人力资源智能化管理项目(day09:权限应用)

学习源码可以看我的个人前端学习笔记 (github.com):qdxzw/humanResourceIntelligentManagementProject

搭建页面结构

<template>
  <div class="container">
    <div class="app-container">
      <el-button class="btn-add" type="primary" size="mini">添加权限</el-button>
      <el-table>
        <el-table-column label="名称" />
        <el-table-column label="标识" />
        <el-table-column label="描述" />
        <el-table-column label="操作">
          <el-button type="text">添加</el-button>
          <el-button type="text">编辑</el-button>
          <el-button type="text">删除</el-button>
        </el-table-column>
      </el-table>
    </div>
  </div>
</template>
<script>
export default {
  name: 'Permission'
}
</script>
<style>
.btn-add {
  margin: 10px;
}
</style>

获取数据转化树形

import request from '@/utils/request'

/**
 *
 * 获取权限列表
 *
 */
export function getPermissionList () {
  return request({
    url: '/sys/permission',
    method: 'GET'
  })
}

  <template>
  <div class="container">
    <div class="app-container">
      <el-button class="btn-add" type="primary" size="mini">添加权限</el-button>
      <el-table default-expand-all :data="list" row-key="id">
        <el-table-column prop="name" label="名称" />
        <el-table-column prop="code" label="标识" />
        <el-table-column prop="description" label="描述" />
        <el-table-column label="操作">
          <template v-slot="{ row }">
            <el-button v-if="row.type === 1" size="mini" type="text"
              >添加</el-button
            >
            <el-button type="text" size="mini">编辑</el-button>
            <el-button type="text" size="mini">删除</el-button>
          </template>
        </el-table-column>
      </el-table>
    </div>
  </div>
</template>
<script>
import { getPermissionList } from '@/api/permission'
import { transListToTreeData } from '@/utils/index'
export default {
  name: 'Permission',
  data () {
    return {
      list: []
    }
  },
  created () {
    this.getPermissionList()
  },
  methods: {
    async getPermissionList () {
      this.list = transListToTreeData(await getPermissionList(), 0)
      console.log(this.list)
    }
  }
}
</script>
<style>
.btn-add {
  margin: 10px;
}
</style>

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:

<template>
  <el-dialog :title="showTitle" :visible="showDialog" @close="close">
    <!-- 放置弹层内容 -->
    <el-form ref="addDept" label-width="120px" :model="formData" :rules="rules">
      <el-form-item label="权限名称" prop="name">
        <el-input v-model="formData.name" style="width: 80%" size="mini" />
      </el-form-item>
      <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%"
          size="mini"
        />
      </el-form-item>
      <!-- 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 -->
      <el-form-item label="启用" prop="enVisible">
        <el-switch
          v-model="formData.enVisible"
          :active-value="1"
          :inactive-value="0"

权限概念

分配过程

员工分配角色-弹出层

给角色分配权限-弹出层

      showPermissionDialog: false, // 控制权限弹层的显隐
      permissionData: [] // 接收权限树数据

<el-button size="mini" type="text" @click="btnPermission"

角色分配权限-显示已有权限数据

/**

 */
export function getRoleDetail (id) {
  return request({
    url: `/sys/role/${id}`,
    method: 'GET'

        show-checkbox
        default-expand-all
        :default-checked-keys="permIds"

角色分配权限-确定提交

/**

 */
export function assignPrem (data) {

拆分静态路由和动态路由

// 静态路由
export const constantRoutes = [
  {
    path: '/login',
    component: () => import('@/views/login/index'),
    hidden: true
  },

  {
    path: '/404',
    component: () => import('@/views/404'),
    hidden: true
  },

  {
    path: '/',
    component: Layout,
    redirect: '/dashboard',
    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
      nprogress.done()
    } else {
      // 如果不是则放过
      // 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)) {
      // 如果在就放过
      next()
    } else {
      // 如果不在,就跳转到登录
      next('/login')
      nprogress.done()
    }
  }
})

// 静态路由
export const constantRoutes = [
  {
    path: '/login',
    component: () => import('@/views/login/index'),
    hidden: true
  },

  {
    path: '/404',
    component: () => import('@/views/404'),
    hidden: true
  },

  {
    path: '/',
    component: Layout,
    redirect: '/dashboard',
    children: [
      {
        path: 'dashboard',
        name: 'Dashboard',
        component: () => import('@/views/dashboard/index'),
        meta: { title: '首页', icon: 'dashboard' }
      }
    ]
  }
  // 404 page must be placed at the end !!!
]
// 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
  })

// 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 {
  path: '/approval',
  name: 'approval',
  component: layout,
  children: [
    {
      path: '',
      name: 'approval',
      component: () => import('@/views/approval'),
      meta: {
        title: '审批',
        icon: 'tree-table'
      }
    }
  ]
}

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([
          ...filterRoutes,
          { 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):
