用python获取本机IP地址[in linux]

用python获取本机IP地址[in  Linux]

方法一：【最好的一个，<推荐>】

可以不必知道使用的是哪个网络设备，十分方便的获得正在使用的IP地址！

#!/usr/bin/env python

import socket

def get_my_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__":

    print get_my_ip()

方法二：【最灵活的一个】

需要指明此时正在使用的网络设备名！

#!/usr/bin/env 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])

Local_ip=get_ip_address("xxx")#xxx表示网络设备名

print Local_ip
