python 获取本机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')环回地址
#get_ip_address('eth0')主机ip地址

windows:

import re,urllib2
from subprocess import Popen, PIPE
    print "本机的私网IP地址为：" + re.search('\d+\.\d+\.\d+\.\d+',Popen('ipconfig', stdout=PIPE).stdout.read()).group(0)
    print "本机的公网IP地址为：" + re.search('\d+\.\d+\.\d+\.\d+',urllib2.urlopen("http://www.7qiao.cn/ip.php").read()).group(0)
