这是一个轻量级的优化用户体验工具，我们先引入他的第三方依赖工具。

2 路由文件中引入依赖

import NProgress from 'nprogress'
import 'nprogress/nprogress.css'
NProgress.configure({
  easing: 'ease', // 动画方式
  speed: 500, // 递增进度条的速度
  showSpinner: false, // 是否显示加载ico
  trickleSpeed: 200, // 自动递增间隔
  minimum: 0.3 // 初始化时的最小百分比
})
// 当路由进入前
router.beforeEach((to, from, next) => {
  // 每次切换页面时，调用进度条
  NProgress.start()
  // 这个一定要加，没有next()页面不会跳转的。这部分还不清楚的去翻一下官网就明白了
  next()
})
// 当路由进入后：关闭进度条
router.afterEach(() => {
  // 在即将进入新的页面组件前，关闭掉进度条
  NProgress.done()
})

export default router;

Vue.use(Router)

//获取原型对象上的push函数,多次点击路由地址不对报错问题，相当于重置路由。
const originalPush = Router.prototype.push
//修改原型对象中的push方法
Router.prototype.push = function push(location) {
