如何在Symfony5中使用序列化程序规范化datetime

composer require symfony/serializer

<?php

namespace App\Serializer;

use Symfony\Component\Serializer\Normalizer\NormalizerInterface;
use Symfony\Component\Serializer\Normalizer\DenormalizerInterface;

class CustomSerializer implements NormalizerInterface, DenormalizerInterface
{
    // 实现接口方法
}

use Symfony\Component\Serializer\Normalizer\DateTimeNormalizer;

class CustomSerializer implements NormalizerInterface, DenormalizerInterface
{
    private $dateTimeNormalizer;

    public function __construct(DateTimeNormalizer $dateTimeNormalizer)
    {
        $this->dateTimeNormalizer = $dateTimeNormalizer;
    }

    public function normalize($object, $format = null, array $context = [])
    {
        $normalizedData = $this->dateTimeNormalizer->normalize($object, $format, $context);

        // 对其他属性进行规范化

        return $normalizedData;
    }

    public function denormalize($data, $type, $format = null, array $context = [])
    {
        // 对其他属性进行反规范化

        return $object;
    }
}

services:
    App\Serializer\CustomSerializer:
        arguments:
            - '@serializer.normalizer.datetime'
