Asynchronous HTTP Upload

Demonstrates how to do an HTTP upload asynchronously in a background thread. The Chilkat Upload software is freeware and may be used in both commercial and non-commercial applications and websites.

The C# code to receive the upload at http://www.chilkatsoft.com/receiveUpload.aspx may be seen here: C# ASP.NET Code to Receive Upload

Download Chilkat Ruby Library

require 'chilkat'

upload = Chilkat::CkUpload.new()

#  Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
#  that will process the HTTP Upload.
upload.put_Hostname("www.chilkatsoft.com")
upload.put_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")

#  Begin the HTTP upload in a background thread:
success = upload.BeginUpload()
if (success != true)
    print upload.lastErrorText() + "\n"
else
    print "Files uploaded!" + "\n"
end

#  Wait for the upload to finish.
#  Print the progress as we wait...
while (upload.get_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:
    print upload.get_PercentUploaded().to_s().to_s() + 
        "% " + upload.get_NumBytesSent().to_s().to_s() + 
        "/" + upload.get_TotalUploadSize().to_s().to_s() + "\n";

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

end

#  Did the upload succeed?
if (upload.get_UploadSuccess() == true)
    print "Files uploaded!" + "\n"
else
    print upload.lastErrorText() + "\n"
end
