SYMFONY2:ACL,Role和ClassScope

Question

我的ACL有问题:

我使用类作用域来授予Role权限.

这是我声明ClassAce的代码:

$objectIdentity = new \Symfony\Component\Security\Acl\Domain\ObjectIdentity('class', 'Complete\\Class\\Name');
try
{
   $acl = $aclProvider->findAcl($objectIdentity);
}
catch (\Symfony\Component\Security\Acl\Exception\Exception $e)
{
   $acl = $aclProvider->createAcl($objectIdentity);
}
// retrieving the security identity of the currently role
$securityIdentity = new \Symfony\Component\Security\Acl\Domain\RoleSecurityIdentity($role);
// grant owner access
$acl->insertClassAce($securityIdentity, \Symfony\Component\Security\Acl\Permission\MaskBuilder::MASK_OWNER);
$aclProvider->updateAcl($acl);

这是我检查访问权限的代码:

$securityContext = $this->get('security.context');
$oid = new \Symfony\Component\Security\Acl\Domain\ObjectIdentity('class', 'Complete\\Class\\Name');
if (false === $securityContext->isGranted('EDIT', $oid))
{
   throw new \Symfony\Component\Security\Core\Exception\AccessDeniedException();
}

我收到一个AccessDeniedExeption,日志中显示消息:"找不到对象标识的ACL.投票拒绝访问."

我可以通过更改RoleSecurityIdentity的equals函数来解决这个问题

原来的功能是

public function equals(SecurityIdentityInterface $sid)
{
   if (!$sid instanceof RoleSecurityIdentity) {
       return false;
   }

   return $this->role === $sid->getRole();
}

但如果我改变它

public function equals(SecurityIdentityInterface $sid)
{
   if (!$sid instanceof RoleSecurityIdentity) {
       return false;
   }

   return $this->role == $sid->getRole();
}

有用...

我使用自己的角色类,这可能是个问题吗？

谢谢你的回答,

我有类似的问题.在我自己的Role类中扩展Symfony\Component\Security\Core\Role\Role解决了这个问题.

use Symfony\Component\Security\Core\Role\Role as CoreRole;

class Role extends CoreRole{ // or extends CoreRole implements RoleInterface
// my custom Role class
}

找出在相同函数中检查哪些类型的值,它必须是字符串,而不是对象.就我而言,它是角色对象.
