类：dnsPromises.Resolver

🌐 Class: dnsPromises.Resolver

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:

const { Resolver } = require('node:dns').promises;
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').then((addresses) => {
  // ...
});

// Alternatively, the same code can be written using async-await style.
(async function() {
  const addresses = await resolver.resolve4('example.org');
})(); 拷贝
