//懒加载图片插件

//登录拦截，通过vuex中是否有user判断
router.beforeEach((to, from, next) => {
  if (store.state.user.member_id != undefined) {
    console.log('已登录')
    next()
  } else if (to.path != '/login') {
    console.log('to.path not login')
    next('/login')
  } else {
    next()
  }

new Vue({
  store,
  router,
  render: h => h(App)
}).$mount('#app')
