Demonstrates how to download a .zip from a URL, opens the Zip, and gets the contents of a file. No file is ever written. Ruby

require 'chilkat'

success = false

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

http = Chilkat::CkHttp.new()

bd = Chilkat::CkBinData.new()

# This URL is valid and can be tested...
success = http.QuickGetBd("https://chilkatdownload.com/example_data/hamlet.zip",bd)
if (http.get_LastMethodSuccess() == false)
    print http.lastErrorText() + "\n";
    exit
end

zip = Chilkat::CkZip.new()

# Open the zip from the bytes contained in bd.
success = zip.OpenBd(bd)
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

# Get the entry for the file we want..
entry = Chilkat::CkZipEntry.new()
success = zip.EntryOf("hamlet.xml",entry)
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

# Convert all line endings to CRLF (if needed)
lineEndingBehavior = 2
xmlStr = entry.unzipToString(lineEndingBehavior,"utf-8")
if (entry.get_LastMethodSuccess() == false)
    print entry.lastErrorText() + "\n";
    exit
end

# The XML in this case is about 274K, so let's just examine the last 20 lines...
sb = Chilkat::CkStringBuilder.new()
sb.Append(xmlStr)

print sb.lastNLines(20,true) + "\n";
