fix: next to login when token is not right

src/permission.js

 import store from './store'
 import NProgress from 'nprogress' // Progress 进度条
 import 'nprogress/nprogress.css'// Progress 进度条样式
+import { Message } from 'element-ui'
 import { getToken } from '@/utils/auth' // 验权
 
 const whiteList = ['/login'] // 不重定向白名单
       if (store.getters.roles.length === 0) {
         store.dispatch('GetInfo').then(res => { // 拉取用户信息
           next()
+        }).catch(() => {
+          store.dispatch('FedLogOut').then(() => {
+            Message.error('验证失败,请重新登录')
+            next({ path: '/login' })
+          })
         })
       } else {
         next()
