cookies - authentication with Java and apache HttpClient 4.5.1 -

-

my problem is, don't get, how log in java , apache httpcomponents (httpclient v4.5.1) specific site: site im trying log in. have username (test_admin) , password (testing) log in think not enough , need more. think has field security_token see when make request uri, dont know how keep or how save , afterwards. there hidden input field name login-ticket, dont know what's either. want login, because need see courses , add new ones. after trying several code implementations im stick code:

    public static void setget(closeablehttpclient httpclient) throws unsupportedoperationexception, ioexception {     httpget httpget = new httpget("http://demo.studip.de/dispatch.php/admin/courses");     closeablehttpresponse httpresponse = httpclient.execute(httpget);      system.out.println("get response status:: "             + httpresponse.getstatusline().getstatuscode());      showentity(httpresponse,httpresponse.getentity());  }   public static httpentity setparam(int count, string[] params, string[] values) {     list<namevaluepair> formparams = new arraylist<namevaluepair>();      (int = 0; < count; i++)     {         formparams.add(new basicnamevaluepair(params[i],values[i]));         system.out.println("paramater------------------> "+params[i]+"   values-------------> "+values[i]);     }        urlencodedformentity entity = new urlencodedformentity(formparams, consts.utf_8);     return entity;  }  public static void setpost(httpclient httpc) throws clientprotocolexception, ioexception {     httppost httppost = new httppost("http://demo.studip.de/dispatch.php/admin/courses");      //string[] params = {"loginname", "password"};     //string[] values = {"test_admin", "testing"};     //httpentity entity = setparam(2, params, values );      httpresponse response = httpc.execute(httppost);     system.out.println("post response status:: "             + response.getstatusline().getstatuscode());     showentity(response, response.getentity());  }   public static void showentity(httpresponse httpresp, httpentity httpclient) throws ioexception {          httpclient = httpresp.getentity();         if (httpclient != null)              httpclient = new bufferedhttpentity(httpclient);           system.out.print(entityutils.tostring(httpclient)); }      public static void main(string[] args) throws interruptedexception, ioexception {       credentialsprovider credentialsprovider = new basiccredentialsprovider();      credentialsprovider.setcredentials(authscope.any,               new usernamepasswordcredentials("test_admin", "testing"));      closeablehttpclient hc =       httpclientbuilder.create().setdefaultcredentialsprovider(credentialsprovider).build();       setget(hc);     // httpclient httpclient = httpclients.createdefault();      setpost(hc);      setget(hc);      }
