Append a Local File to a Remote FTP File

See more FTP Examples

Demonstrates the Chilkat Ftp2.AppendFile method, which appends the contents of a local file to a remote file. The first argument is the local file path and the second is the remote file path. It uses the FTP APPE command.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

import sys
import chilkat

success = False

#  Demonstrates the Ftp2.AppendFile method, which appends the contents of a local file to a remote
#  file.  The 1st argument is the local file path and the 2nd is the remote file path.

ftp = chilkat.CkFtp2()

ftp.put_Hostname("ftp.example.com")
ftp.put_Username("myFtpLogin")

#  Normally you would not hard-code the password in source.  You should instead obtain it
#  from an interactive prompt, environment variable, or a secrets vault.
ftp.put_Password("myPassword")

success = ftp.Connect()
if (success == False):
    print(ftp.lastErrorText())
    sys.exit()

#  Uses the FTP APPE command.  On a server with normal APPE behavior, a missing remote file is
#  created; otherwise the local bytes are appended to the end of the existing remote file.
success = ftp.AppendFile("qa_data/today.log","logs/app.log")
if (success == False):
    print(ftp.lastErrorText())
    sys.exit()

print("Appended to the remote file.")

success = ftp.Disconnect()

    print(ftp.lastErrorText())
