程序运行时，router只配置登陆 首页404 等基本页面
import Main from '@/views/Main.vue'; // 不作为Main组件的子页面展示的页面单独写，如下 export const loginRouter = { path: '/login', name: 'login', meta: { title: 'Login - 登录' }, component: resolve => { require(['@/views/login.vue'], resolve); } }; export const page404 = { path: '/*', name: 'error-404', meta: { title: '404-页面不存在' }, component: resolve => { require(['@/views/error-page/404.vue'], resolve); } }; export const page403 = { path: '/403', meta: { title: '403-权限不足' }, name: 'error-403', component: resolve => { require(['@//views/error-page/403.vue'], resolve); } }; export const page500 = { path: '/500', meta: { title: '500-服务端错误' }, name: 'error-500', component: resolve => { require(['@/views/error-page/500.vue'], resolve); } }; // 作为Main组件的子页面展示但是不在左侧菜单显示的路由写在otherRouter里 export const otherRouter = { path: '/', component: Main, children: [ { path: '/', title:'Home', name: 'home_index', component: resolve => { require(['@/views/page/home.vue'], resolve); } } ] }; // 作为Main组件的子页面展示并且在左侧菜单显示的路由写在appRouter里 export const appRouter = []; // 所有上面定义的路由都要写在下面的routers里 export const routers = [ loginRouter, otherRouter, ...appRouter, page500, page403 ];
使用路由
import Vue from 'vue'; import iView from 'iview'; import Util from '../libs/util'; import VueRouter from 'vue-router'; import {routers,page404} from './router'; import Cookies from 'js-cookie'; import Main from '@/views/Main.vue'; import store from '@/store'; Vue.use(VueRouter); // 路由配置 const RouterConfig = { // mode: 'history', routes: routers }; export const router = new VueRouter(RouterConfig); router.beforeEach((to, from, next) => { iView.LoadingBar.start(); Util.title(to.meta.title); if (!Cookies.get('user') && to.name !== 'login') { // 判断是否已经登录且前往的页面不是登录页 next({ name: 'login' }); } else if (Cookies.get('user') && to.name === 'login') { // 判断是否已经登录且前往的是登录页 Util.title(); next({ name: '/' }); } else { next(); } }); router.afterEach((to) => { iView.LoadingBar.finish(); window.scrollTo(0, 0); });
登陆操作 获取菜单 将菜单存到sessionStorage中，并且把菜单存储到vuex中，因为vuex一刷新就没了，所以要放在sessionStorage中
handleSubmit() { this.$refs.loginForm.validate((valid) => { if (valid) { this.$http.post('/api/login/login', this.form) .then((data) => { this.submitPedding = false if (data.result) { window.sessionStorage.clear(); this.$http.get('/api/Common/GetMenuTree') .then((data) => { window.sessionStorage.routes = JSON.stringify(data) this.$store.commit('updateMenulist', data) // let routes = this.generateRoutesFromMenu(data) // for(var i = 0;i<routes.length;i++){ // this.$router.options.routes.push(routes[i]); // } // this.$router.addRoutes(this.$router.options.routes) Cookies.set('user', this.form.userName); this.$router.push({ path: '/' }); }) } else { switch (data.errorcode) { case 1: this.$Message.info({ content: '请输入您的账号', duration: 10, closable: true }); break; case 2: this.$Message.info({ content: '请输入您的密码', duration: 10, closable: true }); break; case 3: this.$Message.warning({ content: '用户名或密码错误', duration: 10, closable: true }); break; default: this.$Message.info({ content: '登陆失败，请稍后再试', duration: 10, closable: true }); break; } } }) } }); },

其中component存储的是字符串 需要转换为引入 vue组件 修改router.index 在使用前 修改配置
import Vue from 'vue'; import iView from 'iview'; import Util from '../libs/util'; import VueRouter from 'vue-router'; import {routers,page404} from './router'; import Cookies from 'js-cookie'; import Main from '@/views/Main.vue'; import store from '@/store'; Vue.use(VueRouter); // 路由配置 const RouterConfig = { // mode: 'history', routes: routers }; //避免刷新后 菜单清空 let menus = window.sessionStorage.routes //登录成功返回的菜单 if (menus != null && menus != "null" && menus.length != 0) { let items = JSON.parse(menus) store.commit('updateMenulist', items) let routes = generateRoutesFromMenu(items) for(var i = 0;i<routes.length;i++){ routers.push(routes[i]); } } routers.push(page404) function generateRoutesFromMenu(menu = [], routes = []) { for (let i = 0; i < menu.length; i++) { menu[i].component = require('../views/Main.vue'); for(let j = 0;j<menu[i].children.length;j++){ let filePath = menu[i].children[j].component menu[i].children[j].component = require('../views/page/' + filePath + '.vue'); } routes.push(menu[i]) } return routes } export const router = new VueRouter(RouterConfig); router.beforeEach((to, from, next) => { iView.LoadingBar.start(); Util.title(to.meta.title); if (!Cookies.get('user') && to.name !== 'login') { // 判断是否已经登录且前往的页面不是登录页 next({ name: 'login' }); } else if (Cookies.get('user') && to.name === 'login') { // 判断是否已经登录且前往的是登录页 Util.title(); next({ name: '/' }); } else { next(); } }); router.afterEach((to) => { iView.LoadingBar.finish(); window.scrollTo(0, 0); });
menu[i].children[j].component = require('../views/page/' + filePath + '.vue'); 这里 前面的路径 和后面的.vue不可少，意思是让webpack到views下面的page下面去找.vue结尾的文件。
404路由 要加到最后 否则路由先找到*的 以后的就不执行了。
store中
const app = { state: { menuList: [], routers: [ otherRouter, ...appRouter ] }, mutations: { updateMenulist (state,menu) { state.menuList = menu; } } };
左侧菜单遍历 store中的menuList
<template> <div> <template v-for="(item, index) in menuList"> <div style="text-align: center;" :key="index"> <Dropdown transfer v-if="item.children.length !== 1" placement="right-start" :key="index" @on-click="changeMenu"> <Button style=" 70px;margin-left: -5px;padding:10px 0;" type="text"> <Icon :size="20" :color="iconColor" :type="item.icon"></Icon> </Button> <DropdownMenu style=" 200px;" slot="list"> <template v-for="(child, i) in item.children"> <DropdownItem :name="child.name" :key="i"><Icon :type="child.icon"></Icon><span style="padding-left:10px;">{{ itemTitle(child) }}</span></DropdownItem> </template> </DropdownMenu> </Dropdown> <Dropdown transfer v-else placement="right-start" :key="index" @on-click="changeMenu"> <Button @click="changeMenu(item.children[0].name)" style=" 70px;margin-left: -5px;padding:10px 0;" type="text"> <Icon :size="20" :color="iconColor" :type="item.icon"></Icon> </Button> <DropdownMenu style=" 200px;" slot="list"> <DropdownItem :name="item.children[0].name" :key="'d' + index"><Icon :type="item.icon"></Icon><span style="padding-left:10px;">{{ itemTitle(item.children[0]) }}</span></DropdownItem> </DropdownMenu> </Dropdown> </div> </template> </div> </template>
至此 权限从后台读取，到前台页面展示就完成了，页面内部每次刷新 都会重新从sessionStorage中获取重新赋值。
