"对象引用未设置为对象的实例"错误从PHP连接到SOAP服务器

Question

我正在尝试从PHP连接到SOAP服务器,我不了解如何登录并获取我需要的数据.我正在尝试连接的服务是Hawley USA服务http://hawleyusa.com/thcServices/StoreServices.asmx).我一直在看几篇关于如何连接的帖子,我得到了基础知识.我已经验证我在PHP中启用了SOAP,而我只是想获得一个库存清单.这是我正在使用的代码:

<?php
ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache
$wsdl_path = "http://hawleyusa.com/thcServices/StoreServices.asmx?WSDL";

$login_id = 'mylogin_id';
$password = 'mypassword';

$client = new SoapClient($wsdl_path);

try {
  echo "<pre>\n";
  print($client->InventoryList(array("LoginID" => $login_id, "Password" => $password)));
  echo "\n";
}
catch (SoapFault $exception) {
  echo $exception;      
} 

但是,当我运行此代码时,我收到此错误:

SoapFault exception: [soap:Server] Server was unable to process request. ---> Object reference not set to an instance of an object. in /Users/steve/Sites/mysite/hawley_client.php:12

在调试时,我可以看到启动了$ client实例,所以我不确定为什么我会收到此错误.

第二个问题:我是否正确传递了用户ID和密码？

谢谢.

更新:我扔了$ client - > __ getLastRequest,这就是我得到的:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"              xmlns:ns1="http://hawleyusa.com/thcServices/">
<SOAP-ENV:Body>
<ns1:InventoryList/>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

所以我可以看到我错过了我的登录ID和密码.如何将它们添加到我的InventoryList调用中？

你很亲密 查看WSDL,InventoryList方法接受一个名为"request"的对象.稍微修改一下你的电话:

$client->InventoryList(array("request" => array("LoginId" => $login_id, "Password" => $password));
