dnsPromises.resolveAny(hostname)

• hostname <string>

使用 DNS 协议解析所有记录（也称为 ANY 或 * 查询）。 成功时，Promise 会以一个包含各种类型记录的数组形式被解析。每个对象都有一个 type 属性，用于指示当前记录的类型。根据 type，对象上还会有其他属性:

【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()
'TLSA'	Refer to dnsPromises.resolveTlsa()
'TXT'	This type of record contains an array property called entries which refers to dnsPromises.resolveTxt(), e.g. { entries: ['...'], type: 'TXT' }

以下是结果对象的示例：

【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',
