类：dns.Resolver

【Class: dns.Resolver】

新增于: v8.3.0

域名系统请求的独立解析器。

【An independent resolver for DNS requests.】

创建一个新的解析器会使用默认的服务器设置。使用 resolver.setServers() 设置解析器使用的服务器不会影响其他解析器：

【Creating a new resolver uses the default server settings. Setting the servers used for a resolver using resolver.setServers() does not affect other resolvers:】

import { Resolver } from 'node:dns';
const resolver = new Resolver();
resolver.setServers(['4.4.4.4']);

// This request will use the server at 4.4.4.4, independent of global settings.
resolver.resolve4('example.org', (err, addresses) => {
  // ...
});const { Resolver } = require('node:dns');
const resolver = new Resolver();
resolver.setServers(['4.4.4.4']);

// This request will use the server at 4.4.4.4, independent of global settings.
resolver.resolve4('example.org', (err, addresses) => {
  // ...
});
