Vue+axios 实现http拦截及路由拦截实例

/** * http配置 */// 引入axios以及element ui中的loading和message组件import axios from 'axios'import { Loading, Message } from 'element-ui'// 超时时间axios.defaults.timeout = 5000// http请求拦截器var loadinginstaceaxios.interceptors.request.use(config => { // element ui Loading方法 loadinginstace = Loading.service({ fullscreen: true }) return config}, error => { loadinginstace.close() Message.error({ message: '加载超时' }) return Promise.reject(error)})// http响应拦截器axios.interceptors.response.use(data => {// 响应成功关闭loading loadinginstace.close() return data}, error => { loadinginstace.close() Message.error({ message: '加载失败' }) return Promise.reject(error)})export default axios

import Vue from 'vue'import Router from 'vue-router'Vue.use(Router)const router = new Router({ routes: [ {  path: '/',  /*  * 按需加载   */  component: (resolve) => {  require(['../components/Home'], resolve)  } }, {  path: '/record',  name: 'record',  component: (resolve) => {  require(['../components/Record'], resolve)  } }, {  path: '/Register',  name: 'Register',  component: (resolve) => {  require(['../components/Register'], resolve)  } }, {  path: '/Luck',  name: 'Luck',   // 需要登录才能进入的页面可以增加一个meta属性  meta: {   requireAuth: true  },  component: (resolve) => {  require(['../components/luck28/Luck'], resolve)  } } ]})// 判断是否需要登录权限 以及是否登录router.beforeEach((to, from, next) => { if (to.matched.some(res => res.meta.requireAuth)) {// 判断是否需要登录权限 if (localStorage.getItem('username')) {// 判断是否登录  next() } else {// 没登录则跳转到登录界面  next({  path: '/Register',  query: {redirect: to.fullPath}  }) } } else { next() }})export default router
