vue-resource请求实现http登录拦截或者路由拦截的方法

export default [
 {
  name: 'root',
  path: '',
  component: function (resolve) {
   require(['你的vue文件路径地址'], resolve);
  },
  children: [
    {
      name: 'applicationLayout',
      path: '/app/applicationLayout/:appId',
      component: function (resolve) {
       require(['你的vue文件路径地址'], resolve);
      },
      meta: {
       requireAuth: true,    // 需要登录才能进入的页面可以增加一个meta属性
      }
    }
  ] 
]

const UNAUTHORIZED_CODE = 401;

router.beforeEach((to, from, next) => {
 if (to.meta.requireAuth) {
  if (storage.get('platformUser')) {
   store.dispatch('loginUser', JSON.parse(storage.get('platformUser')));    //将用户信息存储到vuex中，供全局使用
   next();
  } else {
   store.dispatch('initLoginModal', {state: true});     //显示登录弹窗
   next();
  }
 } else {
  next();
 }
});

//拦截http请求中返回401状态码，并针对其显示登录弹窗
Vue.http.interceptors.push((request, next) => {
 next((response) => {
  if (response.body.status === UNAUTHORIZED_CODE) { //与后台约定登录失效的返回码
   store.dispatch('initLoginModal', {state: true});        //显示登录弹窗
   store.dispatch('removeUser');                      //移出浏览器中存储的用户信息
  }
  return response;
 });
});
