AngularJs-如果已经登录，则跳过登录页面

Question

I have implemented an Authentication system for my app. I use $routeChangeStart (in run) to check if the user is logged in and redirect him to login if not. This works fine. But, I can access the login page via the url, I want to send the user to the dashboard if he's already logged in. What is the proper way to do this?

Answer 1

Guys try this elegant solution:

.run(function ($rootScope, $location, authService) {
        $rootScope.$on('$stateChangeStart', function (ev, to, toParams, from, fromParams) {
            if (to.requireAuth && !authService.isAuthed()) {
                $location.path("/login");
            }
            else if (to.name == 'login' && authService.isAuthed()) {
                ev.preventDefault();
                $location.path("/dashboard");
            }
        });
    })

• if the user is not logged in and login is required it redirect to login.
• if the user try to get to login and he already logged in, prevent him from doing it.
• mark every path as "requireAuth" and it will work.
• place your code in app.js

Try

$rootScope.$on('$locationChangeStart', function(event, newUrl, oldUrl) {});
