In Magento2.1, I create a observer use the event catalog_product_save_after, how can I get the user who saved the product in the observer.

The way in Get customer from save event observer Magento 2 doesn't work, because it used different event.

$user = $observer->getCustomer()->getData(); doesn't work too.

Use Magento\Backend\Model\Auth\Session in the __construct, then use $this->authSession->getUser() to get the user, it will work. Other solution is welcome to post :)

namespace Vendor\Module\Observer;

use Magento\Backend\Model\Auth\Session;
use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class ProductSaveAfter implements ObserverInterface
    protected $authSession;

    public function __construct(
        Session $authSession
        $this->authSession = $authSession;

    public function execute(Observer $observer)
        $user = $this->authSession->getUser();
        $userId = $user->getId();
        $userName = $user->getUsername();
        // other codes
