Node.js – dnsPromises.resolveAny() 方法
该方法使用DNS协议来解析所有记录（这也称为ANY或*query）。承诺是通过一个包含各种类型记录的数组来解决的。dnsPromises.resolveAny()
语法
dnsPromises.resolveAny(hostname)
参数
主机名-此参数接受要解析的主机名的输入。
示例1
创建一个名为“resolveAny.js”的文件并复制以下代码。创建文件后，使用命令“noderesolveAny.js”运行此代码，如下例所示-
//Node.js程序来演示
//dnsPromises.resolveAny()方法
//从dns模块访问promises对象
const dns = require('dns');
const dnsPromises = dns.promises;
//调用dnsPromises.resolveAny()方法
dnsPromises.resolveAny('nhooo.com').then((response) => {
console.log("记录：", response);
});输出结果C:\home\node>> node resolveAny.js
