Registro de salida usando FtpWebRequest

Question

Me pregunto si es posible tener un registro de salida para mi cliente FTP usando FtpWebRequest .

Algo como esto:

[R] USER xxx
[R] 331 Please specify the password.
[R] PASS (hidden)
[R] 230 Login successful.
[R] SYST
[R] 215 UNIX Type: L8
[R] FEAT
[R] 211-Features:
[R]  EPRT
[R]  EPSV
[R]  MDTM
[R]  PASV
[R]  REST STREAM
[R]  SIZE
[R]  TVFS
[R] 211 End
[R] PWD
[R] 257 "/"
[R] CWD /
[R] 250 Directory successfully changed.
[R] PWD
[R] 257 "/"
[R] TYPE A
[R] 200 Switching to ASCII mode.
[R] PASV
[R] 227 Entering Passive Mode (10,232,201,81,141,175)
[R] Opening data connection IP: 10.232.201.81 PORT: 36271
[R] LIST -al
[R] 150 Here comes the directory listing.
[R] 226 Directory send OK.

Esta salida, por ejemplo, es cuando se conecta ...

Mi código actual solo hace lo siguiente:

// Get the object used to communicate with the server.
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(string.Format("ftp://{0}", addrEndPoint));
request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
request.Credentials = new NetworkCredential(_currentConnection.Username, _currentConnection.Password);

FtpWebResponse response = (FtpWebResponse)request.GetResponse();

Stream responseStream = response.GetResponseStream();
StreamReader readStream = new StreamReader(responseStream, System.Text.Encoding.UTF8);

if (readStream != null)
{
    Console.WriteLine(readStream.ReadToEnd());
}

Puedes hacer esto usando Network Tracing . Para configurarlo , cree (o modifique, si ya tiene) App.config archivo App.config , para que se vea así (si ya tiene el archivo, deberá agregarle la configuración):

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.diagnostics>
    <sources>
      <source name="System.Net" tracemode="protocolonly" maxdatasize="1024">
        <listeners>
          <add name="System.Net"/>
        </listeners>
      </source>
    </sources>
    <switches>
      <add name="System.Net" value="Information"/>
    </switches>
    <sharedListeners>
      <add name="System.Net"
        type="System.Diagnostics.TextWriterTraceListener"
        initializeData="network.log"
      />
    </sharedListeners>
    <trace autoflush="true"/>
  </system.diagnostics>
</configuration>

Si hace esto, su aplicación creará un archivo network.log , que podría verse más o menos así:

System.Net Information: 1 : [8892] FtpWebRequest#2383799::.ctor(ftp://test/)
System.Net Information: 0 : [8892] FtpWebRequest#2383799::GetResponse(Method=LIST.)

System.Net Information: 0 : [8892] FtpWebRequest#2383799::(Releasing FTP connection#33675143.)

Es bastante detallado, pero contiene la información que necesita. Si desea modificar cómo está escrito el archivo de registro, puede implementar su propio TraceListener y usarlo en el archivo de configuración en lugar de TextWriterTraceListener .

Answer 2

revisa estos enlaces para referencia. si tiene IIS 7, entonces es posible implementar su propia funcionalidad.

implementando el método de registro de la interfaz IFtpLogProvider

using System;
using System.IO;
using Microsoft.Web.FtpServer;
using System.Diagnostics;
using System.Diagnostics.Eventing;

namespace FtpLogging
{
    public class FtpLogDemo : BaseProvider,
        IFtpLogProvider
    {
        void IFtpLogProvider.Log(FtpLogEntry loggingParameters)
        {
         .......
