角UI路由器$ state.go是不是里面的决心重定向

问题描述：

在我angularjs的应用程序，我检查目标网页上，如果用户的土地和已经验证，然后重定向他的主页。

In my angularjs app, I am checking if user lands on landing page and is already authenticated, then redirect him to home page.

.state('landingpage', {
            abstract: "true",
            url: "/landingpage",
            templateUrl: "app/landingpage/landingpage.html",
            resolve: {
                AutoLoginCheck: ['$state', '$window', function ($state, $window) {

                    if($window.localStorage.access_token != null)
                    {
                        if($window.sessionStorage.access_token == null) {
                            $window.sessionStorage.access_token = $window.localStorage.access_token;
                        }
                        UserInfoService.SetUserAuthenticated(true);

                        // it is not redirecting
                        return $state.go('app.home');

                    }
                }]
            }
        })

问题是，尽管所有的决心code为成功运行，用户没有得到重定向到app.home。谁能告诉为什么发生这种情况？

The problem is that though all the resolve code is successfully run, user is not getting redirected to app.home. Can someone tell why this happens?

注意：国家应用也有它的获取要显示的数据的解析app.home状态

Note: The state 'app' also has a resolve in which it fetches the data to be displayed in 'app.home' state.

答

有可能是两个解决您的问题。

There can be two solutions to your problem

首先，你可以发出一个事件和监听器将处理您的状态转变。您可以实现在一个父控制器随时随地收听

Firstly you can emit an event and the listener will handle your state transition. You can implement the listener in anywhere in a parent controller

其次，你可以实现$ stateChangeStart挂钩，并检查您的重定向状态有

Secondly you can implement the $stateChangeStart hook and check your redirection condition there

$ rootScope。在$（'$ stateChangeStart'，函数（事件，toState）{结果
           如果（toState.name ==='的LandingPage'）{结果
             如果（！isAuthenticated（））{//检查用户是否允许转型结果
                  。事件preventDefault（）; // prevent迁移到默认状态结果
                  $ state.go（'home.dashboard'）;结果
              }
            }
  }）;

$rootScope.$on('$stateChangeStart', function (event, toState) {
if (toState.name === 'landingpage') {
if (!isAuthenticated()) { // Check if user allowed to transition
event.preventDefault(); // Prevent migration to default state
$state.go('home.dashboard');
} } });
