AWS::Serverless::Api DefinitionBody 像这样:

  MyApi:
    Type: "AWS::Serverless::Api"
    Properties:
      StageName: 'dev'
      Domain:
        DomainName: 'mydomain.com'
        CertificateArn: 'my-arn'
        EndpointConfiguration: REGIONAL
        Route53:
          HostedZoneId: 'HOSTEDZONEID'
        BasePath:
          - /api
      DefinitionBody:
        'Fn::Transform':
          Name: 'AWS::Include'
          Parameters:
            Location: !Sub 'open-api.yml'

我曾经 Fn:Transform open-api.yml

        ...
        x-amazon-apigateway-integration:
            uri: !Sub 'arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/arn:aws:lambda:${AWS::Region}:${AWS::AccountId}:function:${FunctionName}/invocations'
            responses:
                default:
                    statusCode: "200"
            passthroughBehavior: "when_no_templates"
            httpMethod: "GET"
            type: "aws_proxy"

sam deploy --debug 我得到以下错误:

转换AWS::Include失败,原因是:指定的S3对象的内容应为有效的Yaml/JSON

出现此错误是因为在YAML代码段中使用速记符号。包含的YAML代码段的速记符号 AWS::Include 撰写本文时不支持转换。

uri: !Sub 'arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/arn:aws:lambda:${AWS::Region}:${AWS::AccountId}:function:${FunctionName}/invocations'

您必须这样做:

uri:
  Fn::Sub:
     - 'arn:aws:apigateway:${AWSRegion}:lambda:path/2015-03-31/functions/${FunctionArn}/invocations'
     - AWSRegion:
           Ref: AWS::Region
       AWSAccountId:
           Ref: AWS::AccountId
       FunctionArn:
           Fn::GetAtt: [UserServicesFunction, Arn]

看见 AWS::Include transform
