Today, we will see how to return json data from controller while doing an ajax call.
Situation may come that you are doing some customization and need to deal will json data from controller then here is the way how we can go for it.
For that we can use the magento core class,
Magento\Framework\Controller\ResultFactory
which has list of constant mapped to corresponding classes :
self::TYPE_JSON => 'Magento\Framework\Controller\Result\Json', self::TYPE_RAW => 'Magento\Framework\Controller\Result\Raw', self::TYPE_REDIRECT => 'Magento\Framework\Controller\Result\Redirect', self::TYPE_FORWARD => 'Magento\Framework\Controller\Result\Forward', self::TYPE_LAYOUT => 'Magento\Framework\View\Result\Layout', self::TYPE_PAGE => 'Magento\Framework\View\Result\Page'
among these, we can use the constant to return json data :
const TYPE_JSON = 'json';
Now here is the complete code to implement above.
<?php

*/
namespace Webkul\<modulename>\Controller\Attachment;
use Magento\Framework\Controller\ResultFactory;
class <action> extends \Magento\Framework\App\Action\Action
{
/**
* @var \Magento\Framework\App\Action\Contex
*/
private $context;
/**
* @param \Magento\Framework\App\Action\Context $context
*/
public function __construct(
\Magento\Framework\App\Action\Context $context
) {
parent::__construct($context);
$this->context = $context;
}
/**
* @return json
*/
public function execute()
{
$whoteData = $this->context->getRequest()->getParams();
$resultJson->setData(["message" => ("Invalid Data"), "suceess" => true]);
return $resultJson;
}
}
This is all we need , hope this help you out. happy coding.
