从VPC中的ApiGateway调用公共ApiGateway

Question

我有两个api网关-一个公共（A），另一个在VPC（B）中，其中VPCEndpoint配置为对api网关进行调用。

VPCEndpoint配置：

  IotCoreApiGatewayVPCEndpoint:
    Type: AWS::EC2::VPCEndpoint
    Properties:
      PolicyDocument:
        Version: 2012-10-17
        Statement:
          - Effect: Allow
            Principal: "*"
            Action:
              - "execute-api:Invoke"
            Resource: !Sub arn:aws:execute-api:${AWS::Region}:${AWS::AccountId}:*
      ServiceName: !Sub com.amazonaws.${AWS::Region}.execute-api
      VpcEndpointType: Interface
      VpcId: !Ref VpcId
      PrivateDnsEnabled: true
      SecurityGroupIds:
        - !GetAtt DbSecurityGroup.GroupId
      SubnetIds:
        - !Ref PrivateSubnetAId
        - !Ref PrivateSubnetBId

api网关B正在调用api网关A，并且我收到403-禁止错误。

如果删除VPCEndpoint配置，而不是403，则会收到超时。

在没有VPC的情况下从lambda调用api网关A可以正常工作，也启用了CORS。

类似的问题在这里表达：

https://aws.amazon.com/ru/premiumsupport/knowledge-center/api-gateway-vpc-connections/

本文指出，我必须为ApiGateway设置一个Edge-Optimized Custom Domain Name，并且需要使用ACM Certificates。

有没有更简单的方法来解决此问题？我可以仅将具有安全网关ID的api网关A访问权限附加到VPCEndpoint吗？

在我向VPC添加Nat网关之前，已经阻止了对公共api网关（以及公共Internet）的访问。解决方案在这里描述-https://medium.com/@philippholly/aws-lambda-enable-outgoing-internet-access-within-vpc-8dd250e11e12
