1. 先在router/index.js文件中配置好不同端口跳转的路由

import Vue from 'vue'
import VueRouter from 'vue-router'

// 解决ElementUI导航栏中的vue-router在3.0版本以上重复点菜单报错问题
const originalPush = VueRouter.prototype.push
VueRouter.prototype.push = function push(location) {
    return originalPush.call(this, location).catch(err => err)
}

Vue.use(VueRouter);

const routes = [
    {
        path: '/pc/index',
        component: () => import('@/views/pc')
      },
    {
        path: '/mb/index',
        component: () => import('@/views/mb'),
    }
]


const router = new VueRouter({
    mode: 'history',
    base: process.env.BASE_URL,
    routes,
    //vue页面跳转，不保留滚动位置，回到顶部
    scrollBehavior(to, from, saveTop) {
        if (saveTop) {
            return saveTop;
        } else {
            return {x: 0, y: 0}
        }
    }
});

export default router

在App.vue中做出判断，并跳转路由

mounted () {
    // 根据不同路由跳转不同页面
    if (this._isMobile()) {
      console.log('手机端')
      this.$router.replace('/mb/index')
    } else {
      console.log('pc端')
      this.$router.replace('/pc/index')
    }
  },
  methods: {
    // 判断是否是手机端，如果是，返回true
    _isMobile () {
      let flag = navigator.userAgent.match(/(phone|pad|pod|iPhone|iPod|ios|iPad|Android|Mobile|BlackBerry|IEMobile|MQQBrowser|JUC|Fennec|wOSBrowser|BrowserNG|WebOS|Symbian|Windows Phone)/i)
      return flag
    }
  }
