VUE 刷新页面404

系统可以正常登录，但是刷新页面404

export default new Router({
  mode: 'history',
  scrollBehavior: () => ({ y: 0 }),
  base: !window.__POWERED_BY_QIANKUN__ ? '/sxxxxx' : '',
  routes: constantRouterMap
})

修改mode为hash模式 页面可以正常刷新

export default new Router({
  scrollBehavior: () => ({ y: 0 }),
  routes: constantRouterMap
})
