FTP Sync Upload Tree w/ Must-Match Filename Constraints

See more FTP Examples

Demonstrates how synchronize a directory tree in the upload direction, but only upload files matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

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.something.com';
  ftp.username = 'my_login';
  ftp.password = 'my_password';

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

  // Set the current remote directory to the root of
  // the tree to receive the uploaded files.
  try {
    ftp.changeRemoteDir('/subDir1');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Possible synchronization modes are:
  // mode=0: Upload all files
  // mode=1: Upload all files that do not exist on the FTP server.
  // mode=2: Upload newer or non-existant files.
  // mode=3: Upload only newer files. If a file does not already exist on the FTP server, it is not uploaded.
  // mode=4: transfer missing files or files with size differences.
  // mode=5: same as mode 4, but also newer files. 

  // This example will upload all files, but only those files having filenames
  // that match *.gif and *.eml

  // Imagine our local directory tree has these files and directories:

  // 	accentedLatin1.txt
  // 	accentedUtf8.txt
  // 	alice.key
  // 	anter_cert.pem
  // 	chiliPepper.gif
  // 	helloWorld.pdf
  // 	abc/chiliPepper.gif
  // 	abc/ghk/
  // 	data/chiliPepper.gif
  // 	data/xyz/dkimHtmlBody.txt
  // 	data/xyz/dkimVerifyTest.eml
  // 	data/xyz/emailForCreateDsn.eml
  // 	text/frenchUtf8.txt
  // 	text/helloWorld.txt
  // 	text/PolishEmailBody.txt
  // 	text/something/

  ftp.syncMustMatch = '*.eml; *.gif';
  final mode = 0;
  try {
    ftp.syncRemoteTree('c:/temp/subDir1', mode);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  ftp.disconnect();

  // Show the files downloaded.
  final st = CkStringTable();
  ftp.getSyncedFiles(st);

  final numFiles = st.count;
  var i = 0;
  final remoteFilename = '';
  while (i < numFiles) {
    print(st.stringAt(i));
    i++;
  }

  // Output showing the files uploaded:

  // chiliPepper.gif
  // abc/chiliPepper.gif
  // data/chiliPepper.gif
  // data/xyz/dkimVerifyTest.eml
  // data/xyz/emailForCreateDsn.eml
