Python获取本机公网IP（windows、Linux下通用）

class Getmyip:
    def getip(self):
        try:
            myip = self.visit("http://www.ip138.com/ip2city.asp")
        except:
            try:
                myip = self.visit("http://www.bliao.com/ip.phtml")
            except:
                try:
                    myip = self.visit("http://www.whereismyip.com/")
                except:
                    myip = "So sorry!!!"
        return myip
    def visit(self,url):
        opener = urllib2.urlopen(url)
        if url == opener.geturl():
            str = opener.read()
        return re.search('\d+\.\d+\.\d+\.\d+',str).group(0)
getmyip = Getmyip()
localip = getmyip.getip()
print localip

二、Linux下获取本地的IP

# -*- coding:UTF-8 -*-
import os

ip = os.popen("/sbin/ifconfig | grep 'inet addr' | awk '{print $2}'").read()
ip = ip[ip.find(':')+1:ip.find('\n')]
print ip
