Answer 1

Yii2 isset AccessControl
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
],
],
];
}

Answer 2

exception 'yii\web\ForbiddenHttpException' with message 'You are not
allowed to perform this action.' in
/private/var/www/yii/advanced/vendor/yiisoft/yii2/filters/AccessControl.php:151
Here is yii2 code
/**
* Denies the access of the user.
* The default implementation will redirect the user to the login page if he is a guest;
* if the user is already logged, a 403 HTTP exception will be thrown.
* #param User $user the current user
* #throws ForbiddenHttpException if the user is already logged in.
*/
protected function denyAccess($user)
{
if ($user->getIsGuest()) {
$user->loginRequired();
} else {
throw new ForbiddenHttpException(Yii::t('yii', 'You are not allowed to perform this action.'));
//this is 152 line
}
}
So I think its very clear that you need to login first, so go to http://yii/backend/web/index.php?r=user/login.
If dont have login user/login page then remove all behaviors section at the top of your UserController.
public function behaviors()
{
