如何使用名稱空間前綴反序列化soap請求？

Question

第一個請求起作用。第二個返回arg0中的空值。唯一的區別是命名空間前綴「ns2」。帶有前綴的請求來自外部來源，無法更改。

<?xml version="1.0" ?> 
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"> 
<S:Body><putEvent xmlns="http://xxx.xxx.x.xx/"> 
<arg0>test</arg0> 
</putEvent></S:Body> 
</S:Envelope> 


<?xml version="1.0" ?> 
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"> 
<S:Body><ns2:putEvent xmlns:ns2="http://xxx.xxx.x.xx/"> 
<arg0>test</arg0> 
</ns2:putEvent></S:Body> 
</S:Envelope> 

如何正確處理這樣的請求？現在處理它的代碼是從wsdl生成的。

的WSDL：

Answer 1

我想你說的是WCF服務/客戶端。因此，您必須使用行爲IEndpointBehavior來擴展您的服務/客戶端。你必須認識到IDispatchMessageInspector/IClientMessageInspector這將檢查請求消息，並與所需的命名空間prifix糾正它。 Here是一個很好的解釋。

Answer 2

沒有看到完整的XSD每個導入的模式可能很難說，但我相信這個問題是這樣的：

<S:Body><ns2:putEvent xmlns:ns2="http://xxx.xxx.x.xx/"> 
<arg0>test</arg0> <--- here 
</ns2:putEvent></S:Body> 

的問題是，在沒有工作的第一種情況下，爲arg0也包含在http://xxx.xxx.x.xx中由隱式命名空間包含，而第二個，<putEvent>位於正確的命名空間中，但<arg0>不是。

因此客戶實際上是產生了錯誤的請求，應當發出這樣的：

<S:Body><ns2:putEvent xmlns:ns2="http://xxx.xxx.x.xx/"> 
<ns2:arg0>test</ns2:arg0> <--- here 
</ns2:putEvent></S:Body> 

HTH，
