Question

我正在尝试使用如下Cloudformation模板创建API网关：

Resources:
 InvoiceApi:
  Type: AWS::ApiGateway::RestApi
  Properties:
    Description: an Api for our Invoicegen App
    Name: !Ref ApiName
    ApiKeySourceType: !Ref ApiKeySourceType
    BinaryMediaTypes:
    - !Ref binaryMediaType1
    - !Ref binaryMediaType2
    BodyS3Location:
     Bucket:
       Fn::ImportValue: !Sub ${EnvironmentName}-SwaggerApiBucket-Name
     Key: swaggertest.yaml
     ETag: !Ref ETag
     EndpointConfiguration:
     Types:
      - REGIONAL
     FailOnWarnings: true
     MinimumCompressionSize: !Ref minimumCompressionSize

S3存储桶上的Swagger-yaml文件如下所示：

  swagger: '2.0'
  info:
    version: '2016-08-17T18:08:34Z'
    title: InvoicegenAPI
  basePath: "/LATEST"
  schemes:
   - https
  paths:
    /greeting:
       get:
         summary: Get Greeting
         parameters:
          - name: name
            in: query
            required: false
            type: string
        produces:
          - application/json
        responses:
          '200':
            description: 200 response
        x-amazon-apigateway-integration:
          requestTemplates:
            application/json: '{"name": "$input.params(''name'')"}'
          uri:
            Fn::Join:
             - ''
             - - 'arn:aws:apigateway:'
               - Ref: AWS::Region
               - ":lambda:path/2015-03-31/functions/"
               - Fn::GetAtt:
                 - InvoiceLambda
                 - Arn
               - "/invocations"
         responses:
           default:
             statusCode: '200'
         httpMethod: POST
         type: aws

不幸的是，它引发了这样的错误：

Unable to parse API definition because of a malformed integration at path /greeting. (Service: AmazonApiGateway; Status Code: 400; Error Code: BadRequestException; Request ID: 2cf08a97-e66f-11e8-afee-fb6b03568b64)

我仔细检查了Swagger文件，所有缩进看起来都很好。我想念什么？

已经有一个线程处理此问题，但尚未产生任何解决方案。

Passing ARN reference from CloudFormation to Swagger

提前

我认为您的问题是对引用的S3文件使用BodyS3Location属性，该属性可能不解析YAML文件，因此无法解析您的复杂功能。

我的建议是您更改为“正文+ AWS::Include转换”，类似于在Passing ARN reference from CloudFormation to Swagger上建议的内容。尝试将此作为您的资源：

Resources:
 InvoiceApi:
  Type: AWS::ApiGateway::RestApi
  Properties:
    Description: an Api for our Invoicegen App
    Name: !Ref ApiName
    ApiKeySourceType: !Ref ApiKeySourceType
    BinaryMediaTypes:
    - !Ref binaryMediaType1
    - !Ref binaryMediaType2
    Body:
      Fn::Transform:
        Name: AWS::Include
        Parameters:
          Location: !Sub 's3://${EnvironmentName}-SwaggerApiBucket-Name/swaggertest.yaml'
    EndpointConfiguration:
    Types:
    - REGIONAL
    FailOnWarnings: true
    MinimumCompressionSize: !Ref minimumCompressionSize

带有存储在S3存储桶中的AWS扩展的Swagger文件，用于使用Cloudformation创建API
