dnsPromises.resolveNaptr(hostname)


使用域名系统协议为 hostname 解析基于正则表达式的记录(NAPTR 记录)。 当成功时,Promise 使用具有以下属性的对象数组进行解决:

  • flags
  • service
  • regexp
  • replacement
  • order
  • preference
{
  flags: 's',
  service: 'SIP+D2U',
  regexp: '',
  replacement: '_sip._udp.example.com',
  order: 30,
  preference: 100
}

Uses the DNS protocol to resolve regular expression-based records (NAPTR records) for the hostname. On success, the Promise is resolved with an array of objects with the following properties:

  • flags
  • service
  • regexp
  • replacement
  • order
  • preference
{
  flags: 's',
  service: 'SIP+D2U',
  regexp: '',
  replacement: '_sip._udp.example.com',
  order: 30,
  preference: 100
}
