symfony - 如果自定义安全包中出现身份验证错误，如何重定向到注销页面

Question

我正在尝试创建一个自定义安全包。

我可以设法让一些工作（漫长而艰难:-)）。

除了当我在某处出现身份验证错误时，我想重新路由到“注销”页面而不是登录页面。

我认为如果抛出异常，以这种方式更改 security.yml 会发送到失败路径

security:
    firewalls:
        logout:
            pattern:  ^/logout$
            security: false

        secured_area:
            pattern: ^/
            my_user_factory: true
            form_login:
                login_path: /login
                check_path: /login_check
                failure_path: /logout

由于我的基本代码一直在工作（没有真正的控制），我添加了一个异常抛出来测试身份验证错误。

class AuthProvider implements AuthenticationProviderInterface
{
//...
    public function authenticate(TokenInterface $token)
    {
        throw new BadCredentialsException('Bad credentials :)');
    }
//...

但我回到了登录页面。

这是跟踪：

// I arrive on the site
UserFactory.getPosition
UserFactory.getKey
UserFactory.getKey
UserFactory.create
CnamtsSecurityExtension.load
Configuration.getConfigTreeBuilder
AcmeSecurityExtension.load
Configuration.getConfigTreeBuilder
AuthProvider.__construct
AuthListener.__construct
AuthProvider.__construct

// Let's login
SecurityController.loginAction
AuthProvider.__construct
AuthListener.__construct
AuthListener.attemptAuthentication
UserToken.__construct
AuthProvider.supports
AuthProvider.authenticate
// The exception is thrown

UserToken.serialize
UserToken.unserialize
UserToken.serialize
AuthProvider.__construct
SecurityController.loginAction
// Back to the login page. I'd like to be on the logout one.

这是整个代码。如果删除“throw new BadCredentialsException('Bad credentials :)');” 行它应该工作。

当AuthenticationException被抛出 Symfony 调用该start身份验证提供程序的入口点类的方法（如果设置了入口点），最终将重定向响应返回到login_path. 您必须$token->setAuthenticated(false);在抛出异常之前发出问题。

要添加提供者的入口点，您UserFactory应该扩展AbstractFactory。

有关工厂和入口点的实现，请参见此处和此处。
