Symfony2: How to inject ALL parameters in a service?

Question

How can I inject ALL parameters in a service?

I know I can do: arguments: [%some.key%] which will pass the parameters: some.key: \"value\"

Another variant how to get parameters easy - you can just set ParameterBag to your service. You can do it in different ways - via arguments or via set methods. Let me show my example with set method.

So in services.yml you should add something like:

my_service:
    class: MyService\Class
    calls:
        - [setParameterBag, ["@=service('kernel').getContainer().getParameterBag()"]]

and in class MyService\Class just add use:

use Symfony\Component\DependencyInjection\ParameterBag\ParameterBagInterface;

and create 2 methods:

/**                                                                                                                                                                      
 * Set ParameterBag for repository                                                                                                                                       
 *                                                                                                                                                                       
 * @param ParameterBagInterface $params                                                                                                                                  
 */
public function setParameterBag(ParameterBagInterface $params)
{
    $this->parameterBag = $params;
}

/**                                                                                                                                                                      
 * Get parameter from ParameterBag                                                                                                                                       
 *                                                                                                                                                                       
 * @param string $name                                                                                                                                                   
 * @return mixed                                                                                                                                                        
 */
public function getParameter($name)
{
    return $this->parameterBag->get($name);
}

and now you can use in class:

$this->getParameter('your_parameter_name');
