如何使用python cdk将CloudFormation负载均衡器设置为Amazon Route53的别名目标？

Question

我在代码中尝试了以下内容

alb = aws_elasticloadbalancingv2.CfnLoadBalancer(
            self,
            id=self.id,
            name=load_balancer_name,
            load_balancer_attributes=cfn_alb_props,
            security_groups=security_groups,
            subnets=self.subnets
)

target = aws_route53.RecordTarget.from_alias(aws_route53_targets.LoadBalancerTarget(alb))

hosted_zone = aws_route53.HostedZone.from_hosted_zone_attributes(self, "route53-hosted-zone-id", 
              hosted_zone_id=hosted_zone_id, zone_name="route53-hosted-zone-name")

aws_route53.ARecord(self, 'AliasRecord', 
            target=target, 
            zone=hosted_zone)

我在控制台上遇到以下错误

jsii.errors.JavaScriptError: 
  Error: Resolution error: Supplied properties not correct for "CfnRecordSetProps"
    aliasTarget: supplied properties not correct for "AliasTargetProperty"
      dnsName: required but missing
      hostedZoneId: required but missing.

我猜我在创建alb时缺少了dnsName和hostedZoneId吗？我尝试查看AWS CDK参考指南中有关如何将其传递给我的更多信息，但是它并没有完全有用，并且在任何地方都没有这样做的示例
