dnsPromises.Resolver 类

新增于: v10.6.0

域名系统请求的独立解析器。

创建新的解析器使用默认的服务器设置。使用 resolver.setServers() 设置用于解析器的服务器不会影响其他解析器：

const { Resolver } = require('dns').promises;
const resolver = new Resolver();
resolver.setServers(['4.4.4.4']);

// 此请求将使用 4.4.4.4 的服务器，与全局设置无关。
resolver.resolve4('example.org').then((addresses) => {
  // ...
});

// 或者，可以使用 async-await 风格编写相同的代码。
(async function() {
  const addresses = await resolver.resolve4('example.org');
})();

来自 dnsPromises API 的以下方法可用：

Added in: v10.6.0

An independent resolver for DNS requests.

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('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');
})();

The following methods from the dnsPromises API are available:
