后端传递的图标是字符串形式的 Ant Design 图标组件怎么避免被解析为普通文本

问题描述

后端传递导航，数据格式带了icon。如下

const superNav = [
            {
              key: '1',
              icon: '<AppstoreOutlined />',
              title: '控制台',
              link: '/console',
            },
            {
              key: '2',
              icon: '<UserOutlined />',
              title: '账号管理',
              children: [
                {
                  key: 'sun1',
                  title: '权限管理',
                  link: '/account/permission',
                },
                {
                  key: 'sun3',
                  title: '用户管理',
                  link: '/account/role',
                },
              ],
            },
        ];

不做处理渲染的话结果如下

解决方案

导入需要的antd组件，在拿到后端数据后把原本的icon字符串替换为antd对应的icon组件

import {
  UserOutlined,
  SecurityScanOutlined,
  IdcardOutlined,
  AppstoreOutlined,
} from '@ant-design/icons';

//省略

  const getNavList = ()=>{
      let navList = navData.filter((item,index)=>{
          if(item.icon=='<AppstoreOutlined />'){
            item.icon = <AppstoreOutlined />
          }else if(item.icon=='<SecurityScanOutlined />'){
            item.icon = <SecurityScanOutlined />
          }else if(item.icon=='<IdcardOutlined />'){
            item.icon = <IdcardOutlined />
          }else if(item.icon=='<UserOutlined />'){
            item.icon = <UserOutlined />
          }
          return item
      })
      setMenuData(navList)
  }
