小编Don*_*d P的帖子

我正在使用 AWS CDK，每次我去创建一个新资源（CodePipeline、VPC 等）时，我都以相同的循环结束......

• 尝试部署
• “您无权使用 foo:CreateBar”
• 更新 IAM 权限
• 尝试部署
• “您无权 baz:CreateZzz”
• 更新 IAM 权限

...再三，一而再再而三。然后与 I 相同cdk destroy，但对于 "foo:DeleteFoo"

是否有更有效的方法来确定策略执行特定 CDK 操作所需的权限？也许我可以参考文档中的某个地方？

谢谢

所以我有几个学说实体,一个订阅和一个订阅者.单个订户有许多订阅(manyToOne).我为两个实体编写了自定义规范化程序,但是一旦将规范化规范化为JSON,就很难让订阅服务器显示在订阅服务器中.

我能够让它工作的唯一方法是将"Subscriber"规范化器传递给"Subscription"规范器.看起来我应该能够使用SerializerAwareNormalizer Trait或类似的东西来让Symfony递归地规范化我的相关实体.

services:
acme.marketing.api.normalizer.subscription:
    class: acme\MarketingBundle\Normalizer\SubscriptionNormalizer
    arguments: ['@acme.marketing.api.normalizer.subscriber']
    public: false
    tags:
        - { name: serializer.normalizer }
acme.marketing.api.normalizer.subscriber:
    class: acme\MarketingBundle\Normalizer\SubscriberNormalizer
    public: false
    tags:
        - { name: serializer.normalizer }

和规范化器......

<?php
namespace acme\MarketingBundle\Normalizer;

use acme\MarketingBundle\Entity\Subscription;
use Symfony\Component\Serializer\Normalizer\NormalizerInterface;

class SubscriptionNormalizer implements NormalizerInterface
{


    private $subscriberNormalizer;

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

    public function normalize($subscription, $format = null, array $context = [])
    {

        /* @var $subscription Subscription */
        $subscriber = $subscription->getSubscriber();

        return [
            "id" => $subscription->getId(),
            "subscriber" => $this->subscriberNormalizer->normalize($subscriber, $format)
        ]; …
