python ftp upload

To upload a file to an FTP server using Python, you can use the built-in ftplib library. Below is an example of how to upload a file to an FTP server.

Code Example for FTP Upload

from ftplib import FTP

def upload_file(ftp_host, ftp_user, ftp_password, file_path, remote_path):
    try:
        # Connect to the FTP server
        ftp = FTP(ftp_host)
        ftp.login(user=ftp_user, passwd=ftp_password)
        print(f"Connected to {ftp_host}")

        # Open the file in binary mode
        with open(file_path, 'rb') as f:
            # Upload the file to the specified path on the FTP server
            ftp.storbinary(f'STOR {remote_path}', f)
            print(f"Successfully uploaded {file_path} to {remote_path}")

        # Close the connection
        ftp.quit()
    except Exception as e:
        print(f"Error: {e}")

# Example usage
ftp_host = 'ftp.example.com'
ftp_user = 'your_username'
ftp_password = 'your_password'
file_path = 'local_file.txt'  # Path to the local file you want to upload
remote_path = 'remote_directory/remote_file.txt'  # Path on the server

upload_file(ftp_host, ftp_user, ftp_password, file_path, remote_path)

Explanation

1. Importing the library:
   We import the FTP class from ftplib to handle the FTP connection.

2. Connecting to the FTP server:
   We use ftp.login() to log in using the provided credentials.

3. Uploading the file:

   • We open the file in binary mode ('rb').
   • We use the ftp.storbinary() method to upload the file. The first parameter is the FTP command ('STOR'), followed by the remote path where the file will be uploaded.
   • The second parameter is the file object to upload.

4. Handling exceptions:
   We wrap the code in a try...except block to catch any connection or file transfer errors.

5. Closing the connection:
   After the transfer is complete, the FTP connection is closed using ftp.quit().

Notes:

• Make sure the paths are correct: Ensure both file_path and remote_path are valid.
• Firewall and permissions: Ensure the FTP server allows uploads and that you have the necessary permissions.
• FTP in passive mode: If you encounter connection issues, you can switch to passive mode using ftp.set_pasv(True). This might be necessary if the server is behind a firewall.

This code will help you upload files via FTP easily using Python. If your server supports SFTP (secure FTP), you'll need to use a different library, such as paramiko. Let me know if you need help with that!
