how make services in symfony3

Question

i have this controller

namespace InicioBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use EntidadesBundle\Entity\Usuarios;
use Symfony\Component\HttpFoundation\Session\Session;
class DefaultController extends Controller
{
    private $session;

    public function __construct(){
        $this->session = new Session();
    }

   ..... 

        public function ver_rol($rol){
        if($this->sacarRol() === $rol){ 
                 return true;
             }else{
                 return false;
             }
    }

}

and in the services.yml , i got this:

parameters:
    #parameter_name: value

services:
    app.rolSession:
        class: InicioBundle\Controller\DefaultController
        arguments: ["i dont know how get paramets"]

the problem is that it doesnt work, symfony return an error FileLoaderLoadException, that the services.yml does not caontain valid YAML

Have you considered looking at the manual? If you are using the actual Symfony framework then your posted code makes little sense. — Cerad, Sep 18 '17 at 22:10
This problem can be solved by reading the symfony documentation. Ether pass the session service to the constructor or use a setter. Both is described in the docs. — Daniel, Sep 19 '17 at 14:48

There is a space before parameters: in your services.yml file, maybe remove that and your yaml should be valid.

Also if you are passing no arguments to constructor you can just delete arguments: ["null"]

One more thing, IIRC you need to add FQCN as class name, so class: InicioBundle\Controller\Default => class: InicioBundle\Controller\DefaultController

While we are at the subject, you can type hint Request in your action and use it to getSession() or maybe inject @session service to your controller

Hi!, thaks for help, do you know how i can send arguments? – ANDRES FERNANDO MARTINEZ VALEN Sep 18 '17 at 22:07
@ANDRESFERNANDOMARTINEZVALEN in your argumenta array you can do `arguments: ['@session']` and the you have to add parameter to your conatructor, I suggest you read the documentation as someone suggested because this are pretty basic stuff and Symfony has best documentation – kunicmarko20 Sep 19 '17 at 03:42
