动态路由刷新出现空白页：

原因：刷新页面的时候动态路由会刷新掉，然后动态路由会重新加载，而匹配路由会在加载路由之前，所以会导致空白页

router.beforeEach(async (to, from, next) => {        const whiteList = ['/login']    let token = store.getters.GET_TOKEN;//token    let hasRoutes=store.state.hasRoutes; //默认是false，刷新页面这个也是false    let menuList=store.getters.GET_MENULIST; //后端返回的菜单列表        if (token) {                if(!hasRoutes){            bindRoute(menuList);//添加动态路由            store.commit("SET_ROUTES_STATE",true);            }        next();    } else {        if (whiteList.includes(to.path)) {            next();        } else {            next('/login');        }    }})//添加动态路由const bindRoute = (menuList) => {    let newRoutes = router.options.routes;    menuList.forEach(menu => {        if (menu.children) {            menu.children.forEach(m => {                // 菜单转成路由                let route = menuToRoute(m, menu.name);                if (route) {                    newRoutes[0].children.push(route); // 添加到路由管理                }            })        }    })    // 重新添加到路由    newRoutes.forEach(route => {        router.addRoute(route)    })}// 菜单转成路由const menuToRoute = (menu, parentName) => {    let route = {        name: menu.name,        path: menu.path,        meta: {            parentName: parentName        },        children:[],    }    if (!menu.component) {        route.component = ''    } else {        route.component = () => import('@/views/' + menu.component + '.vue')    }    return route}

解决办法：递归再调用beforEach，或者直接跳回首页
在你加载路由的地方
递归调用：next({ …to, replace: true });（慎用，如果你的后台管理table是带标签会有问题，没有放对位置会死循环）
跳回首页：next({path:‘/index’})
附上解决的代码：

router.beforeEach(async (to, from, next) => {        const whiteList = ['/login']    let token = store.getters.GET_TOKEN;    let hasRoutes=store.state.hasRoutes;    let menuList=store.getters.GET_MENULIST;        if (token) {        console.log(store.state.editabTabs)        if(!hasRoutes){            bindRoute(menuList);            store.commit("SET_ROUTES_STATE",true);            //next({ ...to, replace: true });//----------解决            next({path:'/index'}); //----------解决            }        next();    } else {        if (whiteList.includes(to.path)) {            next();        } else {            next('/login');        }    }})//添加动态路由const bindRoute = (menuList) => {    let newRoutes = router.options.routes;    menuList.forEach(menu => {        if (menu.children) {            menu.children.forEach(m => {                // 菜单转成路由                let route = menuToRoute(m, menu.name);                if (route) {                    newRoutes[0].children.push(route); // 添加到路由管理                }            })        }    })    // 重新添加到路由    newRoutes.forEach(route => {        router.addRoute(route)    })}// 菜单转成路由const menuToRoute = (menu, parentName) => {    let route = {        name: menu.name,        path: menu.path,        meta: {            parentName: parentName        },        children:[],    }    if (!menu.component) {        route.component = ''    } else {        route.component = () => import('@/views/' + menu.component + '.vue')    }    return route}
