将 null 传递给字符串字段时，API 平台返回类型错误而不是验证错误 [英] API Platform returns type error instead of validation error when passing null to a string field

问题描述

我正在使用

验证结构示例

解决方案

感谢 Symfony Slack 频道 #api-platform 中的人解决了这个问题.

在序列化过程中使用了 Doctrine 列定义，以便解决问题，需要 nullable=true.添加后，序列化过程开始工作，并在验证级别捕获空值，返回预期的响应结构.

I'm using API Platform v2.2.5, and in the process of writing tests for my resources I've discovered that, when null is provided for a field of type string, an error response is being returned during the denormalization process, which includes a non client-friendly message and a stack trace. This is different to if an empty string is provided or the field is omitted completely, which returns a structured validation response. How can I instead return a validation error response as when an empty string is provided?

Entity

class MyEntity 
{
    /**
     * @var string|null
     *
     * @ORM\Column(type="string", length=255)
     *
     * @Assert\NotBlank
     *
     * @Groups({"read", "write"})
     */
    private $title;

    /**
     * @return null|string
     */
    public function getTitle(): ?string
    {
        return $this->title;
    }

    /**
     * @param string $title
     * @return WorkoutTemplate
     */
    public function setTitle(?string $title): self
    {
        $this->title = $title;

        return $this;
    }
}

Resource configuration

App\Entity\MyEntity:
  collectionOperations
    post:
      denormalization_context:
        groups:
          - write

Error response

Example of validation structure

解决方案

Figured it out thanks to the guys in the Symfony Slack channel #api-platform.

The Doctrine column definitions are used during the serialization process so to fix the issue, nullable=true was required. Once that was added, the serialization process worked and the null value was caught at the validation level, returning the expected response structure.
