New controller action

It is very simple to add new actions to the REST API controller. We only need to remember three differences in the web controller:

• Verb setting for the new action

• Authenticate the setting for the new action

• Output for the new action

The first two steps are configured in the behaviors() method of the controller:

    public function behaviors()
    {
        $behaviors = parent::behaviors();
        $behaviors['verbs'] = [
                'class' => \yii\filters\VerbFilter::className(),
                'actions' => [
                    'myCustomAction'  => ['get', 'head'],
                ],
        ];
        
        $behaviors['authenticator'] = [
        'except' => 'myCustomAction',
            'class' => HttpBasicAuth::className(),
        ];
      
        return $behaviors;
    }

public function actionMyCustomAction()
{
    …
    …
    
}

In the first part of the behaviors() method, we will only set the get and head HTTP methods to call the myCustomAction...
