我们有一个带有以下合约的 WCF 设置:
[ServiceContract(
Namespace = Constants.Namespaces.HL7Namespace,
Name = Constants.Roles.ContentRequiredDocumentManagementSystem)]
// XmlSerializerFormat is needed to expose the HL7 schema fields without the "Field" suffix on each one, eg: idField
[XmlSerializerFormat]
public interface ICDARequest
{
[OperationContract(
// wsdl request action
Action = Constants.Namespaces.HL7Namespace + ":" + Constants.Interactions.RCMR_IN000029UV01 + "." + Constants.VersionType.NormativeCode + Constants.Version.InteractionVersion,
// wsdl operation name
Name = Constants.Interactions.RCMR_IN000029UV01,
// wsdl response action
ReplyAction = Constants.Namespaces.HL7Namespace + ":" + Constants.Interactions.RCMR_IN000030UV01 + "." + Constants.VersionType.NormativeCode + Constants.Version.InteractionVersion)]
SearchMessagesResponse SearchMessages(SearchMessagesRequest RCMR_IN000029UV01);
[MessageContract(
IsWrapped = false]
public class SearchMessagesResponse
{
[MessageBodyMember(
Name = State.Constants.Interactions.RCMR_IN000030UV01,
Namespace = State.Constants.Namespaces.HL7Namespace)]
public RCMR_IN000030UV01 data;
}
}
- 这些基于使用
xsd.exe
. - 然后,我们更改架构以使用自定义命名空间添加自定义元素以区分它并重新生成类。
- 这工作得很好。
它补充说:
[System.Xml.Serialization.XmlTypeAttribute(TypeName = "BCCDX.DistributionStatus", Namespace = "urn:bccdx.ca")]
public partial class BCCDXDistributionStatus
{
[System.Xml.Serialization.XmlElementAttribute("receivedTime", Namespace = "urn:bccdx.ca", IsNullable = false)]
public TS receivedTime{...}
}
这是想要的。
然后在 WCF 服务中,我们可以使用新的类和成员:
var distStatus = new BCCDXDistributionStatus();
distStatus.receivedTime = CreateTS(locStat.MessageDownloadDate);
然后将其序列化并通过网络发送,如下所示:
<distributionStatus xmlns="urn:bccdx.ca">
<receivedTime value="201702150956-0800"/>
</distributionStatus>
这几乎是正确的。问题在于 XML 文档没有对"urn:bccdx.ca"
命名空间的引用。我假设它会在序列化时自动添加到文档根元素中,但我错了。这就是最终的样子:
<RCMR_IN000030UV01 ITSVersion="XML_1.0" xmlns="urn:hl7-org:v3">
...
</RCMR_IN000030UV01>
当真正需要的是:
<RCMR_IN000030UV01 ITSVersion="XML_1.0" xmlns="urn:hl7-org:v3" xmlns:x="urn:bccdx.ca">
...
</RCMR_IN000030UV01>
注意带有前缀的 urn:bccdx.ca
我想知道,如果我们可以添加多个命名空间,如何通过合同为生成的序列化消息 XML 添加前缀?我在网上看到了覆盖默认序列化程序的提示,但我宁愿不这样做。以前肯定已经考虑过并处理过这个问题吗?
