vue-router实现路由管理的一些笔记

router.beforeEach((to, from, next) => {

let token = sessionStorage.getItem('token');           	//通过存入一个token来判断用户是否登录
if (!token && to.path != '/login') {
sessionStorage.removeItem('token');
next({path: '/login'})                                    //如果没有seesion 和不是从登录进来的 全部重定向为login
console.log('没有sess 或者不是登录进路由' + sessionStorage.getItem('token'))
} else {
if (sessionStorage.getItem("isLogin") == "1" && to.path == '/login') {
next({path: '/showActivity'});
Message({
message: '已返回最前,重新登录请点击右上角头像注销',
type: 'warning'
});
console.log('登录状态为已登录 且返回login时 给他重定向为showActivity')
} else {
next()
}

if (sessionStorage.getItem("vuexState")) {
sessionStorage.removeItem("vuexState")
switch (sessionStorage.getItem('token')) {
//这里由于存入session JSON格式转过后vue解析不了转换过后的路由component
//采取暴力添加routes

case 'admin':
console.log('执行了admin刷新')
router.addRoutes([
{
path: '/',
