dnsPromises.resolveTxt(hostname)


使用域名系统协议为 hostname 解析文本查询(TXT 记录)。 当成功时,Promise 使用可用于 hostname(例如 [ ['v=spf1 ip4:0.0.0.0 ', '~all' ] ])的文本记录的二维数组进行解决。 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。

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.
