AngularJS：将用户重定向到不同的视图,无论他是否登录

>登录视图’/ login’
>主页查看’/ home’
>登录主页视图’/仪表板’

当用户登录后导航到主页时,我想向他显示登录主页.我尝试将redirectUrl提供给$routeProvider.如果我返回一个空字符串,它会停留在页面上,如果它返回一个像’/ dashboard’这样的字符串,那么它会重定向到仪表板.

问题是我无法检查用户是否已登录,在配置中的该功能.因为我不能在那里注入我的UserService.

main.js

var myApp = angular.module('myApp',['ngRoute','ngAnimate']);

myApp.config(['$routeProvider','$locationProvider',function AppConfig($routeProvider,$locationProvider) {

    $routeProvider.when(
        // entry point,the main route of the app
        '/',{
            redirectTo: '/home'
        }
    )
    .when(
        // home page,entrypoint when a user is not logged in.
        '/home',{
            redirectTo: function redirectHome() {
                // need to get the loggedInState here... preferably not on the window :p
                return (window.isLoggedIn) ? "/dashboard" : "";
        },action: 'splash.home'
        }
    )
    .when(
        // specific route to the login popup on the homepage
        '/login',{
            action: 'splash.home.login'
        }
    )
    .when(
        // dashboard after being logged in
        '/dashboard',{
            action: 'base.dashboard'
        }
    )
});

保存用户状态的UserService：

myApp.service('UserService',[
        '$http',function UserService($http) {

            // --- Service Variables. ------------------- //

            // url to the service that returns the logged in user details
            var userServiceUrl = '/user/data/me';

            // Store the current user.
            var User = {
                isLogged: false,apps: [],data: {}
            };

            // --- Service Methods. ------------------- //

            // Return whether the user is logged in
            function isLoggedIn() {
                return User.isLogged;
            }

            // Return the current user
            function getUser(fn) {
                fn = fn || function callback() {};

                if (!User.isLogged) {
                    return fetchUser(fn);
                } else {
                    return fn(User);
                }
            }

            // set the current user
            function setUser(user,loggedIn) {
                loggedIn = loggedIn || false;
                User.isLogged = loggedIn;
                User.data = user;
            }

            // get the user from the server
            function fetchUser(fn) {
                $http.get(userServiceUrl).success(function onGetUserSuccess(data,status,headers,config) {
                    if (data.success) {
                        setUser(data.data,data.success);
                    }

                    if (fn !== undefined) {
                        fn(User);
                    }
                })
                .error(function onGetUserError(data,config) {
                    setUser({},false);
                });
            }

            // --- Return Public API. ------------------- //

            return {
                isLoggedIn: isLoggedIn,getUser: getUser,setUser: setUser
            };

        }
    ]
);

有没有办法从配置进入用户状态？没有它是公开的(我不想让窗口对象上的用户可访问…例如…)

或者我应该从cookie或其他系统获取该信息？
