I'm creating a small API, mostly for learning purposes, but, I might implement it into a project I'm working on. So far, I have installed the zend expressive skeleton application and set up my models and entities. I'm able to query the database and get results, but, when I return the results as a JSON Response, I can only see a list of empty arrays for each result. I would like to be able to return the actual objects that are being returned from the database instead of converting them to arrays.
HomePageHandler.php
<?php
declare(strict_types=1);
namespace App\Handler;
use App\Entity\Product;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\RequestHandlerInterface;
use Zend\Diactoros\Response\HtmlResponse;
use Zend\Diactoros\Response\JsonResponse;
use Zend\Expressive\Router;
use Zend\Expressive\Template\TemplateRendererInterface;
use App\Model\ProductModel;
class HomePageHandler implements RequestHandlerInterface
{
/** @var string */
private $containerName;
/** @var Router\RouterInterface */
private $router;
/** @var null|TemplateRendererInterface */
private $template;
private $productModel;
public function __construct(
string $containerName,
Router\RouterInterface $router,
?TemplateRendererInterface $template = null,
ProductModel $productModel
) {
$this->containerName = $containerName;
$this->router = $router;
$this->template = $template;
$this->productModel = $productModel;
}
public function handle(ServerRequestInterface $request) : ResponseInterface
{
$data = $this->productModel->fetchAllProducts();
return new JsonResponse([$data]);
//return new HtmlResponse($this->template->render('app::home-page', $data));
}
}
I'm expecting a JSON Response returned with a list of 18 "Product" entities. My results look like.
[[{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{}]]
Let me know if there is any other code you would like to see. Thanks in advance!
