vue3.0如何设置全局路有守卫，感觉我设置的没有问题，但是一直不显示内容

点击登录后，保存token，在router/index.js中添加全局路由守卫，感觉没啥问题，但是启动项目后，登录页面出不来，这是哪里出问题了？代码如下

```html
import {
    createRouter,
    createWebHistory
} from 'vue-router'
const routes = [{
    path: '/',
    name: 'Login',
    component: () => import( /* webpackChunkName: "about" */ '../views/login/Login.vue')
}, {
    path: '/login',
    name: 'Login',
    component: () => import( /* webpackChunkName: "about" */ '../views/login/Login.vue')
}, {
    path: '/about',
    name: 'About',
    // route level code-splitting
    // this generates a separate chunk (about.[hash].js) for this route
    // which is lazy-loaded when the route is visited.
    component: () => import( /* webpackChunkName: "about" */ '../views/About.vue')
}]
const router = createRouter({
    history: createWebHistory(process.env.BASE_URL),
    routes
})
router.beforeEach((to) => {
    // to 指的是我们即将要到达的路由
    // from 是指正在离开的路由
    // 
    const token = sessionStorage.getItem("token")
    console.log(token)
    console.log(to)
    if(to.fullPath!='/'){
        console.log(387492542)
        if (token != null && token != '') {
            to()
        } else {
            console.log(21)
            to.fullPath="/login"
        }
    }
    console.log(38749)
    
})
export default router

感觉没问题啊，请指点一下

少了一个next（），这样就卡住了
