SFTP Simplified Download

Demonstrates how to SFTP download a file by passing a remote filepath to DownloadFileByName. Ruby

require 'chilkat'

success = false

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

sftp = Chilkat::CkSFtp.new()

# Set some timeouts, in milliseconds:
sftp.put_ConnectTimeoutMs(15000)
sftp.put_IdleTimeoutMs(15000)

# Connect to the SSH server.  
# The standard SSH port = 22
# The hostname may be a hostname or IP address.
hostname = "sftp.example.com"
port = 22
success = sftp.Connect(hostname,port)
if (success != true)
    print sftp.lastErrorText() + "\n";
    exit
end

# 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")
if (success != true)
    print sftp.lastErrorText() + "\n";
    exit
end

# After authenticating, the SFTP subsystem must be initialized:
success = sftp.InitializeSftp()
if (success != true)
    print sftp.lastErrorText() + "\n";
    exit
end

# Download the file:

localFilePath = "c:/temp/hamlet.xml"
# Note: The remote filepath may be an absolute filepath,
# a relative filepath, or simply a filename.  
# Relative filepaths are always relative to the home directory
# of the SFTP/SSH user account.  There is no such thing
# as "current remote directory" in the SFTP protocol. 
# A filename with no path implies that the file is located
# in the SFTP user account's home directory.
remoteFilePath = "subdir1/subdir2/hamlet.xml"
success = sftp.DownloadFileByName(remoteFilePath,localFilePath)
if (success != true)
    print sftp.lastErrorText() + "\n";
    exit
end

print "Success." + "\n";
