拒绝访问控制器后，如何在Yii2中设置flash消息？以下是拒绝访问的方法http://www.yiiframework.com/doc-2.0/yii-filters-accesscontrol.html：
public function behaviors()
{
return [
'access' => [
'class' => 'yii'filters'AccessControl::className(),
'only' => ['create', 'update'],
'rules' => [
// deny all POST requests
[
'allow' => false,
'verbs' => ['POST']
],
// allow authenticated users
[
'allow' => true,
'roles' => ['@'],
],
// everything else is denied
],
],
];
}
之后，它重定向到site/login。如何在那里制作类似"此部分仅适用于注册用户"的flash消息？
你能尝试添加一个拒绝回调吗？我希望这个工作：
public function behaviors()
{
return [
'access' => [
'class' => 'yii'filters'AccessControl::className(),
'only' => ['create', 'update'],
'rules' => [
// deny all POST requests
[
'allow' => false,
'verbs' => ['POST']
],
// allow authenticated users
[
'allow' => true,
'roles' => ['@'],
],
// everything else is denied
],
'denyCallback' => function ($rule, $action) {
Yii::$app->session->setFlash('error', 'This section is only for registered users.');
Yii::$app->user->loginRequired();
},
],
];
}
您还可以将denyCallback添加到每个规则中：
[
'allow' => false,
'roles' => ['@'],
'denyCallback' => function($rule, $action) {
// callback logic
}
]
