        //if (loginData.rememberMe) {
        data = data + "&client_id=" + constants.AUTHSETTINGS.CLIENT_ID;
        //}
        debugger;
        console.log(data)

        var deferred = $q.defer();
        $http.post(api_url + '/token', data, { 
            headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
         })
        .then
        (function (response) {
            if (loginData.rememberMe) {
                localStorageService.set('authorizationData', { token: response.data.access_token, userName: loginData.userName, refreshToken: response.data.refresh_token, useRefreshTokens: true });
            }
            else {
                localStorageService.set('authorizationData', { token: response.data.access_token, userName: loginData.userName, refreshToken: "", useRefreshTokens: false });
            }
            console.log('---auth servcie')
            console.log(response)
            authentication.isAuth = true;
            authentication.userName = loginData.userName;
            authentication.useRefreshTokens = loginData.rememberMe;

            deferred.resolve(response);
        }
        ,function (err, status) {
                console.log('auth error -- here ')
                console.log(err)
                console.log(status)
                deferred.reject(err);
                //deferred.resolve(err);
            });


        return deferred.promise;
    };
