Overview
During your load test, you may want your virtual user to connect to an FTP server to upload or download some files. This can be done through a NeoLoad JavaScript. Here is an example of how to use FTP within a JavaScript using the FTPClient packages. FTPClient encapsulates all the functionality necessary to store and retrieve files from an FTP server.
We have provided the basics to send and receive a file, create and change directories, etc.
See a full list of FTPClient commands: https://commons.apache.org/proper/commons-net/apidocs/org/apache/commons/net/ftp/FTPClient.html#changeWorkingDirectory(java.lang.String).
The Best Solution for you to Consider
Copy and paste these code snippets into a skeleton JavaScript in your user path.
NOTE: It is always required to have the Initialization routine placed first to connect to your FTP server before performing the additional actions. Also, note that it’s recommended to include myFTPClient.logout(); and myFTPClient.disconnect(); at the end of your script to close your session’s connection.
// Initialization (required to connect, fill in servername, username and password)
myFTPClient =new Packages.org.apache.commons.net.ftp.FTPClient(); myFTPClient.connect(“servername”); myFTPClient.login(“username”,”password”); logger.debug(myFTPClient.getReplyCode()+” “+myFTPClient.getReplyString());
//Create a new folder with MKDIR command
myFTPClient.makeDirectory(“FTPNeoload”); logger.debug(myFTPClient.getReplyCode()+” “+myFTPClient.getReplyString());
//Change directory command
myFTPClient.changeWorkingDirectory(“FTPNeoload”); logger.debug(myFTPClient.getReplyCode()+” “+myFTPClient.getReplyString());
NOTE: Using PUT or GET methods may require switching your FTP connection into passive transfer mode. To do that add this one line command:
// Put FTP file transfer into passive mode
myFTPClient.enterLocalPassiveMode();
//Use of the GET method
var writer = new java.io.FileOutputStream(“c:\\Temp\\MyFile.zip”,true);
myFTPClient.retrieveFile(“MyFile.zip”,writer);
writer.close();
logger.debug(myFTPClient.getReplyCode()+” “+myFTPClient.getReplyString());
//Use of the PUT method
var reader = new java.io.FileInputStream(“c:\\Temp\\myfile.xps”); myFTPClient.storeFile(“myfile.xps”,reader);
reader.close();
logger.debug(myFTPClient.getReplyCode()+” “+myFTPClient.getReplyString());
//Command PWD (Print Working Directory)
myFTPClient.printWorkingDirectory(); logger.debug(myFTPClient.getReplyCode()+” “+myFTPClient.getReplyString());
//Command LIST
engine =myFTPClient.initiateListParsing(“/”);
while (engine.hasNext())
{
file = engine.getNext(5);
logger.debug(file[0].getName());
}
