VueJs 权限管理

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="width: 70px;margin-left: -5px;padding:10px 0;" type="text">
<Icon :size="20" :color="iconColor" :type="item.icon"></Icon>
</Button>
<DropdownMenu style="width: 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="width: 70px;margin-left: -5px;padding:10px 0;" type="text">
<Icon :size="20" :color="iconColor" :type="item.icon"></Icon>
</Button>
<DropdownMenu style="width: 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。
