在router下面的index.js中添加
meta: {
requireauth: true, // 判断是否需要登录
},
用来判断需要是否登录, 在login也就不用添加了
import Vue from "vue";import VueRouter from "vue-router";import Router from "vue-router";const routes = [{path: "/about",name: "About",component: () =>import(/* webpackChunkName: "about" */ "../views/About.vue"),children: [{path: "/home",name: "home",meta: {requireauth: true, // 判断是否需要登录},component: () =>import(/* webpackChunkName: "home" */ "../views/home/Home.vue"),},}]
在main.js中:
router.beforeEach((to, from, next) => {if (to.matched.some((record) => record.meta.requireauth)) {// 判断该路由是否需要登录权限// console.log("需要登录");if (document.cookie.split("token=")[1]) {// 判断当前的token是否存在 ； 登录存入的tokennext();} else {next({path: "/",query: { redirect: to.fullpath }, // 将跳转的路由path作为参数，登录成功后跳转到该路由});}} else {next();}});
我这里是用token 判断cookie中token是否存在, 不存在的话就跳转到登录页
