symfony：在过滤器类上动态设置安全标记

Question

我想动态决定应用程序是否安全。 是否可以通过过滤器类来设置安全标志（通常在security.yml中设置）？

Thx为您的答案。

Answer 1

当然可以。

要管理用户证书，sfBasicSecurityUser提供了几个方法：

// Add one or more credentials 
$user->addCredential('foo'); 
$user->addCredentials('foo', 'bar'); 

// Check if the user has a credential 
echo $user->hasCredential('foo');      => true 

// Check if the user has both credentials 
echo $user->hasCredential(array('foo', 'bar'));  => true 

// Check if the user has one of the credentials 
echo $user->hasCredential(array('foo', 'bar'), false); => true 

// Remove a credential 
$user->removeCredential('foo'); 
echo $user->hasCredential('foo');      => false 

// Remove all credentials (useful in the logout process) 
$user->clearCredentials(); 
echo $user->hasCredential('bar');      => false

在你的行动，你可以访问用户对象具有的getUser（）方法：

$user = $this->getUser();
