(Ruby) Co:Z SFTP Binary File Download (from z/OS IBM Mainframe)Demonstrates how to download a binary file, such as a .zip, from a Co:Z SFTP server on a z/OS IBM Mainframe. Note: This example requires Chilkat v11.0.0 or greater.
require 'chilkat' success = false # This example requires the Chilkat API to have been previously unlocked. # See Global Unlock Sample for sample code. sftp = Chilkat::CkSFtp.new() # Connect to the SSH server. hostname = "sftp.example.com" port = 22 success = sftp.Connect(hostname,port) if (success == false) print sftp.lastErrorText() + "\n"; exit end success = sftp.AuthenticatePw("myLogin","myPassword") if (success == false) print sftp.lastErrorText() + "\n"; exit end success = sftp.InitializeSftp() if (success == false) print sftp.lastErrorText() + "\n"; exit end # To download a binary file from the Co:Z SFTP server, # we must switch to binary mode in the following unconventional way. # We pretend to fetch a directory listing for "/+mode=binary" # This has the effect of putting the server in binary mode for transfers. handle = sftp.openDir("/+mode=binary") if (sftp.get_LastMethodSuccess() == false) print sftp.lastErrorText() + "\n"; exit end # Download the "directory listing" (but it's not actually a directory listing, and we'll just discard it.) dirListing = Chilkat::CkSFtpDir.new() success = sftp.ReadDirListing(handle,dirListing) if (success == false) print sftp.lastErrorText() + "\n"; exit end # Close the directory handle: success = sftp.CloseHandle(handle) if (success == false) print sftp.lastErrorText() + "\n"; exit end # Download the binary file: localFilePath = "c:/temp/test.zip" remoteFilePath = "test.zip" success = sftp.DownloadFileByName(remoteFilePath,localFilePath) if (success == false) print sftp.lastErrorText() + "\n"; exit end print "Success." + "\n"; |
