因此,经过相当多的研究,我找到了正确的方法。需要使用入口点服务并在防火墙配置中定义它。
此方法不会弄乱防火墙配置中指定用于登录的默认页面设置。
守则
security.yml:
firewalls:
main:
entry_point: entry_point.user_login #or whatever you name your service
pattern: ^/
form_login:
# ...
src/Acme/UserBundle/config/services.yml
services:
entry_point.user_login:
class: Acme\UserBundle\Service\LoginEntryPoint
arguments: [ @router ] #I am going to use this for URL generation since I will be redirecting in my service
src/Acme/UserBundle/Service/LoginEntryPoint.php:
namespace Acme\UserBundle\Service;
use Symfony\Component\Security\Http\EntryPoint\AuthenticationEntryPointInterface,
Symfony\Component\Security\Core\Exception\AuthenticationException,
Symfony\Component\HttpFoundation\Request,
Symfony\Component\HttpFoundation\RedirectResponse;
/**
* When the user is not authenticated at all (i.e. when the security context has no token yet),
* the firewall's entry point will be called to start() the authentication process.
*/
class LoginEntryPoint implements AuthenticationEntryPointInterface
{
protected $router;
public function __construct($router)
{
$this->router = $router;
}
/*
* This method receives the current Request object and the exception by which the exception
* listener was triggered.
*
* The method should return a Response object
*/
public function start(Request $request, AuthenticationException $authException = null)
{
$session = $request->getSession();
// I am choosing to set a FlashBag message with my own custom message.
// Alternatively, you could use AuthenticationException's generic message
// by calling $authException->getMessage()
$session->getFlashBag()->add('warning', 'You must be logged in to access that page');
return new RedirectResponse($this->router->generate('login'));
}
}
登录.html.twig:
{# bootstrap ready for your convenience ;] #}
{% if app.session.flashbag.has('warning') %}
{% for flashMessage in app.session.flashbag.get('warning') %}
<div class="alert alert-warning">
<button type="button" class="close" data-dismiss="alert">×</button>
{{ flashMessage }}
</div>
{% endfor %}
{% endif %}
