如何扭曲读取/ etc / hosts？

Question

默认情况下，Twisted在连接到Linux系统上的网站时会读取/etc/hosts。我只是想知道哪个扭曲文件选择/etc/hosts，所以我可以进入并将其更改为我选择的文件？

Answer 1

您正在寻找的代码位于Resolver Object line 621。如果要更改您在所需主机文件中传递的解析程序的行为，如下所示。

from twisted.names import client
from twisted.internet import reactor

def do_lookup(domain):
    hosts = "/tmp/example"
    resolver = client.createResolver(servers=None, resolvconf=None, hosts="/tmp/example")
    d = resolver.getHostByName(domain)
    d.addBoth(lookup_done)

def lookup_done(result):
    print(result)
    reactor.stop()

domain = b'twistfoo.com'
reactor.callLater(0, do_lookup, domain)
reactor.run()
