extension de savon pour enregistrer mes webservices

Question

J'ai cette extension de savon afin de tracer mes webservices:

using System; 
using System.IO; 
using System.Web.Services.Protocols; 

namespace MyLibrary.MySystem 
{ 
    // Define a SOAP Extension that traces the SOAP request and SOAP 
    // response for the XML Web service method the SOAP extension is 
    // applied to. 

    public class WebServicesTraceExtension : SoapExtension 
    { 
     Stream oldStream; 
     Stream newStream; 
     string filename; 

     // Save the Stream representing the SOAP request or SOAP response into 
     // a local memory buffer. 
     public override Stream ChainStream(Stream stream) 
     { 
      oldStream = stream; 
      newStream = new MemoryStream(); 
      return newStream; 
     } 

     // When the SOAP extension is accessed for the first time, the XML Web 
     // service method it is applied to is accessed to store the file 
     // name passed in, using the corresponding SoapExtensionAttribute. 
     public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute) 
     { 
      return ((TraceExtensionAttribute)attribute).Filename; 
     } 

     // The SOAP extension was configured to run using a configuration file 
     // instead of an attribute applied to a specific XML Web service 
     // method. 
     public override object GetInitializer(Type WebServiceType) 
     { 
      // Return a file name to log the trace information to, based on the 
      // type. 
      return "C:\\" + WebServiceType.FullName + ".log"; 
     } 

     // Receive the file name stored by GetInitializer and store it in a 
     // member variable for this specific instance. 
     public override void Initialize(object initializer) 
     { 
      filename = (string)initializer; 
     } 

     // If the SoapMessageStage is such that the SoapRequest or 
     // SoapResponse is still in the SOAP format to be sent or received, 
     // save it out to a file. 
     public override void ProcessMessage(SoapMessage message) 
     { 
      switch (message.Stage) 
      { 
       case SoapMessageStage.BeforeSerialize: 
        break; 
       case SoapMessageStage.AfterSerialize: 
        WriteOutput(message); 
        break; 
       case SoapMessageStage.BeforeDeserialize: 
        WriteInput(message); 
        break; 
       case SoapMessageStage.AfterDeserialize: 
        break; 
       default: 
        throw new Exception("invalid stage"); 
      } 
     } 

     public void WriteOutput(SoapMessage message) 
     { 
      newStream.Position = 0; 
      FileStream fs = new FileStream(filename, FileMode.Append, 
              FileAccess.Write); 
      StreamWriter w = new StreamWriter(fs); 

      string soapString = (message is SoapServerMessage) ? "SoapResponse" : "SoapRequest"; 
      w.WriteLine("-----" + soapString + " at " + DateTime.Now); 
      w.Flush(); 
      Copy(newStream, fs); 
      w.Close(); 
      newStream.Position = 0; 
      Copy(newStream, oldStream); 
     } 

     public void WriteInput(SoapMessage message) 
     { 
      Copy(oldStream, newStream); 
      FileStream fs = new FileStream(filename, FileMode.Append, 
              FileAccess.Write); 
      StreamWriter w = new StreamWriter(fs); 

      string soapString = (message is SoapServerMessage) ? 
           "SoapRequest" : "SoapResponse"; 
      w.WriteLine("-----" + soapString + 
         " at " + DateTime.Now); 
      w.Flush(); 
      newStream.Position = 0; 
      Copy(newStream, fs); 
      w.Close(); 
      newStream.Position = 0; 
     } 

     void Copy(Stream from, Stream to) 
     { 
      TextReader reader = new StreamReader(from); 
      TextWriter writer = new StreamWriter(to); 
      writer.WriteLine(reader.ReadToEnd()); 
      writer.Flush(); 
     } 
    } 

    // Create a SoapExtensionAttribute for the SOAP Extension that can be 
    // applied to an XML Web service method. 
    [AttributeUsage(AttributeTargets.Method)] 
    public class TraceExtensionAttribute : SoapExtensionAttribute 
    { 

     private string filename = "c:\\log.txt"; 
     private int priority; 

     public override Type ExtensionType 
     { 
      get { return typeof(WebServicesTraceExtension); } 
     } 

     public override int Priority 
     { 
      get { return priority; } 
      set { priority = value; } 
     } 

     public string Filename 
     { 
      get 
      { 
       return filename; 
      } 
      set 
      { 
       filename = value; 
      } 
     } 
    } 
} 

dans mon web.config:

<webServices> 
     <soapExtensionTypes> 
     <add type="MyLibrary.MySystem.WebServicesTraceExtension, MyLibrary.MySystem" 
      priority="1" group="0" /> 
     </soapExtensionTypes> 
    </webServices> 

Lorsque j'exécute le service Web et de mettre une pause point sur l'extension du savon - rien ne se passe. J'utilise webservices avec json et non avec xml. Comment puis-je faire fonctionner cette extension de savon?

Answer 1

Vous ne pouvez pas utiliser SoapExtension pour ScriptService (je suppose que vous utilisez le service de script pour renvoyer JSON). SoapExtension par le nom est seulement pour le traitement SOAP. Utilisez le code personnalisé IHttpModule à la place.

Edit:

En fait, votre question is duplicate.
