Using the FTP Session Log

See more FTP Examples

The Chilkat FTP component can keep a session log if the KeepSessionLog property is turned on. This is helpful in debugging problems. Chilkat support will usually ask for a session log when working to resolve your problem, because it contains a log of the exact commands sent to the FTP server, and the exact responses received. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final ftp = CkFtp2();

  ftp.hostname = 'ftp.example.com';
  ftp.username = 'login';
  ftp.password = 'password';

  // Set the KeepSessionLog property in order to keep a session log.
  // The session log will continuously grow in memory.  The
  // ClearSessionLog method may be called to clear it.  The session
  // logging may be turned on/off at any point.
  ftp.keepSessionLog = true;

  // Connect and login to the FTP server.
  try {
    ftp.connect();
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Change to the remote directory where the existing file is located.
  try {
    ftp.changeRemoteDir('junk');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // To clear the SessionLog at any point, call ClearSessionLog:
  // call ftp.ClearSessionLog();

  // Append moreHamlet.txt to hamlet.txt on the FTP server.
  final localFilename = 'moreHamlet.txt';
  final remoteFilename = 'hamlet.txt';

  try {
    ftp.appendFile(localFilename, remoteFilename);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  ftp.disconnect();

  // Display the entire session log:
  print(ftp.sessionLog);

  print('File Appended!');
