从PHP调用asp.net Web服务，具有多个参数和验证

Question

我正在尝试使用php soap客户端调用asp.net webservice。但没有成功。 以下是运行正确执行的Web服务的asp代码。

 BASWebService webService = new BASWebService();

                XmlDocument objInput = new XmlDocument();

                objInput.Load(Server.MapPath("FuelDetails.xml"));



                AuthenticationHeader authentication = new AuthenticationHeader();



                authentication.Username = "LTAMSEDI";

                authentication.Password = "LT@2015AMS";

                authentication.strVendorCode = "V0021240";



                string dsData1 = webService.GetEquipmentFuelData(objInput, authentication);

但我怎么能在php中使用我的php代码：

$data1 = file_get_contents('test_xml.xml');
$client = new SoapClient('https://net.lntecc.com/cms/services/BAS/BASWebService.asmx?WSDL', array('trace' => 1,'exceptions' => 0));
$ret = $client->GetEquipmentFuelData($data1, array('classmap' => array(
  'AuthenticationHeader' => array('Username'=>'LTAMSEDI', 'Password'=>'LT@2015AMS', 'strVendorCode' => 'V0021240')
)));

var_dump($ret);

提前致谢.....
