我正在尝试使用带有.NET客户端的Axis Web服务，但我在设置WSE配置时遇到了一些问题。我知道WSE 3.0是一种过时的技术，但我坚持使用VS2005和.NET 2.0环境，因此我将不得不使用它。
目前我已经创建了一个新的ASP.NET网站应用程序并在其上启用了WSE。它产生了一系列的部分，比如它的WS：Addressing和WS：Timestamp部分服务器无法处理，我希望将它们删除。我找不到配置设置，所以在搜索SO之后，我开始使用SoapExtensions拦截消息并手动删除部分。
目前我的问题似乎是SoapExtensions中的代码根本没有被执行。这是我的web.config -
<configuration>
<configSections>

我的网络服务方法 -
[WebMethod]
[TestApplication.TraceExtensionAttribute]
public void SendTestMessage()
{
WebSvc.B2BSecureServiceServiceWse svcClient = new WebSvc.B2BSecureServiceServiceWse();
svcClient.SetPolicy("Policy1");
WebSvc.B2BRequest request = new WebSvc.B2BRequest();
WebSvc.B2BRequestHeader WebSvc= new WebSvc.B2BRequestHeader();
// Set Request header properties
request.header = requestHeader;
request.msgPayload = ""; // Text removed
try
{
WebSvc.Response response = svcClient.processRequest(request);
}
catch (Exception ex)
{
}
}
这是我的SoapExtension类 -
public class Snoop : 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;
}
}
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(Snoop); }
}
public override int Priority
{
get { return priority; }
set { priority = value; }
}
public string Filename
{
get
{
return filename;
}
set
{
filename = value;
}
}
}
我猜我在尝试将SoapExtension分配给该方法调用时做错了，所以非常感谢任何帮助！

对于遇到此问题的任何人来说，这就是我使用SoapFilters解决它的方法。以下是来自MSDN的过程 - http://msdn.microsoft.com/en-us/library/aa528788.aspx
