Amazon cloudformation Cloudformation API GW集成响应/响应头

这是可以使用的！参考要在响应参数内使用的S3存储桶。例如：

IntegrationResponses:
      - ResponseParameters:
          method.response.header.Access-Control-Allow-Headers: "'Content-Type,X-Amz-Date,Authorization,X-Api-Key,X-Amz-Security-Token'"
          method.response.header.Access-Control-Allow-Methods: "'POST,OPTIONS'"
          method.response.header.Access-Control-Allow-Origin: "'https://dynamicbucketname.s3-us-west-2.amazonaws.com'"
          method.response.header.Access-Control-Allow-Credentials: "'true'"

S3Bucket:
 Type: AWS::S3::Bucket
 Properties:
   PublicAccessBlockConfiguration:
     BlockPublicAcls: true
     IgnorePublicAcls: false
     BlockPublicPolicy: true
     RestrictPublicBuckets: true  
   WebsiteConfiguration:
     IndexDocument: index.html
     ErrorDocument: error.html

IntegrationResponses:
      - ResponseParameters:
          method.response.header.Access-Control-Allow-Headers: "'Content-Type,X-Amz-Date,Authorization,X-Api-Key,X-Amz-Security-Token'"
          method.response.header.Access-Control-Allow-Methods: "'POST,OPTIONS'"
          method.response.header.Access-Control-Allow-Origin: !Sub "'https://${S3Bucket.DomainName}'"
          method.response.header.Access-Control-Allow-Credentials: "'true'"

所以本质上我使用的是一个资源AWS:：S3:：Bucket，它允许模板创建Bucket。因此，名称将是动态的。我希望能够！参考原点内的S3Bucket。这可能吗？我知道它可以像

一样是静态的，一种方法是使用函数如下所示：

这是可以使用的！参考要在响应参数内使用的S3存储桶。例如：

IntegrationResponses:
      - ResponseParameters:
          method.response.header.Access-Control-Allow-Headers: "'Content-Type,X-Amz-Date,Authorization,X-Api-Key,X-Amz-Security-Token'"
          method.response.header.Access-Control-Allow-Methods: "'POST,OPTIONS'"

          method.response.header.Access-Control-Allow-Credentials: "'true'"

S3Bucket:

          method.response.header.Access-Control-Allow-Credentials: "'true'"

除了DomainName之外，还列出了其他Bucket返回值：

Hmm可能我必须转义它，但它实际上并没有给我需要的变量。它给了我访问控制允许来源“{S3Bucket}@mcgoosh抱歉。我的错误。应该是：！Sub'https://${S3Bucket}.s3-${AWS:：Region}.amazonaws.com'@mcgoosh此表单更短：！子'https://${S3Bucket.DomainName}'
