(Ruby) Create a Zip Entirely in MemoryDemonstrates how to create a .zip from in-memory byte data and strings, and to write the .zip to an in-memory image. Note: This example requires Chilkat v11.0.0 or greater.
require 'chilkat' success = false # This example requires the Chilkat API to have been previously unlocked. # See Global Unlock Sample for sample code. crypt = Chilkat::CkCrypt2.new() zip = Chilkat::CkZip.new() success = zip.NewZip("test.zip") if (success == false) print zip.lastErrorText() + "\n"; exit end # Add the bytes 0x00 0x01 0x02 0x03 ... 0x0F as a file in the .zip bd = Chilkat::CkBinData.new() bd.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex") zip.AddBd("binaryData.dat",bd) # Add the string "Hello World!" to the .zip zip.AddString("helloWorld.txt","Hello World!","utf-8") zipFileInMemory = Chilkat::CkByteData.new() success = zip.WriteToMemory(zipFileInMemory) # We could save these files to a file, and it is a valid .zip fac = Chilkat::CkFileAccess.new() success = fac.WriteEntireFile("test.zip",zipFileInMemory) if (success == false) print fac.lastErrorText() + "\n"; exit end print "Zip Created!" + "\n"; |
