(JavaScript) SFTP Read Directory Listing

Demonstrates how to download a directory listing and iterate over the files.

Note: This example requires Chilkat v11.0.0 or greater.

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

// Important: It is helpful to send the contents of the
// sftp.LastErrorText property when requesting support.

var sftp = new CkSFtp();

// Set some timeouts, in milliseconds:
sftp.ConnectTimeoutMs = 5000;
sftp.IdleTimeoutMs = 10000;

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.
var hostname = "www.my-sftp-server.com";
var port = 22;
success = sftp.Connect(hostname,port);
if (success == false) {
    console.log(sftp.LastErrorText);
    return;
}

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.
success = sftp.AuthenticatePw("myLogin","myPassword");
if (success == false) {
    console.log(sftp.LastErrorText);

// After authenticating, the SFTP subsystem must be initialized:
success = sftp.InitializeSftp();

    console.log(sftp.LastErrorText);
    return;
}

// Open a directory on the server...
// Paths starting with a slash are "absolute", and are relative 
// to the root of the file system. Names starting with any other 
// character are relative to the user's default directory (home directory).
// A path component of ".." refers to the parent directory, 
// and "." refers to the current directory. 
var handle = sftp.OpenDir(".");
if (sftp.LastMethodSuccess == false) {
    console.log(sftp.LastErrorText);

// Download the directory listing:

var dirListing = new CkSFtpDir();
success = sftp.ReadDirListing(handle,dirListing);
if (success == false) {
    console.log(sftp.LastErrorText);
    return;
}

// Close the handle for the directory listing.
success = sftp.CloseHandle(handle);
if (success == false) {
    console.log(sftp.LastErrorText);
    return;
}

// Iterate over the files.
var fileObj = new CkSFtpFile();
var i = 0;
var n = dirListing.NumFilesAndDirs;
while (i < n) {

    success = dirListing.FileAt(i,fileObj);
    if (success == false) {
        console.log(dirListing.LastErrorText);
        return;
    }

    console.log(fileObj.Filename);
    console.log(fileObj.FileType);
    console.log("Size in bytes: " + fileObj.Size32);
    console.log("----");

    i = i+1;
}

console.log("Success.");
