dns.resolveTxt(hostname, callback)

版本历史

版本	变更
v18.0.0	将无效回调传给 `callback` 参数现在会抛出 `ERR_INVALID_ARG_TYPE` 而不是 `ERR_INVALID_CALLBACK`。
v0.1.27	新增于: v0.1.27

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

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。

Version	Changes
v18.0.0	Passing an invalid callback to the `callback` argument now throws `ERR_INVALID_ARG_TYPE` instead of `ERR_INVALID_CALLBACK`.
v0.1.27	Added in: v0.1.27

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.
