symfony4 - Api 平台 - 无效 IRI 而不是验证错误

问题描述

我正在为我的预订应用程序使用 API 平台。

预订与部门具有多对一的关系。

当我通过发送带有空字符串作为部门值的 POST 请求来创建新预订时，我预计会出现验证错误，但相反，我得到了“无效 IRI”

预订实体

/**
 * @ApiResource(
 *      itemOperations={
 *          "get"={
 *              "normalization_context"={
 *                  "groups"={"read-item"}
 *              }
 *          },
 *          "put"={
 *              "denormalization_context"={
 *                  "groups"={"put"}
 *              }
 *          }
 *    }
 * @ORM\Entity(repositoryClass="App\Repository\BookingRepository")
class Booking
{
    /**
     * @ORM\ManyToOne(targetEntity="App\Entity\Department", inversedBy="bookings")
     * @ORM\JoinColumn(nullable=false)
     * @Assert\NotBlank
     * @Groups({"read-item", "put"})
     */
    private $department;
}

部门实体

/**
 * @ApiResource(
 *     collectionOperations={"get"},
 *      itemOperations={"get"}
 * )
 * @ORM\Entity(repositoryClass="App\Repository\DepartmentRepository")
 */
class Department
{
    /**
     * @ORM\OneToMany(targetEntity="App\Entity\Booking", mappedBy="department")
     */
    private $bookings;
}

例如创建预订的示例请求 (POST)

{
  "department": ""
}

错误：

}

请告知我是否遗漏了什么

解决方案

不确定这是否会解决它，但您可以尝试在 @ApiResource 注释中显式添加 iri；过去为我修复了类似的错误：

 @ApiResource(
      iri="bookings",
      itemOperations={
          "get"={
              "normalization_context"={
                  "groups"={"read-item"}
              }
          },
          "put"={
              "denormalization_context"={
                  "groups"={"put"}
              }
          }
    }
 )

和

 @ApiResource(
      iri="departments",
      collectionOperations={"get"},
      itemOperations={"get"}
 )
