vue+vue-router+vuex operation permissions
This time I will bring you the vue vue-router vuex operation permissions. What are the precautions for vue vue-router vuex operation permissions? Here are the actual cases, let’s take a look.
https://github.com/linrunzheng/vue- permission-control
Next, let us simulate the process of an ordinary user opening the website and walk through the entire process step by step. First start by opening the local service localhost:8080. We know that after opening, we will enter the login page, so what is the basis for judgment. First is the token. Users who are not logged in will not be able to obtain the token. For characters after logging in, we will save the token to local or seesionStorage. Therefore, you can know whether to log in or not based on whether there is a token currently.In order to access the token and facilitate our operation, it can be combined with vuex to achieve
/* state.js */ export default { get UserToken() { return localStorage.getItem('token') }, set UserToken(value) { localStorage.setItem('token', value) } } /* mutation.js */ export default { LOGIN_IN(state, token) { state.UserToken = token }, LOGIN_OUT(state) { state.UserToken = '' } }
Interception judgment
No token Enter the page that requires permissions: redirect to the login pageSince our routes are dynamically mounted, including ' ' and 404, when no route is matched, we will also redirect to loginrouter.beforeEach((to, from, next) => { if (!store.state.UserToken) { if ( to.matched.length > 0 && !to.matched.some(record => record.meta.requiresAuth) ) { next() } else { next({ path: '/login' }) } } })
/* 初始路由 */ export default new Router({ routes: [ { path: '/login', component: Login } ] }) /* 准备动态添加的路由 */ export const DynamicRoutes = [ { path: '', component: Layout, name: 'container', redirect: 'home', meta: { requiresAuth: true, name: '首页' }, children: [ { path: 'home', component: Home, name: 'home', meta: { name: '首页' } } ] }, { path: '/403', component: Forbidden }, { path: '*', component: NotFound } ]
router.beforeEach((to, from, next) => { if (!store.state.UserToken) { ... } else { /* 现在有token了 */ if (!store.state.permission.permissionList) { /* 如果没有permissionList,真正的工作开始了 */ store.dispatch('permission/FETCH_PERMISSION').then(() => { next({ path: to.path }) }) } else { if (to.path !== '/login') { next() } else { next(from.fullPath) } } } })
actions: { async FETCH_PERMISSION({ commit, state }) { /* 获取后台给的权限数组 */ let permissionList = await fetchPermission() /* 根据后台权限跟我们定义好的权限对比,筛选出对应的路由并加入到path=''的children */ let routes = recursionRouter(permissionList, dynamicRouter) let MainContainer = DynamicRoutes.find(v => v.path === '') let children = MainContainer.children children.push(...routes) /* 生成左侧导航菜单 */ commit('SET_MENU', children) setDefaultRoute([MainContainer]) /* 初始路由 */ let initialRoutes = router.options.routes /* 动态添加路由 */ router.addRoutes(DynamicRoutes) /* 完整的路由表 */ commit('SET_PERMISSION', [...initialRoutes, ...DynamicRoutes]) } }
{ "code": 0, "message": "获取权限成功", "data": [ { "name": "订单管理", "children": [ { "name": "订单列表" }, { "name": "生产管理", "children": [ { "name": "生产列表" } ] }, { "name": "退货管理" } ] } ] }
/* 这里是我们写好的需要权限判断的路由 */ const dynamicRoutes = [ { path: '/order', component: Order, name: 'order-manage', meta: { name: '订单管理' }, children: [ { path: 'list', name: 'order-list', component: OrderList, meta: { name: '订单列表' } }, { path: 'product', name: 'product-manage', component: ProductManage, meta: { name: '生产管理' }, children: [ { path: 'list', name: 'product-list', component: ProductionList, meta: { name: '生产列表' } }, { path: 'review', name: 'review-manage', component: ReviewManage, meta: { name: '审核管理' } } ] }, { path: 'returnGoods', name: 'return-goods', component: ReturnGoods, meta: { name: '退货管理' } } ] } ] export default dynamicRoutes
recursive function, using name and meta .name for comparison, we can get the result we want based on this function
/** * * @param {Array} userRouter 后台返回的用户权限json * @param {Array} allRouter 前端配置好的所有动态路由的集合 * @return {Array} realRoutes 过滤后的路由 */ export function recursionRouter(userRouter = [], allRouter = []) { var realRoutes = [] allRouter.forEach((v, i) => { userRouter.forEach((item, index) => { if (item.name === v.meta.name) { if (item.children && item.children.length > 0) { v.children = recursionRouter(item.children, v.children) } realRoutes.push(v) } }) }) return realRoutes }
{ path: '', component: Layout, name: 'container', redirect: 'home', meta: { requiresAuth: true, name: '首页' }, children: [ { path: 'home', component: Home, name: 'home', meta: { name: '首页' } }, <!-- 将上面得到的东西加入到这里 --> ... ] }
/* 动态添加路由 */ router.addRoutes(DynamicRoutes) /* 初始路由 */ let initialRoutes = router.options.routes /* 合并起来,就是完整的路由了 */ commit('SET_PERMISSION', [...initialRoutes, ...DynamicRoutes])
<template> <p class="menu-container"> <template v-for="v in menuList"> <el-submenu :index="v.name" v-if="v.children&&v.children.length>0" :key="v.name"> <template slot="title"> <i class="iconfont icon-home"></i> <span>{{v.meta.name}}</span> </template> <el-menu-item-group> <my-nav :menuList="v.children"></my-nav> </el-menu-item-group> </el-submenu> <el-menu-item :key="v.name" :index="v.name" @click="gotoRoute(v.name)" v-else> <i class="iconfont icon-home"></i> <span slot="title">{{v.meta.name}}</span> </el-menu-item> </template> </p> </template> <script> export default { name: 'my-nav', props: { menuList: { type: Array, default: function() { return [] } } }, methods: { gotoRoute(name) { this.$router.push({ name }) } } } </script>
breadcrumb navigation can be achieved by obtaining all matched routes in the afterEach stage.
if (!store.state.permission.permissionList) { store.dispatch('permission/FETCH_PERMISSION').then(() => { next({ path: to.path }) }) } ... router.afterEach((to, from, next) => { var routerList = to.matched store.commit('setCrumbList', routerList) store.commit('permission/SET_CURRENT_MENU', to.name) })
退出登陆后,需要刷新页面,因为我们是通过addRoutes添加的,router没有deleteRoutes这个api,所以清除token,清除permissionList等信息,刷新页面是最保险的。
最后还有一点,每次请求得带上token, 可以对axios封装一下来处理
var instance = axios.create({ timeout: 30000, baseURL }) // 添加请求拦截器 instance.interceptors.request.use( function(config) { // 请求头添加token if (store.state.UserToken) { config.headers.Authorization = store.state.UserToken } return config }, function(error) { return Promise.reject(error) } ) /* axios请求二次封装 */ instance.get = function(url, data, options) { return new Promise((resolve, reject) => { axios .get(url, data, options) .then( res => { var response = res.data if (response.code === 0) { resolve(response.data) } else { Message.warning(response.message) /* reject(response.message) */ } }, error => { if (error.response.status === 401) { Message.warning({ message: '登陆超时,请重新登录' }) store.commit('LOGIN_OUT') window.location.reload() } else { Message.error({ message: '系统异常' }) } reject(error) } ) .catch(e => { console.log(e) }) }) } export default instance

sudo (superuser execution) is a key command in Linux and Unix systems that allows ordinary users to run specific commands with root privileges. The function of sudo is mainly reflected in the following aspects: Providing permission control: sudo achieves strict control over system resources and sensitive operations by authorizing users to temporarily obtain superuser permissions. Ordinary users can only obtain temporary privileges through sudo when needed, and do not need to log in as superuser all the time. Improved security: By using sudo, you can avoid using the root account during routine operations. Using the root account for all operations may lead to unexpected system damage, as any mistaken or careless operation will have full permissions. and
