amazon-web-services - 即使在显式定义之后，CloudFormation 也会部署隐式 AWS::APIGateway::Deployment

Question

尝试使用 CloudFormation/SAM 部署简单的 HelloWorld API。
我必须定义 AWS::Serverless::Api、AWS::ApiGateway::Resource、AWS::ApiGateway::Method 和AWS::ApiGateway::Deployment。但在 sam 部署期间，我看到隐式创建了另一个 AWS::ApiGateway::Deployment，它是在 API 方法之前部署的。

如何阻止创建隐式 AWS::ApiGateway::Deployment(HelloWorldAPIDeployment5332c373d4)？
它会导致以下错误:

你无法将其关闭。来自 docs :

When an AWS::Serverless::Api is specified, AWS Serverless Application Model (AWS SAM) always generates an AWS::ApiGateway::RestApi base AWS CloudFormation resource. In addition, it also always generates an AWS::ApiGateway::Stage and an AWS::ApiGateway::Deployment resource.

如果您想继续使用 AWS::Serverless::Api，您必须使用自动生成的 AWS::ApiGateway::Deployment，而不是您自己的。您可以通过将 .Deployment 附加到名称来完成此操作:

!Ref <api‑LogicalId>.Deployment

或者，根本不要使用 AWS::Serverless::Api，因为您看起来无论如何都是从头开始创建一切。
