Firebase在页面刷新时未触发$rootScope.$on($firebaseSimpleLogin:login)？

Question

它会在我登录时触发，在我登录时触发，但在页面刷新时不再触发？我应该如何设置将触发的函数？

似乎当我刷新页面时，它会重新连接并重新进行身份验证(参见下面的firebase日志)，但(我的猜测是)不会触发

0: event:/users:{"ep":"simplelogin:145","sp":"simplelogin:145"}:value 

怎么回事？

谢谢，瑞恩

控制器：

'use strict';

angular.module('ccApp.services.user', ['ccApp.services.auth'])
    .factory('User', ['$firebase', '$rootScope', 'FBURL',
      function($firebase, $rootScope, FBURL){
        var ref = new Firebase(FBURL + '/users');

        var users = $firebase(ref);

        var User = {
          create: function (authUser, name) {
            /* jshint camelcase: false */
            console.log(authUser.id);
            console.log(authUser.user);
            users[authUser.id] = {
              md5_hash: authUser.md5_hash,
              name: name,
              $priority: authUser.uid
            };

            users.$save(authUser.id).then(function () {
              console.log(authUser.id);
              setCurrentUser(authUser.id);
            });
          },

          findByUserId: function (userId) {
            if (userId) {
              return users.$child(userId);
            }
          },

          getCurrent: function () {
            return $rootScope.currentUser;
          },

          signedIn: function () {
            return $rootScope.currentUser !== undefined;
          }

        };


        function setCurrentUser (userId) {
          $rootScope.currentUser = User.findByUserId(userId);
        }

        $rootScope.$on('$firebaseSimpleLogin:login', function (e, authUser) {
          console.log("trigger userservice - $firebaseSimpleLogin:login");
          var query = $firebase(ref.startAt(authUser.uid).endAt(authUser.uid));

          query.$on('loaded', function () {
            setCurrentUser(query.$getIndex()[0]);
          });
        });

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

        return User;

      }]);

Answer 1

遵循thinkster tutorial, part 7时遇到相同问题。

它是通过注入User修复的。在本教程中，这就是下一步(希望有人能够避免这个小小的障碍，这要归功于我的愚蠢)。

但通常情况下，导致问题的原因是User服务没有注入到页面上的任何控制器中，因此$rootScope.$on('$firebaseSimpleLogin:login' ...侦听器没有被注册，因此没有触发。
