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

php, request, symfony

Solution

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');
    }
    // ...
}

Problem

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 $request) ``` because i need to implement the interface, and i get this error: FatalErrorException: Compile Error: Declaration of Actas\Gestion\UserBundle\Security\User\WebserviceUserProvider::loadUserByUsername() must be compatible with Symfony\Component\Security\Core\User\UserProviderInterface::loadUserByUsername($username) 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"]] ```
