thinkPHP3.2如何用soap连接webservice方法

$url="https://www.test.com/adwebservice.asmx?wsdl";
$client = new \SoapClient($url);

//获取webservice 接口方法

$client->__getFunctions (); 

//获取webservice接口方法的参数类型
$client->__getTypes ();

//执行调用方法

$aryResult = $client->ChangePassword($methodparam);
 var_dump($aryResult);//打印结果

class WebseviceSoap
{
 public function WebService($url,$methodparam=array()){
  try{
    header("content-type:text/html;charset=UTF-8");
   $client = new \SoapClient($url);
   //$client->__getFunctions ();
   //$client->__getTypes ();
   // 参数转为数组形式传
   // 调用远程函数
   $aryResult = $client->ChangePassword($methodparam);
   return (array)$aryResult;
  }catch(Exception $e){
   $aryResult="";
  }
  return $aryResult;
 }
}
