FindAll() 不工作，Symfony 3 FosrestBundle API

Question

所以我用 FOSRestBundle 创建了一个 api，它通过 id

找到和 return 数据

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

结果： Result

现在我想使用方法 findAll() 来 return 存储库中的所有数据，方法如下：

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

但是它不起作用。 error image

Interventions.php 带有 JMS 序列化程序的实体

<?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;


/**

*
* @ORM\Table(name="interventions")
*@ORM\Entity(repositoryClass="CBMedBundle\Repository\InterventionsRepository")
* 
* @ExclusionPolicy("all") 
*/
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")
 * @Expose
 */
private $date;

/**
 * @var string
 *
 * @ORM\Column(name="Salle", type="string", length=20)
 * @Expose
 */
private $salle;

/**
 * @var string
 *
 * @ORM\Column(name="TypeInter", type="string", length=32)
 * @Expose
 */
private $typeInter;

/**
 * @var string
 *
 * @ORM\Column(name="TypeAnesthesie", type="string", length=50)

private $typeAnesthesie;

/**
 * @var string
 *
 * @ORM\Column(name="TrancheInter", type="string", length=50)
 * @Expose
 */
private $TrancheInter;
etc...

请问如何解决这个问题，谢谢。

Answer 1

findAll() 方法工作正常，但它不是 return 对象，而是一个对象数组，这就是你得到 404 的原因，因为你进行了以下检查。

更改您的代码：

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

给这个：

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