axios拦截器？

// 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

 

设置登陆拦截

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
