How can I get Request object inside a class in Symfony 2?

Question:

I have a class in Symfony that implements an interface. I need to have $request to have POST params. This is my function:

class WebserviceUserProvider implements UserProviderInterface { public function loadUserByUsername($username) { $salt = ""; $roles = ""; // make a call to your webservice here ..... } ... }

I can't do this:

public function loadUserByUsername($username, Request $request)

because i need to implement the interface, and i get this error:

<blockquote>

FatalErrorException: Compile Error: Declaration of Actas\Gestion\UserBundle\Security\User\WebserviceUserProvider::loadUserByUsername() must be compatible with Symfony\Component\Security\Core\User\UserProviderInterface::loadUserByUsername($username)

</blockquote>

How can i get the request params? This class is called from login, and i need the password sent by it to use a WebService to authenticate the user.

Thank you very much in advance!

This is my services.xml in the Bundle:

# src/Actas/Gestion/UserBundle/Resources/config/services.yml parameters: webservice_user_provider.class: Actas\Gestion\UserBundle\Security\User\WebserviceUserProvider services: webservice_user_provider: class: "%webservice_user_provider.class%" scope: container calls: - [setServiceContainer , ["@service_container"]]

Answer1:

In addition to Czechnology's answer, you could also inject the request using a setter method. In services.yml add:

my_service: class: Acme\DemoBundle\Service\WebserviceUserProvider scope: request calls: - [setRequest , ["@request"]]

Then declare your class like this:

use Symfony\Component\HttpFoundation\Request; class WebserviceUserProvider implements UserProviderInterface { private $request; public function setRequest( Request $request ) { $this->request = $request; } // ... }

If you have scope widening issues, you could also try injecting the service container and getting the requesting from it. In services declare your service like this:

my_service: class: Acme\DemoBundle\Service\WebserviceUserProvider calls: - [setRequest , ["@service_container"]]

Now just use the container to get the request:

use Symfony\Component\DependencyInjection\ContainerInterface; use Symfony\Component\HttpFoundation\Request; class WebserviceUserProvider implements UserProviderInterface { private $request; public function setRequest( ContainerInterface $container ) { $this->request = $container->get('request'); } // ... }

Answer2:

use Symfony\Component\HttpFoundation\RequestStack; class NewService { protected $request; public function setRequest(RequestStack $request_stack) { $this->request = $request_stack->getCurrentRequest(); } }

In Config file

services: new.service: class: Acme\DemoBundle\NewService calls: - [setRequest, [@request_stack]]

Answer3:

How do you load the service? You can inject various stuff in the service:

my_service: class: Acme\DemoBundle\Service\WebserviceUserProvider arguments: [@request] scope: request

and use it in the constructor

use Symfony\Component\HttpFoundation\Request; class WebserviceUserProvider implements UserProviderInterface { private $request; public function __construct(Request $request) { $this->request = $request; } // ... }

Answer4:

I had a similar problem. May be it helps this solution. You can inject the @service_container to the service. Then you can check if the scope 'request' is active and get then the request. This is a service for creating a global variable for accesing the language variables from twig.

/** * Servicio para acceder a los datos del idioma actual de forma global. * * @author jaime * */ class IdiomaService { private $idioma; /** * Constructor de la clase. */ public function __construct(Container $container, EntityManager $manager, SecurityContext $context){ //, $request ) { if ($container->isScopeActive('request')) { $_locale = $container->get('request')->getLocale(); }else{ $_locale = 'es'; } $this->idioma = $manager->getRepository ( 'BackBundle:Idioma' )->findOneByCodigo ( $_locale); } public function getIdioma() { return $this->idioma; } }
