Using the FTP Session Log

See more FTP Examples

The Chilkat FTP component can keep a session log if the KeepSessionLog property is turned on. This is helpful in debugging problems. Chilkat support will usually ask for a session log when working to resolve your problem, because it contains a log of the exact commands sent to the FTP server, and the exact responses received. Lua

local chilkat = require("chilkat")

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

local ftp = chilkat.Ftp2.new()

ftp.hostname = "ftp.example.com"
ftp.username = "login"
ftp.password = "password"

-- Set the KeepSessionLog property in order to keep a session log.
-- The session log will continuously grow in memory.  The
-- ClearSessionLog method may be called to clear it.  The session
-- logging may be turned on/off at any point.
ftp.keep_session_log = true

-- Connect and login to the FTP server.
local success = ftp:connect()
if not success then
    print(ftp.last_error_text)
    return
end

-- Change to the remote directory where the existing file is located.
success = ftp:change_remote_dir("junk")
if not success then
    print(ftp.last_error_text)
    return
end

-- To clear the SessionLog at any point, call ClearSessionLog:
-- call ftp.ClearSessionLog();

-- Append moreHamlet.txt to hamlet.txt on the FTP server.
local localFilename = "moreHamlet.txt"
local remoteFilename = "hamlet.txt"

success = ftp:append_file(localFilename, remoteFilename)
if not success then
    print(ftp.last_error_text)
    return
end

success = ftp:disconnect()

-- Display the entire session log:
print(ftp.session_log)

print("File Appended!")
