强制参数作为服务合同属性

Force parameter as Service contract attribute

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>

我创建了以下合约:

[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 参数呈现为 <auth> 中的节点,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 将简单类型参数从节点切换到属性吗?

使用 XmlSerializerFormat 属性而不是 DataContract

看看 MSDN 以了解如何使用它,但基本上你用 XmlAttributeXmlElement 标记成员,所以它看起来像:

[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 序列化器格式。我只需要更深入地构建消息:

[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; }

}
