How to fix error when integrating OkPay in yii?

Question

Yii

Given: Yii 1.0.16
Payment system OKPAY
Data comes to notification URL
In the IPN history, there are only notifications "The remote server returned an error: (401) Unauthorized"
How to fix?
$_POST array is empty

'request'=>array(
                'class' => 'HttpRequest',
                'enableCookieValidation'=>true,
                'enableCsrfValidation'=>true,
                'enableLanguage'=>true,
            ),

But in HttpRequest inherited validateCsrfToken I check the path and do Yii::app()->request->enableCsrfValidation=false;it, but it doesn't help.

Answer 1

log all inputs (post, get, server, headers) that come into the controller. In yii2, for these purposes, I overridden the method

public function beforeAction($action){
}

Maybe in your case it doesn’t even reach the controller and for some reason it is blocked at the web server level, sort it out step by step.
