How to close the site admin?

Question

symfony

Good day!
Faced with the need to close access to the site admin panel on symphony. It is entered from the page using a login-password, but you need to isolate it from unwanted people in principle.
At first I thought to use the standard htaccess tools, but the problem is that the login page looks like site.ru/login , and the admin panel site.ru/admin
Physically, these directories do not exist, so there is no way to put the htaccess file there.
Is there any way to solve this problem?

Answer 1

In order not to spread logic in different places and not be dependent on apache, I would use standard tools:
symfony.com/doc/2.0/book/security.html#basic-examp...

security:
    encoders:
        Symfony\Component\Security\Core\User\User: plaintext

    providers:
        admin:
            memory:
                users:
                    %admin_username%: # парметры admin_username и admin_password можно задавать в parameters.yml
                        password: %admin_password%
                        roles: 'ROLE_SYNC'

    firewalls:
        admin_area:
            provider: admin
            pattern:    ^/admin
            logout:
                path:   /admin/logout
                target: /admin
            http_basic: ~
            anonymous: false

    access_control:
        - { path: ^/admin/login, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/admin/administrator, role: IS_AUTHENTICATED_FULLY }
        - { path: ^/admin, role: IS_AUTHENTICATED_REMEMBERED }

Denying access only to the private.zip file

<Files /admin/index.php> 
AuthType Basic 
AuthName "Private zone. Only for administrator!" 
AuthUserFile  /usr/host/mysite/.htpasswd 
require valid-user 
</Files>

php.net/manual/ru/features.http-auth.php
Take the second example as a sample and change it for yourself. Place the code at the beginning of index.php, as I understand it, everything goes through it. And set a condition so that this code works only when accessing the admin panel.
