python获取本机ip地址的两个方法

代码如下:

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

代码如下:

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")
