sugarcrm:无法通过扩展现有Web服务从自定义soap服务调用登录

我遵循本教程扩展Sugarcrm Web服务，为我的自定义模块定义新服务。 问题：但是，作为初步检查，我尝试调用现有的登录服务，但它本身失败了。请帮助指出问题所在。我被卡住了

我的教程如下：

正如在教程中提到的，我在custom/service/v4\u 1\u custom文件夹中创建了以下文件

registry.php

<?php
require_once('service/v4_1/registry.php');
class registry_v4_1_custom extends registry_v4_1
{
    protected function registerFunction()
    {
        parent::registerFunction();
        $this->serviceClass->registerFunction('my_get_orders',
        array(
                'session' => 'xsd:string',
                'module_name' => 'xsd:string',
                'id' => 'xsd:string',
        ),
        array(
                'return' => 'xsd:string',
        )
        );
    }
}
?>

<?php
if(!defined('sugarEntry'))define('sugarEntry', true);
    chdir('../../..');
    require_once('SugarWebServiceImplv4_1_custom.php');
    $webservice_class = 'SugarSoapService2';
    $webservice_path = 'service/v2/SugarSoapService2.php';
    $registry_class = 'registry_v4_1_custom';
    $registry_path = 'custom/service/v4_1_custom/registry.php';
    $webservice_impl_class = 'SugarWebServiceImplv4_1_custom';
    $location = 'custom/service/v4_1_custom/soap.php';
    require_once('service/core/webservice.php');    
?>

<?php

    if(!defined('sugarEntry'))define('sugarEntry', true);
    require_once('service/v4_1/SugarWebServiceImplv4_1.php');
    class SugarWebServiceImplv4_1_custom extends SugarWebServiceImplv4_1
    {
        /*
         * Returns the  id if authenticated
         *
         * @param id 
         * @return string $session - false if invalid.
         *
         */
        function my_get_orders($session, $module_name, $id)
        {
            $GLOBALS['log']->info('Begin: SugarWebServiceImplv4_1_custom->my_get_orders');
            $error = new SoapError();

            //authenticate
            if (!self::$helperObject->checkSessionAndModuleAccess($session, 'invalid_session', '', '', '',  $error))
            {
                $GLOBALS['log']->info('End: SugarWebServiceImplv4_1_custom->my_get_orders.');
                return false;
            }
            return $id;
        }
    }
?>

<?php
if(!defined('sugarEntry'))define('sugarEntry', true);
require_once('../include/nusoap/nusoap.php');  //must also have the nusoap code on the ClientSide.


$user_name ='myuser';
$user_password = 'mypassword';
$hostname = 'http://127.0.0.1/sugarcrm/custom/service/v4_1_custom/soap.php?wsdl';

// Create the SOAP client instance
$soapclient = new nusoapclient($hostname, true);
// Login to the server
echo '<b>LOGIN:</b><BR>';
$result = $soapclient->call('login',array('user_auth'=>array('user_name'=>$user_name,'password'=>md5($user_password), 'version'=>'.01'), 'application_name'=>'SoapTest'));


echo '<BR><BR><b>HERE IS RESULT:</b><BR>';
echo print_r($result);
echo var_dump($result);
$session = $result['id'];


echo "sessionid is ".$session;
?>

我将同一组文件放在service/custom下[现有版本直接在service/eg:service/v4\u 1下]

现在它可以工作了，所以之前的情况是文件路径解决问题

HERE IS RESULT:
1
boolean false
sessionid is
