Node.js dnsPromises.Resolver用法及代码示例

类：dnsPromises.Resolver

DNS 请求的独立解析器。

创建新的解析器使用默认服务器设置。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('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');
})();

dnsPromises API 中的以下方法可用：

• dnsPromises.getServers()
• resolver.resolve()
• resolver.resolve4()
• resolver.resolve6()
• dnsPromises.resolveAny(hostname)
• resolver.resolveCaa()
• resolver.resolveCname()
• resolver.resolveMx()
• dnsPromises.resolveNaptr(hostname)
• resolver.resolveNs()
• resolver.resolvePtr()
• dnsPromises.resolveSoa(hostname)
• dnsPromises.resolveSrv(hostname)
• resolver.resolveTxt()
• resolver.reverse()
• dnsPromises.setServers(servers)
