“未将对象引用设置为对象的实例"从 PHP 连接到 SOAP 服务器时出错

问题描述

我第一次尝试从 PHP 连接到 SOAP 服务器，但我不明白如何登录并获取我需要的数据.我尝试连接的服务是 Hawley USA 服务 http://hawleyusa.com/thcServices/StoreServices.asmx).我一直在看一些关于如何连接的帖子，我了解了一些基础知识.我已经确认我在我的 PHP 中启用了 SOAP，我只是想获取一个库存列表.这是我正在使用的代码:

";print($client->InventoryList(array("LoginID" => $login_id, "Password" => $password)));回声
";}捕获(SoapFault $exception){回声 $exception;}
但是，当我运行此代码时，出现此错误:
SoapFault 异常:[soap:Server] 服务器无法处理请求.--->你调用的对象是空的.在/Users/steve/Sites/mysite/hawley_client.php:12
在调试时，我可以看到 $client 实例已启动，所以我不确定为什么会出现此错误.
第二个问题:我是否正确传递了用户名和密码?
谢谢.
更新:我输入了 $client->__getLastRequest，这就是我得到的:
所以我可以看到我丢失了我的登录 ID 和密码.如何将它们添加到我的 InventoryList 调用中?
 解决方案 
离你很近了.查看 WSDL，InventoryList 方法采用一个名为请求"的对象.稍微修改您的电话线路:
$client->InventoryList(array("request" => array("LoginId" => $login_id, "Password" => $password));
I'm making my first attempt to connect to a SOAP server from PHP, and I'm not understanding how to log in and get the data I need.  The service I'm trying to connect to is the Hawley USA service http://hawleyusa.com/thcServices/StoreServices.asmx).  I've been looking at a few posts on how to connect, and I get the basics.  I've verified that I have SOAP enabled in my PHP, and I'm just trying to get an inventory list.  Here's the code I'm using:
<?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>
";
  print($client->InventoryList(array("LoginID" => $login_id, "Password" => $password)));
  echo "
";
}
catch (SoapFault $exception) {
  echo $exception;      
} 
However, when I run this code, I get this error:
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
When debugging, I can see the $client instance initiated, so I'm not sure why I'm getting this error.


Second question: Am I passing the user ID and password correctly?

Thanks.

Update: I threw in $client->__getLastRequest, and this is what I got:
<?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>
So I can see that I'm  missing my login ID and password. How do I add them to my InventoryList call?
 解决方案 
You're close. Looking at the WSDL the InventoryList method takes an object called "request". Modify your call line slightly:
$client->InventoryList(array("request" => array("LoginId" => $login_id, "Password" => $password));
