vue3项目如何根据权限动态设置路由和按钮的显示和隐藏
import router from './router'
import { useUserStore } from '@/store/user'
import { usePermissionStore } from '@/store/permission'
import { ElMessage } from 'element-plus'
import NProgress from 'nprogress' // progress bar
import 'nprogress/nprogress.css' // progress bar style
import { getToken } from './utils/storage' // get token from cookie
import getPageTitle from './utils/get-page-title'
NProgress.configure({ showSpinner: false }) // NProgress Configuration
const whiteList = ['/login', '/auth-redirect'] // no redirect whitelist
router.beforeEach(async (to, from, next) => {
// start progress bar
NProgress.start()
// set page title
document.title = getPageTitle(to.meta.title)
// determine whether the user has logged in
const hasToken = getToken()
const userStore = useUserStore()
const permissionStore = usePermissionStore()
if (hasToken) {
if (to.path === '/login') {
// if is logged in, redirect to the home page
next({ path: '/' })
NProgress.done() // hack: https://github.com/PanJiaChen/vue-element-admin/pull/2939
} else {
const hasRoles = userStore.roles && userStore.roles.length > 0
console.log(hasRoles, '是否拥有权限')
if (hasRoles) {
next()
} else {
try {
// 通过token获取用户信息用户权限等等
const { pathArray, frontMenuTree } = await userStore.getInfo()
console.log(pathArray, frontMenuTree, '222')
// 权限路由表
userStore.roles = frontMenuTree
// const accessRoutes = await permissionStore.generateRoutes({ pathArray, frontMenuTree })
// console.log(accessRoutes, '响应结果222')
// accessRoutes.forEach((frontMenuTree) => { router.addRoute(frontMenuTree) })
next({ ...to, replace: true })
} catch (error) {
// remove token and go to login page to re-login
await userStore.resetToken()
ElMessage.error('权限错误')
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()
})
