從.Net中消費AXIS webservice問題

Question

我在客戶端C＃Web應用程序中使用軸（JAVA）Web服務時遇到問題。我必須使用適合JAVA客戶端的第三方Web服務！當我們使用SoapUI進行測試時，它可以很好地工作。 我已經添加了Web服務和服務引用（asmx和wcf），但兩個引用的作用相同！我認爲我們在使用wsdl.exe（reference.cs）生成的代碼時遇到問題 因爲它無法反序列化從服務器支持的響應。 我可以在調試模式下看到SOAP Response，並且我知道響應是正確的。但是，我們有例外「XML文檔格式不正確！」，「根命名空間缺失」時，反序列化進程開始

響應：

<?xml version="1.0" encoding="UTF-8"?> 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
        xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
    <soapenv:Body> 
    <processRequestResponse xmlns="http://www.mytown.com"> 
     <ETIResponse xmlns=""> 
     <ns1:TransactionID xmlns:ns1="http://www.mytown.com">CDK11341818404883</ns1:TransactionID> 
     <ns2:OrigResponseMessage xmlns:ns2="http://www.mytown.com">.....</ns2:OrigResponseMessage> 
     <ns3:CommandStatus xmlns:ns3="http://www.mytown.com">INVALID</ns3:CommandStatus> 
     <ns4:ResultCode xmlns:ns4="http://www.mytown.com">21</ns4:ResultCode> 
     </ETIResponse> 
    </processRequestResponse> 
    </soapenv:Body> 
</soapenv:Envelope>

我知道我們有一個命名空間和命名空間前綴和生成的代碼 問題，如果我們增加WCF參考我們獲得清晰異常消息：

There was an error in serializing body of message : 'There was an error generating the XML document.'. Please see InnerException for more details. 
The prefix '' is bound to the namespace '' and cannot be changed to 'http://www.mytown.com'. 

任何意見或幫助？

感謝

Answer 1

在我看來，響應根據XSD/WSDL無效。這就是問題所在：

<ETIResponse xmlns="">...</ETIResponse> 

此元素聲明沒有命名空間的默認前綴，但是：

• WSDL本身聲明目標命名空間http://www.mytown.com所以它應該使用它
• 默認命名空間已經由父元素與http://www.mytown.com

您需要擺脫那xmlns=""或使用xmlns="http://www.mytown.com"。嘗試使用Fiddler來攔截響應並對其進行更改，以便檢查它是否真的有效。

如果確實如此，無論是問這些Java開發人員，因此返回有效響應修改其服務或WCF的情況下實現ASMX或IClientMessageInspector的情況下定製SoapExtension並重新格式化消息。
