FTP

The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files between a client and server on a computer network. FTP is built on a client-server model architecture using separate control and data connections between the client and the server.

The Naas Drivers library offers a suite of methods to connect to an FTP server, retrieve (get) and send (put) files, and list the contents of directories on the server.

Connecting to an FTP Server​

Before any other operation, you must first establish a connection to an FTP server.

user = "my user"
passwd = "my passwd"
ftp = naas_drivers.ftp.connect(user, passwd)

Connecting to an FTPS Server​

FTPS (FTP Secure) is an extension to the commonly used File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) and the Secure Sockets Layer (SSL) cryptographic protocols.

user = "my user"
passwd = "my passwd"
ftp = naas_drivers.ftp.connect(user, passwd, port=990, secure=True)

Force FTPS Protocol​

You can also enforce the secure protocol on all commands.

user = "my user"
passwd = "my passwd"
ftp = naas_drivers.ftp.connect(user, passwd, secure=True, force_prot=True)

Retrieving a File from the Server​

To get a file from the server, specify the path to the file on the server.

path = "/path/to/file/in/ftp"
user = "my user"
passwd = "my passwd"
ftp = naas_drivers.ftp.connect(user, passwd)
ftp.get(path)

Sending a File to the Server​

To send a file to the server, specify the local path to the file and the destination path on the server.

path = "/path/to/local/file"
dest_path = "/path/to/file/in/ftp"
user = "my user"
passwd = "my passwd"
ftp = naas_drivers.ftp.connect(user, passwd)
ftp.send(path, dest_path)

Listing Files in a Directory​

To list the contents of a directory on the server, use the list_directory method.

user = "my user"
passwd = "my passwd"
ftp = naas_drivers.ftp.connect(user, passwd)
ftp.list_directory()

FTP and FTPS protocols, despite being somewhat old, are still widely used for file transfer tasks, especially in enterprise contexts. The Naas Drivers library provides a simple and effective way to use these protocols within your Python environment.
