通过os.networkInterfaces();
const os = require('os'); // 获取局域网 IP 地址 function getLocalIp() { const interfaces = os.networkInterfaces(); for (const name of Object.keys(interfaces)) { for (const iface of interfaces[name]) { if (iface.family === 'IPv4' && !iface.internal) { return iface.address; } } } return '127.0.0.1'; }
