Question

我正在尝试创建PRIVATE类型的AWS API网关，
这需要一项资源策略，因为我可以从AWS控制台创建网关，因此具有该策略，
我想知道如何通过CF模板添加资源策略-

以下是对资源策略的严格定义-

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模板中进行配置-

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

参考-

您需要在与Policy相同级别的密钥（称为Name）下提供策略。

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。

              "Resource": "arn:aws:execute-api:us-east-1:${AWS::AccountId}:*/*/*/*",
              "Condition": {
                "StringNotEquals": {
                  "aws:sourceVpc": "vpc-xxxxx"
                }
              }
            },
            {
              "Effect": "Allow",
              "Principal": "*",
              "Action": "execute-api:Invoke",
              "Resource": "arn:aws:execute-api:us-east-1:${AWS::AccountId}:*/*/*/*"
            }
          ]
        }

如何使用cloudformation创建私有AWS Api网关？
