WCF 服务返回 "bad" 响应 - 客户端获取的数据与服务器发送的数据不同
WCF Service returning "bad" response - Client gets data different than what the server sent
我的 WCF 服务遇到了一个奇怪的问题。
我可以提交消息，return 结果。我遇到的问题是服务器显示的响应，客户端得到不同的版本。
无法更改客户端软件以使其正常工作。它基于 WSDL 合同，这是创建 WCF 服务的基础。
更新：
似乎我们在 XML 中使用的所有默认名称空间都被出站数据上的新默认名称空间覆盖。

当我查看在服务器上生成的 XML 或驻留在服务器上的对象时。
服务器端 XML 的示例如下所示 - 我可以将其序列化和反序列化为 HCIM_IN_GetDemograhpics 类型，而不会出现任何问题或数据降级。

我已经尝试更改 return 类型、容器类型等。没有任何效果。我试图实现我的 WCF 服务以仅接受和 return XML 节点，但失败了。
数据正在正确发送，但 .NET 正在以某种方式更改它，我不确定 how/why。
传入消息的默认命名空间是：urn:hl7-org:v3
发送的输出使用了错误的命名空间：xmlns:a="http://schemas.datacontract.org/2004/07/HCIM.HL7v3.Objects.QUPA_AR101102"
我补充了：
[System.Runtime.Serialization.DataContract(Namespace = "urn:hl7-org:v3")]
到 HCIM_IN_GetDemograhpicsResponse 对象，但现在客户端中的每个属性的结果都为 null。
有没有办法将字符串类型作为此 WCF 服务的 input/output 类型，其中连接设备不需要更改其 binding/code（它们绑定到 WSDL 合同） .
这个 Stack Overflow 问题回答了这个问题：
.NET WCF serialization issues
从 WCF 的 WSDL (SOAP) 生成时，我需要使用序列化程序命令：
svcutil QUPA_AR101102.wsdl /serializer:XmlSerializer /fault
WCF .NET 默认使用 DataContractSerializer。您可以通过添加 [XmlSerializerFormat()] 注释来覆盖它。
您可以使用 /serializer:XmlSerializer 开关生成，而不是将注释添加到生成的文件中。
因此在生成 类 时执行此操作以使用 XMLSerializer 而不是 DataContract 序列化程序：
