(JavaScript) Asynchronous HTTPS Upload (TLS)

Demonstrates how to do an HTTPS (TLS) upload asynchronously in a background thread.

A server-side C# example showing how to receive an upload is located at C# ASP.NET Code to Receive Upload

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;

var upload = new CkUpload();

// Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
// that will process the HTTP Upload.
upload.Hostname = "www.mywebserver.com";
upload.Path = "/receiveUpload.aspx";

// Add one or more files to be uploaded.
upload.AddFileReference("file1","dude.gif");
upload.AddFileReference("file2","pigs.xml");
upload.AddFileReference("file3","sample.doc");

// To upload using SSL/TLS (https), set the Ssl property = true
upload.Ssl = true;

// Begin the HTTP upload in a background thread:
success = upload.BeginUpload();
if (success !== true) {
    console.log(upload.LastErrorText);
}
else {
    console.log("Upload started..");
}

// Wait for the upload to finish.
// Print the progress as we wait...
while ((upload.UploadInProgress == true)) {
    // We can abort the upload at any point by calling:
    // upload.AbortUpload();

    // Display the percentage complete and the number of bytes uploaded so far..
    // The total upload size will become set after the upload begins:
    console.log(upload.PercentUploaded + "% " + upload.NumBytesSent + "/" + upload.TotalUploadSize);

    // Sleep 2/10ths of a second.
    upload.SleepMs(200);

}

// Did the upload succeed?
if (upload.UploadSuccess == true) {
    console.log("Files uploaded!");
}
else {
    console.log(upload.LastErrorText);
}
