vue-router路由懒加载和权限控制详解

import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
export default new Router({
 routes: [
  {
   path: '/',
meta: {
requiresAuth: true
},
   ponent: resolve => require(['ponents/Hello.vue'], resolve)
  },
  {
    path: '/about',
    ponent: resolve => require(['ponents/About.vue'], resolve)
  }
 ]
})

//注册全局钩子用来拦截导航

router.beforeEach((to, from, next) => {
 //获取store里面的token
 let token = store.state.token;
 //判断要去的路由有没有requiresAuth
 if(to.meta.requiresAuth){
  if(token){
   next();
  }else{
   next({
    path: '/login',
    query: { redirect: to.fullPath } 
// 将刚刚要去的路由path（却无权限）作为参数，方便登录成功后直接跳转到该路由
   });
  }
 
 }else{
  next();//如果无需token,那么随它去吧
 }
});
