dnsPromises.resolveTxt(hostname)

• hostname <string>

使用 DNS 协议解析 hostname 的文本查询（TXT 记录）。成功时，Promise 会被解析为一个二维数组，包含 hostname 可用的文本记录（例如 [ ['v=spf1 ip4:0.0.0.0 ', '~all'] ]）。每个子数组包含一条记录的 TXT 块。根据使用情况，这些块可以合并在一起或单独处理。

【Uses the DNS protocol to resolve text queries (TXT records) for the hostname. On success, the Promise is resolved with 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.】
