改造router/index.js

import  from 'vue'
import Router from 'vue-router'

Vue.use(Router)

/* Layout */
import Layout from '@/layout'

// 基礎路由
export const constantRoutes = [
  {
    path: '/login',component: () => import('@/views/login/index'),hidden: true
  },{
    path: '/404',component: () => import('@/views/404'),{
    path: '/',component: Layout,redirect: '/dashboard',children: [{
      path: 'dashboard',name: 'Dashboard',component: () => import('@/views/dashboard/index'),meta: { title: '首頁',icon: 'el-icon-menu' }
    }]
  },]

/**
 * 動態路由
 */
export const asyncRoutes = [
  {
    path: '/studentinformation',children: [
      {
        path: 'index',component: () => import('@/views/studentinformation/index'),meta: { title: '學生資訊',icon: 'el-icon-s-check' }
      }
    ]
  },{
    path: '/lecturerinformation',component: () => import('@/views/lecturerinformation/index'),meta: { title: '講師資訊',icon: 'el-icon-s-custom',roles: ['editor'] }
      }
    ]
  },{
    path: '/coursemanage',meta: { roles: ['admin'] },component: () => import('@/views/coursemanage/index'),meta: { title: '課程管理',icon: 'el-icon-s-platform'}
      }
    ]
  },// 404 頁面必須放置在最後一個頁面
  { 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://.com/vuejs/vue-router/issues/1234#issuecomment-357941465
export function resetRouter() {
  const newRouter = createRouter()
  router.matcher = newRouter.matcher // reset router
}

export default router

將動態顯示的路由寫在asyncRoutes 中並新增 roles ，例如meta: { roles: [‘admin'] },

在store/modulds目錄下新增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: '',yTwDZroles: []
  }
}

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('驗證失敗，請重新登入')
        }

        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,reject) => {
      logout(state.token).then(() => {
        removeToken() // must remove  token  first
        resetRouter()
        commit('RESET_STATE')
        commit('SET_ROLES',[])
        resolve()
      }).catch(error => {
        reject(error)
      })
    })
  },// remove tokwww.cppcns.comen
  resetToken({ commit }) {
    return new Promise(resolve => {
      removeToken() // must remove  token  first
      commit('RESET_STATE')
      commit('SET_ROLES',[])
      resolve()
    })
  }
}

export default {
  namespaced: true,actions
}

新增roles: [] 儲存許可權列表 ，新增內容如下

const getDefaultState = () => {
  return {
    ...
    roles: []
  }
}

const mutations = {
  ...
  SET_ROLES: (state,roles) => {
    state.roles = roles
  }
}

  // get user info
  getInfo({ commit,reject) => {
      getInfo(state.token).then(response => {
        ...
        const {roles,roles)
        ...
      }).catch(error => {
        reject(error)
      })
    })
  },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中新增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,//新增roles
  roles: state => state.user.roles,//動態路由
  permission_routes: state => state.permission.routes,}
export default getters

將permission新增到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'

//新增permission
import permission from './modules/permission'

Vue.use(Vuex)

const store = new Vuex.Store({
  modules: {
    app,settings,user,//新增permission
    permission
  },getters
})

export default store

最後修改根目錄下的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.' // 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()
www.cppcns.com
  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()
})

將資料繫結到nav導航欄上

在layout/components/sidebar/index.vue中

...mapGetters([
      // 動態路由 增加permission_routes
      'permission_routes','sidebar'
    ]),<!-- 動態路由 -->
 <sidebar-item v-for="route in permission_routes" :key="route.path" :item="route" :base-path="route.path" />

全部程式碼如下：

<template>
  <div :class="{ 'has-logo': showLogo }">
    <logo v-if="showLogo" :collapse="isCollapse" />
    <el-scrollbar wrap-class="scrollbar-wrapper">
      <el-menu
        :default-active="activeMenu"
        :collapse="isCollapse"

        :active-text-color="variables.menuActiveText"
        :collapse-transition="false"
        mode="vertical"
      >
        <!-- <sidebar-item
          v-for="route in routes"
          :key="route.path"
          :item="route"

        /> -->
        <sidebar-item
          v-for="route in permission_routes"
          :key="route.path"
          :item="route"

        />
      </el-menu>
