AWS SAM模板/ cloudformation没有为方法定义集成（服务：AmazonApiGateway

Question

我正在尝试部署lambda函数和API网关。我使用AWS CLI创建一个.net核心Web API项目。在AWS Web控制台上仅部署功能并手动创建API网关和资源即可。

如果我确实将API网关包括在模板中，则在通过Web控制台或CLI进行SAM包部署后，出现以下错误：

“没有为方法定义任何集成（服务：AmazonApiGateway；状态代码：400；错误代码：BadRequestException；请求ID：...。）”

这里有什么问题或遗漏吗？

SAM软件包命令：

sam package  --template-file  sam-profile.yaml --output-template-file serverless-output.yaml  --s3-bucket testapp-fewtfvdy-lambda-deployments

SAM模板：

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Resources:
  ProfileFunction:
    Type: AWS::Serverless::Function
    Properties:
      Handler: testapp.Profile.NetCoreVS::testapp.Profile.NetCoreVS.LambdaEntryPoint::FunctionHandlerAsync
      Runtime: dotnetcore2.0
      MemorySize : 128
      Timeout : 5
      CodeUri: bin/Release/netcoreapp2.0/publish
      Events:
        ProfileAny:
          Type: Api
          Properties:
            RestApiId: !Ref ProfileApiGateway
            Path: /profile/v1
            Method: GET

  ProfileApiGateway:
    DependsOn: ProfileFunction
    Type: 'AWS::Serverless::Api'
    Properties:
      StageName: Prod
      DefinitionUri: './swagger.yaml'

swagger.yaml：

---
swagger: '2.0'

  title: ProfileAPI
paths:
  "/profile/v1":
    get:
      tags:
      - Values
      operationId: ProfileV1Get
      consumes: []
      produces:
      - text/plain
      - application/json
      - text/json
      parameters: []
      responses:
        '200':
          description: Success
          schema:
            type: array
            items:
              type: string
definitions: {}

.net核心方法：

[Route("profile/v1")]
    public class ValuesController : Controller
    {
        // GET api/values
        [HttpGet]
        public IEnumerable<string> Get()
        {
            return new string[] { "value1", "value2","value_new3" };
        }


    }

您的挥霍定义丢失了x-amazon-apigateway-integration。

这应该为您提供该集成层：

---
swagger: '2.0'
info:
  version: v1
  title: ProfileAPI
paths:
  "/profile/v1":
    get:
      tags:
      - Values
      operationId: ProfileV1Get
      consumes: []
      produces:
      - text/plain
      - application/json
      - text/json
      parameters: []
      responses:
        '200':
          description: Success
          schema:
            type: array
            items:
              type: string
      x-amazon-apigateway-integration:
        httpMethod: post
        type: aws_proxy
        uri:
          Fn::Sub: arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${ProfileFunction.Arn}/invocations
definitions: {}

请注意，httpMethod x-amazon-apigateway-integration始终为POST，因为API网关始终向Lambda发出POST请求，无论您的API路由使用哪种方法。
