Is there a way to effectively convert a multidimensional JSON into an object or model?
When attempting to convert a JSON with nested structures, only the outer layer is successfully converted while inner layers remain as arrays. How can this issue be resolved?
Below are the models:
<?php
namespace AppBundle;
class Company {
/**
* @var string
*/
protected $companyName = '';
/**
* @return string
*/
public function getCompanyName()
{
return $this->companyName;
}
/**
* @param string $companyName
* @return void
*/
public function setCompanyName($companyName)
{
$this->companyName = $companyName;
}
}
class User {
/**
* @var \AppBundle\Company
*/
protected $company = null;
/**
* @var string
*/
protected $username = '';
/**
* @return \AppBundle\Company
*/
public function getCompany() {
return $this->company;
}
/**
* @param \AppBundle\Company $company
* @return void
*/
public function setCompany($company) {
$this->company = $company;
}
/**
* @return string
*/
public function getUsername() {
return $this->username;
}
/**
* @param string $username
* @return void
*/
public function setUsername($username) {
$this->username = $username;
}
}
?>
Instructions on converting JSON to model:
<?php
namespace AppBundle\Controller;
class DefaultController extends \Symfony\Bundle\FrameworkBundle\Controller\Controller
{
public function indexAction()
{
// Initialize serializer
$objectNormalizer = new \Symfony\Component\Serializer\Normalizer\ObjectNormalizer();
$jsonEncoder = new \Symfony\Component\Serializer\Encoder\JsonEncoder();
$serializer = new \Symfony\Component\Serializer\Serializer([$objectNormalizer], [$jsonEncoder]);
// Set up test model
$company = new \AppBundle\Company();
$company->setCompanyName('MyCompany');
$user = new \AppBundle\User();
$user->setCompany($company);
$user->setUsername('MyUsername');
// Serialize test model to JSON
$json = $serializer->serialize($user, 'json');
dump($user); // Model is correct, Company is an instance of \AppBundle\Company
dump($json); // JSON is valid
// Deserialize JSON to model
$user = $serializer->deserialize($json, \AppBundle\User::class, 'json');
dump($user); // Issue: Company is now an array instead of an instance of \AppBundle\Company
// Denormalize JSON to model
$userArray = $serializer->decode($json, 'json');
$user = $serializer->denormalize($userArray, \AppBundle\User::class);
dump($user); // Problem: Company is still an array instead of an instance of \AppBundle\Company
}
}
?>
