解决ANTD PRO VUE，切换用户之后，左侧菜单不刷新问题

文件路径 src/store/modules/permission.js

// 从lodash中引入深拷贝
import cloneDeep from "lodash.clonedeep";

//修改此函数
function filterAsyncRouter(routerMap, roles) {
  // 增加此行是因为如果不深拷贝，会更改原路由表，当切换用户时，会出现用户该有的菜单无法显示
  let asyncRouterMap = cloneDeep(routerMap);
  const accessedRouters = asyncRouterMap.filter(route => {
    if (hasPermission(roles.permissionList, route)) {
      if (route.children && route.children.length) {
        route.children = filterAsyncRouter(route.children, roles);
      }
      return true;
    }
    return false;
  });
  return accessedRouters;
}
