Question

我在CloudFormation模板中描述了我的AWS资源，并面临下一个问题-我已通过HTTPS协议订阅了SNS。使用该订阅，我通过API Gateway链接了CloudWatch警报的SNS主题，该主题将这些警报转发到Slack webhook。在我的CloudFormation模板中，我已经描述了API网关元素（REST API，资源和方法）：

Resources:
  AlarmRestApi:
    Type: "AWS::ApiGateway::RestApi"
    Properties:
      Name: "sns-to-slack"
      Description: "REST API for forwarding CloudWatch alarms to Slack"

  SlackAlarmsResource:
    Type: "AWS::ApiGateway::Resource"
    Properties:
      RestApiId: !Ref "AlarmRestApi"
      ParentId: !GetAtt "AlarmRestApi.RootResourceId"
      PathPart: "slack-alarms"

  AlarmRestApiStage:
    Type: "AWS::ApiGateway::Stage"
    Properties:
      DeploymentId: !Ref "RestApiDeployment"
      RestApiId: !Ref "AlarmRestApi"
      StageName: "dev"
  ...

当前，我描述了SNS主题和订阅，但无法获取'SlackAlarmsResource'的PathPart属性，以避免在订阅模板中对其进行硬编码。具有硬编码的资源值，看起来：

CloudWatchAlarmsTopic:
    Type: AWS::SNS::Topic
    Properties:
      DisplayName: "cloudwatch-alarms"
      TopicName: "cloudwatch-alarms"

  CloudWatchAlarmsSubcscription:
    Type: "AWS::SNS::Subscription"
    Properties:
      TopicArn: !Ref "CloudWatchAlarmsTopic"
      Endpoint: !Sub "https://${AlarmRestApi}.execute-api.${AWS::Region}.amazonaws.com/${AlarmRestApiStage}/slack-alarms"
      Protocol: https
      RawMessageDelivery: true

如何在SNS订阅终结点属性中获取API网关资源的PathPart值（“松弛警报”）？
