Symfony 4: FOSUserBundle : Override Controller - symfony

Question

I want to separate the admin login page and user login page. I did it this way with the codes I got from some sources, but I get an error.
// config/security.yaml
security:
# https://symfony.com/doc/current/security.html#where-do-users-come-from-user-providers
encoders: ...
role_hierarchy: ...
# https://symfony.com/doc/current/security.html#where-do-users-come-from-user-providers
providers:
fos_userbundle:
id: fos_user.user_provider.username
firewalls:
dev:
...
admin:
pattern: /admin(.*)
form_login:
provider: fos_userbundle
login_path: /admin/login
check_path: /admin/login_check
default_target_path: /admin/
logout:
path: /admin/logout
target: /admin/login
anonymous: true
main:
pattern: ^/
form_login:
provider: fos_userbundle
csrf_token_generator: security.csrf.token_manager
logout: true
anonymous: true
# Easy way to control access for large sections of your site
# Note: Only the *first* access control that matches will be used
access_control:
- { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/admin/, role: ROLE_ADMIN }
- { path: ^/admin/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/admin/logout$, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/admin/login_check$, role: IS_AUTHENTICATED_ANONYMOUSLY }
The routes.yaml file is as follows.
admin_login:
path: /admin/login
defaults: { _controller: App\UserBundle\Controller\SecurityController }
and The SecurityController file is as follows.
<?php
namespace App\UserBundle\Controller;
use FOS\UserBundle\Controller\SecurityController as BaseController;
class SecurityController extends BaseController
{
public function renderLogin(array $data)
{
$requestAttributes = $this->container->get('request')->attributes;
if ('admin_login' === $requestAttributes->get('_route')) {
$template = sprintf('admin/Security/login.html.twig');
} else {
$template = sprintf('#FOSUser/Security/login.html.twig');
}
return $this->container->get('templating')->renderResponse($template, $data);
}
}
I wrote this way, but when I enter the admin / login page, I get an error like the one below.
This page isn’t working
127.0.0.1 redirected you too many times.
ERR_TOO_MANY_REDIRECTS
How can I fix this error.

Answer 1

You are having too many redirect because symfony is reading top to bottom and /admin/ is written before /admin/login or /admin/login_check so it will match with this access control.
Access control (Symfony):
For each incoming request, Symfony checks each access_control entry to
find one that matches the current request. As soon as it finds a
matching access_control entry, it stops - only the first matching
access_control is used to enforce access.
So you need to put your /admin_login before your /admin
Update your access control with something like :
access_control:
- { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/admin/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/admin/logout$, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/admin/login_check$, role: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/admin/, role: ROLE_ADMIN }
