获取本机的ip地址、子网掩码、网关 使用python实现

在Python中，我们可以利用os模块和socket模块来获取本地计算机的IP地址、子网掩码和默认网关。以下是简单的示例代码：

import os
import subprocess

def get_network_info():
    # 获取IP地址
    ip_address = subprocess.check_output(['hostname', '-I']).decode('utf-8').split()[0]
    
    # 获取子网掩码
    ipconfig_cmd = 'ipconfig | findstr /B "IPv4 Address" | findstr /B "Subnet Mask"'
    subnet_mask = subprocess.check_output(ipconfig_cmd, shell=True).decode('utf-8').split()[-1][:-1]  # 去除换行符和括号
    
    # 获取默认网关
    gateway_cmd = 'route -n | findstr "Default Gateway"'
    gateway_output = subprocess.check_output(gateway_cmd, shell=True).decode('utf-8')
    gateway = None
    for line in gateway_output.split('\n'):
        if 'Default Gateway' in line:
            gateway = line.strip().split()[1]

    return ip_address, subnet_mask, gateway

# 调用函数并打印结果
ip, subnet, gw = get_network_info()
print(f"IP 地址: {ip}")
print(f"子网掩码: {subnet}")
print(f"网关: {gw}")
