my requirement is that the user opens the page, determines whether the index page (/ default is index) has login status, and continues without jumping login,. Now the problem is that I can"t block it by opening the index connector by default, and next directly. Then I click on other routes and intercept them when they return to the index page. What"s the problem? why can"t I intercept
in the first place?you can use beforeEach as a routing guard
router.beforeEach((to, from, next) => {
// to and from are both route objects
let login = sessionStorage['token'] || null
let path = to.path
if (path === '/login') {
next()
return
}
// to.meta.requireAuth
let requireAuth = to.meta.requireAuth
if (requireAuth) { //
if (!login) { //
next({
path: '/login'
})
} else { //
next()
}
} else { //
next()
}
})just can t show it. Thank you very much for your advice. ...
