问题
I am working on symfony 2.3 project having the following routing code
just2_frontend_logincheck:
pattern: /login_check
It doesn't have
defaults:{ _controller: testBundle:User:login }
But it is working. But I don't know how the routing is working. Is it possible? Please advice me about the routing.
回答1:
The check_path route/path is used by your firewall to catch login requests.
This route's action is never really accessed. It's the route/url your login form posts to and the request should be processed by your firewall's provider service.
If the check_path route's action is being executed there is something wrong with the firewall (the request is not processed by your firewall).
As you can see here FOSUserBundle"s check_path is routed to SecurityController::checkAction and just throws a RuntimeException.
The configuration of the check_path can be found in app/config/security.yml under security.firewalls.<firewallname>.form_login.check_path.
It can either be a pattern like /login_check or as in your case a route name i.e. just2_frontend_logincheck but there is no underlying action.
security:
providers:
your_provider_name: your_provider_service # authentication provider
# ...
firewalls: # Required
your_firewall_name:
# ...
provider: your_provider_name
form_login:
check_path: /login_check # submit the login form here
# in your case a route name:
# just2_frontend_logincheck
Under the hood symfony calls the authenticate() method of the service your_provider_service to check the credentials provided.
You can find the class used as the provider-service using:
app/console debug:container --show-private your_provider_service
