Python based on sftp and rsa key to realize the remote copy file method

This article example describes Python based on sftp and rsa secret key to realize the remote copy file method. Shared for your reference, as follows:

If a password-free login with RSA secret key is used between two servers, you can first find out the corresponding directory of the rsa secret key (e.g. find / -name id_rsa or locate id_rsa).

The scp function can then be implemented in the paramiko module in Python like this.

def scp_by_key(host_ip, host_port, remote_path, local_path, username, pkey_path):
  try:
    key=.from_private_key_file(pkey_path)
    t = ((host_ip, host_port))
    (username=username, pkey=key)
    sftp = .from_transport(t)
    src = remote_path
    des = local_path
    (src,des)
    ()
  except Exception as e:
    print e

We can use the method like this:

Isn't it cool to use it? But only if you have the rsa key... If you need a password, just pass in the pkey parameter instead of the password.

t = ((host_ip, host_port))
(username=username, password='xxx')
