antd pro 4.0 动态菜单

一、BasicLayout.jsx中获取服务端传来的菜单json格式的（需要符合config.js中的路由格式）

/**
 * Ant Design Pro v4 use `@ant-design/pro-layout` to handle Layout.
 * You can view component api by:
 * https://github.com/ant-design/ant-design-pro-layout
 */
import ProLayout, { DefaultFooter, SettingDrawer } from '@ant-design/pro-layout';
import React, { useEffect } from 'react';
import { Link, useIntl, connect } from 'umi';
import { GithubOutlined ,FormOutlined, AccountBookOutlined,UserOutlined,
   SmileOutlined, SettingOutlined,WechatOutlined,GiftOutlined,AppstoreOutlined,
   TeamOutlined,BarsOutlined,DashboardOutlined,WarningOutlined} from '@ant-design/icons';
import { Result, Button } from 'antd';
import Authorized from '@/utils/Authorized';
import RightContent from '@/components/GlobalHeader/RightContent';
import { getAuthorityFromRouter } from '@/utils/utils';
import logo from '../assets/logo.svg';

const noMatch = (
  
        Go Login
      
    }
  />
);

/** 重点：自定义了一个枚举 图标的方法
  原因：后台传过来的icon:string  再菜单中无法显示图标
*/ 
const iconEnum = {
  smile: ,
  setting: ,
  form:  ,
  accountBook:,
  wechat:,
  gift:,
  appstore:,
  team:,
  bars:,
  dashboard:,
  warning:,
  user:,
};

/**
 * use Authorized check all menu item
 */
const menuDataRender = menuList =>
  menuList.map(item => {
    // icon:iconEnum[item.icon]  遍历菜单中图标，转化成可展示的图标
    const localItem = { ...item,icon:iconEnum[item.icon], children: item.children ? menuDataRender(item.children) : [] };
    return Authorized.check(item.authority, localItem, null);
  });

const defaultFooterDom = (
  ,
        href: 'https://github.com/ant-design/ant-design-pro',
        blankTarget: true,
      },
      {
        key: 'Ant Design',
        title: 'Ant Design',
        href: 'https://ant.design',
        blankTarget: true,
      },
    ]}
  />
);

const BasicLayout = props => {


  const {
    dispatch,
    children,
    settings,
    menuData,
    location = {
      pathname: '/',
    },
  } = props;
  /**
   * constructor
   */

  
  useEffect(() => {
    if (dispatch) {
      dispatch({
        type: 'user/fetchCurrent',
      });
      /** 重点：useEffect 相当于生命周期函数
          自己再global.js 中添加一个方法fetchMenu 用来获取服务器传过来菜单列表
       */ 
      dispatch({
        type: 'global/fetchMenu',  
      });
    }
  }, []);
  /**
   * init variables
   */

  const handleMenuCollapse = payload => {
    if (dispatch) {
      dispatch({
        type: 'global/changeLayoutCollapsed',
        payload,
      });
    }
  }; // get children authority

  const authorized = getAuthorityFromRouter(props.route.routes, location.pathname || '/') || {
    authority: undefined,
  };
  const { formatMessage } = useIntl();
  return (
    <>
       (
          
            {logoDom}
            {titleDom}
          
        )}
        onCollapse={handleMenuCollapse}
        menuItemRender={(menuItemProps, defaultDom) => {
          if (menuItemProps.isUrl || menuItemProps.children || !menuItemProps.path) {
            return defaultDom;
          }

          return {defaultDom};
        }}
        breadcrumbRender={(routers = []) => [
          {
            path: '/',
            breadcrumbName: formatMessage({
              id: 'menu.home',
            }),
          },
          ...routers,
        ]}
        itemRender={(route, params, routes, paths) => {
          const first = routes.indexOf(route) === 0;
          return first ? (
            {route.breadcrumbName}
          ) : (
            {route.breadcrumbName}
          );
        }}
        footerRender={() => defaultFooterDom}
        
        //  这个方法就是自定义菜单
        menuDataRender={()=>menuDataRender(menuData)}

        rightContentRender={() => }
        {...props}
        {...settings}
      >
        
          {children}
        
      
      
          dispatch({
            type: 'settings/changeSetting',
            payload: config,
          })
        }
      />
    
  );
};

export default connect(({ global, settings  }) => ({
  collapsed: global.collapsed,
  settings,
  menuData: global.menuData,  // 重点：自己再global.js 中添加一个方法fetchMenu  顶了一个菜单列表state：menuData 
}))(BasicLayout);

二、再global.js中添加一个查询菜单列表的方法

import { queryMenu } from '@/services/user';  // 需要再这个文件中写个请求

const GlobalModel = {
  namespace: 'global',
  state: {
    menuData:[],  // 接受菜单列表
  },
  effects: {

    // 获取菜单
    *fetchMenu(_, { call, put }) {
      const response = yield call(queryMenu);
      yield put({
        type: 'saveMenu',
        payload: response,
      });
    },
  },
  reducers: {
    // 菜单列表
    saveMenu(state, { payload }){
      return {
        collapsed: false,
        ...state,
        menuData: payload.meauList,
      };
    },
};
export default GlobalModel;
