CloudFormation - 如何參考無服務器使用計划？

Question

問題：

我想將現有的 API 密鑰關聯到新創建的“使用計划”，該計划是通過 AWS SAM 創建的，如下所示：

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Resources:
  ApiGatewayApi:
    Type: AWS::Serverless::Api
    Properties:
      Name: MyAPI
      OpenApiVersion: '2.0'
      EndpointConfiguration:
        Type: REGIONAL
      StageName: prod
      MethodSettings:
        - ResourcePath: "/*"
          HttpMethod: "*"
          ThrottlingBurstLimit: 1
          ThrottlingRateLimit: 1
      Domain:
        DomainName: api.mywebsite.com
        CertificateArn: 'arn:aws:acm:eu-north-1:101010101010:certificate/88888888-4444-3333-2222-1111111111'
        EndpointConfiguration: REGIONAL
        Route53:
          HostedZoneId: 'OMMITTD82737373'
        BasePath:
          - /
      Auth:
        UsagePlan:
          CreateUsagePlan: PER_API
          Description: Usage plan for this API
          Quota:
            Limit: 1000
            Period: MONTH
          Throttle:
            BurstLimit: 1
            RateLimit: 1
          Tags:
            - Key: Name
              Value: MyUsagePlan
  usagePlanKey:
    Type: 'AWS::ApiGateway::UsagePlanKey'
    Properties:
      KeyId: 2672762828
      KeyType: API_KEY
      UsagePlanId: ????????????????????

是否可以在此處引用 UsagePlanId？ 我試過： !Ref UsagePlan但沒有成功......關於如何做的任何想法？

謝謝

據我所知，無法引用作為 Api 的一部分創建的 UsagePlan。

但是，您可以在UsagePlan之外創建ApiGatewayApi作為單獨的資源，並將其與您的ApiGatewayApi相關聯。 然后您可以輕松地在UsagePlanKey中引用它：

usagePlan:
  Type: 'AWS::ApiGateway::UsagePlan'
  Properties:
    ApiStages:
      - ApiId: !Ref ApiGatewayApi
        Stage: prod
    ... (rest of the properties omitted)

usagePlanKey:
  Type: 'AWS::ApiGateway::UsagePlanKey'
  Properties:
    KeyId: 2672762828
    KeyType: API_KEY
    UsagePlanId: !Ref usagePlan
