FindAll（）無法正常工作，Symfony 3 FosrestBundle API

Question

所以我用FOSRestBundle制作了一個API，該API通過ID查找並返回數據

   public function getIntAction($int){
$Interventions = $this->getDoctrine()->getRepository('CBMedBundle:Interventions')->find($int);
if(!is_object($Interventions)){
  throw $this->createNotFoundException();
}
return $Interventions;
}

結果： 結果

現在，我想使用方法findAll（），通過像這樣更改從存儲庫返回所有數據：

  public function getIntAction(){
$Interventions = $this->getDoctrine()->getRepository('CBMedBundle:Interventions')->findAll();
if(!is_object($Interventions)){
  throw $this->createNotFoundException();
}
return $Interventions;
}

但這沒用。 錯誤圖片

具有JMS序列化程序的Interventions.php實體

<?php

namespace CBMedBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use JMS\Serializer\Annotation\ExclusionPolicy;
use JMS\Serializer\Annotation\Expose;
use JMS\Serializer\Annotation\Groups;
use JMS\Serializer\Annotation\VirtualProperty;


/**

*/
class Interventions
{
/**
 * @var int
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @var \Date
 *
 * @ORM\Column(name="Date", type="date")

private $date;

/**
 * @var string

private $typeAnesthesie;

/**

private $TrancheInter;
etc...

謝謝，如何解決這個問題。

Answer 1

findAll()方法可以正常工作，但是它不返回對象，而是返回對象數組，這就是為什么要進行404檢查的原因。

更改您的代碼：

if(!is_object($Interventions)){
  throw $this->createNotFoundException();
}

對此：

if (!$Interventions) {
    throw $this->createNotFoundException();
}
