.net消費iSeries網絡服務

我想用.Net來使用iseries web服務。我已經成功地與iSeries上的其他Web服務進行通信，但在這個特定的服務器上，我遇到了一個很奇怪的問題。.net消費iSeries網絡服務

以下是iSeries Web服務的wsdl。

當我在了SoapUI測試此，這裏是請求/響應我接收：

了SoapUI請求：

<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>

了SoapUI響應：

<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>

迴應正是我期望的。注意我正在取回一個聯繫人，這是正確的。

當我從.net調用的iSeries Web服務這裏是請求/響應我看到在看提琴手時：

淨請求

<?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">

      <ShipToAcct xmlns="">099039</ShipToAcct> 
     </GetContactInfoOperation> 
     </s:Body> 
    </s:Envelope>

淨響應

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"

    <Contacts> 
    </Contacts> 
    </zcn:GetContactInfoOperationResponse> 
    </soapenv:Body> 
</soapenv:Envelope>

在這種情況下，當我從.Net調用它時，我收到一個空節點。沒有聯繫人。

我已經啓用WCF跟蹤，並沒有什麼在.svclog文件伸出。我一直在瘋狂搜索，並發現WSDL中的minOccurs可能存在一些問題。我的想法是，這可能與.NET中的反序列化過程有關。作爲一個便箋和練習，我能夠使用WebClient對象調用SOAP服務，並且使用它中的聯繫人檢索了正確的原始XML。這也導致我認爲反序列化正在發生。

我也嘗試使用wsdl.exe生成代理，但我仍然返回一個空的客戶端節點。

我應該提及的另一件事是，當我在項目中將引用添加到服務引用的iSeries Web服務時，我得到完全相同的結果：沒有聯繫人。

任何幫助，微推，意見，或方向將不勝感激。我已經爲此工作了兩天，但我仍然不完全理解這裏發生的事情。

非常感謝您的幫助。

謝謝。

您是否調試過iSeries的一面，看看它認爲它是作爲請求接收的？聽起來像問題在那裏，而不是在你的要求。 – bvstone 2014-09-22 17:05:55

是的。在iSeries上工作的人已經調試了她的身邊，並且她正在返回一個聯繫人，我可以使用SoapUI看到，但是當我從.Net使用它時不會看到。 – sloaniebaloney 2014-09-22 17:30:45

在iSeries上他們可以看到返回的數據是你期望的，但是實際返回的數據是不同的。 iSeries或者返回一個聯繫人。我會和他們一起坐下來仔細檢查，而不是在任何一方「假設」。 – bvstone 2014-09-22 19:54:38

所以大聲說出來。

事實證明，iSeries開發人員是手解析請求。所以即使從SoapUI和.Net生成的請求在功能上是等效的，結構也是不同的。這在iSeries代碼中沒有正確處理。

我不是iSeries的專家，但我建議我們使用標準xml庫（如果存在的話），以便iSeries正確解析xml請求。

謝謝，寶石指點我在正確的方向。

我已經開發了許多服務，在iSeries中公開和使用數據，我爲此作業嚴重推薦Scott Klement HTTPAPI。試試吧，你不會後悔的。
