Question

I installed new Yii advanced framework. Nginx server.

Below url is working fine: http://yii/backend/web/index.php?r=site/index

I created new CRUD using GII and accessed: http://yii/backend/web/index.php?r=user/index

It showing below error:

An Error occurred while handling another error:

Answer 1

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()
    {
.
.
.        
    }

Answer 2

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
        ],
    ],
];
}
