//先导入这些乱七八糟的
import Vue from 'vue'import Router from 'vue-router'import store from '@/store/index'import NProgress from 'nprogress'import 'nprogress/nprogress.css'import gatewayHomeRouter from './gatewayHome'Vue.use(Router)//不需要权限的路由export const constantRoutes = [
{
path: '/',
redirect: '/entrance'
},
{
path: '/entrance',
component: () => import('@/views/Index.vue'),
meta: { isEntrance: true }
},
{
path: '/register',
name: 'register',
component: () => import('@/views/common/Register.vue')
},
{
path: '/login',
name: 'login',
component: () => import('@/views/common/Login.vue')
},
{
path: '/logout',
name: 'logout',
component: () => import('@/views/common/Logout.vue')
},
{
path: '/quit',
name: 'quit',
component: () => import('@/views/common/Quit.vue')
},
{
path: '/error/:id',
name: '404',
component: () => import('@/views/common/404.vue')
},
{
path: '/Admittance',
name: 'Admittance',
component: () => import('@/views/common/Admittance.vue')
}, // gatewayHomeRouter]
export const asyncRoutes = gatewayHomeRouter
const createRouter = () => new Router({
mode: 'history',
base: process.env.BASE_URL,
routes: constantRoutes
})
const router: any = createRouter()//写一个重置路由的方法，切换用户后，或者退出时清除动态加载的路由export function resetRouter() {
const newRouter: any = createRouter()
router.matcher = newRouter.matcher // 新路由实例matcer，赋值给旧路由实例的matcher，（相当于replaceRouter）}//不需要权限的白名单pathconst whiteList = ['/entrance', '/register', '/login', '/logout', '/error', '/Admittance', '/quit']
router.beforeEach(async (to, from, next) => {
NProgress.start() //登录后的用户有token
const hasToken = sessionStorage.getItem('Authorization')
//注销后的用户的识别
let isEffect = store.state.isEffect if (isEffect === '0') {if (to.path !== '/quit') {
next('/quit')
}
} if (hasToken) {if (to.path === '/login') { // 已登录的用户，想去登录页就重定向到首页 next({ path: '/' })
NProgress.done()
} else { if (store.state.isMountedRoutes) {if (to.path === '/entrance') {
next('/home')
}
next()
} else {try {
//登录后获取用户角色 const { roleTypeDetail } = await store.dispatch('COMMIT_USER_LOGIN')
let roles: any = [Number(roleTypeDetail)]
//根据角色遍历出来对应可以显示的路由 const acce***outes = await store.dispatch('permission/generateRoutes', roles)
//通过addRoutes加载路由 router.addRoutes(acce***outes)
//存储已加载的状态，下次就不会进入这个try store.commit('SET_IS_MOUNTED_ROUTES', true)
NProgress.done() next({ path: to.path })
} catch (error) { // 清除token重新跳转登录页 // await store.dispatch('user/resetToken') store.dispatch('COMMIT_LOGOUT')
next(`/login`) NProgress.done()
}
}
}
} else {//白名单直接里边请if (whiteList.indexOf(to.path) !== -1) {
next()
} else { // 其他无权限的重定向到登录页 next(`/login`) NProgress.done()
}
}
})
router.afterEach(() => {
NProgress.done()
})
export default router下面是permission.ts文件，这个文件只做了一件事，就是根据路由meta对象的某个属性值，来过滤出来对应值拥有的路由对象，以供addRoutes，直接拿过去用
import { asyncRoutes, constantRoutes } from '@/router'//判断是否有权限function hasPermission(roles, route) {
if (route.meta && route.meta.identity) {
return roles.some(role => route.meta.identity.includes(role))
} else {
return true
}
}//过滤出有权限的路由export function filterAsyncRoutes(routes, roles) {
const res: any = []
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 permission = {
namespaced: true,
state: {
routes: [],
addRoutes: []
},
mutations: {
SET_ROUTES: (state, routes) => {
state.addRoutes = routes
//把之前的路由和后过滤出来的路由拼接起来一个新数组state.routes = constantRoutes.concat(routes)
}
},
actions: {
//构建路由的函数async generateRoutes({ commit }, roles) {
return new Promise(resolve => {
let accessedRoutes
if (roles.includes(5)) {
accessedRoutes = asyncRoutes || []
} else {
accessedRoutes = filterAsyncRoutes(asyncRoutes, roles)
}
commit('SET_ROUTES', accessedRoutes)
resolve(accessedRoutes)
})
}
},
getters: {},
}
//导出供使用export default permission下面是那个倒霉的要被过滤来过滤去的路由数组
const gatewayHomeRouter = [{
path: '/home',
component: () => import('@/views/home/Index.vue'),
children: [
{
path: '',
redirect: 'gateway'
},
{
path: 'gateway',
name: 'gateway',
meta: {
title: '首页',
icon: 'el-icon-rank',
identity: [1, 2, 3, 4, 5]//这就是几种角色 },
component: () => import('@/views/home/gateway/Index.vue')
},
{
path: 'supplierMaintenance',
name: 'supplierMaintenance',
meta: {
title: '供应商基本信息维护',
icon: 'el-icon-rank',
identity: [2, 3, 4, 5]
},
component: () => import('@/views/home/supplierMaintenance/Index.vue')
},
{
path: 'personnelManagement',
name: 'personnelManagement',
meta: {
title: '供应商人员管理',
icon: 'el-icon-rank',
identity: [5]
},
component: () => import('@/views/home/personnelManagement/Index.vue')
},
{
path: 'userInfo',
name: 'userInfo',
meta: {
title: '个人信息',
icon: 'el-icon-rank',
identity: [2, 3, 4, 5]
},
component: () => import('@/views/home/userInfo/Index.vue')
},
]
}]
export default gatewayHomeRouter项目菜单栏也可以遍历新路由数组生成。。。
好了，抄完了
