REST API 的 CloudFormation 堆栈错误不包含任何方法

Question

部署 CloudFormation 堆栈时获取以下信息：

REST API 不包含任何方法（服务：AmazonApiGateway；状态代码：400；错误代码：BadRequestException；请求 ID：d527f56e-a1e1-11e9-a0a4-af7563b2b15a）

该堆栈具有由具有单个资源和方法的 API 触发的单个 Lambda：

FailureReporting:
    Type: "AWS::ApiGateway::RestApi"
    DependsOn: "MyLambdaFunction"
    Properties:
      Name: "FailureReporting"
      FailOnWarnings: true
  FailureReportingDeployment:
    Type: AWS::ApiGateway::Deployment
    Properties:
      RestApiId:
        Ref: "FailureReporting"
      Description: "Production environment supporting version-1 of the interface."
      StageName: "v1"
  Failures:
    Type: "AWS::ApiGateway::Resource"
    Properties:
      RestApiId: !Ref "FailureReporting"
      ParentId: !GetAtt ["FailureReporting", "RootResourceId"]
      PathPart: "failures"
  FailuresMethodGet:
    Type: "AWS::ApiGateway::Method"
    Properties:
      RestApiId: !Ref "FailureReporting"
      ResourceId: !Ref "Failures"
      HttpMethod: "GET"
      AuthorizationType: "NONE"
      MethodResponses:
        - StatusCode: "200"
      Integration:
        IntegrationHttpMethod: "POST"
        Type: "AWS_PROXY"
        IntegrationResponses:
          - StatusCode: "200"
        Credentials: !GetAtt [ 3FailureReportingExecuteAPI, Arn ]
        Uri: !Sub
          - "arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${lambdaArn}/invocations"
          - lambdaArn: !GetAtt [ GetFailureKeysByOrderNumber, Arn ]

我错过了我搞砸的地方。

放一个DependsOn部署资源：

  FailureReportingDeployment:
    Type: AWS::ApiGateway::Deployment
    DependsOn:
      - "FailuresMethodGet"
    Properties:
      Description: "Production environment supporting version-1 of the interface."
      RestApiId: !Ref "FailureReporting"
      StageName: "v1"

这不直观。在文档中，您会发现以下内容：

如果您在与部署相同的模板中创建 AWS::ApiGateway::RestApi 资源及其方法（使用 AWS::ApiGateway::Method），则部署必须依赖于 RestApi 的方法。要创建依赖项，请将 DependsOn 属性添加到部署。如果不这样做，AWS CloudFormation 会在创建不包含任何方法的 RestApi 资源后立即创建部署，并且 AWS CloudFormation 遇到以下错误：REST API 不包含任何方法。
