amazon-web-services - 如何使用 cloudformation 创建私有 AWS Api 网关？

Question

我正在尝试创建 PRIVATE 类型的 AWS API 网关，
这需要一个资源策略，因为我能够从 AWS 控制台创建网关，
所以我想知道如何通过 CF 添加资源策略模板 -

以下是资源策略的大摇大摆定义 -

x-amazon-apigateway-policy:
  Version: "2012-10-17"
  Statement:
  - Effect: "Deny"
    Principal: "*"
    Action: "execute-api:Invoke"
    Resource: "arn:aws:execute-api:us-east-1:awsAccountId:xxxx/*/*/*"
    Condition:
      StringNotEquals:
        aws:sourceVpc: "vpc-xxxxx"
  - Effect: "Allow"
    Principal: "*"
    Action: "execute-api:Invoke"
    Resource: "arn:aws:execute-api:us-east-1:xxxx:xxxx/*/*/*"

如何在 CF 模板中配置它 -

AWSTemplateFormatVersion: 2010-09-09
Transform: 'AWS::Serverless-2016-10-31'
Description: G2G Api Template Stack

Resources:
   g2gPrivate:
    Type: 'AWS::ApiGateway::RestApi'
    Properties:
      Name: 'private-gw'
      EndpointConfiguration:
        Types:
          - PRIVATE

您需要在密钥下提供策略（Policy与Name.

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigateway-restapi.html#cfn-apigateway-restapi-policy

这需要以 JSON 格式提供。
