277/300 React+react-router-dom+Vite 二级页面刷新时，白屏问题解决

（一）方案

BrowserRouter 换为 HashRouter

（二）代码

import routes from './routes'
import  {ReactElement, Suspense} from 'react'
import {createHashRouter, Navigate} from 'react-router-dom'
// 生成路由数据
const generateRoutes = (routes:  Routes) => {return routes.map((item: RouteParams) => {const {component: Component} = item;const route: RouteObject = {path: item.path}if (item.redirect) {route.element = <Navigate to={item.redirect} replace/>} else if (Component) {route.element = <BeforeEach meta={item.meta} path={item.path}><Suspense><Component/></Suspense></BeforeEach>}if (item.children) {route.children = generateRoutes(item.children)}return route})
}
export default createHashRouter(generateRoutes(routes)
)

（三）更多代码

import routes from './routes'
import  {ReactElement, Suspense} from 'react'
import {createHashRouter, Navigate} from 'react-router-dom'
// 生成路由数据
const generateRoutes = (routes:  Routes) => {return routes.map((item: RouteParams) => {const {component: Component} = item;const route: RouteObject = {path: item.path}if (item.redirect) {route.element = <Navigate to={item.redirect} replace/>} else if (Component) {route.element = <BeforeEach meta={item.meta} path={item.path}><Suspense><Component/></Suspense></BeforeEach>}if (item.children) {route.children = generateRoutes(item.children)}return route})
}// 路由拦截器
const BeforeEach = (props: { meta?: RouteMeta, children: ReactElement, path: String; }) => {const { userStore } = useStores()const { meta, children, path } = props// 未登录if(meta){if(meta.isAuth && !userStore.isLogin || meta.userStatus && meta.userStatus !== userStore.info.status){return (<AutoReverse path={path} />)}}// 设置标题if (meta?.title) {document.title = meta.title}document.body.style.backgroundColor = meta?.backgroundColor || '';return children
}export default createHashRouter(generateRoutes(routes)
)
