unzipping a zip archive from a string

I have a zip archive in a string, but the rubyzip gem appears to want input from a file. The best I've come up with is to write the zip archive to a tempfile for the sole purpose of passing the filename to Zip::ZipFile.foreach(), but this seems tortured:

require 'zip/zip'
def unzip(page)
  "".tap do |str|
    Tempfile.open("unzip") do |tmpfile|
      tmpfile.write(page)
      Zip::ZipFile.foreach(tmpfile.path()) do |zip_entry|
        zip_entry.get_input_stream {|io| str << io.read}
      end
    end
  end
end

Is there a simpler way?

NOTE: See also Ruby Unzip String.

Solution

  • See Zip/Ruby Zip::Archive.open_buffer(...):

    require 'zipruby'
Zip::Archive.open_buffer(str) do |archive|
  archive.each do |entry|
    entry.name
    entry.read
  end
end
