(JavaScript) Using the FTP Session Log

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.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var ftp = new CkFtp2();

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.KeepSessionLog = true;

// Connect and login to the FTP server.
success = ftp.Connect();
if (success !== true) {
    console.log(ftp.LastErrorText);
    return;
}

// Change to the remote directory where the existing file is located.
success = ftp.ChangeRemoteDir("junk");
if (success !== true) {
    console.log(ftp.LastErrorText);
    return;
}

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

// Append moreHamlet.txt to hamlet.txt on the FTP server.
var localFilename = "moreHamlet.txt";
var remoteFilename = "hamlet.txt";

success = ftp.AppendFile(localFilename,remoteFilename);
if (success !== true) {
    console.log(ftp.LastErrorText);
    return;
}

success = ftp.Disconnect();

// Display the entire session log:
console.log(ftp.SessionLog);

console.log("File Appended!");
