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 loadinginstace
axios.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 
  */

  name: 'Register',
  component: (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()
