1、Windows下2种方法:
1.
使用拨号上网的话,一般都有一个本地ip和一个外网ip,使用python可以很容易的得到这两个ip
使用gethostbyname和gethostbyname_ex两个函数可以实现
import socket
localIP = socket.gethostbyname(socket.gethostname()) #这个得到本地ip
print "local ip:%s "%localIP
ipList = socket.gethostbyname_ex(socket.gethostname())
for i in ipList:
if i != localIP:
print "external IP:%s"%i
2.
import socket
myname = socket.getfqdn(socket.gethostname())
myaddr = socket.gethostbyname(myname)
2、还有一种Linux下的方法可以用的是:
Uses the Linux SIOCGIFADDR ioctl to find the IP address associated with a network interface, given the name of that interface, e.g. "eth0". The address is returned as a string containing a dotted quad.
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')
'127.0.0.1'
>>> get_ip_address('eth0')
'38.113.228.130'
3、跨平台解决方案:
通用化,不用第三方包的代码:
def get_ip_address(ifname=None):
if sys.platform == 'win32':
return socket.getaddrinfo(socket.gethostname(), None, socket.AF_INET, socket.SOCK_DGRAM)[-1][4][0]
else:
import fcntl
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])
