What is the impact of the ^ character in symfony firewall?-CodePudding

I see in the sample config for the Symfony firewall (https://symfony.com/doc/current/security.html) that routes should be specified thusly

access_control:
    - { path: ^/admin, roles: ROLE_ADMIN }
    - { path: ^/profile, roles: ROLE_USER }

But I have been doing it for quite a while without the ^ character. What does it do?

So this config seems to achieve the same thing:

access_control:
    - { path: /admin, roles: ROLE_ADMIN }
    - { path: /profile, roles: ROLE_USER }

CodePudding user response：

This is the default restriction and restricts a firewall to only be initialized if the request path matches the configured pattern.

"The pattern is a regular expression. In this example, the firewall will only be activated if the path starts (due to the ^ regex character) with /admin. If the path does not match this pattern, the firewall will not be activated and subsequent firewalls will have the opportunity to be matched for this request."

CodePudding user response：

based on the documantation:

Prepending the path with ^ means that only URLs beginning with the pattern are matched. For example, a path of /admin (without the ^) would match /admin/foo but would also match URLs like /foo/admin.
