amazon-web-services - 使用带有查询参数的方法进行 SAM API 网关缓存

Question

使用以下 SAM 模板:

Resources:
  MyApi:
    Type: AWS::Serverless::Api
    Properties:
      StageName: Prod
      CacheClusterEnabled: true
      CacheClusterSize: '0.5'
      MethodSettings:
        - HttpMethod: GET
          CacheTtlInSeconds: 120
          ResourcePath: "/getData"
          CachingEnabled: true
      DefinitionBody:
        swagger: 2.0
        basePath: /Prod
        info:
          title: OutService
        x-amazon-apigateway-policy:
          Version: "2012-10-17"
          Statement:
            - Effect: Allow
              Principal: "*"
              Action: execute-api:Invoke
              Resource:
                - execute-api:/*/*/*
        paths:
          "/getData":
            get:
              x-amazon-apigateway-integration:
                httpMethod: POST
                type: aws_proxy
                uri:
                  Fn::Sub: arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${OutLambda.Arn}/invocations
              responses: {}
      EndpointConfiguration: PRIVATE
      Cors:
        AllowHeaders: "'*'"

现在/getData 接受查询参数，例如- /getData?path=abcd/efgh 响应 1234。

当我使用路径 /getData?path=abcd/efgh 触发 API 时，它会正确缓存 - 响应 1234。

但是，在我使用不同的查询参数触发 api 之后 - 例如/getData?path=uvw/xyz 期望响应 789 返回为第一个请求缓存的响应 - 1234。

如何确保缓存应用于具有查询参数的路径？

发出的请求序列及其各自响应的示例:

/getData?path=abcd/efgh -> 1234 在 11:01:01 返回并缓存

/getData?path=uvw/xyz -> 789 在 11:01:02 返回并缓存

/getData?path=abcd/efgh -> 1234 在 11:01:20 从缓存中返回

/getData?path=uvw/xyz -> 789 在 11:01:31 从缓存中返回

我正在尝试利用RequestParameters，然后将它们映射到CacheKeyParameters，如这两篇文章中所述 - https://medium.com/@dougmoscrop/i-set-up-api-gateway-caching-here-are-some-things-that-surprised-me-7526d954fbe6 & https://theburningmonk.com/2016/04/serverless-enable-caching-on-query-string-parameters-in-api-gateway/ ，但是这两个都使用无服务器框架，我无法弄清楚这如何适合我的模板

AWS API Gateway 控制台中的最终结果必须显示设置缓存复选框为:

我们可以这样实现:

Resources:
  MyApi:
    Type: AWS::Serverless::Api
    Properties:
      StageName: Prod
      CacheClusterEnabled: true
      CacheClusterSize: '0.5'
      MethodSettings:
        - HttpMethod: GET
          CacheTtlInSeconds: 120
          ResourcePath: "/getData"
          CachingEnabled: true
      DefinitionBody:
        swagger: 2.0
        basePath: /Prod
        info:
          title: OutService
        x-amazon-apigateway-policy:
          Version: "2012-10-17"
          Statement:
            - Effect: Allow
              Principal: "*"
              Action: execute-api:Invoke
              Resource:
                - execute-api:/*/*/*
        paths:
          "/getData":
            get:
              # ** Missing param start **
              parameters:
                - name: "path"
                  in: "query"
                  required: "false"
                  type: "string"
              # ** Missing param end **
              x-amazon-apigateway-integration:
              # ** Key is cached **
                cacheKeyParameters:
                  - method.request.querystring.path
                httpMethod: POST
                type: aws_proxy
                uri:
                  Fn::Sub: arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${OutLambda.Arn}/invocations
              responses: {}
      EndpointConfiguration: PRIVATE
      Cors:
        AllowHeaders: "'*'"
