Vue+axios 实现http拦截及路由拦截实例

{ // 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

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'],{
  path: '/Register',name: 'Register',component: (resolve) => {
  require(['../components/Register'],{
  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
