从.Net问题中消费轴.Net服务

Question

我对客户端C# web应用程序中的消费轴(JAVA) web服务有问题。我必须使用第三方web服务，与JAVA客户端一起正常工作！当我们用SoapUI测试它时，它工作得很好。我已经添加了web服务和服务引用( asmx和wcf)，但是这两个引用都是一样的！我认为wsdl.exe (reference.cs)生成的代码有问题，因为它不能反序列化服务器支持的响应。我可以在调试模式下看到SOAP响应，并且我知道响应是正确的。但是，在反序列化过程开始时，我们有异常“XML文档格式不好！”、“根名称空间缺失”。

我知道名称空间、名称空间前缀和生成代码都有问题，如果添加WCF引用，就会得到明确的异常消息：

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'.

有什么意见或帮助吗？

谢谢

Answer 1

在我看来，根据XSD / WSDL，响应是无效的。这就是问题所在：

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

此元素不为默认前缀声明命名空间，但：

• WSDL本身将目标命名空间声明为http://www.mytown.com，因此应该使用它。
• http://www.mytown.com的父元素已经使用了默认命名空间。

您需要摆脱这个xmlns=""或使用xmlns="http://www.mytown.com"。尝试使用费德勒来拦截并更改响应，这样您就可以检查它是否真的工作了。

如果是这样的话，要么要求那些Java开发人员修改他们的服务以便返回有效的响应，要么在使用SoapExtension或IClientMessageInspector的情况下实现定制的WCF，并重新格式化消息。
