Magento 2做ajax调用的正确方式？

<referenceContainer name="content">
    <block class="Vendor\Module\Block\Ajax" name="ajax.block" template="Vendor_Module::ajax.phtml" />
</referenceContainer>

<?php
namespace Vendor\Module\Controller\Index;

use Magento\Framework\Controller\ResultFactory;

class Ajax extends \Magento\Framework\App\Action\Action
{
    public function execute()
    {
        $result = $this->resultFactory->create(ResultFactory::TYPE_JSON);
        $data = ['message' => 'Hello from ajax call!'];
        $result->setData($data);
        return $result;
    }
}

require(['jquery'], function($) {
    $(document).ready(function() {
        $('.ajax-button').click(function() {
            $.ajax({
                url: '/module/index/ajax',
                type: 'POST',
                dataType: 'json',
                success: function(response) {
                    console.log(response.message);
                }
            });
        });
    });
});
