Node.js dns.Resolver用法及代码示例

类：dns.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');
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', (err, addresses) => {
  // ...
});

node:dns 模块中的以下方法可用：

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