api 平台 - 无法为项目生成 IRI [英] api platform - Unable to generate an IRI for the item

问题描述

我从 API 平台开始，我正在使用示例实体Foo":

I'm starting with API Platform and I'm using the example entity "Foo":

namespace AppBundle\Entity;

use ApiPlatform\Core\Annotation\ApiResource;
use Doctrine\ORM\Mapping as ORM;


/**
 * Foo
 *
 * @ORM\Table(name="foo")
 * @ApiResource
 * @ORM\Entity
 */
class Foo
{
    /**
     * @var string
     *
     * @ORM\Column(name="bar", type="string", length=255, nullable=false)
     */
    private $bar;

    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    private $id;


}

我成功地在仪表板中看到了新实体(见图):

I succesfully see the new Entity in dashboard (See image):

当我尝试获取所有 Foo 集合时出现以下错误:

And I had the following error when I try to get all Foo collection:

curl -X GET "http://127.0.0.1:8000/foos" -H "accept: application/json"

    {
  "type": "https://tools.ietf.org/html/rfc2616#section-10",
  "title": "An error occurred",
  "detail": "Unable to generate an IRI for the item of type \"AppBundle\\Entity\\Foo\"",
  "trace": [
    {
      "namespace": "",
      "short_class": "",
      "class": "",
      "type": "",
      "function": "",
      "file": "/home/xxxx/api/vendor/api-platform/core/src/Bridge/Symfony/Routing/IriConverter.php",
      "line": 107,
      "args": []
    },

我尝试了不同的格式并检查了路线:

I tried different formats and check the the routes too:

我的服务器可能需要一些特殊的库吗?我做错了什么?

It's possible what I need some special library in my server? What I'm doing wrong?

提前致谢！

推荐答案

你的 id 缺少一个 getter

You're missing a getter for your id

public function getId()
{
    return $this->id;
}
