proxy = null;

                using (Stream wr = webRequest.GetRequestStream())
                {
                    byte[] stringa = Encoding.ASCII.GetBytes(s);
                    wr.Write(stringa, 0, stringa.Length);
                    wr.Close();

                }
               

                HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();
                using (StreamReader read = new StreamReader(webResponse.GetResponseStream()))
                {
                    string content = read.ReadToEnd();
                    MessageBox.Show(content);

                }

When i send data i riceve this response:

There is one can help me to try to resolve this first problem?Thanks.

maybe you can sniff the new packet and change it in your source

Alliance™ · 04/28/2014, 19:24

packet data send is the same...:S

wa-sta · 04/28/2014, 19:36

Even though you are a "CLB coder!", you should just turn on Fiddler or Wireshark and check whats going on..

Alliance™ · 04/28/2014, 19:43

lol?
I open this topic because i already sniff with Fiddler and Wireshark...

~~-ToXiiC~~ · 04/28/2014, 19:43

ez u have to read before normal cookies

Alliance™ · 04/28/2014, 19:55

So what is your issue? You see whats going on so implement it.

Alliance™ · 04/28/2014, 20:12

My issue is this:

I read the normal cookie first and after send data but dont work...

~~-ToXiiC~~ · 04/28/2014, 20:13

1) WebRequest on Nexon main webpage, store cookie in the container
2) WebRequest login on

with JSON post data
3) Get your NPP

Alliance™ · 04/28/2014, 20:28

i alredy use this method but i dont know why not work

What's your problem?
Ok, the split-function is a bit "out of date" but it still working & I know this function from vba.
I can also use the "new" split function.

foreach(Cookie cookie in request.CookieContainer.GetCookies("url"))
{
if(cookie.Name == "NPP")
{
this.NPP = cookie.Value;
break;
}
}
