Answer 1

According to the README file of the rubyzip gem, the correct class to use is Zip::File . You can read a zip file by using

Zip::File.open('foo.zip') do |zip_file|
  # Handle entries one by one
  zip_file.each do |entry|
    # Extract to file/directory/symlink
    puts "Extracting #{entry.name}"
    entry.extract(dest_file)

    # Read into memory
    content = entry.get_input_stream.read
  end

  # Find specific entry
  entry = zip_file.glob('*.csv').first
  puts entry.get_input_stream.read
end

Please read the documentation available to you.
