Angular中使用ui router实现系统权限控制及开发遇到问题

var permissionList; 
angular.element(document).ready(function() { 
$.get('/api/UserPermission', function(data) { 
permissionList = data; 
angular.bootstrap(document, ['App']); 
}); 
});

app.factory('permissions', function($rootScope) {
return {
hasPermission: function(permission) {
if (permission) {
if (typeof(permission) == "string") {
if (permissionList.indexOf(permission) > -1) {
return true;
}
}
}
return false;
}
};
}); 

app.run(function($rootScope, $location,$state, permissions) {
$rootScope.$on('$stateChangeStart', function(event, toState, toParams, fromState, fromParams) {
var permission = toState.permission; 
if (toState.name!="login"&&!permissions.hasPermission(permission)) {
// event.preventDefault();
// $state.transitionTo("login");
}
});
}); 
//路由配置
app.config(function($stateProvider, $urlRouterProvider, $controllerProvider) {
app.registerController = $controllerProvider.register;
app.loadJs = function(js) {
return function($rootScope, $q) {
var def = $q.defer(),
deps = [];
angular.isArray(js) ? (deps = js) : deps.push(js);
require(deps, function() {
$rootScope.$apply(function() {
def.resolve();
});
});
return def.promise;
};
};
$urlRouterProvider.otherwise('/login');
$stateProvider.state('login', {
url: '/login',
templateUrl: '/assets/console/pages/login.html',
controller: 'loginController',
resolve: {
deps: app.loadJs('./controllers/login')
}
});
$stateProvider.state('index', {
url: '/index',
templateUrl: '/assets/console/pages/home.html',
controller: 'indexController',
resolve: {
deps: app.loadJs('./controllers/index')
},
permission: "super_admin"
});
}); 

app.run(['$rootScope', "$state", '$window', '$location', '$log', function($rootScope, $state, $window, $location, $log) {
$rootScope.$on('$stateChangeSuccess',
function(evt, toState, roParams, fromState, fromParams) {
//如果是登录进来就刷新页面
setTimeout(function(){
appCommon.initUI();
},500);
});
}]);
