将TTL设置为API网关

Question

我正在使用云形式，并启用了这样的缓存：

  Type: AWS::ApiGateway::Stage
  Properties:  
     CacheClusterEnabled: true
     CacheClusterSize: 0.5

我的方法取自Swagger。这是我的招摇文件

/v1/myPath/{id}:
get:
  tags:
    - Books
  operationId: getBook
  parameters:
    - name: id
      in: path
      description: The ID of the book to retrieve
      type: integer
      format: int32
      required: true
    - name: custom-header
      in: header
      type: string
  responses:
    '200':
  x-amazon-apigateway-integration:
    type: aws_proxy
    httpMethod: POST
    uri: arn:aws:apigateway:us-west-1:lambda:path...
    passthroughBehavior: when_no_match
    requestParameters:
      integration.request.header.custom-header: method.request.header.custom-header
    cacheKeyParameters:
      - method.request.header.custom-header

如何在Swagger.yaml中为我的Get请求设置缓存TTL？我似乎找不到这个文档。

参考文档，

cachettlinseconds：整数

CacheTtlInSeconds
The time-to-live (TTL) period, in seconds, that specifies how long API Gateway caches responses.
Required: No
Type: Integer

参考：

http://docs.aws.amazon.com/awscloudformation/latest/userguide/aws-properties-apigateway-apigateway-deployment stageScription.html

希望它有帮助。

将标头添加到云形式的方法，

ResponseParameters
Response parameters that API Gateway sends to the client that called a method. Specify response parameters as key-value pairs (string-to-Boolean maps), with a destination as the key and a Boolean as the value. Specify the destination using the following pattern: method.response.header.name, where the name is a valid, unique header name. The Boolean specifies whether a parameter is required.
Required: No
Type: Mapping of key-value pairs
