Question

我需要为非常具体的SOAP布局编写服务合同（端点不在我们的控制之下）。本质上，我需要生成以下soap请求：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Body>
        <auth message-id="1">
            <login>
                <UserName>goLocalTeam</UserName>
                <Password>yeay!</Password>
            </login>
        </auth>
    </soapenv:Body>
</soapenv:Envelope>

我创建了以下合同：

[ServiceContract(Namespace="", SessionMode=SessionMode.NotAllowed)]
public interface IPrototype
{
    [OperationContract(Action="auth")]
    string auth([MessageParameter(Name = "message-id")]int messageId, Login login);
}

[DataContract(Namespace="")]
public class Login 
{
    [DataMember]
    public string userName { get; set; }
    [DataMember]
    public string Password { get; set; }

}

但是，当我构建客户端并调用时，message-id参数将呈现为<auth>内的节点，而不是属性。

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
    <Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">auth</Action>
  </s:Header>
  <s:Body>
    <auth>
      <message-id>0</message-id>
      <login>
        <userName>yay</userName>
        <Password>yoy</Password>
      </login>
    </auth>
  </s:Body>
</s:Envelope>

知道如何让WCF从节点切换到属性的简单类型参数吗？

Answer 1

使用XmlSerializerFormat属性而不是DataContract。

请查看MSDN以确切了解如何使用它，但基本上您使用XmlAttribute和XmlElement标记成员，因此它看起来像：

[ServiceContract(Namespace="", SessionMode=SessionMode.NotAllowed)]
public interface IPrototype
{
    [OperationContract(Action="auth")]
    string Auth(AuthRequest authRequest);
}
[MessageContract(IsWrapped = false)] // notice the unwrapping
public class AuthRequest
{
    [XmlAttribute]
    public int message-id { get; set; }
    [XmlElement]
    public Login Login { get; set; }
}
[MessageContract]
public class Login 
{
    [XmlElement]
    public string userName { get; set; }
    [XmlElement]
    public string Password { get; set; }

}

好的，我解决了它，部分归功于user3906922，使用xml序列化程序格式。我只需要更深入一点并完全构建消息：

[ServiceContract(Namespace="", SessionMode=SessionMode.NotAllowed)]
public interface IPrototype
{
    [OperationContract(Action = "auth")]
    [XmlSerializerFormat]
    authResponse auth(authRequest auth);
}

[MessageContract(IsWrapped = false)]
public class authRequest
{
    [MessageBodyMember]
    public authRequestBody auth { get; set; }
}

[MessageContract(IsWrapped = true, WrapperName = "auth")]
public class authRequestBody 
{
    [XmlAttribute(AttributeName = "message-id"), MessageBodyMember]
    public int messageId { get; set; }

    [MessageBodyMember]
    public Login login { get; set; }
}

[MessageContract]
public class Login 
{
    [MessageBodyMember]
    public string userName { get; set; }

    [MessageBodyMember]
    public string Password { get; set; }

}

强制参数作为服务合同属性
