解决 webpack-dev-server 不能使用 IP 访问

note

webpack-dev-server 不能使用 IP 访问

1、获取ip

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();    let alias = network['WLAN'];    console.log(network['WLAN']);    for (let i = 0; i < alias.length; i++) {      if (alias[i]['family'] === 'IPv4' && alias[i]['address'] !== '127.0.0.1' && !alias[i]['internal']) {        needHost = alias[i]['address'];      }    }  } catch (e) {    needHost = 'localhost';  }  return needHost;}

2、添加到config中

 host: getNetworkIp(),

3、完整配置

'use strict'// Template version: 1.2.4// see http://vuejs-templates.github.io/webpack for documentation.
const path = require('path')
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();    let alias = network['WLAN'];    console.log(network['WLAN']);    for (let i = 0; i < alias.length; i++) {      if (alias[i]['family'] === 'IPv4' && alias[i]['address'] !== '127.0.0.1' && !alias[i]['internal']) {        needHost = alias[i]['address'];      }    }  } catch (e) {    needHost = 'localhost';  }  return needHost;}module.exports = {  dev: {
    // Paths    assetsSubDirectory: 'static',    assetsPublicPath: '/',    proxyTable: {      '/api': {        target: '', // 你接口的域名        // target: '', // 你接口的域名        secure: false, // 如果是https接口，需要配置这个参数        changeOrigin: true // 如果接口跨域，需要进行这个参数配置      }    },
