使用PHP的肥皂请求 - 未被捕获的SoapFault异常

Question

致命错误：未捕获的SoapFault异常：[soap：Server] System.Web.Services.Protocols.SoapException：服务器无法处理请求。 ---＆GT; System.NullReferenceException：未将对象引用设置为对象的实例。在ProMail.WebServices.OMS.Order.authenticate（String webServiceName）at ProMail.WebServices.OMS.Order.GetOffers（List 1 sortGroups, String categoryGroupDescription, PMObjectCollection 1 customCategories，String mailerUID，String searchString，Boolean searchID，Boolean searchDescription，String priceClassDescription）at at ProMail.WebServices.OMS.OMS.GetOffers（List 1 sortGroups, String categoryGroupDescription, PMObjectCollection 1 customCategories，String mailerUID，String searchString，Boolean searchID，Boolean searchDescription，String priceClassDescription）---内部异常堆栈跟踪结束---在/ data / 6/1 1/116/96/1930748/user / 2104655 / htdocs / xpedite / Ecwid / soap-test.php：7堆栈跟踪：＃0 / data / 6/1 1/115/96/1930748 / user / 2104655 / htdocs /xpedite/Ecwid/soap-test.php(7）：SoapClient-＆gt; __调用/data/6/1/115/96/1930748/user/2104655/htdocs/xpedite/Ecwid/soap-test.php在线7

 <?php

// http://rhu199.veracore.com/pmomsws/oms.asmx?wsdl
// GetOffers

$client = new soapclient('http://rhu199.veracore.com/pmomsws/oms.asmx?wsdl');
//var_dump($client->__getFunctions()); 
//var_dump($client->__getTypes());

// create an array of parameters 
$param = array(
           'UserName' => "Username",
           'Password' => "Password",
           'searchString' => '%',
           'searchID' => true,
           'searchDescription' => true);

$result = $client->GetOffers($param);

// assess the results 
if (is_soap_fault($result)) {
 echo '<h2>Fault</h2><pre>';
 print_r($result);
 echo '</pre>';
} else {
 echo '<h2>Result</h2><pre>';
 print_r($result);
 echo '</pre>';
}


?>

然后我认为身份验证标头可能是问题并重新编写代码如下，但现在$ params没有被传递。

$apiauth =array('Username'=>'Username','Password'=>'Password');
$wsdl = 'http://rhu199.veracore.com/pmomsws/oms.asmx?wsdl';
$header = new SoapHeader('http://omscom/', 'AuthHeader', $apiauth);
$soap = new SoapClient($wsdl); 
$soap->__setSoapHeaders($header);    

// create an array of parameters 
$params = array(
           'searchString' => '%',
           'searchID' => true,
           'searchDescription' => true);

$data = $soap->GetOffers($header, $params);  

var_dump($data);
