How to get bodyParams data from MultipartFormData?

Question

Yii

I send the form to the server with a PUT request, there is data in the console.
on the back of the parser settings

'parsers' => [
                'multipart/form-data' => 'yii\web\MultipartFormDataParser'
            ]

But Yii::$app->request->getBodyParams(); empty.
If I send json and use yii\web\JsonParser then the data comes normally.
