Question about services extending

Hello,

Little stupid question about the services in ci4.

How to make available a service in a whole controller or in many controllers?

For example "service('request')" i have to call it several times in each of my 'public function'.

PHP Code:

<?php namespace App\Controllers;
class User extends BaseController
{

public function test(){
  $request = service('request');
  echo $request->getIPAddress();
 }

} 


I tried to call it in the BaseController but doesn't look like it's working, if anyone can explain it to me ?

Regards, 

You don't to load it. It's always there as $this->request.
