wcf - WCF 4.0 无法从 Java Web 服务反序列化 SOAP

Question

我正在使用 WCF .Net 4.0 来调用用 Java 编写的 Web 服务。WSDL 的一部分引用了 SPML 2.0，我附上了一些代码来描述发生了什么。

对一些 XSD 的 WSDL 引用，我正在使用的部分是

<?xml version="1.0" encoding="utf-8"?>
<xsd:schema xmlns:spml="urn:oasis:names:tc:SPML:2:0" xmlns:sec="urn:corp:iam:spml2:security" xmlns="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" targetNamespace="urn:corp:iam:spml2:security" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:import schemaLocation="../oasis-spml-xsds/pstc_spmlv2_core.xsd" namespace="urn:oasis:names:tc:SPML:2:0" />
  <xsd:complexType name="SuggestUserIDResponseType">
    <xsd:complexContent mixed="false">
      <xsd:extension base="spml:ResponseType">
        <xsd:sequence>
          <xsd:element minOccurs="1" maxOccurs="5" name="uid" type="xsd:string" />
        </xsd:sequence>
      </xsd:extension>
    </xsd:complexContent>
  </xsd:complexType>
</xsd:schema>

和

<?xml version="1.0" encoding="utf-8"?>
<xsd:schema xmlns:spml="urn:oasis:names:tc:SPML:2:0" xmlns="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" targetNamespace="urn:oasis:names:tc:SPML:2:0" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:complexType name="ExtensibleType">
    <xsd:sequence>
      <xsd:any minOccurs="0" maxOccurs="unbounded" namespace="##other" processContents="lax" />
    </xsd:sequence>
    <xsd:anyAttribute namespace="##other" processContents="lax" />
  </xsd:complexType>
  <xsd:complexType name="ResponseType">
    <xsd:complexContent mixed="false">
      <xsd:extension base="spml:ExtensibleType">
        <xsd:sequence>
          <xsd:element minOccurs="0" maxOccurs="unbounded" name="errorMessage" type="xsd:string" />
        </xsd:sequence>
        <xsd:attribute name="status" type="spml:StatusCodeType" use="required" />
        <xsd:attribute name="requestID" type="xsd:ID" use="optional" />
        <xsd:attribute name="error" type="spml:ErrorCode" use="optional" />
      </xsd:extension>
    </xsd:complexContent>
  </xsd:complexType>
</xsd:schema>

所以 WCF 服务引用生成的代理类是

在其中一个服务调用中，返回的 SOAP 消息是

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <ns3:suggestUserIDResponse status="success" requestID="MyApp" xmlns="urn:oasis:names:tc:SPML:2:0" xmlns:ns2="urn:oasis:names:tc:SPML:2:0:password" xmlns:ns3="urn:corp:iam:spml2:security" xmlns:ns4="urn:oasis:names:tc:SPML:2:0:suspend" xmlns:ns5="urn:oasis:names:tc:SPML:2:0:search" xmlns:ns6="urn:oasis:names:tc:SPML:2:0:DSML" xmlns:ns7="urn:oasis:names:tc:DSML:2:0:core" xmlns:ns8="urn:oasis:names:tc:SPML:2:0:batch">
         <ns3:uid>text1</ns3:uid>
         <ns3:uid>text2</ns3:uid>
         <ns3:uid>text3</ns3:uid>
      </ns3:suggestUserIDResponse>
   </soap:Body>
</soap:Envelope>

那时 SOAP 没有SuggestUserIDResponseType正确反序列化为类，SuggestUserIDResponseType.uid始终为空，但重复的 uid 仅SuggestUserIDResponseType.Any作为XmlElement数据类型出现。

有什么建议吗？

Answer 1

我刚刚遇到了同样的问题。看起来问题与用public System.Xml.XmlElement[] Any属性修饰的XmlAnyElementAttribute属性与Order限定符集的组合有关。也可能仅在从具有XmlElement[] Any数组的基类继承时才会发生。

在我的情况下，解决方案是在所有继承的类XmlElementAttribute中删除attibutes、XmlAnyElementAttributeattributes 和MessageBodyMemberAttributeattributes中的 Order 限定符。

注意：粗斜体字很重要，否则你会得到类似的错误：

“ABC_Type”中声明的类型成员“XYZ”缺少必需的“订单”属性。如果类层次结构中的一个类使用显式排序特性（Order），那么它的基类和所有派生类都必须这样做

我还没有进行研究以检查可能产生的副作用 - 一件重要的事情大概是让你的属性在你的类中以正确的顺序排列，以便序列化以正确的顺序发生。

希望这可以帮助某人。
