            }
        }
    </script>
    <style scoped>
    </style>

## 2 修改路由 index.js ##

import Vue from 'vue'
    import VueRouter from 'vue-router'
    // 导入登录组件
    import Login from "../components/Login";
    // 导入Home 组件
    import Home from "../components/Home";
    // 导入Welcome 组件
    import Welcome from "../components/Welcome";
    // 导入 Users 组件
    import Users from "../components/user/Users";
    import {renderThumbStyle} from "element-ui/packages/scrollbar/src/util";
    
    Vue.use(VueRouter)
    
    const routes = [
        // 路由重定向,当访问/,就会重定向到/login
        {
            path: '/',
            redirect: '/login'
        },
        // 定义登录路由规则
        {
            path: '/login',
            component: Login
        },
        // 定义Home的路由规则
        {
            path: '/home',
            component: Home,
            redirect: '/welcome',
            children: [
                {
                    path: '/welcome',
                    component: Welcome
                },
                {
                    path: '/users',
                    component: Users
                }
            ]
        }
    ]
    
    const router = new VueRouter({
        routes
    })
    // 挂载路由导航守卫
    // to 将要访问的路径
    // from 代表从哪个路径跳转而来
    // next 是个函数，表示放行 next() 放行  next('/login') 强制跳转
    router.beforeEach((to, from, next) => {
        // 如果用户访问的登录页，直接放行
        if (to.path === '/login') return next();
        // 从 sessionStorage 中获取到保存的 token 值
        const tokenstr = window.sessionStorage.getItem('token')
        // 没有 token，强制跳转到登录页
        if (!tokenstr) return next('/login')
        next()
    })
    
    export default router

## 3 修改 Home.vue ##
