单路由守卫

从detail页面跳转到login页面的时候，login页面刷新一下
写在router/index.js里

{
  path: '/',
  name: 'detail',
  component: detail,
  meta: {
    title: '智慧用电管理平台'
  }
},
{
  path: '/login',
  name: 'login',
  component: login,
  beforeEnter: (to, from, next) => { // 路由守卫
    if (from.name == 'detail') {
      location.reload()
    }
    next()
  }
},
