Paramiko getfo

The getfo method in Paramiko library is used to obtain the file-like object associated with an SFTP file transfer.

SFTP (Secure File Transfer Protocol) is a protocol that enables secure file transfers over SSH (Secure Shell) connections.

Syntax

    channel.getfo(remotepath, localfile=None, callback=None)

Parameters

  • remotepath: The path of the remote file to be transferred.
  • localfile (optional): The local file path where the remote file will be saved. If not provided, the file content will be sent to the file-like object obtained from getfo.
  • callback (optional): A callback function that is invoked during the transfer, allowing you to monitor or process the transfer progress. The callback function should accept two parameters: the transferred bytes and the total file size.

Example

Here’s an example that demonstrates the usage of getfo method:

    import paramiko

    # Create an SSH client
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    
    # Connect to the SSH server
    ssh.connect('example.com', username='your_username', password='your_password')
    
    # Open an SFTP session
    sftp = ssh.open_sftp()
    
    # Get the file-like object associated with the remote file
    file_like_object = sftp.getfo('/path/to/remote/file.txt')
    
    # Print the contents of the file-like object
    for line in file_like_object:
        print(line)
    
    # Close the SFTP session
    sftp.close()
    
    # Close the SSH connection
    ssh.close()

In this example, we first create an SSH client and connect to the SSH server using the specified username and password. Then, we open an SFTP session and use the getfo method to obtain the file-like object associated with the remote file at ‘/path/to/remote/file.txt’. We can then iterate over the lines of the file-like object (which represents the content of the remote file) and process them as needed.

After we are done, we close the SFTP session and the SSH connection to clean up resources.

Note that you need to replace ‘example.com’, ‘your_username’, and ‘your_password’ with the appropriate values for your SSH server.
