Send a Raw FTP Command and Get the Reply

Demonstrates the Chilkat Ftp2.SendCommand method, which sends a raw FTP command and returns the complete server reply. The only argument is the command text, which must not contain CR or LF.

Background: This is the escape hatch for commands the API does not wrap directly — it sends exactly what you provide and hands back the full reply for you to interpret. It is limited to commands that complete on the control connection; anything requiring a data connection (a listing or transfer) needs the dedicated methods, which set up the data channel. Note the command is sent as UTF-8 and CommandCharset is not applied.

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;

//  Demonstrates the Ftp2.SendCommand method, which sends a raw FTP command and returns the
//  complete server reply.  The only argument is the command text.  Use this for a command not
//  otherwise exposed by the API.

var ftp = new CkFtp2();

ftp.Hostname = "ftp.example.com";
ftp.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.Password = "myPassword";

//  Connect and log in (Connect performs both).
success = ftp.Connect();
if (success == false) {
    console.log(ftp.LastErrorText);
    return;
}

//  The command must not contain CR or LF characters.  Here PWD is sent as an example.
var reply = ftp.SendCommand("PWD");
if (ftp.LastMethodSuccess == false) {
    console.log(ftp.LastErrorText);
    return;
}

console.log(reply);

success = ftp.Disconnect();
if (success == false) {
    console.log(ftp.LastErrorText);
    return;
