amazon-web-services - 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:

The REST API doesn't contain any methods (Service: AmazonApiGateway; Status Code: 400; Error Code: BadRequestException; Request ID: d527f56e-a1e1-11e9-a0a4-af7563b2b15a)

该堆栈有一个 Lambda，由具有单个资源和方法的 API 触发:

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。

放置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。埋在the docs您会发现以下内容:

If you create an AWS::ApiGateway::RestApi resource and its methods (using AWS::ApiGateway::Method) in the same template as your deployment, the deployment must depend on the RestApi's methods. To create a dependency, add a DependsOn attribute to the deployment. If you don't, AWS CloudFormation creates the deployment right after it creates the RestApi resource that doesn't contain any methods, and AWS CloudFormation encounters the following error: The REST API doesn't contain any methods.
