(CkPython) SFTP Download to Local Filesystem

Demonstrates how to download a file from an SSH server to the local filesystem. There are no limitations on file size, and the file is streamed directly to the local filesystem.

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

sftp = chilkat.CkSFtp()

# Set some timeouts, in milliseconds:
sftp.put_ConnectTimeoutMs(5000)
sftp.put_IdleTimeoutMs(10000)

# Connect to the SSH server.  
# The standard SSH port = 22
# The hostname may be a hostname or IP address.
hostname = "sftp.example.com"

# Authenticate with the SSH server.  Chilkat SFTP supports
# both password-based authenication as well as public-key
# authentication.  This example uses password authenication.
success = sftp.AuthenticatePw("myLogin","myPassword")

    print(sftp.lastErrorText())

# After authenticating, the SFTP subsystem must be initialized:
success = sftp.InitializeSftp()
if (success != True):
    print(sftp.lastErrorText())

# Open a file on the server:
handle = sftp.openFile("hamlet.xml","readOnly","openExisting")
if (sftp.get_LastMethodSuccess() != True):
    print(sftp.lastErrorText())
    sys.exit()

# Download the file:
