angularjs - $rootScope.currentUser 在刷新时为空

Question

我能够让 firebaseSimpleLogin 工作并将当前用户存储在 rootScope 中。当我转到另一个页面并返回提要页面时，所有内容都会加载，但是当我刷新 $rootScope.currentUser 时为空。其他人遇到过这个问题吗？

我的 app.run 函数中有这段代码:

$rootScope.$on('$firebaseSimpleLogin:login',function(e, auth){
   $rootScope.currentUser = User.find(auth.id);
});

这是我的 FeedCtrl 正在尝试加载用户的帖子

app.controller('FeedCtrl',['$scope', '$rootScope','User','Auth','Post',function($scope,     $rootScope,User,Auth,Post){
 populateFeed();
 console.log($rootScope.currentUser);

$scope.logout = function(){
   Auth.logout();
};


$scope.savePost = function(){
  Post.create($scope.post).then(function(post){
    $scope.post.text = "";
  });
};

function populateFeed(){
   $scope.posts = {};
   angular.forEach($rootScope.currentUser.posts,function(id){
    $scope.posts[id] = Post.find(id);
   });
}

}]);

我的主应用模块

var app = angular.module('myapp',['ui.router','firebase']);

app.config(function($stateProvider, $urlRouterProvider){
  $stateProvider
.state('/',{
  url: '/',
  controller: 'MainCtrl',
  templateUrl: 'views/index.html'
})
.state('feed',{
  url: '/feed',
  controller: 'FeedCtrl',
  templateUrl: 'views/feed.html',
  authenticate: true
})
.state('login',{
  url: '/login',
  controller: 'LoginCtrl',
  templateUrl: 'views/login.html'
})
.state('signup',{
  url: '/signup',
  controller: 'LoginCtrl',
  templateUrl: 'views/signup.html'
})
.state('settings',{
  url: '/settings',
  controller: 'SettingsCtrl',
  templateUrl:"views/settings.html"
})
.state('profile',{
  url: '/:slug',
  controller: 'ProfileCtrl',
  templateUrl: 'views/profile.html'
})
.state('profile-about',{
  url: '/:slug/about',
  controller: 'ProfileCtrl',
  templateUrl: 'views/profile.html'
});

$urlRouterProvider.otherwise('/');
})
.constant('FIREBASE_URL','https://{FIREBASE}.firebaseio.com/')
.run(function($rootScope, $state,FIREBASE_URL, $firebaseSimpleLogin, User, Auth){
$rootScope.$on('$stateChangeStart',function(event, next){
  if(next.authenticate && !User.getCurrentUser()){
     $state.go('login');
  }
 });

 $rootScope.$on('$firebaseSimpleLogin:login',function(e, auth){
   $rootScope.currentUser = User.find(auth.id);
  });

 $rootScope.$on('$firebaseSimpleLogin:logout',function(){
  delete $rootScope.currentUser;
  $state.go('login');
 });

 $rootScope.logout = function(){
  Auth.logout();
};

});

要将其存储在 localStorage 中:
$window.localStorage.setItem("currentUser", currentUser);

或以 json 格式存储:
$window.localStorage.setItem("currentUser", angular.toJson(currentUser));

在那里得到它:
var currentUser = $window.localStorage.getItem("currentUser");

或者如果您使用第二种方式保存它:
var currentUser = JSON.parse($window.localStorage.getItem("currentUser"));
