如何找到本地IP地址(即192.168.x。x或10.0.x.x)在Python平台独立,只使用标准库?
当前回答
import netifaces as ni
ni.ifaddresses('eth0')
ip = ni.ifaddresses('eth0')[ni.AF_INET][0]['addr']
print(ip)
这将返回你的IP地址在Ubuntu系统和MacOS。输出将是系统IP地址,如我的IP: 192.168.1.10。

[仅限Windows]如果您不想使用外部包,也不想依赖外部Internet服务器,这可能会有所帮助。这是一个代码样本,我在谷歌代码搜索和修改返回所需的信息:
def getIPAddresses():
from ctypes import Structure, windll, sizeof
from ctypes import POINTER, byref
from ctypes import c_ulong, c_uint, c_ubyte, c_char
MAX_ADAPTER_DESCRIPTION_LENGTH = 128
MAX_ADAPTER_NAME_LENGTH = 256
MAX_ADAPTER_ADDRESS_LENGTH = 8
class IP_ADDR_STRING(Structure):
pass
LP_IP_ADDR_STRING = POINTER(IP_ADDR_STRING)
IP_ADDR_STRING._fields_ = [
("next", LP_IP_ADDR_STRING),
("ipAddress", c_char * 16),
("ipMask", c_char * 16),
("context", c_ulong)]
class IP_ADAPTER_INFO (Structure):
pass
LP_IP_ADAPTER_INFO = POINTER(IP_ADAPTER_INFO)
IP_ADAPTER_INFO._fields_ = [
("next", LP_IP_ADAPTER_INFO),
("comboIndex", c_ulong),
("adapterName", c_char * (MAX_ADAPTER_NAME_LENGTH + 4)),
("description", c_char * (MAX_ADAPTER_DESCRIPTION_LENGTH + 4)),
("addressLength", c_uint),
("address", c_ubyte * MAX_ADAPTER_ADDRESS_LENGTH),
("index", c_ulong),
("type", c_uint),
("dhcpEnabled", c_uint),
("currentIpAddress", LP_IP_ADDR_STRING),
("ipAddressList", IP_ADDR_STRING),
("gatewayList", IP_ADDR_STRING),
("dhcpServer", IP_ADDR_STRING),
("haveWins", c_uint),
("primaryWinsServer", IP_ADDR_STRING),
("secondaryWinsServer", IP_ADDR_STRING),
("leaseObtained", c_ulong),
("leaseExpires", c_ulong)]
GetAdaptersInfo = windll.iphlpapi.GetAdaptersInfo
GetAdaptersInfo.restype = c_ulong
GetAdaptersInfo.argtypes = [LP_IP_ADAPTER_INFO, POINTER(c_ulong)]
adapterList = (IP_ADAPTER_INFO * 10)()
buflen = c_ulong(sizeof(adapterList))
rc = GetAdaptersInfo(byref(adapterList[0]), byref(buflen))
if rc == 0:
for a in adapterList:
adNode = a.ipAddressList
while True:
ipAddr = adNode.ipAddress
if ipAddr:
yield ipAddr
adNode = adNode.next
if not adNode:
break
用法:
>>> for addr in getIPAddresses():
>>> print addr
192.168.0.100
10.5.9.207
由于它依赖于windll,这将只在Windows上工作。
简单而甜蜜!
def getip():
import socket
hostname= socket.gethostname()
ip=socket.gethostbyname(hostname)
return(ip)
这不是很Pythonic,但它在Windows上可靠地工作。
def getWinIP(version = 'IPv4'):
import subprocess
if version not in ['IPv4', 'IPv6']:
print 'error - protocol version must be "IPv4" or "IPv6"'
return None
ipconfig = subprocess.check_output('ipconfig')
my_ip = []
for line in ipconfig.split('\n'):
if 'Address' in line and version in line:
my_ip.append(line.split(' : ')[1].strip())
return my_ip
print getWinIP()
是的,这是一种黑客行为,但有时我不想事后怀疑操作系统,直接使用内置的和有效的操作系统就行了。
Netifaces可通过PIP和easy_install获得。(我知道,它不在基础,但它可能值得安装。)
Netifaces在不同平台上确实有一些奇怪之处:
localhost/loop-back接口可能并不总是包含在内(Cygwin)。 地址按协议列出(例如IPv4, IPv6),协议按接口列出。在某些系统(Linux)上,每个协议-接口对都有自己的关联接口(使用interface_name:n表示法),而在其他系统(Windows)上,单个接口将有每个协议的地址列表。在这两种情况下都有一个协议列表,但它可能只包含一个元素。
下面是一些netifaces代码:
import netifaces
PROTO = netifaces.AF_INET # We want only IPv4, for now at least
# Get list of network interfaces
# Note: Can't filter for 'lo' here because Windows lacks it.
ifaces = netifaces.interfaces()
# Get all addresses (of all kinds) for each interface
if_addrs = [netifaces.ifaddresses(iface) for iface in ifaces]
# Filter for the desired address type
if_inet_addrs = [addr[PROTO] for addr in if_addrs if PROTO in addr]
iface_addrs = [s['addr'] for a in if_inet_addrs for s in a if 'addr' in s]
# Can filter for '127.0.0.1' here.
上面的代码没有将地址映射回接口名(对于动态生成ebtables/iptables规则很有用)。所以这里有一个版本,它将上述信息和接口名称保存在一个元组中:
import netifaces
PROTO = netifaces.AF_INET # We want only IPv4, for now at least
# Get list of network interfaces
ifaces = netifaces.interfaces()
# Get addresses for each interface
if_addrs = [(netifaces.ifaddresses(iface), iface) for iface in ifaces]
# Filter for only IPv4 addresses
if_inet_addrs = [(tup[0][PROTO], tup[1]) for tup in if_addrs if PROTO in tup[0]]
iface_addrs = [(s['addr'], tup[1]) for tup in if_inet_addrs for s in tup[0] if 'addr' in s]
而且,不,我不喜欢列表理解。这些天我的大脑就是这么运转的。
下面的代码段将全部打印出来:
from __future__ import print_function # For 2.x folks
from pprint import pprint as pp
print('\nifaces = ', end='')
pp(ifaces)
print('\nif_addrs = ', end='')
pp(if_addrs)
print('\nif_inet_addrs = ', end='')
pp(if_inet_addrs)
print('\niface_addrs = ', end='')
pp(iface_addrs)
享受吧!
from netifaces import interfaces, ifaddresses, AF_INET
iplist = [ifaddresses(face)[AF_INET][0]["addr"] for face in interfaces() if AF_INET in ifaddresses(face)]
print(iplist)
['10.8.0.2', '192.168.1.10', '127.0.0.1']
