从 .Net 使用 AXIS Web 服务问题

Question

我在客户端 C# Web 应用程序中使用 axis (JAVA) Web 服务时遇到问题。我必须使用与 JAVA 客户端正常工作的第三方 Web 服务！当我们用 SoapUI 测试它时，它工作得很好。 我添加了 Web 服务和服务参考（asmx 和 wcf），但两个参考的工作原理相同！我认为我们对 wsdl.exe 生成的代码有问题（reference.cs） 因为它无法反序列化服务器返回的响应。 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。但是当反序列化过程启动时，我们遇到异常“XML 文档格式不正确！”、“根命名空间丢失”

我知道我们在命名空间和命名空间前缀以及生成的代码方面存在问题 如果我们添加 WCF 参考，我们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'.

有任何评论或帮助吗？

谢谢

Answer 1

在我看来，根据 XSD / WSDL，该响应无效。这就是问题所在：

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

该元素没有声明默认前缀的命名空间，但是：

• WSDL 本身将目标命名空间声明为 http://www.mytown。 com 因此它应该使用它
• 默认名称空间已被父元素使用 http://www.mytown.com< /a>

你需要摆脱它xmlns="" 或使用 xmlns="http://www.mytown.com"。尝试使用 Fiddler 拦截响应并更改它，以便您可以检查它真的有效。

如果是这样，请要求这些 Java 开发人员修改他们的服务，以便返回有效响应，或者在 ASMX 情况下实现自定义 SoapExtension 或在 WCF 情况下实现自定义 IClientMessageInspector 并重新格式化消息。
