end authority control implementation dynamic


In the development of application system in the background , In most cases, it will involve the control of user rights , In addition to the back-end permission verification , The front end also needs to make corresponding control based on the user's permission when accessing . For front end use vue Frame situation , Access control at the page level , The normal processing is to control the permissions explicitly and implicitly by controlling the navigation bar in the page navigation bar , But you can still access it by entering the access path in the browser address bar , It can be used vue-router The dynamic path of access control is realized .

// router.js
import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
// The default route only configures pages that do not require permissions
export default new Router({
mode: 'history',
base: process.env.BASE_URL,
routes: [
{
path: '/',
redirect: '/user/login'
},
{
path: '/user/login',
name: 'login',
component: () => import('@/views/user/Login.vue')
}
]
})

Log in successfully and pass addRoutes Update routing configuration

import routeConfig from '@/routeConfig'
this.$api.user.login({
username,
password
}).then(res => {
if(res.data.code === 0) {
// Login successful , Configure dynamic routing according to the return permission code
let router = routeConfig();
router.routes.forEach(route => this.$router.options.routes.push(route));
// Must route push To options It will come into effect only in the middle of the year
this.$router.addRoutes(router.routes);
}
})

Under normal circumstances, this can achieve dynamic routing control , But refresh the page and find that 404, Because when refreshing vue Instance reinitialized , Causes the dynamic route to be restored to the default route , In this case, you need to store the permission code locally , stay main.js According to the permission code, the dynamic route is generated again

// When the page is refreshed, the route is regenerated according to the local cache
if(sessionStorage.getItem('permission')) {
let routerData = routeConfig();
routerData.routes.forEach(route => router.options.routes.push(route));
router.addRoutes(routerData.routes);
}

The above steps can basically add routes dynamically and maintain the routing status in the refresh page , Always go to the root page, but jump to the root path , Cannot default to jump to the home page , There is no good solution to this problem .
