Class FTPClient
Object
dw.net.FTPClient
The FTPClient class supports the FTP commands CD, GET, PUT, DEL, MKDIR, RENAME, and LIST. The FTP connection is established using passive transfer mode (PASV). The transfer of files can be text or binary.

Note: when this class is used with sensitive data, be careful in persisting sensitive information to disk.

An example usage is as follows:

 
  var ftp : FTPClient = new dw.net.FTPClient();
  ftp.connect("my.ftp-server.com", "username", "password");
  var data : String = ftp.get("simple.txt");
  ftp.disconnect();
 
 

The default connection timeout depends on the script context timeout and will be set to a maximum of 30 seconds (default script context timeout is 10 seconds within storefront requests and 15 minutes within jobs).

IMPORTANT NOTE: Before you can make an outbound FTP connection, the FTP server IP address must be enabled for outbound traffic at the Commerce Cloud Digital firewall for your POD. Please file a support request to request a new firewall rule.

This method can be called at any time, and will affect the next connection made with this client. It is not possible to set the timeout for an open connection.

Parameters:
timeoutMillis - timeout, in milliseconds, up to a maximum of 2 minutes.
