Jsoup를 이용하여 web site login 하기..?!?

Question

 

웹 페이지에 로그인해서 데이터를 좀 가져오려고 합니다.

 

JSOUP 라이브러리를 사용하구 있구요.

web page의 소스는 아래와 같은데 아무리 시도해봐도 로그인을 정상적으로 하지 못하는것 같네요..ㅠㅠ

혹시 조언 좀 해주실분 계신가요..1?

제 android source는 아래와 같습니다......ㅠㅠ

  Connection.Response res = Jsoup.connect("http://www.ddanzi.com/index.php?mid=free&act=dispMemberLoginForm")
                .followRedirects(true)
                .data("user_id", "myid")
                .data("password", "mypassword")
                .method(Connection.Method.POST)
                .execute();

        Document document = Jsoup.connect("http://www.ddanzi.com/index.php?act=dispMemberInfo")
                .followRedirects(true)
                .cookies(res.cookies())
                .method(Connection.Method.POST)
                .post();
