php - Can I give a Symfony 2 service the ability to read and write cookies? -

i have service should able read , write cookies. in symfony-like manner, service must have access request , response. can imagine it's possible pass request service through service configuration, don't know how. i'm not sure how i'm going give service ability write cookies though. suggestions on how appreciated.

note: don't want have manually pass variables service every time use it.

i think have couple of options - depends on trying store in cookie , @ point in process need read work.

i suggest first option create service, has access the request , creates response, returns ...

define service in services.yml :

services:     a_service:         class:     acme\demobundle\requestserviceclass         arguments: [@request]         scope: request 

your class :

//acme\demobundle\requestserviceclass.php class requestserviceclass {     private $request;     public function __construct(request $request){          $this->request= $request;    }      public function dosomething(){         // cookie         $value = $this->request->cookies->get('cookie');          // create cookie         $cookie = new cookie('cookie', 'value', time() + 3600 * 24 * 7);         // create response         $response = new response();         // set cookie in response         $response->headers->setcookie($cookie);         return $response;     } } 

then use service

public myaction() {     $response = $this->get('a_service')->dosomething();     return $response; } 

the other way of doing it, create kernel.response listener ... done :

add service services.yml :

services:   a_listener:     class: acme\demobundle\mylistener     tags:       - { name: kernel.event_listener, event: kernel.response, method: onkernelresponse } 

your listener class looks :

// acme\demobundle\mylistener.php  class mylistener {     public function onkernelresponse(filterresponseevent $event)     {         $response = $event->getresponse();         $request  = $event->getrequest();          // cookie         $value = $request->cookies->get('cookie');          // create cookie         $cookie = new cookie('cookie', 'value', time() + 3600 * 24 * 7);         // set cookie in response         $response->headers->setcookie($cookie);     } } 

the difference between 2 methods information available @ time of process - example service has access pass ... response listener has access in request , response - check if response expected (ie format or content) , set cookie according that.
