c# - WCF - 反序列化时控制命名空间

Question

外部 (java) 应用程序向我们的网络服务发送消息。此消息包含多个命名空间:

<StUF:Fo01Bericht xmlns:StUF="http://www.egem.nl/StUF/StUF0300">
    <LVO:stuurgegevens xmlns:LVO="http://www.vrom.nl/StUF/sector/lvo/0305">
        <StUF:versieStUF>0300</StUF:versieStUF>
        <StUF:berichtcode>Fo01</StUF:berichtcode>
    </LVO:stuurgegevens>
    <StUF:body>
        <StUF:code>200</StUF:code>
        <StUF:plek>LVO</StUF:plek>
        <StUF:omschrijving>test</StUF:omschrijving>
    </StUF:body>
</StUF:Fo01Bericht>

WCF 服务无法反序列化此消息，因为第二行有 LVO 前缀(根据 WSDL，它应该是 StUF)。

我想让我们的网络服务接受这些消息。有没有办法做到这一点 - 最好使用属性？

我在接受来自第三方的 soap 消息时遇到了这个问题。

这是我发送的 soapHeader(注意 UsernameToken 中的不同命名空间):

<wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wssu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
        <wsse:UsernameToken>
            <wsse:Username>userName</wsse:Username>
            <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">password</wsse:Password>
            <wsse:Nonce>nonce</wsse:Nonce>
            <wssu:Created>2015-02-19T16:24:32Z</wssu:Created>
        </wsse:UsernameToken>
    </wsse:Security>

为了正确反序列化，我需要在我的 DataContract 中实现 IxmlSerializable，如下所示:

[DataContract(Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd", Name = "Security")]
public partial class SecurityHeaderType
{
    [XmlElementAttribute(Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd")]
    [DataMember]
    public UsernameToken UsernameToken { get; set; }
}

public class UsernameToken : IXmlSerializable
{
    public string Username { get; set; }
    public string Password { get; set; }
    public string Nonce { get; set; }
    public string Created { get; set; }

    public XmlSchema GetSchema()
    {
        throw new NotImplementedException();
    }

    public void ReadXml(XmlReader reader)
    {
        Dictionary<string, string> secDictionary;
        string xml = reader.ReadOuterXml();

        using (var s = GenerateStreamFromString(xml))
        {
            secDictionary =
                        XElement.Load(s).Elements()
                        .ToDictionary(e => e.Name.LocalName, e => e.Value);
        }

        Username = secDictionary["Username"];
        Password = secDictionary["Password"];
        Nonce = secDictionary["Nonce"];
        Created = secDictionary["Created"];          

    }

然后我可以反序列化我的标题，如下所示:

if (OperationContext.Current.IncomingMessageHeaders.FindHeader("Security", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd") != -1)
{
   var securityHeader = OperationContext.Current.IncomingMessageHeaders.GetHeader<SecurityHeaderType>("Security", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");
}
