作业 （ 基于权限接口和线上效果完成 权限点的新增- 删除- 编辑 ）
本次作业我封装了一个添加组件
子组件：

<el-form-item label="权限标识" prop="code">
<el-input v-model="formData.code" style="width: 80%" size="mini" />
</el-form-item>
<el-form-item label="权限描述" prop="description">
<el-input
v-model="formData.description"
style="width: 80%"

<!-- 如果不需要校验，就不需要写prop属性 -->
<!-- 重置表单数据，需要prop属性 -->

// 静态路由
export const constantRoutes = [

},

path: '/404',
component: () => import('@/views/404'),

children: [
{
path: 'dashboard',
name: 'Dashboard',
component: () => import('@/views/dashboard/index'),
meta: { title: '首页', icon: 'dashboard' }
}
]
},
// 404 page must be placed at the end !!!
{ path: '*', redirect: '/404', hidden: true }
]
// 动态路由
export const asyncRoutes = [
department,
role,
employee,
permission,
attendance,
approval,
salary,
social
]
const createRouter = () =>
new Router({
// mode: 'history', // require service support
scrollBehavior: () => ({ y: 0 }),
routes: constantRoutes // 默认引入静态路由
})根据用户权限添加动态路由
permission完整代码
router.beforeEach(async (to, from, next) => {
nprogress.start() // 开启进度条
// 判断是否有token
if (store.getters.token) {
// 如果有token,则判断是否是登录页
if (to.path === '/login') {
// 如果是则跳转到主页
next('/')
// next有地址的话并没有执行后置守卫,所以要手动调用一下进度条关闭

// 判断是否获取过资料
if (!store.getters.userId) {
// 如果没有则获取资料
const { roles } = await store.dispatch('user/getUserInfo')
const filterRoutes = asyncRoutes.filter(item => {
return roles.menus.includes(item.name)
}) // 筛选后的路由
router.addRoutes([
...filterRoutes,
{ path: '*', redirect: '/404', hidden: true }
]) // 添加动态路由信息到路由表
// router添加动态路由之后 需要转发一下
next(to.path) // 目的是让路由拥有信息 router的已知缺陷
} else {
next() // 放过
}
}
} else {
// 判断是否在白名单里面
if (whiteList.includes(to.path)) {

// 动态路由
export const asyncRoutes = [

employee,
permission,

approval,
salary,
social
]
const createRouter = () =>
new Router({
// mode: 'history', // require service support

routes: constantRoutes // 默认引入静态路由
})// 获取用户的基本资料
async getUserInfo (context) {
const result = await getUserInfo()
context.commit('setUserInfo', result)
return result // 返回数据
}这里以approval路由为例，其他路由都要添加name属性
import layout from '@/layout'
export default {

name: 'approval',
component: layout,
children: [
{
path: '',
name: 'approval',
component: () => import('@/views/approval'),

}
}
]
}根据权限显示左侧菜单
import { constantRoutes } from '@/router'
// 存放数据
const state = {
routes: constantRoutes // 存储路由信息，默认存储的是静态路由
}
// 修改数据
const mutations = {
setRoutes (state, newRoutes) {
state.routes = [...constantRoutes, ...newRoutes] // 静态路由+动态路由
}
}const getters = {
routes: state => state.user.routes
}
// getters编辑访问
export default getters
const { roles } = await store.dispatch('user/getUserInfo')
const filterRoutes = asyncRoutes.filter(item => {
return roles.menus.includes(item.name)
}) // 筛选后的路由
store.commit('user/setRoutes', filterRoutes)
router.addRoutes([

{ path: '*', redirect: '/404', hidden: true }
]) // 添加动态路由信息到路由表computed: {
...mapGetters(['sidebar', 'routes']),
// 路由信息的计算属性
// routes () {
// // 当前路由的所有信息
// return this.$router.options.routes
// },
}退出登录重置路由
import { resetRouter } from '@/router'
// 异步操作
const actions = {
// 退出登录
logout (context) {
// 1.删除token
context.commit('removeToken')
// 2.删除用户信息
context.commit('setUserInfo', {})
// 重置路由
resetRouter()
}
}功能权限-按钮权限标识
自定义指令应用功能权限
代码层面：
// 注册自定义指令，控制功能权限
Vue.directive('permission', {
// 会在指令作用的元素插入dom之后执行
inserted (el, binding) {
// el是当前指令作用的dom元素的对象
// binding是v-permission="表达式"的信息
const points = store.state.user.userInfo?.roles?.points || []
// 判断当前登录用户（数组）是否包含权限点，不存在就要将对应的按钮删除或禁用
if (!points.includes(binding.value)) {
// 删除
el.remove()
// 禁用
// el.disabled = true
}
}
})<el-button
v-permission="add - employee"
size="mini"
type="primary"
@click="$router.push('/employee/detail')"
>添加员工</el-button
>页面层面（标识要和代码一致）：
