I have used below code to print response from my Model file.

<?php

class CountrylistManagement implements 
   \Vendor\Module\Api\CountrylistManagementInterface
{
protected $_storeManager;
protected $objectManager;
protected $_resource;
protected $resultJsonFactory;
public function __construct(
    \Magento\Framework\App\Action\Context $context,
    \Magento\Framework\ObjectManagerInterface $objectManager,       
    \Magento\Store\Model\StoreManagerInterface $storeManager,
    \Magento\Framework\App\ResourceConnection $resource,
    \Magento\Framework\Controller\Result\JsonFactory $resultJsonFactory
) {
    $this->_objectManager = $objectManager;     
    $this->_storeManager = $storeManager;
    $this->_resource = $resource;
    $this->resultJsonFactory = $resultJsonFactory;      
    parent::__construct($context);
}
     public function postCountrylist($params)
{
    $resultArr = array();
    $request =  json_encode($params);
    $resultArr['message'] = "Success";
    $resultArr['code'] = 200;
    $resultJson = $this->resultJsonFactory->create();
    $resultJson->setData($resultArr);
    return $resultJson;
  }
}

Here I am trying to print the json response from the model file, The above code works well from controller.

Can we use $resultJson = $this->resultJsonFactory->create(); to print the response from model file?

right now its not working for me. if anyone can look into this and update where i am doing wrong please.

Please donot use \Magento\Framework\Controller\Result\JsonFactory

Use Magento\Framework\Serialize\Serializer\Json for make json response.

You have to make use serialize($resultArr) for getting json response.

Code:

<?php

namespace Devamitbera\Systemconfig\Model;

class CountrylistManagement implements \Vendor\Module\Api\CountrylistManagementInterface {

    /**
     * @var \Magento\Framework\Serialize\Serializer\Json
     */
    private $json;
    protected $_storeManager;
    protected $objectManager;
    protected $_resource;

    public function __construct(
            \Magento\Framework\ObjectManagerInterface $objectManager,
            \Magento\Store\Model\StoreManagerInterface $storeManager,
            \Magento\Framework\App\ResourceConnection $resource,
            \Magento\Framework\Serialize\Serializer\Json $json
    ) {
        $this->_objectManager = $objectManager;
        $this->_storeManager = $storeManager;
        $this->_resource = $resource;
        $this->json = $json;
    }

    public function postCountrylist($params) {
        $resultArr = array();
        $resultArr['message'] = "Success";
        $resultArr['code'] = 200;

        return $this->json->serialize($resultArr);
    }

}

  • I've used like below now, use Magento\Framework\Serialize\Serializer\Json; then return serialize($resultArr);, but still its not working Commented May 23, 2019 at 11:28
  • I think you need to remove \Magento\Framework\App\Action\Context $context, and parent::__construct($context);

  • previously i used like this, echo json_encode($resultArr,JSON_PRETTY_PRINT); this was working fine, but i need to use in magento format Commented May 23, 2019 at 11:43

I have the same issue and I just answered another similar question, I found that JsonFactory doesnt work for me in webapi or Model class, so there is another solution to return a json with the Magento\Framework\Webapi\Rest\Response class.

Try this:

$resultArr = array();
$resultArr['message'] = "Success";
$resultArr['code'] = 200;

return $this->response->setBody(json_encode($resultArr))->sendResponse();
