Login error with api server

Hello everyone,

I took the Sociogram project will add the login but I get an error : net::ERR_UNKNOWN_URL_SCHEME

My code:

.controller('LoginCtrl', function ($scope, $location, $http, AuthenticationService, OpenFB) {

 
     $scope.model = {};
    $scope.model.emailLog = "";
    $scope.model.passLog="";

    $scope.LoginFormbut = function() {

            $scope.login_error = '';
            $scope.login_success = '';
           
            
           //alert(emailLog+' '+passLog);
           //alert('dans la boucle');
           
                 alert($scope.model.emailLog+' '+$scope.model.passLog);
              
              $http.post('http://UrlMyApi/login',{'email':$scope.model.emailLog,'password':$scope.model.passLog}
               ).success(function(response, message) {
                        if (response= 'true')
                        {
                            $scope.login_success='success';
                            alert('bon mdp');
                        }
                        else
                        {
                            $scope.login_error='Invalid1  Email Address/Password';
                            
                        }
                    }).error(function(response, message) {
                        $scope.login_error='Invalid2 Email Address/Password';
                    });

        };
       
       
    $scope.facebookLogin = function () {

        OpenFB.login('email,read_stream,publish_stream').then(
            function () {
                $location.path('/app/person/me/feed');
            },
            function () {
                alert('OpenFB login failed');
            });
    };

})

My alerts are good but i have this error :
net::ERR_UNKNOWN_URL_SCHEME

Anyone have an idea where it may come? my api should return me : {“response”: true,“message”: “”}

this error with firebug is : [Exception… “” nsresult: “0x805e0006 ()” location: “JS frame :: http://localhost/www/lib/ionic/js/ionic.bundle.js :: createHttpBackend/< :: line 15425” data: no]
