如何在Typescript中验证Ip地址？

function validateIPAddress(ip: string): boolean {
  const pattern =
    /^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/;
  return pattern.test(ip);
}

const ipAddress = '192.168.0.1';
console.log(validateIPAddress(ipAddress)); // true

npm install ip

import * as ip from 'ip';

function validateIPAddress(ipAddress: string): boolean {
  return ip.isV4Format(ipAddress) || ip.isV6Format(ipAddress);
}

const ipAddress = '192.168.0.1';
console.log(validateIPAddress(ipAddress)); // true
