Angularfire facebook OAuth弹出不正常工作

Question

我在我的应用中使用Facebook登录。当用户单击登录按钮时，Facebook登录弹出窗口会闪烁并登录用户，而不显示弹出窗口并询问用户是否要先登录。总之，一旦用户单击登录按钮，他们就会自动登录。我不确定为什么会这样。身份验证工作正常，Facebook返回authData对象。只是弹出窗口没有按我的意愿工作。

这是控制器：

//============AUTHENTICATION CONTROLLER============
myApp.controller("MyAuthCtrl", ["$scope","$rootScope","$firebaseAuth","$location",
  function($scope, $rootScope, $firebaseAuth, $location) {
    var ref = new Firebase("myfirebaseUrl");
    $scope.authObj = $firebaseAuth(ref);

        //============FACEBOOK AUTHENTICATION SCRIPT============
        ref.authWithOAuthPopup("facebook", function(error, authData) {
            if (error) 
            {
                console.log("Login Failed!", error);

                //the function below is necessary to change window location
                $scope.$apply(function() {
                    $location.path('/home');
                });

            } else 
            {
                $rootScope.currentUser = authData;

                //console.log("Authenticated successfully with payload:", authData);
                //console.log("User " + authData.uid + " is logged in with " + authData.provider + "name: " + authData.facebook.displayName);

                //the function below is necessary to change window location
                $scope.$apply(function() {
                    $location.path('/events');   
                });
            }
        });
    }
]);

以下是路线：

var myApp = angular.module("myApp", ["ngRoute","firebase"]);

myApp.config(function($routeProvider){
$routeProvider
    .when("/events",
    {
        controller:"eventsController",
        templateUrl:"partials/events.html"
    })
    .when("/home",
    {
        templateUrl:"partials/home.html"
    })
    .when("/auth",
    {
        controller:"MyAuthCtrl",
        templateUrl:"partials/home.html"
    })
    .otherwise(
    {
        redirectTo:"/home"
    })
});
