如何配置无服务器S3存储桶资源以将CORS AllowOrigin设置为其功能的http端点

我正在使用Serverless来创建一个Web应用程序,该应用程序从S3存储桶提供静态内容,例如Web字体.S3存储桶配置为serverless.yml文件中的资源.其CORS配置将AllowOrigin设置为通配符.

我想将此更改为具有AllowOrigin,其中包含由Serverless创建的服务的http端点,例如31alib51b6.execute-api.eu-west-1.amazonaws.com.

我想知道是否可以在serverless.yml文件中配置它.

我的示例serverless.yml文件:

service: example-service

provider:
  name: aws
  runtime: nodejs4.3
  region: eu-west-1

functions:
  web:
    handler: handler.handler
    name: ${self:service}-${self:provider.stage}
    description: ${self:service} web application - ${self:provider.stage}
    events:
      - http:
        path: web
        method: get
      - http:
        path: web/{proxy+}
        method: get

resources:
  Resources:
    S3Assets:
      Type: AWS::S3::Bucket
      Properties: 
        BucketName: ${self:service}-${self:provider.stage}-assets
        CorsConfiguration:
          CorsRules:
            - AllowedMethods:
                - GET
                - HEAD
              AllowedOrigins:
                - "*"

您可以使用以下语句定义AllowedOrigin:

    CorsConfiguration:
      CorsRules:
        - AllowedMethods:
            - GET
            - HEAD
          AllowedOrigins:
            - Fn::Join:
              - ""
              - - "https://"
                - Ref: ApiGatewayRestApi
                - ".execute-api.eu-west-1.amazonaws.com"

"Ref:ApiGatewayRestApi"引用生成的API的内部名称.
