FTP Download File to a Stream

Demonstrates how to FTP download a file to a Chilkat stream. Ruby

require 'chilkat'

success = false

# This example assumes the Chilkat FTP2 API to have been previously unlocked.
# See FTP2 Unlock Sample for sample code.

ftp = Chilkat::CkFtp2.new()

ftp.put_Hostname("my-ftp-server.com")
ftp.put_Port(21)
ftp.put_Username("mFtpLogin")
ftp.put_Password("myFtpPassword")
ftp.put_AuthTls(true)
ftp.put_Passive(true)

# Connect and login to the FTP server using TLS.
success = ftp.Connect()
if (success != true)
    print ftp.lastErrorText() + "\n";
    exit
end

# Move to the sub-directory (from the FTP user's home directory) where the file is located.
success = ftp.ChangeRemoteDir("temp")
if (success == false)
    print ftp.lastErrorText() + "\n";
    exit
end

# Stream to this local file:
streamObj = Chilkat::CkStream.new()
streamObj.put_SinkFile("c:/temp/qa_output/penguins2.jpg")

success = ftp.GetFileToStream("penguins2.jpg",streamObj)
if (success == false)
    print ftp.lastErrorText() + "\n";
    exit
end

ftp.Disconnect()

print "Success." + "\n";
