AngularJs - best way to limit access to 'logged in' users

问题

I'm struggling with setting up a login system for an app i'm creating.

I'm able to set cookies for when the user is logged in or out. I don't think that testing every view if the user is logged in is a very elegant solution, and i'm afraid a page here and there may fall through the cracks (it's a rather large app).

I'm thinking the best way would be to intercept route changes somehow and check if the user is logged in, otherwise send them to a login/create user page. I've found a few methods, but nothing seems to be officially documented. Has anyone used this type of method in a real world case, and was it effective?

My route file looks like this:

'use strict';

app.config(['$routeProvider', function ($routeProvider) {
    $routeProvider
        // LOGIN
        .when('/User/LoginUser', {templateUrl: 'views/user/login.html',controller: 'loginCtrl'})

    ....... more routes here.......

        // DEFAULT
        .otherwise({redirectTo: '/'});
}]);

Any help or suggestions, or points to documented real world examples of how I would do something like this would be greatly appreciated!

You can intercept route changes as you suggested and act accordingly, using the following example as a basis:

    $rootScope.$on('$routeChangeStart', function (event, next) {
        var userAuthenticated = ...; /* Check if the user is logged in */

        if (!userAuthenticated && !next.isLogin) {
            /* You can save the user's location to take him back to the same page after he has logged-in */
            $rootScope.savedLocation = $location.url();

            $location.path('/User/LoginUser');
        }
    });

Also, add isLogin: true to the route definition of your login page, like this:

$routeProvider
    // LOGIN
    .when('/User/LoginUser', {templateUrl: 'views/user/login.html',controller: 'loginCtrl', isLogin: true})

Good luck with your project!

My opinion:

<?php if (!$_SESSION['user_id'] { forward(/user/access); }) ?>

and here comes your angular app...
