dnsPromises.resolveSoa(hostname)


使用域名系统协议来解析 hostname 的起始规范记录(SOA 记录)。 当成功时,Promise 使用具有以下属性的对象进行解决:

  • nsname
  • hostmaster
  • serial
  • refresh
  • retry
  • expire
  • minttl
{
  nsname: 'ns.example.com',
  hostmaster: 'root.example.com',
  serial: 2013101809,
  refresh: 10000,
  retry: 2400,
  expire: 604800,
  minttl: 3600
}

Uses the DNS protocol to resolve a start of authority record (SOA record) for the hostname. On success, the Promise is resolved with an object with the following properties:

  • nsname
  • hostmaster
  • serial
  • refresh
  • retry
  • expire
  • minttl
{
  nsname: 'ns.example.com',
  hostmaster: 'root.example.com',
  serial: 2013101809,
  refresh: 10000,
  retry: 2400,
  expire: 604800,
  minttl: 3600
}
