Javascript 本地存储未定义，即使已设置。离子的

我是以这个为例,，

我已经在app.js文件中声明了ng存储。以及：

app.controller('facebookCtrl', ['$cordovaOauth','$scope','$localStorage',function ($cordovaOauth,$scope,oauthService, $localStorage) 
{
$scope.login = function() 
    {
        $cordovaOauth.facebook("1234566878", ["email", "user_location","public_profile"]).then(function(result) {
            $localStorage.currentUser  = result.access_token;

            $http.defaults.headers.common.Authorization = 'Bearer ' +   $localStorage.currentUser ;
            console.log ('acess token is ' + result.access_token)


        }, function(error) {
            alert("There was a problem signing in!  See the console for logs");
            console.log(error);
        });
    };



 }]);

我一直在

无法设置未定义的属性“currentUser”

我已经尝试在开始时启动它，

$localStorage.set（'currentUser'，result.access\u令牌）

仍然不起作用
我用这种方法定义本地存储，它对我来说很有效

app.controller('facebookCtrl', ['$cordovaOauth', '$scope', '$localStorage', function($cordovaOauth, $scope, oauthService, $localStorage) {
    $scope.$storage = $localStorage.$default({
        currentUser = null;
    });
    $scope.login = function() {
        $cordovaOauth.facebook("1234566878", ["email", "user_location", "public_profile"]).then(function(result) {
            $scope.$storage.currentUser = result.access_token;

            $http.defaults.headers.common.Authorization = 'Bearer ' + $localStorage.currentUser;
            console.log('acess token is ' + result.access_token)


        }, function(error) {
            alert("There was a problem signing in!  See the console for logs");
            console.log(error);
        });
    };



}]);

我用这种方法定义了localstorage，它对我很有用

app.controller('facebookCtrl', ['$cordovaOauth', '$scope', '$localStorage', function($cordovaOauth, $scope, oauthService, $localStorage) {
    $scope.$storage = $localStorage.$default({
        currentUser = null;
    });
    $scope.login = function() {
        $cordovaOauth.facebook("1234566878", ["email", "user_location", "public_profile"]).then(function(result) {
            $scope.$storage.currentUser = result.access_token;

            $http.defaults.headers.common.Authorization = 'Bearer ' + $localStorage.currentUser;
            console.log('acess token is ' + result.access_token)


        }, function(error) {
            alert("There was a problem signing in!  See the console for logs");
            console.log(error);
        });
    };



}]);
