SFTP Simplified Upload

See more SFTP Examples

Demonstrates how to upload a file to an SSH server in the simplest way -- by calling UploadFileByName and passing remote and local filepaths. Dart

import 'package:chilkat/chilkat.dart';

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

  final sftp = CkSFtp();

  // Set some timeouts, in milliseconds:
  sftp.connectTimeoutMs = 15000;
  sftp.idleTimeoutMs = 15000;

  // Connect to the SSH server.  
  // The standard SSH port = 22
  // The hostname may be a hostname or IP address.
  final hostname = 'sftp.example.com';
  final port = 22;
  try {
    sftp.connect(hostname, port);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Authenticate with the SSH server.  Chilkat SFTP supports
  // both password-based authenication as well as public-key
  // authentication.  This example uses password authenication.
  try {
    sftp.authenticatePw('myLogin', 'myPassword');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // After authenticating, the SFTP subsystem must be initialized:
  try {
    sftp.initializeSftp();
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Upload from the local file to the SSH server.
  // Important -- the remote filepath is the 1st argument,
  // the local filepath is the 2nd argument;
  final remoteFilePath = 'hamlet.xml';
  final localFilePath = 'c:/temp/hamlet.xml';

  try {
    sftp.uploadFileByName(remoteFilePath, localFilePath);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('Success.');
