获取本机网络信息

此代码获取一下信息：

网卡名称(NicName)

IP地址（IPAddr）

子网掩码（IPNetmask）

网关地址（Gateway）

外网出口地址（outsideIp）

需要用pip3安装 netifaces、requests、re三个外部模块

需要连接外部URL“http://2019.ip138.com/ic.asp”

代码如下：

 

#!/usr/bin/python3

import netifaces

import requests

import re

import os

import socket

 

HostName = socket.gethostname()

UserName = os.getlogin()

 

url = "http://2019.ip138.com/ic.asp"

html = requests.get(url).text

str1 = str(re.findall(r'[0-9]+(?:\.[0-9]+){3}',html))

outsideIp = str1[2:-2]

 

Gateway = netifaces.gateways()['default'][netifaces.AF_INET][0]

NicName = netifaces.gateways()['default'][netifaces.AF_INET][1]

 

for interface in netifaces.interfaces():

if interface == NicName:

NicMacAddr = netifaces.ifaddresses(interface)[netifaces.AF_LINK][0]['addr']

IPAddr = netifaces.ifaddresses(interface)[netifaces.AF_INET][0]['addr']

IPNetmask = netifaces.ifaddresses(interface)[netifaces.AF_INET][0]['netmask']

 

 

print("Host Name is:", HostName)

print("User Name is:", UserName)

print("NIC Name is:", NicName)

print("IP Address is:", IPAddr)

print("Mask of IP is:", IPNetmask)

print("Mac address is:", NicMacAddr)

print("Gateway is:", Gateway)

print("outside IP is:", outsideIp)

 

输出结果：
