我正在尝试使用PHP和nusoap将数据提交到Web服务。我正在呼叫的Web服务操作位于：http://service.leads360.com/ClientService.asmx?op=AddLeads
操作的预期参数为username为字符串，password为字符串，leads为XmlNode。对于这个XmlNode，他们提供了schema和xml doc的示例：
http://service.leads360.com/Documentation/Schemas/Client/Leads.Request.xsd
http://service.leads360.com/Documentation/Examples/Client/AddLeads.leads.xml
所以我复制了他们提供的xml doc并将其转换为数组，将该数组放在另一个名为$params的数组中，同时放入username和password并执行
$result = $client->call('AddLeads', $params);
不幸的是它给了我以下错误：
[faultcode] => soap:Server
[faultstring] => System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.NullReferenceException: Object reference not set to an instance of an object.

我将代码粘贴到：http://pastebin.com/7jbPGuqn。
我也粘贴了我传递的数组作为下面的引导参数。请告诉我数组是否代表示例中的xml文档，以及它是否为有效的XmlNode。

与值为int或string的简单元素不同，XmlNode是一个更复杂的结构，它是一个XML元素。
在服务的WSDL中，您将找到AddLeads元素的以下内容：
<s:element name="AddLeads">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="username" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="password" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="leads">
<s:complexType mixed="true">
<s:sequence>
<s:any/>
</s:sequence>
</s:complexType>
</s:element>
</s:sequence>
</s:complexType>
</s:element>
这是AddLeads元素的架构。该架构将用于验证您提供的标记。
请注意，username和password具有类型字符串，而leads是“任何”复杂类型。这意味着像这样的消息：
<soapenv:Body>
<AddLeads>
<username>foo</username>
<password>bar</password>
<leads>
You may enter ANY elements at this point
</leads>
</AddLeads>
</soapenv:Body>
但是“任何”复杂类型作为定义都有点宽泛，因此Web服务的创建者决定将其限制为他们认为有用的信息。以下模式限制了AddLeads操作的上下文中的“any”：
http://service.leads360.com/Documentation/Schemas/Client/Leads.Request.xsd
以下是有效的实例：
http://service.leads360.com/Documentation/Examples/Client/AddLeads.leads.xml
我不知道PHP，但您的代码必须生成一个消息，该消息尊重Web服务WSDL类型leads类型。
我建议您使用SoapUI之类的工具来创建调用Web服务的请求。获得成功响应的有效消息内容后，请调整PHP代码以生成相同的格式。您还会发现TCP Monitor（另一个工具）非常有用，可以查看客户端与Web服务之间交换的消息。
