在 Mac OS X 上以编程方式查找 DNS 服务器设置 [英] Finding DNS server settings programmatically on Mac OS X

问题描述

我有一些跨平台 DNS 客户端代码，用于执行端到端 SMTP，在 Windows 上，我可以通过查看注册表找到当前的 DNS 服务器 IP 地址.在 Mac 上，我可能可以使用第一个答案中提到的 SystemConfiguration 框架，但是这样做的确切方法并不是很明显.

I have some cross platform DNS client code that I use for doing end to end SMTP and on windows I can find the current DNS server ip addresses by looking in the registry. On the Mac I can probably use the SystemConfiguration framework as mentioned in the first answer, however the exact method of doing so is not immediately obvious.

例如 SCDynamicStoreCopyDHCPInfo 返回一些动态 DHCP 相关数据，但不返回 DNS 服务器地址.

For instance SCDynamicStoreCopyDHCPInfo returns some of the dynamic DHCP related data but not the DNS server addresses.

推荐答案

它们也可以从/etc/resolv.conf

They are also available from /etc/resolv.conf
