提供登录与获取用户信息数据接口
在api/user.js中
import request from '@/utils/request'
const Api = {
TakeOut: '/student/students/takeOut/',
LoginIn: '/student/students/loginIn/',
StudentInfo:'/student/students/studentInfo/',
}
export function login(parameter) {
return request({
url: Api.LoginIn,
method: 'get',
params: parameter
})
}
export function getInfo(token) {
return request({
url: Api.StudentInfo,
method: 'get',
params: {'token':token}
})
}
export function logout() {
return request({
url: Api.TakeOut,
method: 'get'
})
}
登录接口数据
{'code': 200, 'data': {'token': 'X-admin'}, 'message': "操作成功"}
退出接口数据

改造router/index.js
import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
/* Layout */
import Layout from '@/layout'
// 基础路由
export const constantRoutes = [
{
path: '/login',
component: () => import('@/views/login/index'),
hidden: true
},
{
path: '/404',
component: () => import('@/views/404'),
hidden: true
},
{
path: '/',
component: Layout,
redirect: '/dashboard',
children: [{
path: 'dashboard',
name: 'Dashboard',
component: () => import('@/views/dashboard/index'),
meta: { title: '首页', icon: 'el-icon-menu' }
}]
},
]
/**
* 动态路由
*/
export const asyncRoutes = [
{
path: '/studentinformation',
component: Layout,
children: [
{
path: 'index',
component: () => import('@/views/studentinformation/index'),
meta: { title: '学生信息', icon: 'el-icon-s-check' }
}
]
},
{
path: '/lecturerinformation',
component: Layout,
children: [
{
path: 'index',
component: () => import('@/views/lecturerinformation/index'),
meta: { title: '讲师信息', icon: 'el-icon-s-custom', roles: ['editor'] }
}
]
},
{
path: '/coursemanage',
component: Layout,
meta: { roles: ['admin'] },
children: [
{
path: 'index',
component: () => import('@/views/coursemanage/index'),
meta: { title: '课程管理', icon: 'el-icon-s-platform'}
}
]
},
// 404 页面必须放置在最后一个页面
{ path: '*', redirect: '/404', hidden: true }
]
const createRouter = () => new Router({
// mode: 'history', // require service support
scrollBehavior: () => ({ 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
将动态显示的路由写在asyncRoutes 中并添加 roles ，例如meta: { roles: [‘admin'] },
在store/modulds目录下添加permission.js
import { asyncRoutes, constantRoutes } from '@/router'
/**
* Use meta.role to determine if the current user has permission
* @param roles
* @param route
*/
function hasPermission(roles, route) {
if (route.meta && route.meta.roles) {
return roles.some(role => route.meta.roles.includes(role))
} else {
return true
}
}
/**
* Filter asynchronous routing tables by recursion
* @param routes asyncRoutes
* @param roles
*/
export function filterAsyncRoutes(routes, roles) {
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 = routes
state.routes = constantRoutes.concat(routes)
}
}
const actions = {
generateRoutes({ commit }, roles) {
return new Promise(resolve => {
const accessedRoutes = filterAsyncRoutes(asyncRoutes, roles)
commit('SET_ROUTES', accessedRoutes)
resolve(accessedRoutes)
})
}
}
export default {
namespaced: true,
state,
mutations,
actions
}
修改store/modulds/user.js
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: []
}
}
const state = getDefaultState()
const mutations = {
RESET_STATE: (state) => {
Object.assign(state, getDefaultState())
},
SET_TOKEN: (state, token) => {
state.token = token
},
SET_NAME: (state, name) => {
state.name = name
},
SET_AVATAR: (state, avatar) => {
state.avatar = avatar
},
SET_ROLES: (state, roles) => {
state.roles = roles
}
}
const actions = {
// user login
login({ commit }, userInfo) {
const { username, password } = userInfo
return new Promise((resolve, reject) => {
login({ username: username.trim(), password: password }).then(response => {
const { data } = response
commit('SET_TOKEN', data.token)
setToken(data.token)
resolve()
}).catch(error => {
reject(error)
})
})
},
// get user info
getInfo({ commit, state }) {
return new Promise((resolve, reject) => {
getInfo(state.token).then(response => {
const { data } = response
if (!data) {
return reject('验证失败，请重新登录')
}
const {roles, name, avatar } = data
commit('SET_ROLES', roles)
commit('SET_NAME', name)
commit('SET_AVATAR', avatar)
resolve(data)
}).catch(error => {
reject(error)
})
})
},
// user logout
logout({ commit, state }) {
return new Promise((resolve, reject) => {
logout(state.token).then(() => {
removeToken() // must remove token first
resetRouter()
commit('RESET_STATE')
commit('SET_ROLES', [])
resolve()
}).catch(error => {
reject(error)
})
})
},
// remove token
resetToken({ commit }) {
return new Promise(resolve => {
removeToken() // must remove token first
commit('RESET_STATE')
commit('SET_ROLES', [])
resolve()
})
}
}
export default {
namespaced: true,
state,
mutations,
actions
}
添加roles: [] 保存权限列表 ，添加内容如下
const getDefaultState = () => {
return {
...
roles: []
}
}
const mutations = {
...
SET_ROLES: (state, roles) => {
state.roles = roles
}
}
// get user info
getInfo({ commit, state }) {
return new Promise((resolve, reject) => {
getInfo(state.token).then(response => {
...
const {roles, name, avatar } = data
commit('SET_ROLES', roles)
...
}).catch(error => {
reject(error)
})
})
},
// user logout
logout({ commit, state }) {
return new Promise((resolve, reject) => {
logout(state.token).then(() => {
...
commit('SET_ROLES', [])
...
}).catch(error => {
reject(error)
})
})
},
// remove token
resetToken({ commit }) {
return new Promise(resolve => {
...
commit('SET_ROLES', [])
...
})
}
}
在store/getters.js中添加roles
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,
//添加roles
roles: state => state.user.roles,
//动态路由
permission_routes: state => state.permission.routes,
}
export default getters
将permission添加到store/index.js中
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'
//添加permission
import permission from './modules/permission'
Vue.use(Vuex)
const store = new Vuex.Store({
modules: {
app,
settings,
user,
//添加permission
permission
},
getters
})
export default store
最后修改根目录下的permission.js
import router, { constantRoutes } from './router'
import store from './store'
import { Message } from 'element-ui'
import NProgress from 'nprogress' // progress bar
import 'nprogress/nprogress.css' // progress bar style
import { getToken } from '@/utils/auth' // get token from cookie
import getPageTitle from '@/utils/get-page-title'
NProgress.configure({ showSpinner: false }) // NProgress Configuration
const whiteList = ['/login'] // no redirect whitelist
router.beforeEach(async (to, from, next) => {
// start progress bar
NProgress.start()
// set page title
document.title = getPageTitle(to.meta.title)
// determine whether the user has logged in
const hasToken = getToken()
if (hasToken) {
if (to.path === '/login') {
// if is logged in, redirect to the home page
next({ path: '/' })
NProgress.done()
} else {
const hasRoles = store.getters.roles && store.getters.roles.length > 0
if (hasRoles) {
next()
} else {
try {
// get user info
// note: roles must be a object array! such as: ['admin'] or ,['developer','editor']
const { roles } = await store.dispatch('user/getInfo')
console.log(roles)
// generate accessible routes map based on roles
const accessRoutes = await store.dispatch('permission/generateRoutes', roles)
// dynamically add accessible routes
router.options.routes = constantRoutes.concat(accessRoutes)
router.addRoutes(accessRoutes)
// hack method to ensure that addRoutes is complete
// set the replace: true, so the navigation will not leave a history record
next({ ...to, replace: true })
} catch (error) {
// remove token and go to login page to re-login
await store.dispatch('user/resetToken')
Message.error(error || 'Has Error')
next(`/login?redirect=${to.path}`)
NProgress.done()
}
}
}
} else {
/* has no token*/
if (whiteList.indexOf(to.path) !== -1) {
// in the free login whitelist, go directly
next()
} else {
// other pages that do not have permission to access are redirected to the login page.
next(`/login?redirect=${to.path}`)
NProgress.done()
}
}
})
router.afterEach(() => {
// finish progress bar
NProgress.done()
})
将数据绑定到nav导航栏上
在layout/components/sidebar/index.vue中
...mapGetters([
// 动态路由 增加permission_routes
'permission_routes',
'sidebar'
]),
全部代码如下：
