Linux下Python获取IP地址的代码

获取服务器IP，如果有公网地址就取公网地址，没有公网地址就取私网网址
下面是之前我用shell来获取本地IP脚本：

IP=`ifconfig | grep 'inet addr:' | cut -d: -f2 | grep -v ^10\. | grep -v ^192\.168 | grep -v ^172\. | \
grep -v ^127\. | awk '{print $1}' | awk '{print;exit}'`
 
[ ! -n "$IP" ] && IP=`ifconfig | grep 'inet addr:' | cut -d: -f2 | grep -v ^127\. | \
awk '{print $1}' | awk '{print;exit}'`

Python版：get_local_ip.py：

#!/usr/bin/env python
import socket
def Get_local_ip():
 """
 Returns the actual ip of the local machine.
 This code figures out what source address would be used if some traffic
 were to be sent out to some well known address on the Internet. In this
 case, a Google DNS server is used, but the specific address does not
 matter much. No traffic is actually sent.
 """
 try:
  csock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
  csock.connect(('8.8.8.8', 80))
  (addr, port) = csock.getsockname()
  csock.close()
  return addr
 except socket.error:
  return "127.0.0.1"
 
if __name__ == "__main__":
 local_IP = Get_local_ip() 
 print local_IP

有公网地址直接获取，没有公网地址就获取网关地址（用于判断IP地址的地理位置）：get_public_ip.py

#!/usr/bin/env python
import re,urllib2
class Get_public_ip:
 def getip(self):
  try:
   myip = self.visit("http://www.whereismyip.com/")
  except:
   try:
    myip = self.visit("http://www.ip138.com/ip2city.asp")
   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)
 
if __name__ == "__main__":
 getmyip = Get_public_ip()
 print getmyip.getip()

判断服务器IP地理位置： get_ip_area.py

#!/usr/bin/env python
#coding:utf-8
try:
 import sys,urllib2,json
 apiurl = "http://ip.taobao.com/service/getIpInfo.php?ip=%s" % sys.argv[1] 
 content = urllib2.urlopen(apiurl).read()
 data = json.loads(content)['data']
 code = json.loads(content)['code']
 if code == 0:
  print data['country_id']
 else:
  print data
except:
 print "Usage:%s IP" % sys.argv[0]
