1.按照之前的全局初始菜单数据的方式来加载动态菜单,发现有一个bug,就是登录后,菜单数据不能正常显示(菜单位置空白),需要页面刷新一下,菜单才能正常显示。
2.调试了一下,发现跳转到登录页面后,会执行app.jsx中的getInitialState方法,但是这时候没有正常登录,是没法获取到菜单信息的,但是点登录按钮以后,跳到首页以后并未执行getInitialState()方法获取菜单信息,刷新下页面后又会执行getInitialState(),加载菜单。
3.未定位到具体的解决办法,又搜索了Antd pro V5的官网,从服务器加载 menu,官网示例代码中有一段示例代码如下:
<ProLayoutstyle={{height: '100vh',border: '1px solid #ddd',}}actionRef={actionRef}menu={{request: async () => {await waitTime(2000);return customMenuDate;},}}location={{pathname: '/welcome/welcome',}}>
其中Layout的menu可以使用request异步加载服务端的菜单信息。
4.按官网的示例重新修改app.jsx,去掉之前的fetchUserMenus,参照官网示例,改在Layout中使用menu获取菜单信息,同时保留原来的图标封装方法,修改后的app.jsx完整代码如下:
import { PageLoading } from '@ant-design/pro-layout';import { history, Link } from 'umi';import RightContent from '@/components/RightContent';import Footer from '@/components/Footer';import { currentUser as queryCurrentUser } from './services/ant-design-pro/api';import { BookOutlined, LinkOutlined } from '@ant-design/icons';import { requestInterceptors, responseInterceptors, errorHandler } from '@/utils/Request';import { getCurrentUserMenus } from './services/ant-design-pro/menu';import fixMenuItemIcon from '@/utils/fixMenuItemIcon';const isDev = process.env.NODE_ENV === 'development';const loginPath = '/user/login';/** 获取用户信息比较慢的时候会展示一个 loading */export const initialStateConfig = {loading: <PageLoading />,};/*** @see https://umijs.org/zh-CN/plugins/plugin-initial-state* */export async function getInitialState() {const fetchUserInfo = async () => {try {const msg = await queryCurrentUser();console.log("login user info:",msg);return msg.user;} catch (error) {history.push(loginPath);}return undefined;};if (history.location.pathname !== loginPath) {const token = localStorage.getItem('access_token');if (!token) {history.push(loginPath);return {fetchUserInfo,currentUser:{},settings: {},};}const currentUser = await fetchUserInfo();return {fetchUserInfo,currentUser,settings: {},};}return {fetchUserInfo,currentUser,settings: {},};}// ProLayout 支持的api https://procomponents.ant.design/components/layoutexport const request = {errorHandler,requestInterceptors: [requestInterceptors],responseInterceptors: [responseInterceptors],};export const layout = ({ initialState,setInitialState }) => {return {rightContentRender: () => <RightContent />,disableContentMargin: false,waterMarkProps: {content: initialState?.currentUser?.name,},footerRender: () => <Footer />,onPageChange: () => {const { location } = history; // 如果没有登录,重定向到 loginif (!initialState?.currentUser && location.pathname !== loginPath) {history.push(loginPath);}},links: isDev? [<Link to="/umi/plugin/openapi" target="_blank"><LinkOutlined /><span>OpenAPI 文档</span></Link>,<Link to="/~docs"><BookOutlined /><span>业务组件文档</span></Link>,]: [],menuHeaderRender: undefined,menu: {// 每当 initialState?.currentUser?.userId 发生修改时重新执行 requestparams: {userId: initialState?.currentUser?.userId,},request: async (params, defaultMenuData) => {// initialState.currentUser 中包含了所有用户信息const tempMenuData = await getCurrentUserMenus();const menuData=fixMenuItemIcon(tempMenuData);return menuData;},},...initialState?.settings,};};
其中去掉了之前的fetchUserMenus相关代码,在layout中获取后台菜单数据并加载显示的核心代码如下:
menu: {// 每当 initialState?.currentUser?.userid 发生修改时重新执行 requestparams: {userId: initialState?.currentUser?.userId,},request: async (params, defaultMenuData) => {// initialState.currentUser 中包含了所有用户信息const tempMenuData = await getCurrentUserMenus();const menuData=fixMenuItemIcon(tempMenuData);return menuData;},},
其中getCurrentUserMenus和fixMenuItemIcon之前已做过封装。
5.前台代码修改后,重新编译运行,登录后菜单正常显示。
