Vue错误 TypeError: Cannot read properties of undefined (reading 'roles')

后发现是 const { roles } = await store.dispatch('user/getInfo') 用户已经过期获取不到值导致.

if (to.path === '/login') { // if is logged in, redirect to the home page next({ path: '/' }) NProgress.done() } else { // determine whether the user has obtained his permission roles through getInfo const hasRoles = store.getters.roles && store.getters.roles.length > 0 if (hasRoles) { next() } else { try { // get user info // note: roles must be a object array! such as: ['admin'] or ,['developer','editor'] const { roles } = await store.dispatch('user/getInfo') // generate accessible routes map based on roles const accessRoutes = await store.dispatch('permission/generateRoutes', roles) // dynamically add accessible routes router.addRoutes(accessRoutes) // hack method to ensure that addRoutes is complete // set the replace: true, so the navigation will not leave a history record next({ ...to, replace: true }) } catch (error) { // remove token and go to login page to re-login // await store.dispatch('user/resetToken') Message.error(error || 'Has Error') next(`/login?redirect=${to.path}`) NProgress.done() } } } } else { /* has no token*/ if (whiteList.indexOf(to.path) !== -1) { // in the free login whitelist, go directly next() } else { // other pages that do not have permission to access are redirected to the login page. next(`/login?redirect=${to.path}`) NProgress.done() } }
