Node.js dns dnsPromises.resolveAny(hostname)

新增于: v10.6.0

  • hostname < string>

Uses the DNS protocol to resolve all records (also known as ANY or * query). On success, the Promise is resolved with an array containing various types of records. Each object has a property type that indicates the type of the current record. And depending on the type, additional properties will be present on the object:

Type Properties
‘A’ address/ttl
‘AAAA’ address/ttl
‘CNAME’ value
‘MX’ Refer to dnsPromises.resolveMx()
‘NAPTR’ Refer to dnsPromises.resolveNaptr()
‘NS’ value
‘PTR’ value
‘SOA’ Refer to dnsPromises.resolveSoa()
‘SRV’ Refer to dnsPromises.resolveSrv()
‘TXT’ This type of record contains an array property called entries which refers to dnsPromises.resolveTxt(), e.g. { entries: ['…'], type: ‘TXT’ }

Here is an example of the result object:

[ { type: 'A', address: '127.0.0.1', ttl: 299 },
  { type: 'CNAME', value: 'example.com' },
  { type: 'MX', exchange: 'alt4.aspmx.l.example.com', priority: 50 },
  { type: 'NS', value: 'ns1.example.com' },
  { type: 'TXT', entries: [ 'v=spf1 include:_spf.example.com ~all' ] },
  { type: 'SOA',
    nsname: 'ns1.example.com',
    hostmaster: 'admin.example.com',
    serial: 156696742,
    refresh: 900,
    retry: 900,
    expire: 1800,
    minttl: 60 } ]
