我正在尝试使用.Net来使用iseries Web服务。我已经成功地与iSeries上的其他Web服务进行通信，但是对于这个特定的服务，我有一个非常奇怪的问题。
以下是来自iSeries的Web服务的wsdl。

当我在SoapUI中测试时，这是我收到的请求/响应：
SoapUI请求：
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:zcn="http://example.com/ZCntInfFr/">
<soapenv:Header/>
<soapenv:Body>
<zcn:GetContactInfoOperation>
<ShipToAcct>099039</ShipToAcct>
</zcn:GetContactInfoOperation>
</soapenv:Body>
</soapenv:Envelope>
SoapUI响应：
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:zcn="http://example.com/ZCntInfFr/">
<soapenv:Header/>
<soapenv:Body>
<zcn:GetContactInfoOperationResponse>
<Contacts>
<ContactData>
<ContactType>ADMIN</ContactType>
<ContactTypeDesc>Administrator</ContactTypeDesc>
<ContactName>Name</ContactName>
<ContactTitle/>
<ContactEmail>Email</ContactEmail>
<ContactPhone/>
<ContactExtension/>
<ContactFax/>
</ContactData>
</Contacts>
</zcn:GetContactInfoOperationResponse>
</soapenv:Body>
</soapenv:Envelope>
响应正是我所期待的。请注意我正在找回一个联系人，这是正确的。
当我从.Net调用iSeries Web服务时，这是我在看Fiddler时看到的请求/响应：
.Net请求
<?xml version="1.0" encoding="iso-8859-1"?><s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<GetContactInfoOperation xmlns="http://www.mysitye.com/ZCntInfFr/">
<ShipToAcct xmlns="">099039</ShipToAcct>
</GetContactInfoOperation>
</s:Body>
</s:Envelope>
.Net回复
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:zcn="http://example.com/ZCntInfFr/">
<soapenv:Header/>
<soapenv:Body>
<zcn:GetContactInfoOperationResponse>
<Contacts>
</Contacts>
</zcn:GetContactInfoOperationResponse>
</soapenv:Body>
</soapenv:Envelope>
在这种情况下，当我从.Net调用它时，我收到一个空节点。没有联系人。

我已经启用了WCF跟踪，并且在.svclog文件中没有任何内容。我一直在疯狂搜索，并且已经看到在WSDL中可能存在一些与minOccurs有关的问题。我的想法是，它可能与.Net中的反序列化过程有关。
作为附注和练习，我能够使用WebClient对象调用SOAP服务，并使用其中的联系人检索正确的原始XML。这也让我想到了反序列化正在发生的事情。
我还尝试使用wsdl.exe生成代理，但我仍然返回一个空的客户端节点。
我应该提到的另一件事是，当我在项目中将对iSeries Web服务的引用添加到服务引用时，我得到完全相同的结果：没有联系人。
任何帮助，推动，建议或指示都将不胜感激。我已经在这方面工作了两天，我仍然没有完全理解这里发生了什么。
非常感谢您的帮助。
感谢。
答案 0 :(得分：1)
所以对bvstone大喊大叫。
事实证明，iSeries开发人员正在手动解析请求。因此，尽管SoapUI和.Net的请求生成功能相同，但结构却不同。在iSeries代码中无法正确处理。
我不是iSeries的专家，但我建议我们使用标准的xml库，如果它们存在，iSeries正确地解析xml请求。
谢谢，bvstone指出我正确的方向。
答案 1 :(得分：0)
我开发了许多在iSeries中公开和使用数据的服务，我认真推荐Scott Klement HTTPAPI来完成这项工作。试一试，你不会后悔。
