I need to

Answer 1

You can also use:

$container->getParameter('api_user');

Visit http://symfony.com/doc/current/service_container/parameters.html

Answer 2

In Symfony 4.3.1 I use this:

services.yaml

HTTP_USERNAME: 'admin'
HTTP_PASSWORD: 'password123'

FrontController.php

$username = $this->container->getParameter('HTTP_USERNAME');
$password = $this->container->getParameter('HTTP_PASSWORD');

Answer 3

You can use:

public function indexAction()
{
   dump( $this->getParameter('api_user'));
}

For more information I recommend you read the doc :

http://symfony.com/doc/2.8/service_container/parameters.html

Answer 4

In Symfony 4, you can use the ParameterBagInterface:

use Symfony\Component\DependencyInjection\ParameterBag\ParameterBagInterface;

class MessageGenerator
{
    private $params;

    public function __construct(ParameterBagInterface $params)
    {
        $this->params = $params;
    }

    public function someMethod()
    {
        $parameterValue = $this->params->get('parameter_name');
        // ...
    }
}

and in app/config/services.yaml:

parameters:
    locale: 'en'
    dir: '%kernel.project_dir%'

It works for me in both controller and form classes. More details can be found in the Symfony blog.

Answer 5

In Symfony 2.6 and older versions, to get a parameter in a controller - you should get the container first, and then - the needed parameter.

$this->container->getParameter('api_user');

This documentation chapter explains it.

While $this->get() method in a controller will load a service (doc)

In Symfony 2.7 and newer versions, to get a parameter in a controller you can use the following:

$this->getParameter('api_user');

I send you an example with swiftmailer:

parameters.yml

recipients: [email1, email2, email3]

services:

your_service_name:
        class: your_namespace
        arguments: ["%recipients%"]

the class of the service:

protected $recipients;

public function __construct($recipients)
{
    $this->recipients = $recipients;
}
