Чтобы загрузить файл с помощью FTP (протокола передачи файлов), вы можете использовать несколько методов в зависимости от используемого вами языка программирования. Вот несколько примеров на разных языках:

1. Python:

   import ftplib
   def upload_file_ftp(hostname, username, password, file_path, remote_dir):
   try:
       ftp = ftplib.FTP(hostname)
       ftp.login(username, password)
       ftp.cwd(remote_dir)
       with open(file_path, 'rb') as file:
           ftp.storbinary('STOR ' + file_path, file)
       ftp.quit()
       print('File uploaded successfully.')
   except ftplib.all_errors as e:
       print('FTP upload failed:', e)
   # Usage example
   upload_file_ftp('ftp.example.com', 'username', 'password', 'local_file.txt', 'remote_directory')

2. Java:

   import org.apache.commons.net.ftp.FTP;
   import org.apache.commons.net.ftp.FTPClient;
   import java.io.File;
   import java.io.FileInputStream;
   import java.io.IOException;
   public class FTPUploader {
   public static void main(String[] args) {
       String server = "ftp.example.com";
       int port = 21;
       String user = "username";
       String password = "password";
       String localFile = "local_file.txt";
       String remoteDir = "remote_directory";
       FTPClient ftpClient = new FTPClient();
       try {
           ftpClient.connect(server, port);
           ftpClient.login(user, password);
           ftpClient.enterLocalPassiveMode();
           ftpClient.changeWorkingDirectory(remoteDir);
           File file = new File(localFile);
           FileInputStream fis = new FileInputStream(file);
           ftpClient.storeFile(file.getName(), fis);
           fis.close();
           ftpClient.logout();
           System.out.println("File uploaded successfully.");
       } catch (IOException e) {
           e.printStackTrace();
       } finally {
           try {
               if (ftpClient.isConnected()) {
                   ftpClient.disconnect();
               }
           } catch (IOException ex) {
               ex.printStackTrace();
           }
       }
   }
   }

3. PHP:

   <?php
   $server = 'ftp.example.com';
   $username = 'username';
   $password = 'password';
   $file = 'local_file.txt';
   $remoteDir = 'remote_directory';
   $ftpConn = ftp_connect($server);
   $login = ftp_login($ftpConn, $username, $password);
   if ($ftpConn && $login) {
   ftp_pasv($ftpConn, true);
   ftp_chdir($ftpConn, $remoteDir);
   $upload = ftp_put($ftpConn, basename($file), $file, FTP_BINARY);
   if ($upload) {
       echo 'File uploaded successfully.';
   } else {
       echo 'FTP upload failed.';
   }
   ftp_close($ftpConn);
   } else {
   echo 'FTP connection failed.';
   }
   ?>
