ant design pro(ts) V5 问题2:动态路由图标渲染

直接上代码（关键截取） 全在 src/app.tsx 修改

1:import 添加icon

import  * as Icon from '@ant-design/icons';

2:添加处理图标

const loopMenuItem = (menus: MenuDataItem[]): MenuDataItem[] =>(
    menus.map(({ icon, children, ...item }) => {
        return {
            ...item,
            icon: icon && React.createElement(Icon[icon]),
            children: children && loopMenuItem(children),
            }
    })
);

3:根据动态处理路由方法包裹处理路由icon
