dns.resolveTxt(hostname, callback)

• hostname <string>
• callback <Function>
  • err <Error>

使用域名系统协议为 hostname 解析文本查询（TXT 记录）。 传给 callback 函数的 records 参数是可用于 hostname（例如 [ ['v=spf1 ip4:0.0.0.0 ', '~all' ] ]）的文本记录的二维数组。 每个子数组包含一条记录的 TXT 块。 根据用例，这些可以连接在一起或单独处理。

• hostname <string>
• callback <Function>
  • err <Error>
  • records <string[][]>

Uses the DNS protocol to resolve text queries (TXT records) for the hostname. The records argument passed to the callback function is a two-dimensional array of the text records available for hostname (e.g. [ ['v=spf1 ip4:0.0.0.0 ', '~all' ] ]). Each sub-array contains TXT chunks of one record. Depending on the use case, these could be either joined together or treated separately.
