如何在Python中解析SRV记录？

Question

不依赖本机库的东西会更好.

Answer 1

使用dnspython：

>>> import dns.resolver
>>> domain='jabberzac.org'
>>> srvInfo = {}
>>> srv_records=dns.resolver.query('_xmpp-client._tcp.'+domain, 'SRV')
>>> for srv in srv_records:
...     srvInfo['weight']   = srv.weight
...     srvInfo['host']     = str(srv.target).rstrip('.')
...     srvInfo['priority'] = srv.priority
...     srvInfo['port']     = srv.port
... 
>>> print srvInfo
{'priority': 0, 'host': 'xmpp.jabberzac.org', 'port': 5222, 'weight': 0}

Answer 2

twisted有一个很好的纯python实现,请参见twisted.names来源(尤其是dns.py).如果您不能使用他们的所有代码,也许您可​​以Record_SRV从该文件中提取和重新调整他们的类.

你可以试试dnspython库:
