vue-element-template 设置权限管理配置文件 \ vue用户权限管理

最近使用vue-element-template模板做系统时，需要实现用户权限管理，通过后端传来的roles字段来判断不同用户的身份，不同用户显示不同的侧边栏，下面是配置方法：

0.需要配置的文件有：

src/router
src/store/modules/permission.js (没有就添加)
src/store/modules/user.js
src/store/index
src/permission.js
src/store/getters.js

1.首先修改 src/router中代码：

把需要权限的加在 asyncRoutes 里面，相应权限就用roles: ['admin']放不同的用户类型来控制。

constantRoutes里面放静态路由,所有人可见

具体参考下面代码：

import Vue from 'vue'
import Router from 'vue-router'
// 路由是个插件，需要use
Vue.use(Router)
// 引入layout组件，一级路由出口中，匹配layout组件
import Layout from '@/layout'// 静态路由,所有人可见
export const constantRoutes = [{path: '/login',component: () => import('@/views/login/index'),// hidden为true表示在侧边栏不显示hidden: true},{path: '/404',component: () => import('@/views/404'),hidden: true},{path: '/',component: Layout,redirect: '/dashboard',// 二级路由children: [{path: 'dashboard',name: 'Dashboard',component: () => import('@/views/dashboard/index'),meta: { title: '首页', icon: 'dashboard' }}]},// 404 page must be placed at the end !!!{ path: '*', redirect: '/404', hidden: true }
]//相应权限人员可见
export const asyncRoutes = [{path:'/patentupload',component:Layout,name:'Patentupload',meta:{ title: '专利上传', icon: 'el-icon-s-promotion',roles: ['admin'] },children: [{path: 'singleupload',name: 'Singleupload',component: () => import('@/views/patentupload/singleload'),meta: { title: '单条专利上传',roles: ['admin'] }},{path: 'multipleload',name: 'Multipleload',component: () => import('@/views/patentupload/multipleload'),meta: { title: '多条专利上传',roles: ['admin'] }},]  },{path:'/expertrate',component:Layout,name:'Expertrate',meta:{ title: '专家打分系统', icon: 'el-icon-notebook-2',roles: ['editor'] },children: [{path: 'unratedpatents',name: 'Unratedpatents',component: () => import('@/views/expertrate/unratedpatents'),meta: { title: '未打分专利',roles: ['editor'] }},{path: 'ratedpatents',name: 'Ratedpatents',component: () => import('@/views/expertrate/ratedpatents'),meta: { title: '已打分专利',roles: ['editor'] }},{path: 'rate',name: 'Rate',component: () => import('@/views/expertrate/rate'),meta: { title: '打分界面',roles: ['editor'] }},]},
]// 创建一个路由对象
const createRouter = () => new Router({// mode: 'history', // require service supportscrollBehavior: () => ({ y: 0 }),routes: constantRoutes
})const router = createRouter()// Detail see: https://github.com/vuejs/vue-router/issues/1234#issuecomment-357941465
export function resetRouter() {const newRouter = createRouter()router.matcher = newRouter.matcher // reset router
}export default router

2. src/store/modules/permission.js (没有就添加)

generateRoutes函数来控制你设置的每个用户的判断操作，如果有超过两个的用户就继续添加ifelse。代码如下：

import { asyncRoutes, constantRoutes } from '@/router'// 筛选路由
// 匹配权限
function hasPermission( roles, route) {// 在路由上找的到 route.mate 和 route.mate.rolesif (route.meta && route.meta.roles){return roles.some(role => route.meta.roles.includes(role))}else{return true}
}// 通过递归过滤异步路由表export function filterAsyncRoutes( routes, roles){// 装筛选出来的路由const res = [] routes.forEach(route =>{const tmp = { ...route }if(hasPermission(roles, tmp)){if(tmp.children){tmp.children = filterAsyncRoutes(tmp.children, roles)}res.push(tmp)}})return res
}const state = {routes: [],addRoutes: []
}const mutations = {SET_ROUTES: (state, routes) => {state.addRoutes = routesstate.routes = constantRoutes.concat(routes) // 将过滤的路由和国定的路由存起来}
}// 筛选
const actions = {generateRoutes({ commit }, roles){return new Promise(resolve =>{let accessedRoutes// 路由是否为 admin, 有直接全部显示if(roles.includes('admin')){accessedRoutes = filterAsyncRoutes(asyncRoutes, roles)// accessedRoutes = asyncRoutes || []console.log('走了这里1 ',accessedRoutes)console.log('asyncRoutes ',asyncRoutes)}else{// 过滤路由accessedRoutes = filterAsyncRoutes(asyncRoutes, roles)console.log('走了这里2 ')}commit('SET_ROUTES', accessedRoutes)resolve(accessedRoutes)})}
}export default {namespaced: true,state,mutations,actions
}

3.src/store/modules/user.js 代码如下：

import { login, logout, getInfo } from '@/api/user'
import { getToken, setToken, removeToken } from '@/utils/auth'
import { resetRouter } from '@/router'const getDefaultState = () => {return {token: getToken(),name: '',avatar: '',roles:[], //权限设置introduction:'', // 新增}
}const state = getDefaultState()const mutations = {RESET_STATE: (state) => {Object.assign(state, getDefaultState())},SET_TOKEN: (state, token) => {state.token = token},// 新增SET_INTRODUCTION: (state, introduction) => { state.introduction = introduction},SET_NAME: (state, name) => {state.name = name},SET_AVATAR: (state, avatar) => {state.avatar = avatar},//权限设置SET_ROLES: (state, roles) => {state.roles = roles}}const actions = {// user loginlogin({ commit }, userInfo) {const { username, password } = userInfo// let result= await login({username:username.trim(),password:passwora});return new Promise((resolve, reject) => {login({ username: username.trim(), password: password }).then(response => {const { data } = responsecommit('SET_TOKEN', data.token)setToken(data.token)resolve()}).catch(error => {reject(error)})})},// get user infogetInfo({ commit, state }) {return new Promise((resolve, reject) => {getInfo(state.token).then(response => {const { data } = responseif (!data) {return reject('Verification failed, please Login again.')}// const { name, avatar } = dataconst {roles, name, avatar, introduction } = data//权限设置// 必须保证不是一个空的数组if(!roles || roles.length<=0 ){//权限设置reject('getInfo: roles must be a non-null array')//权限设置}//权限设置console.log(roles)//权限设置// 存储值commit('SET_NAME', name)commit('SET_ROLES', roles) //权限设置commit('SET_AVATAR', avatar)commit('SET_INTRODUCTION', introduction)//权限设置resolve(data)}).catch(error => {reject(error)})})},// user logoutlogout({ commit, state }) {return new Promise((resolve, reject) => {logout(state.token).then(() => {commit('SET_TOKEN', '')//权限设置commit('SET_ROLES', []) //权限设置removeToken() // must remove  token  firstresetRouter()commit('RESET_STATE')resolve()}).catch(error => {reject(error)})})},// remove tokenresetToken({ commit }) {return new Promise(resolve => {commit('SET_TOKEN', '')//权限设置commit('SET_ROLES', []) //权限设置removeToken() // must remove  token  firstcommit('RESET_STATE')resolve()})}
}export default {namespaced: true,state,mutations,actions
}

4.src/store/index 代码如下：

import Vue from 'vue'
import Vuex from 'vuex'
import getters from './getters'
import app from './modules/app'
import settings from './modules/settings'
import user from './modules/user'
// 权限设置
import permission from './modules/permission'Vue.use(Vuex)const store = new Vuex.Store({modules: {app,settings,user,permission // 权限设置},getters
})export default store

5.src/permission.js 代码如下：

// 引入路由器router
import router from './router'
// 引入仓库
import store from './store'
// 引入ele的提示组件
import { Message } from 'element-ui'
// 引入交互进度条
import NProgress from 'nprogress' // progress bar
import 'nprogress/nprogress.css' // progress bar style
// 从cookie中获取token，登录了就有cookie
import { getToken } from '@/utils/auth' // get token from cookie
// 得到页面的title
import getPageTitle from '@/utils/get-page-title'// 配置nprogress
NProgress.configure({ showSpinner: false }) // NProgress Configuration// 白名单，不需要登录就能进入的路由
const whiteList = ['/login'] // no redirect whitelist// 全局前置路由守卫
router.beforeEach(async(to, from, next) => {//开启进度条NProgress.start()//给页面的title赋值document.title = getPageTitle(to.meta.title)// 从cookie中拿到token，有的话就放行，determine whether the user has logged inconst hasToken = getToken()if (hasToken) {if (to.path === '/login') {// if is logged in, redirect to the home pagenext({ path: '/' })NProgress.done()} else {// 获取用户信息// const hasGetUserInfo = store.getters.nameconst hasRoles = store.getters.roles && store.getters.roles.length > 0// 权限控制console.log('roles:',store.getters.roles)// if (hasGetUserInfo) {if (hasRoles) {console.log('执行了1')next()} else {console.log('执行了2')try {// get user info 重新获取用户信息// await store.dispatch('user/getInfo')// 权限控制const { roles } = await store.dispatch('user/getInfo')// 在角色权限基础上生成动态路由表const accessRoutes = await store.dispatch('permission/generateRoutes', roles)console.log('accessRoutes:',accessRoutes)router.options.routes = store.getters.permission_routes // 动态添加可访问路由router.addRoutes(accessRoutes)console.log('输出的store：',store)next({...to, replace: true })// next()} catch (error) {// remove token and go to login page to re-loginawait store.dispatch('user/resetToken')Message.error(error || 'Has Error')next(`/login?redirect=${to.path}`)NProgress.done()}}}} else {/* has no token*/if (whiteList.indexOf(to.path) !== -1) {// in the free login whitelist, go directlynext()} else {// other pages that do not have permission to access are redirected to the login page.next(`/login?redirect=${to.path}`)// 关闭进度条NProgress.done()}}
})// 全局后置路由守卫
router.afterEach(() => {// finish progress barNProgress.done()
})

6.src/store/getters.js：

const getters = {sidebar: state => state.app.sidebar,device: state => state.app.device,token: state => state.user.token,avatar: state => state.user.avatar,name: state => state.user.name,// 权限设置roles: state => state.user.roles,permission_routes: state => state.permission.routes
}
export default getters

经过上面的配置，应该就可以完成权限管理了。如果有问题的话留言评论
