php - Override a complicated class with multiple parameters -

i trying override class usernamepasswordformauthenticationlistener.

parameters:     security.authentication.listener.form.class: appbundle\listener\loginformlistener  class loginformlistener extends usernamepasswordformauthenticationlistener {     /**     * {@inheritdoc}     */     public function __construct(securitycontextinterface $securitycontext, authenticationmanagerinterface $authenticationmanager, sessionauthenticationstrategyinterface $sessionstrategy, httputils $httputils, $providerkey, authenticationsuccesshandlerinterface $successhandler, authenticationfailurehandlerinterface $failurehandler, array $options = array(), loggerinterface $logger = null, eventdispatcherinterface $dispatcher = null, csrfproviderinterface $csrfprovider = null)     {         parent::__construct($securitycontext, $authenticationmanager, $sessionstrategy, $httputils, $providerkey, $successhandler, $failurehandler, $options, $logger, $dispatcher, $csrfprovider);     }      protected function attemptauthentication(request $request)     {          if (null !== $this->csrftokenmanager) {             $csrftoken = $request->get($this->options['csrf_parameter'], null, true);              if (false === $this->csrftokenmanager->istokenvalid(new csrftoken($this->options['intention'], $csrftoken))) {                 throw new invalidcsrftokenexception('invalid csrf token.');             }         }          if ($this->options['post_only']) {             $username = trim($request->request->get($this->options['username_parameter'], null, true));             $password = $request->request->get($this->options['password_parameter'], null, true);         } else {             $username = trim($request->get($this->options['username_parameter'], null, true));             $password = $request->get($this->options['password_parameter'], null, true);         }          $request->getsession()->set(security::last_username, $username);          $apirequest = new apirequest();         $apirequest->addmethod('login', array('email' => $username, 'password' => $password));         $response = $apirequest->sendrequest();         dump($response);         exit;     } } 

but when execute it, have error :

catchable fatal error: argument 1 passed appbundle\listener\loginformlistener::__construct() must implement interface symfony\component\security\core\securitycontextinterface, instance of symfony\component\security\core\authentication\token\storage\tokenstorage given, called in /users/dimitri/sites/rennes/app/cache/dev/appdevdebugprojectcontainer.php on line 4039 , defined 

any idea how can make work ?

you can change securitycontextinterface type hint tokenstorageinterface in class , should work fine - class service has been changed (deprecated in 2.7) , example code might outdated.

check blog post entry more info securitycontextinterface vs tokenstorageinterface
