如何反序列化带有命名空间前缀的soap请求？

Question

第一个请求有效。第二个在 arg0 中返回一个空值。唯一的区别是命名空间前缀“ns2”。带前缀的请求来自外部，无法更改。

<?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>

如何正确处理这样的请求？目前处理它的代码是从 wsdl 生成的。

Answer 1

我想你在谈论 WCF 服务/客户端。因此，您必须使用 IEndpointBehavior 行为扩展您的服务/客户端。您必须意识到 IDispatchMessageInspector/IClientMessageInspector 将检查请求消息并使用所需的命名空间前缀进行更正。 Here 是一个很好的解释。

Answer 2

如果没有看到每个导入架构的完整 XSD，可能很难说，但我认为问题在于：

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

问题在于，在第一种情况下，arg0 也通过隐式命名空间包含在http://xxx.xxx.x.xx 中，而在第二种情况下， 在正确的命名空间中，但 不是.

所以客户端实际上是在生成错误的请求，它应该发出这个：

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

HTH，
