python 擷取主機ip

linux：

import socket  import fcntl  import struct  def get_ip_address(ifname):      s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)      return socket.inet_ntoa(fcntl.ioctl(          s.fileno(),          0x8915, # SIOCGIFADDR          struct.pack('256s', ifname[:15])      )[20:24])  #get_ip_address('lo')迴路位址  #get_ip_address('eth0')主機ip地址 

windows：

import re,urllib2  from subprocess import Popen, PIPE  print "原生私網IP地址為：" + re.search('/d+/./d+/./d+/./d+',Popen('ipconfig', stdout=PIPE).stdout.read()).group(0)  print "原生公網IP地址為：" + re.search('/d+/./d+/./d+/./d+',urllib2.urlopen("http://www.whereismyip.com").read()).group(0)
