【问题描述】：
在使用 Fn::GetAtt 函数创建 CloudFront 分配时，我们可以选择在 cloudformation 模板中获取 DomainName 的值。但是我在任何地方都找不到我们如何动态获取 Origin 的 Id 和 DefaultCacheBehaviour 的 TargetOriginId？
我可以只对我的 S3 和 ELB 使用 Ref 吗？
这是我的代码，我也使用了一些参数并更改了 Cloudfront 代码。请检查一次是否正确。
它向我抛出了一个名为“属性验证失败：[在 {/DistributionConfig/Origins/1/S3OriginConfig} 中遇到不支持的属性：[HTTPSPort、HTTPPort、OriginProtocolPolicy]]”的错误

【问题讨论】：
-
您的问题不清楚。您是在尝试引用在同一模板中创建的资源，还是在 CloudFormation 堆栈之外存在的资源？
-
我已经使用 Dev env 的 cloudformer 创建了一个模板，并希望使该模板对创建 Prod env 和未来使用有用。因此，为了使模板通用，我添加了参数，并尝试传递值以使其对任何想要拥有相同类型环境的客户有用。
-
我正在尝试引用我的模板资源。我的目的很简单，我必须创建一个模板来创建资源 VPC（以及子网、rt、igw 等）、S3、Cloudfron、ASG、ELB 和 RDS。并希望尽可能地将值作为参数传递，例如名称、CIDR 等。
-
能否编辑您的问题以包含 CloudFormation 模板的相关部分？ （仅显示构建 CloudFront Distribution 的部分和相关元素，例如 Origin。）
