Golang：获取系统解析器的DNS服务器列表

问题描述：

In Ruby I can get the list of dns servers like this:

require 'resolv'
Resolv::DNS::Config.default_config_hash[:nameserver]

How to do the same in Go?

在Ruby中，我可以像这样获取dns服务器列表： p>

  需要'resolv'
Resolv :: DNS :: Config.default_config_hash [：nameserver] 
  code>  pre> 
 
 如何在Go中执行相同的操作？ p>  
  div>

The Resolver type in the net package lets you resolve DNS names but it doesn't seem to export the DNS servers it uses.

Ruby parses /etc/resolv.conf so I guess you'll have to do that yourself or see if you can find a package that does it for you.

Update: I made a small library to do sort of the same as Ruby's DNS class. Hope it helps.
