如何在使用ui-router在angularjs应用程序中加载默认状态之前等待身份验证检查

Question

我有一个angularjs应用程序，它使用$ transitions来检查用户是否在某些$状态更改之前进行了身份验证。我使用passport.js来执行身份验证策略。如果未发生身份验证或未通过AuthisLoggedIn（）检查，我希望用户恢复为“登录”状态。州。我遇到的问题是默认状态＆＃39; /＆＃39;似乎总是在我的身份验证承诺之前加载，Auth.getCurrentUserAsync（）执行完毕导致一堆问题。如何强制在等待此身份验证检查时未加载任何状态，然后将用户发送到我的“登录”状态。如果他们在未经过身份验证的所有情况下都会说明。我的代码如下

app.js

clientApp.run(['$transitions', '$state', '$http', 'Auth', '$rootScope',
    function($transitions, $state, $http, Auth, $rootScope) {
        $http.defaults.xsrfHeaderName = 'X-CSRFToken'
        $http.defaults.xsrfCookieName = 'csrftoken'


        $rootScope.baseApiUrl='/app/api'

        //verify the user
        $transitions.onStart(
        {
            to:  function(state) {
                if (typeof state.authenticate !== 'undefined' && state.authenticate === false) {
                    return // this state does not require authentication
                }
                if (!Auth.isLoggedIn()) {

                    Auth.getCurrentUserAsync().then(
                        function() {
                            if (!Auth.isLoggedIn()) {
                                $state.go('login')
                            }
                        }
                    )
                }
            }
        })
}])

clientApp.config(['$urlRouterProvider', '$stateProvider', '$locationProvider',
    function($urlRouterProvider, $stateProvider, $locationProvider) {
        $urlRouterProvider
            .otherwise('/')
        $stateProvider
            .state('main', {
                url: '/',
                component: 'main',
                authenticate: true
            })
            .state('login', {
                url: '/login',
                template: loginTemplate,
                controller: 'LoginCtrl',
                controllerAs: 'Login',
                authenticate: false,
                params: {
                    loginMessage: "",
                    loginErrorMessage: "",
                    username: "",
                    password: undefined,
                    errors: []
                }, 
            })
        $locationProvider.html5Mode(true)
}])
