我有一个SoapExtension,旨在记录所有SOAP请求和响应。对于使用MS Soap Toolkit(OnBase工作流)的应用程序进行的调用,它工作得很好。但是它不适用于$ .ajax()在html页面上进行的调用。这是一个例子:
$.ajax({
type: "POST",
url: url,
data: data,
contentType: "application/json; charset=utf-8",
dataType: "json"
});
它正在调用标记有WebService和ScriptService属性的ASP.NET 3.5 WebService:
[WebService(Namespace = XmlSerializationService.DefaultNamespace)]
[ScriptService]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class DepartmentAssigneeService : WebService
{
private readonly DepartmentAssigneeController _controller = new DepartmentAssigneeController();
/// <summary>
/// Fetches the role items.
/// </summary>
/// <returns></returns>
[WebMethod]
[SoapLog]
public ListItem[] FetchDepartmentItems()
{
return CreateListItems(_controller.FetchDepartments());
}
}
以下是SoapExtension和SoapExtensionAttribute的基础知识:
public class LoggingSoapExtension : SoapExtension, IDisposable { /*...*/ }
[AttributeUsage(AttributeTargets.Method)]
public sealed class SoapLogAttribute : SoapExtensionAttribute { /*...*/ }
我是否缺少允许LoggingSoapExtension在$ .ajax()请求上执行的内容?

这就回答了为什么SoapExtension无法正常工作。有关使用ScriptService进行跟踪的任何建议?唯一想到的是ScriptService基类,该基类提供了记录请求的方法。但是然后我必须在每个ScriptService WebService的每个WebMethod中调用该方法(我有很多方法)。如果可能的话,我想使用和SoapExtension属性一样简洁明了的东西。
最佳答案
我找到了解决方案。通过使用IHttpModule,我可以记录来自任何内容(SOAP,JSON,表单等)的请求。在下面的实现中,我选择记录所有.asmx和.ashx请求。这将替换问题中的LoggingSoapExtension。
public class ServiceLogModule : IHttpModule
{
private HttpApplication _application;
private bool _isWebService;
private int _requestId;
private string _actionUrl;
#region IHttpModule Members
public void Dispose()
{
}
public void Init(HttpApplication context)
{
_application = context;
_application.BeginRequest += ContextBeginRequest;
_application.PreRequestHandlerExecute += ContextPreRequestHandlerExecute;
_application.PreSendRequestContent += ContextPreSendRequestContent;
}
#endregion
private void ContextPreRequestHandlerExecute(object sender, EventArgs e)
{
_application.Response.Filter = new CapturedStream(_application.Response.Filter,
_application.Response.ContentEncoding);
}
private void ContextBeginRequest(object sender, EventArgs e)
{
string ext = VirtualPathUtility.GetExtension(_application.Request.FilePath).ToLower();
_isWebService = ext == ".asmx" || ext == ".ashx";
if (_isWebService)
{
ITraceLog traceLog = TraceLogFactory.Create();
_actionUrl = _application.Request.Url.PathAndQuery;
StreamReader reader = new StreamReader(_application.Request.InputStream);
string message = reader.ReadToEnd();
_application.Request.InputStream.Position = 0;
_requestId = traceLog.LogRequest(_actionUrl, message);
}
}
private void ContextPreSendRequestContent(object sender, EventArgs e)
{
if (_isWebService)
{
CapturedStream stream = _application.Response.Filter as CapturedStream;
if (stream != null)
{
ITraceLog traceLog = TraceLogFactory.Create();
traceLog.LogResponse(_actionUrl, stream.StreamContent, _requestId);
}
}
}
}
我从Capturing HTML generated from ASP.NET借了很多钱。
