[转] python 获取本机ip地址的两种实现方法

#!/usr/bin/python  
  
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  

　　

#!/usr/bin/python  
  
def get_local_ip(ifname):  
import socket, fcntl, struct  
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)  
inet = fcntl.ioctl(s.fileno(), 0x8915, struct.pack(‘256s‘, ifname[:15]))  
ret = socket.inet_ntoa(inet[20:24])  
return ret  
print get_local_ip("eth0")
