Non-existent service “request_stack”

Question

I am writing a Symfony 2.6 application and I\'ve encountered a problem when trying to inject the RequestStack into a service. What I want is to be able to get the current re

Answer 1

Use php app/console container:debug or debug:container for 2.6 to check if the service exists , and maybe you are using the wrong version of symfony

Answer 2

Since 2017 and Symfony 3.3+ this is now very simple.

1. Register services with autowiring via PSR-4 service autodiscovery

# app/config/services.yml
services:
    _defaults:
        autowire: true

    App\:
       resource: ../../src/App

2. Require RequestStack in service via Constructor Injection

<?php

namespace App;

use Symfony\Component\HttpFoundation\RequestStack;

final class SomeService
{
    /**
     * @var AnotherService 
     */
    private $requestStack;

    public function __construct(RequestStack $anotherService)
    {
        $this->requestStack = $requestStack;
    }

    public function someMethod()
    {
        $request = $this->requestStack->getCurrentRequest();
        // ...
    }
}

3. Or in Controllers, require Request as action method argument

<?php

namespace App;

use Symfony\Component\HttpFoundation\Request;

final class SomeController
{
    public function someAction(Request $request)
    {
        $request->...;
    }
}

Nothing more is needed.

Happy coding!
