6-2.通用权限系统-权限管理-前端权限对接
硅谷通用权限系统：前端权限对接
一、菜单权限及按钮权限
按照下面步骤即可完成前端框架权限对接
1、修改request.js文件
2、store/modules/user.js
新增菜单及按钮处理
const getDefaultState = () => {
return {
token: getToken(),
name: '',
avatar: '',
buttons: [], // 新增
menus: '' //新增
}
}
const mutations = {
RESET_STATE: (state) => {
Object.assign(state, getDefaultState())
},
SET_TOKEN: (state, token) => {
state.token = token
},
SET_NAME: (state, name) => {
state.name = name
},
SET_AVATAR: (state, avatar) => {
state.avatar = avatar
},
// 新增
SET_BUTTONS: (state, buttons) => {
state.buttons = buttons
},
// 新增
SET_MENUS: (state, menus) => {
state.menus = menus
}
}
// get user info
getInfo({ commit, state }) {
return new Promise((resolve, reject) => {
getInfo().then(response => {
const { data } = response
if (!data) {
return reject('Verification failed, please Login again.')
}
const { name, avatar } = data
commit('SET_NAME', name)
commit('SET_AVATAR', avatar)
commit("SET_BUTTONS", data.buttons)
commit("SET_MENUS", data.routers)
resolve(data)
}).catch(error => {
reject(error)
})
})
}
3、store/getters.js
新增菜单及按钮处理
const getters = {
sidebar: state => state.app.sidebar,
device: state => state.app.device,
token: state => state.user.token,
avatar: state => state.user.avatar,
name: state => state.user.name,
//新增
buttons: state => state.user.buttons,
menus: state => state.user.menus
}
export default getters
4、src/router
先在router这个目录下新建两个js文件，开发环境和生产环境导入组件的方式略有不同
_import_production.js
// 生产环境导入组件
module.exports = file => () => import('@/views/' + file + '.vue')
_import_development.js
// 开发环境导入组件
module.exports = file => require('@/views/' + file + '.vue').default // vue-loader at least v13.0.0+
5、src/permission.js
整体替换该文件
import router from './router'
import store from './store'
import { getToken } from '@/utils/auth'
import { Message } from 'element-ui'
import NProgress from 'nprogress' // 水平进度条提示: 在跳转路由时使用
import 'nprogress/nprogress.css' // 水平进度条样式
import getPageTitle from '@/utils/get-page-title' // 获取应用头部标题的函数
import Layout from '@/layout'
import ParentView from '@/components/ParentView'
const _import = require('./router/_import_'+process.env.NODE_ENV) // 获取组件的方法
NProgress.configure({ showSpinner: false }) // NProgress Configuration
const whiteList = ['/login'] // no redirect whitelist
router.beforeEach(async(to, from, next) => {
NProgress.start()
// set page title
document.title = getPageTitle(to.meta.title)
// determine whether the user has logged in
const hasToken = getToken()
if (hasToken) {
if (to.path === '/login') {
// if is logged in, redirect to the home page
next({ path: '/' })
NProgress.done()
} else {
const hasGetUserInfo = store.getters.name
if (hasGetUserInfo) {
next()
} else {
try {
// get user info
await store.dispatch('user/getInfo')// 请求获取用户信息
if (store.getters.menus.length < 1) {
global.antRouter = []
next()
}
const menus = filterAsyncRouter(store.getters.menus)// 1.过滤路由
console.log(menus)
router.addRoutes(menus) // 2.动态添加路由
let lastRou = [{ path: '*', redirect: '/404', hidden: true }]
router.addRoutes(lastRou)
global.antRouter = menus // 3.将路由数据传递给全局变量，做侧边栏菜单渲染工作
next({
...to,
replace: true
})
//next()
} catch (error) {
// remove token and go to login page to re-login
console.log(error)
await store.dispatch('user/resetToken')
Message.error(error || 'Has Error')
next(`/login?redirect=${to.path}`)
NProgress.done()
}
}
}
} else { /* has no token*/
if (whiteList.indexOf(to.path) !== -1) {
// in the free login whitelist, go directly
next()
} else {
// other pages that do not have permission to access are redirected to the login page.
next(`/login?redirect=${to.path}`)
NProgress.done()
}
}
})
router.afterEach(() => { // finish progress bar
NProgress.done()
}) // // 遍历后台传来的路由字符串，转换为组件对象
function filterAsyncRouter(asyncRouterMap) {
const accessedRouters = asyncRouterMap.filter(route => {
if (route.component) {
if (route.component === 'Layout') {
route.component = Layout
} else if (route.component === 'ParentView') {
route.component = ParentView
} else {
try {
route.component = _import(route.component)// 导入组件
} catch (error) {
debugger
console.log(error)
route.component = _import('dashboard/index')// 导入组件
}
}
}
if (route.children && route.children.length > 0) {
route.children = filterAsyncRouter(route.children)
} else {
delete route.children
}
return true
})
return accessedRouters
}
6、src/router
删除index.js中自定义的路由，以下注释内容即为要删除的内容
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: 'Dashboard', icon: 'dashboard' }
}]
}
//添加我们的路由
// {
// path: '/system',
// component: Layout,
// meta: {
// title: '系统管理',
// icon: 'el-icon-s-tools'
// },
// alwaysShow: true,
// children: [
// {
// path: 'sysRole',
// component: () => import('@/views/system/sysRole/list'),
// meta: {
// title: '角色管理',
// icon: 'el-icon-s-help'
// },
// },
// {
// path: 'sysUser',
// component: () => import('@/views/system/sysUser/list'),
// meta: {
// title: '用户管理',
// icon: 'el-icon-s-help'
// },
// },
// {
// name: 'sysMenu',
// path: 'sysMenu',
// component: () => import('@/views/system/sysMenu/list'),
// meta: {
// title: '菜单管理',
// icon: 'el-icon-s-unfold'
// },
// },
// {
// path: 'assignAuth',
// component: () => import('@/views/system/sysRole/assignAuth'),
// meta: {
// activeMenu: '/system/sysRole',
// title: '角色授权'
// },
// hidden: true,
// }
// ]
// },
// 404 page must be placed at the end !!!
// { path: '*', redirect: '/404', hidden: true }
]
7、src/components
在scr/components目录下新建ParentView文件夹，添加index.vue
<template >
<router-view />
</template>
8、layout/components/SideBar/index.vue
computed: {
...mapGetters([
'sidebar'
]),
routes() {
//return this.$router.options.routes
return this.$router.options.routes.concat(global.antRouter)
},
9、utils/btn-permission.js
在uitls目录添加btn-permission.js文件
import store from '@/store'
/**
* 判断当前用户是否有此按钮权限
* 按钮权限字符串 permission
*/
export default function hasBtnPermission(permission) {
// 得到当前用户的所有按钮权限
const myBtns = store.getters.buttons
// 如果指定的功能权限在myBtns中, 返回true ==> 这个按钮就会显示, 否则隐藏
return myBtns.indexOf(permission) !== -1
}
10、main.js
//新增
import hasBtnPermission from '@/utils/btn-permission'
Vue.prototype.$hasBP = hasBtnPermission
11、按钮权限控制
$hasBP('bnt.sysRole.add')控制按钮是否显示
如：角色管理添加按钮，我们没让按钮隐藏，而是让按钮不可操作
<el-button type="success" icon="el-icon-plus" size="mini" @click="add" :disabled="$hasBP('bnt.sysRole.add') === false">添 加</el-button>
