// import Home from '../components/home';
// 懒加载方式，当路由被访问的时候才加载对应组件
const Login = resolve => require(['@/components/Login'], resolve)
const Home = resolve => require(['@/components/home'], resolve)
Vue.use(Router)
const router = new Router({
routes: [
{
path: '/',
name: 'login',
component: Login
},
{
path: '/login',
name: 'login',
component: Login
},
{
path: '/home',
name: 'home',
component: Home
}
]})
// 访问之前，检查是否登陆了
router.beforeEach((to, from, next) => {
if(to.path.startsWith('/login')) {
window.sessionStorage.removeItem('user');
next()
}else {
let token = window.sessionStorage.getItem('user');
if (!token) {
next({path: '/login'})
}else {
next()
}
}
});
export default router
至此，运行npm run dev即可
