您可以拦截路由变化如你所说，并采取相应的行动，使用下面的示例作为基础：

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');
        }
    });

此外，添加 isLogin：真正的来登录页面的路由定义，像这样的：

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})

祝你的项目！
