无法在Yii2中为dbManager创建自定义规则

namespace app\rbac;

use yii\rbac\Rule;

class CustomRule extends Rule
{
    public $name = 'customRule';

    public function execute($user, $item, $params)
    {
        // 在这里编写自定义规则的逻辑
        return true; // 返回true或false，表示规则是否通过
    }
}

return [
    // ...
    'components' => [
        // ...
        'authManager' => [
            'class' => 'yii\rbac\DbManager',
            'defaultRoles' => ['guest'],
            'rules' => [
                'customRule' => 'app\rbac\CustomRule',
            ],
        ],
    ],
];

use Yii;

// ...

$auth = Yii::$app->authManager;
$rule = $auth->getRule('customRule');
if ($rule === null) {
    $rule = new \app\rbac\CustomRule();
    $auth->add($rule);
}

$permission = $auth->createPermission('customPermission');
$permission->ruleName = $rule->name;
$auth->add($permission);

$role = $auth->createRole('customRole');
$auth->add($role);
$auth->addChild($role, $permission);
