OpenDaylight Rest API with Java -


Before posting this question, I'm sure how to ask.

I am trying to connect to the Open Daylight Controller with Java, I am trying to connect by consuming the rest of the services provided by the controller. My problem is, when I send an HTTP request, I can not get more than the entry, I'm not sure that this is possible. Instead of getting topology or other answers from the controller, I'm getting the HTML of the entry form.

Besides, I'm not sure that I should be connected in this way.

Any help / guidance is highly appreciated :)

My code is for making connections: 

  public string getContent (string url) IOException throws {String cont = ""; CloseableHttpClient httpclient = HttpClients.createDefault (); Http post http post = new HTTP post (url); List & lt; NameValuePair & gt; Nvps = new arreelist & lt; NamevaluePair & gt; (); Nvps.add (new binarynamewallpayer ("j_username", "username")); nvps.add (new binarynamewallpayer ("j_password", "password")); httpPost.setEntity (new UrlEncodedFormEntity (nvps)); CloseableHttpResponse response2 = httpclient.execute (httpPost); try {system.out.println (response2.getStatusLine ()); HttpEntity entity2 = response2.getEntity (); BufferedReader Reader = New BufferedReader (New InputStreamReader (entity2.getContent ())); String line = ""; While ((line = reader. Readline ()) = null) {cont + = line + "\ n"; }} Finally {response2.close (); } For return; }   
 When I run the code, this is what is printed:  
 HTTP / 1.1 200 OK

DOCTYPE html & gt; & Lt; Html & gt; & Lt; Top & gt; & Lt; Meta charset = "UTF-8" & gt; & Lt; Title & gt; Open Daylight - Login & lt; / Title & gt; & Lt; script src = "/ js / bootstrap.min.js" & gt; & Lt; / Script & gt; & Lt; Script type = "text / javascript" & gt; Less = {env: "production"}; & Lt; / Script & gt; & Lt; script src = "/ js / less-1.3.3.min.js" & gt; & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Form action = "j_security_check; jsessionid = LONGID" id = "form" method = "post" & gt; & Lt; Div class = "container" & gt; & Lt; Div class = "content" & gt; & Lt; Div class = "login-form" & gt; & Lt; Div id = "logo" & gt; & Lt; / Div & gt; & Lt; Fieldset & gt; & Lt; Div class = "control-group" & gt; & Lt; Input type = "text" name = "j_username" placeholder = "user name" & gt; & Lt; / Div & gt; & Lt; Div class = "control-group" & gt; & Lt; Input type = "password" name = "j_password" placeholder = "password" & gt; & Lt; / Div & gt; & Lt; Button class = "btn btn-primary" type = "submit" value = "sign in" & gt; & Lt; div class = "icon-login" & gt; & Lt; / Div & gt; Sign in & lt; / Button & gt; & Lt; / Fieldset & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Form & gt; & Lt; / Body & gt; & Lt; / Html & gt; The problem authentication seems to be encoded with username and password in Base64.
