Question

我的WCF服务遇到了一个奇怪的问题。

我可以提交消息，并返回结果。我所拥有的问题是服务器显示为响应的问题，客户端获得了不同的版本。

无法更改客户端软件以使其正常工作。它基于WSDL合同，这是WCF服务的创建方式。

更新：似乎我们在XML中使用的所有默认NameSpaces都被出站数据上的新默认值覆盖。

服务

 [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
 [WebServiceBindingAttribute(Name = "QUPA_AR101102_Binding", Namespace = "urn:hl7-org:v3")]
GetDemographicsResponse1 IQUPA_AR101102.HCIM_IN_GetDemographics(Message request)
        {
            HCIM.HIALServices.QUPA_AR101102_Service service = new HIALServices.QUPA_AR101102_Service();

            XmlDocument doc = new XmlDocument();
            doc.LoadXml(request.GetReaderAtBodyContents().ReadOuterXml());

            HCIM.HIALMessaging.GetDemographics gd = new HIALMessaging.GetDemographics(System.Web.HttpContext.Current);
            XmlNode gdr = gd.HIALRequest(doc);
        //These 2 lines produce the same data on the server, but the client sees this totally different.
        //HCIM.HL7v3.Objects.QUPA_AR101102.HCIM_IN_GetDemographicsResponse response = this.getMessageObject<HCIM.HL7v3.Objects.QUPA_AR101102.HCIM_IN_GetDemographicsResponse>(gdr.OuterXml, "urn:hl7-org:v3");
        HCIM_IN_GetDemographicsResponse1 r1 = new HCIM_IN_GetDemographicsResponse1(gd.wcfObjectResponse as HCIM.HL7v3.Objects.QUPA_AR101102.HCIM_IN_GetDemographicsResponse);            
       //the above line is a serialized version of the XML - I just packaged it up to` test

        return r1;
    }

合同

[ServiceContract(Namespace = "urn:hl7-org:v3")]
public interface IQUPA_AR101102
{
    [OperationContract(Name = "HCIM_IN_GetDemographics", Action = "urn:hl7-org:v3/QUPA_IN101101")]
    HCIM_IN_GetDemographicsResponse1 HCIM_IN_GetDemographics(Message request);

...
}

（代码只是嘲笑功能，直到我得到正确的响应。）

当我查看服务器上生成的XML或服务器上的对象时。

服务器端的XML样本看起来像这样 - 我可以在HCIM_IN_GetDemograhpics类型中对其进行序列化和反序列化，而不会出现任何问题或降级数据。

来自服务器的XML /数据我期待（没有）

<HCIM_IN_GetDemographicsResponse xmlns="urn:hl7-org:v3">
    <id root="2.16.840.1.113883.3.51.1.1.1" extension="404002d6-3978-413d-a49d-b11e240bbf26" />

    <processingCode code="P" />
    <processingModeCode code="T" />
    <acceptAckCode code="NE" />
    <receiver typeCode="RCV">
...

当我的客户收到这个时，它就会变成完全不同的东西。

Cut-Down WSDL 原始版本为19,000行。具有xsd：anyType的元素指向架构中的具体元素。一个客户端对此进行了修改，因此他们可以在该部分中使用XML。如果我能让这个WCF使用这样的WSDL就足够了。

我尝试更改返回类型，容器类型等。没有任何工作。我试图实现我的WCF服务，只接受并返回XMLNodes，但失败了。

数据正在正确发送，但.NET正在某种程度上改变它，我不确定如何/为什么。

传入消息的默认命名空间是：urn：hl7-org：v3 正在发送的输出使用了错误的命名空间：xmlns：a =＆＃34; http：//schemas.datacontract.org/2004/07/HCIM.HL7v3.Objects.QUPA_AR101102"

我补充说：

[System.Runtime.Serialization.DataContract(Namespace = "urn:hl7-org:v3")]

到HCIM_IN_GetDemograhpicsResponse对象，但现在客户端的结果对于每个属性都是null。

有没有办法让字符串类型作为此WCF服务的输入/输出类型，其中连接设备不需要更改其绑定/代码（它们与WSDL协定绑定）。 / p>

Answer 1

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开关生成注释，而不是将注释添加到生成的文件中。

因此，在生成类时，请使用XMLSerializer而不是DataContract序列化程序：

svcutil QUPA_AR101102.wsdl / serializer：XmlSerializer / fault

Answer 2

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serializer命令： svcutil QUPA_AR101102.wsdl / serializer：XmlSerializer / fault

WCF服务返回＆＃34;坏＆＃34;响应 - 客户端获取的数据与服务器发送的数据不同
