php - How get data in Symfony2 from android's post method -

i have android app makes post function sending data symfony project. want these data , storage in bd. think problem in php code , not in android's. have tried in lot of ways no result.

my android's post function:

public string sendpost(string username, string password, string email, string city) {      httpclient httpclient = new defaulthttpclient();     httpcontext localcontext = new basichttpcontext();     httppost httppost = new httppost("https://192.168.1.120/tortillatorapi/web/new_user");     httpresponse response = null;     try      {           list<namevaluepair> params = new arraylist<namevaluepair>(4);        params.add(new basicnamevaluepair("username", username));        params.add(new basicnamevaluepair("password", password));        params.add(new basicnamevaluepair("email", email));        params.add(new basicnamevaluepair("city", city));        httppost.setentity(new urlencodedformentity(params));        response = httpclient.execute(httppost, localcontext);     }      catch (exception e)      {      }     return response.tostring(); } 

the routing new user:

new_user:     pattern: /new_user     defaults: { _controller:tortillatorapitortillatorbundle:default:newuser} 

and symfony function in controller:

public function newuseraction() {     $request = $this->getrequest();     $user = new user();     $user->setusername($request->get('username'));     $user->setpassword($request->get('password'));     $user->setemail($request->get('email'));     $user->setcity($request->get('city'));      $em = $this->getdoctrine()->getmanager();     $em->persist($user);     $em->flush();      $response = new response();     $response->setstatuscode(201);     return $response; } 

just errors saw, big comment:

change part:

and symfony function in controller:

public function newuseraction() {     $request = $this->getrequest();     $user = new user();     $user->setusername($request->get('username'));     $user->setpassword($request->get('password'));     $user->setemail($request->get('email'));     $user->setcity($request->get('city'));      $em = $this->getdoctrine()->getmanager();     $em->persist($user);     $em->flush();      $response = new response();     $response->setstatuscode(201);     return $response; } 

into this, if using annotations, otherwise have specify routing , method differently, aswell i've changed request object.:

/** *@route("yourroute", name="yourroute") *@method("post") *@template() */ public function newuseraction(request $request) {     $user = new user();     $user->setusername($request->get('username'));     $user->setpassword($request->get('password'));     $user->setemail($request->get('email'));     $user->setcity($request->get('city'));      $em = $this->getdoctrine()->getmanager();     $em->persist($user);     $em->flush();      $response = new response();     $response->setstatuscode(201);     return $response; }
