amazon-web-services - 从 Swagger 读取 AWS Region 和 AccountId

Question

如何从 swagger 文件的 x-amazon-apigateway-integration 获取 AWS::Region 和 AWS::AccountId？

我在 the docs 之后尝试了多种组合，但没有运气 - 在构建 Cloudformation 堆栈时总是收到“Invalid ARN”。

我期望能够在 swagger 文件中执行类似的操作:

x-amazon-apigateway-integration:
  uri:
    Fn::Sub arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/arn:aws:lambda:${AWS::Region}:${AWS::AccountId}:function:${stageVariables.myFunctionName}/invocations

但是，如果我对区域和帐户 ID 进行硬编码，它就会起作用:

x-amazon-apigateway-integration:
  uri: arn:aws:apigateway:us-east-1:lambda:path/2015-03-31/functions/arn:aws:lambda:us-east-1:123456789:function:${stageVariables.myFunctionName}/invocations

Answer 1

我有类似的东西可以工作。

  ApiGateway:
    Type: 'AWS::ApiGateway::RestApi'
    Properties:
      Body:
        openapi: 3.0.1
        paths:
          '/myGetEndpoint':
            get:
              x-amazon-apigateway-integration:
                uri: !Sub 'arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/arn:aws:lambda:${AWS::Region}:${AWS::AccountId}:function:myLambdaFunction/invocations'
