php - How to inject @request_stack or @request in listener -

i have listener:

use symfony\component\httpkernel\httpkernelinterface; use symfony\component\httpkernel\event\filtercontrollerevent; use symfony\component\httpkernel\event\filterresponseevent; use symfony\component\httpfoundation\request;  class controllerlistener {     public function onkernelcontroller( filtercontrollerevent $event, request $request )     {         if (httpkernelinterface::master_request === $event->getrequesttype()) {             $controllers = $event->getcontroller();             if (is_array( $controllers )) {                 $controller = $controllers[0];                 if (is_object( $controller )) {                     if (method_exists( $controller, 'parcontrol' )) {                         $controller->parcontrol(                             $controller->getrequest(),                             $controller->getrequest()->get( 'action' ),                             $controller->getrequest()->get( 'context' ),                             $controller->getrequest()->get( 'page' ),                             $controller->getrequest()->get( 'case' ),                             $controller->getrequest()->get( 'subset' )                         );                     }                      if (method_exists( $controller, 'adminprojectcontrol' )) {                         // method need pass request $request                           $controller->adminprojectcontrol($request);                     }                      if (method_exists( $controller, 'accesscontrol' )) {                         $controller->accesscontrol();                     }                 }             }         }     }      public function onkernelresponse( filterresponseevent $event )     {         utilities::flashdebugloginmessage();     } } 

and it's defined service @ services.yml:

pdone.listener.preexecute:     class: groupdca\pdonebundle\listener\controllerlistener     arguments: [@request]     public: true     scope: request     tags:         - { name: kernel.event_listener, event: kernel.controller, method: onkernelcontroller }         - { name: kernel.event_listener, event: kernel.response, method: onkernelresponse } 

but should doing wrong since got 3 errors:

contexterrorexception in controllerlistener.php line 12: catchable fatal error: argument 2 passed groupdca\pdonebundle\listener\controllerlistener::onkernelcontroller() must instance of symfony\component\httpfoundation\request, string given

contexterrorexception in controllerlistener.php line 12: catchable fatal error: argument 2 passed groupdca\pdonebundle\listener\controllerlistener::onkernelcontroller() must instance of symfony\component\httpfoundation\request, string given

logicexception in bootstrap.php.cache line 3118: no listeners of "kernel.exception" event set response

so, how inject request listener? can that? have read this post here not how this.

filtercontrollerevent gives access request:

public function onkernelcontroller(filtercontrollerevent $event) {     $request = $event->getrequest();             // ... } 

if need request in listeners event not provide request, use the request stack:

use symfony\component\httpfoundation\requeststack;  class myservice {     private $requeststack;      public function __construct(requeststack $requeststack)     {         $this->requeststack = $requeststack;     }      public function dosomething()     {         $request = $this->requeststack->getcurrentrequest();          // ...     } } 

injecting request deprecated , removed. request stack way go. don't use request scope either.
