如何在sam模板中引用现有的lambda

Question

我正在使用 SAM 创建 ApiGateway 休息资源。我想要一个 post 方法来调用现有的 lambda 函数。我该怎么做？我尝试使用以下模板，但失败并出现错误

“失败”状态：失败。原因：模板格式错误：模板的资源块中未解析的资源依赖项 [arn:aws:lambda:us-east-1:1111111111:function:LabBytesServer-AddAccountFunction-iasdsaddsdsads]

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31

Resources:
  MyApi:
    Type: AWS::Serverless::Api
    Properties:
      StageName: dev
      DefinitionBody:
        info:
          version: '1.0'
        paths:
          /myendpoint:
            post:
              responses: { }
              x-amazon-apigateway-integration:
                uri: !Join
                  - ""
                  - - "arn:aws:apigateway:"
                    - !Ref "AWS::Region"
                    - ":lambda:path/2015-03-31/functions/"
                    - !Ref arn:aws:lambda:us-east-1:111111111:function:LabBytesServer-AddAccountFunction-das2efadsdsafasd
                    - "/invocations"

                httpMethod: POST
                type: aws_proxy
      Tags:
        app: "labBytes"
        env: "dev"

Answer 1

您可以尝试使用

!Ref

而不是使用

!Sub

并给出 lambda 函数吗？例如下面：

                uri: !Join
                  - ""
                  - - "arn:aws:apigateway:"
                    - !Ref "AWS::Region"
                    - ":lambda:path/2015-03-31/functions/"
                    - !Sub arn:aws:lambda:us-east-1:111111111:function:LabBytesServer-AddAccountFunction-das2efadsdsafasd
                    - "/invocations"
