通过 os.networkInterfaces 获取本地Ip

| vue 项目中使用

  1. 新建 config/getIp.js

     const os = require('os');
 function getNetworkIp() {
     let needHost = ''; // 打开的host
     try {
         // 获得网络接口列表
         let network = os.networkInterfaces();
         console.log("getNetworkIp -> network", network) // 打印结果见最下方
         for (let dev in network) {
             let iface = network[dev];
             for (let i = 0; i < iface.length; i++) {
                 let alias = iface[i];
                 if (alias.family === 'IPv4' && alias.address !== '127.0.0.1' && !alias.internal) {
                     needHost = alias.address;
                 }
             }
         }
     } catch (e) {
         needHost = 'localhost';
     }
     return needHost;
 }
 module.exports = getNetworkIp

  2. config/index 中引用

const Ip = require('./getIp')
module.exports = {
    dev: { 
        host: Ip(), 
        port: 8080,
        // ...
    }

getNetworkIp -> network 打印结果 ：
