如何在Node.js中设置DNS服务器解析查询?

问题描述

我正在尝试在Node.js解析查询中设置Google DNS服务器 8.8.8.8 .

I'm trying to set Google DNS server 8.8.8.8 in Node.js resolve query.

这样做的正确方法是什么?在命令行中，通常我们可以执行以下操作:

What is the correct way to do so? In command line usually we can do the following:

$ nslookup stackoverflow.com 8.8.8.8

Server:     8.8.8.8
Address:    8.8.8.8#53

Non-authoritative answer:
Name:   stackoverflow.com
Address: 151.101.1.69
Address: 151.101.65.69
Address: 151.101.129.69
Address: 151.101.193.69

但是不清楚如何在Node.js中实现相同的方法

But its not quite clear how to make same approach in Node.js

require('dns').resolve('stackoverflow.com', function (err, addresses) {
  console.log(err, addresses);
});

// => null [ '151.101.1.69', '151.101.65.69', '151.101.129.69', '151.101.193.69' ]

推荐答案

从nodejs文档: https://nodejs.org/api/dns.html#dns_dns_setservers_servers

From nodejs doc: https://nodejs.org/api/dns.html#dns_dns_setservers_servers

dns.setServers([
   '4.4.4.4',
   '[2001:4860:4860::8888]',
]);
