Demonstrate how to upload from a Chilkat StringBuilder object, and download into a StringBuilder object.

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 assumes Chilkat Ftp2 to have been previously unlocked.
// See Unlock Ftp2 for sample code.

var ftp = new CkFtp2();

ftp.Hostname = "www.my-ftp-server.com";
ftp.Username = "mFtpLogin";
ftp.Password = "myFtpPassword";

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

// Authenticate with the FTP server.
success = ftp.LoginAfterConnectOnly();
if (success !== true) {
    console.log(ftp.LastErrorText);
    return;
}

var sbA = new CkStringBuilder();
sbA.LoadFile("qa_data/hamlet.xml","utf-8");

// Upload the contents of sbA to the FTP server.
var bIncludeBOM = false;
var remoteFilename = "hamletFromSb.xml";
success = ftp.PutFileSb(sbA,"utf-8",bIncludeBOM,remoteFilename);
if (success !== true) {
    console.log(ftp.LastErrorText);
    return;
}

// Download...
var sbB = new CkStringBuilder();
success = ftp.GetFileSb(remoteFilename,"utf-8",sbB);
if (success !== true) {
    console.log(ftp.LastErrorText);
    return;
}

// Verify that sbA and sbB have the exact same contents.
console.log("size of sbA: " + sbA.Length);
var bCaseSensitive = true;
if (sbA.ContentsEqualSb(sbB,bCaseSensitive) == true) {
    console.log("Contents are equal. Success.");
}
else {
    console.log("Contents are NOT equal.  Failed.");
}

ftp.Disconnect();
