?将项目路由拆分为:
- 静态路由:login、404、home、screen
- 异步路由:权限管理(包含三个子路由)、商品管理(包含四个子路由)
- 任意路由:任意路由

?PS:退出登录记得删除添加的路由,防止切换角色后还能访问另一个角色的权限
src/store/modules/user.ts
......
// 引入路由(常量路由)
import { constantRoute, asnycRoute, anyRoute } from '@/router/routes'
// 引入深拷贝方法
//@ts-expect-error
import cloneDeep from 'lodash/cloneDeep'
import router from '@/router'
// 用于过滤当前用户需要展示的异步路由
function filterAsyncRoute(asnycRoute: any, routes: any) {
return asnycRoute.filter((item: any) => {
if (routes.includes(item.name)) {
if (item.children && item.children.length > 0) {
item.children = filterAsyncRoute(item.children, routes)
}
return true
}
})
}

const useUserStore = defineStore('User', {
// 小仓库存储数据的地方
state: (): UserState => {
return {

menuRoutes: constantRoute, // 仓库存储生成菜单需要数组(路由)
removeRouteCallbackList: []
}
},
// 异步|逻辑的地方
actions: {

// 获取用户信息
async userInfo() {

let result: userInfoResponeData = await reqUserInfo()

// 菜单需要的数据整理完毕
this.menuRoutes = [...constantRoute, ...userAsyncRoute, anyRoute]
// 目前路由器管理的只有常量路由:用户计算完毕异步路由、任意路由动态追加

this.removeRouteCallbackList.push(removeRoute)
})
return 'ok'
} else {

}
},
// 退出登录
async userLogout() {
let result: any = await reqLogout()
if (result.code === 200) {
// 目前没有mock接口:退出登录接口(通知服务器本地用户唯一标识失败)
this.token = ''
this.username = ''

})
刷新的时候是异步路由,有可能获取到用户信息,异步路由还没有加载完毕,出现空白的效果!!
解决方法:在全局前置守卫中,获取用户信息后改成next({...to})
- next()?:直接放行(这种写法会导致刷新产生空白的效果)
- next({...to}):等待路由加载完毕再放行
src/permission.ts
......
try {
// 获取用户信息
await useStore.userInfo()
// 放行
//等待路由加载完毕再放行
next({ ...to})
} catch (error) {
}
.......
src/store/modules/user.ts?
......
state: (): UserState => {
return {
......
//存储当前用户是否包含某一个按钮
buttons: [],
}
......
async userInfo() {
......
// 如果获取信息成功,存储下用户信息
if (result.code === 200) {
......
this.buttons = result.data.buttons
......
}
src/directive/has.ts?
import pinia from "@/store"
import useUserStore from "@/store/modules/user"
const userStore = useUserStore(pinia)
export const isHasButton = (app: any) => {
// 获取对应的用户仓库
// 全局自定义指令:实现按钮的权限
app.directive('has', {
// 代表使用这个全局指令的DOM|组件挂载完毕的时候会执行一次
mounted(el: any, options: any) {
// 自定义指令右侧的数值:如果在用户信息buttons数组中没有
// 从DOM树上干掉
if (!userStore.buttons.includes(options.value)) {
el.parentNode.removeChild(el)
}
},
})
}
?在main.ts文件中引入自定义指令文件
// 引入自定义指令文件
import { isHasButton } from '@/directive/has'
isHasButton(app)
PS:此处以其中一个按钮作为例子,项目中其他按钮的权限都需要配置
<el-button type="primary" size="default" icon="Plus" @click="addTrademark" v-has="'btn.Trademark.add'">
