Angular Resolve中的服务$ stateProvider

Question

我正在尝试使用resolve并将其注入factory，然后在controller中打印解析返回的数据。

基本上代码看起来很像：

 angular
        .module('appRouter',['ui.router'])
        .controller('routerCtrl',function(resolveData){
            console.log(resolveData);

        })
        .factory('repoService',function($http){
            var API = "https://jsonplaceholder.typicode.com/posts/1";
            return {
                getResolveData : function($http){
                    return $http.get(API);
                }
             }
        })
        .config(function($stateProvider,$urlRouterProvider){
            $stateProvider
                .state('settings.profile',{
                    url:'/profile',
                    templateUrl:'templates/profile.html'
                })
                .state('settings.account',{
                    url:'/account',
                    templateUrl:'templates/account.html',
                    controller:'routerCtrl',
                    controllerAs:'vm',
                    resolve:{
                        resolveData : function(repoService){
                            return repoService.getResolveData().then(function(response){
                                return response.data;
                            });
                        }
                    }
                });

            $urlRouterProvider.otherwise('/settings/profile');  

        });

但代码不起作用。 No error in console but the routing to settings/account does not work . And nothing is printed on the console.

BUT

如果我们在不注入服务的情况下执行此操作，则以下代码可以正常工作。

            .state('settings.account',{
                url:'/account',
                templateUrl:'templates/account.html',
                controller:'routerCtrl',
                controllerAs:'vm',
                resolve:{
                    resolveData : function(){
                         var root = 'https://jsonplaceholder.typicode.com';
                         return $http.get(root+'/posts/1').then(function(response){

                             return response.data;
                         });
                    }
                }
            });

我无法弄清楚我做错了什么？请解释一下。
