Question

我有IDispatchMessageFormatter实现

    class ServerMessageFormatter : IDispatchMessageFormatter
{
    private IDispatchMessageFormatter Formatter;

    public ServerMessageFormatter(IDispatchMessageFormatter formatter)
    {
        this.Formatter = formatter;
    }

    public void DeserializeRequest(System.ServiceModel.Channels.Message message, object[] parameters)
    {
        Formatter.DeserializeRequest(message, parameters);
    }
}

和OperationBegavior

        public void ApplyDispatchBehavior(OperationDescription operationDescription, DispatchOperation dispatchOperation)
    {
        ServerMessageFormatter Formatter = new ServerMessageFormatter(dispatchOperation.Formatter);
        dispatchOperation.Formatter = Formatter;
    }

并致电肥皂服务

  GetInfoRequest message = CheckedFields;
    string soap = @"<?xml version=""1.0"" encoding=""utf-8""?>
            <soap12:Envelope xmlns:soap12=""http://www.w3.org/2003/05/soap-envelope"">
              <soap12:Header>
                <Action soap12:mustUnderstand=""1"" xmlns=""http://www.w3.org/2005/08/addressing"">ServiceModel/IService/GetSoapData</Action>
              </soap12:Header>
            <soap12:Body>
        <GetInfoRequest  xmlns=""ServiceModel"">
            <Data xmlns:d4p1=""http://schemas.microsoft.com/2003/10/Serialization/Arrays"" xmlns:i=""http://www.w3.org/2001/XMLSchema-instance""/>
        </GetInfoRequest>
        </soap12:Body>
        </soap12:Envelope>";
    XmlSerializer serializer = new XmlSerializer(typeof(GetInfoRequest));
    HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://dev.add.renault.com/Service.svc/soap");
    MemoryStream stream1 = new MemoryStream();
    serializer.Serialize(stream1, message);
    stream1.Position = 0;
    StreamReader sr = new StreamReader(stream1);
    string t = sr.ReadToEnd();
    t = t.Remove(0, 22).Trim();
    t = string.Format(soap, t);
    ASCIIEncoding encoding = new ASCIIEncoding();
    request.Timeout = 99999999;
    request.ContentLength = t.Length;
    request.Method = "POST";
    request.ContentType = "application/soap+xml; charset=utf-8";
    request.Accept = "application/soap+xml; charset=utf-8";

    using (Stream stm = request.GetRequestStream())
    {
        using (StreamWriter stmw = new StreamWriter(stm))
        {
            stmw.Write(t);
        }
    }

    var response = (HttpWebResponse)request.GetResponse();
    var abc = new StreamReader(response.GetResponseStream());

问题是当我调用我的REST服务并在DeserializeRequest中设置断点时，我看到Formatter已经从Operation Behavior设置了值。但是当调用soap服务时，我的Formatter具有null值并且反序列化被中止。为什么在打肥皂时我有这个问题？有什么想法吗？

不幸的是，我不能在操作行为中触发断点并查看dispatchOperation的值...

您没有显示如何配置服务以添加自定义IDispatchMessageFormatter扩展。所以在这里猜一下，你可能只是将它添加到webHttpBinding端点而不是基于soap的绑定端点。如果您使用的是WebHttpBehavior方法（GetRequestDispatchFormatter＆amp; GetReplyDispatchFormatter），那么这将不适用于您的soap端点。这个blog post很好地概述了如何将IDispatchMessageFormatter与webHttpBinding和basicHttpBinding一起使用。

编辑：本文中的特定代码显示了如何将自定义消息格式化程序添加到basicHttpBinding，如下所示。就在该部分之前，他解释了为什么这种方法是必要的。

    //--- snipped ---//

    string baseAddress = "http://" + Environment.MachineName + ":8000/Service";
    ServiceHost host = new ServiceHost(typeof(Service), new Uri(baseAddress));
    ServiceEndpoint endpoint = host.AddServiceEndpoint(typeof(ITest), new BasicHttpBinding(), "");
    endpoint.Contract.Operations.Find("Add").Behaviors.Add(new MyOperationBehaviorAttribute());
    host.Open();

    //--- snipped ---//

调用soap服务时，dispatchOperation.Formatter为NULL
