Amazon web services 云形成定义的lambda和api网关

我想向用于lambda的端点添加授权。 因为我不能在Lambda定义中设置它，所以我显式地创建方法

 LambdaName:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: ./lambdaDir
      FunctionName: LambdaName
      Events:
        APIEvent:
          Type: Api
          Properties:
            RestApiId: !Ref MyApi
            Path: /products
            Method: POST


  MyApi:
    Type: AWS::Serverless::Api
    Properties:
      Name: MyApi
      StageName: dev

      ProductsResource:
    Type: AWS::ApiGateway::Resource
    Properties:
      ParentId:
          Fn::GetAtt:
            - "MyApi"
            - "RootResourceId"
      PathPart: products
      RestApiId: !Ref MyApi

  ProductsCreateApiMethod:
    Type: AWS::ApiGateway::Method
    Properties:
      AuthorizationType: NONE
      AuthorizerId: !Ref Authorizer
      AuthorizationScopes:
        - someScope
      RestApiId: !Ref MyApi
      HttpMethod: POST
      ResourceId: !Ref ProductsResource

不幸的是，我得到了一个错误：

Another resource with the same parent already has this name: products (Service: AmazonApiGateway; Status Code: 409; Error Code: ConflictException; Request ID: 03ca26de-27be-11e9-82bb-536e557773f3)

看起来，当Cloud Formation试图显式创建产品资源时，它已经由lambda定义隐式创建，

我建议SAM（无服务器应用程序模型）使用swagger部署此类资源。SAM的模板类似于CloudFormation。我建议SAM（无服务器应用程序模型）使用swagger部署此类资源。SAM的模板就像一个云结构。
