ui-router - $ state.go（）无效

Here is the app.js of my project:

这是我的项目的app.js:

(function () {
'use strict';

angular
    .module('app', ['ui.router', 'ngCookies', 'angular-inview', 'ngMaterial'])
    .config(config)
    .run(run);

config.$inject = ['$stateProvider', '$urlRouterProvider', '$mdThemingProvider'];
function config($stateProvider, $urlRouterProvider, $mdThemingProvider) {
        $mdThemingProvider.theme('default')
            .primaryPalette('deep-orange')
            .accentPalette('teal', {
              'default': 'A400'
            });

        $urlRouterProvider.otherwise('/app');

        $stateProvider
            .state('app', {
                url: '/app',
                data: {
                    clearenceLevel: 1
                  },
                  views: {
                    '': {
                        templateUrl: 'app/views/navbar.html',
                    }
                }
            })
            .state('home.works', {
                url: '/works',
                templateUrl: 'app/views/works.html',
                controller: 'WorksController as vm'
            })
            .state('login', {
                url: '/login',
                templateUrl: 'app/views/login.html',
                controller: 'LoginController as vm',
                data: {
                    clearenceLevel: 0
                  }
            })
            .state('register', {
                url: '/register',
                templateUrl: 'app/views/register.html',
                controller: 'RegisterController as vm',
                data: {
                    clearenceLevel: 0
                  }
            });
}
run.$inject = ['$rootScope', '$location', '$state', '$cookieStore', '$http', 'AuthenticationService'];
function run($rootScope, $location, $state, $cookieStore, $http, AuthenticationService) {
    $rootScope.globals = $cookieStore.get('globals') || {};

    if ($rootScope.globals.currentUser) {
        $http.defaults.headers.common['aimm-token'] = $rootScope.globals.currentUser.token;
        $http.defaults.headers.common['aimm-id'] = $rootScope.globals.currentUser.id;
    }

    $rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState, fromParams) {
        var clearenceLevel = toState.data.clearenceLevel;
        var loggedIn = $rootScope.globals.currentUser;

        if (clearenceLevel > 0 && !loggedIn) {
            alert("redirecting");
            return $state.go('login');
        }
    });
}
})();

I just can't have $state.go() working. The $on('$stateChangeStart'...); is working fine, and the alert is poping when trying to reach a protected state with no session. But the return $state.go('login'); doesnt work. It redirects to /app.

我只是不能让$ state.go()工作。 $ on('$ stateChangeStart'...);工作正常,当尝试达到没有会话的受保护状态时,警报会弹出。但是返回$ state.go('login');不起作用。它重定向到/ app。

Thanks for your help.

谢谢你的帮助。

Well, thanks to @Vanojx1, I found out adding e.preventDefault(); before the $state.go('login'); made it work. Still dont understand why though.

好吧,多亏了@ Vanojx1,我发现添加了e.preventDefault();在$ state.go('login')之前;使它工作。仍然不明白为什么。

You need to execute the $state.go on main scope and not in a (angular) service or virtual scope created temporarily.

您需要在主范围上执行$ state.go,而不是在临时创建的(角度)服务或虚拟范围中执行。

You can also solve the problem by wrapping it in $timeout or setTimeout which will register it in the browser loop to be executed after the current method run etc even with 0 milliseconds will do it, like.

您也可以通过将其包装在$ timeout或setTimeout中来解决问题,这将在浏览器循环中将其注册,以便在当前方法运行之后执行等,即使用0毫秒也可以执行此操作,例如。

$timeout(()=>{$state.go('xyz')},0)

setTimeout(()=>{$state.go('xyz')},0);
