Instance Method Details

#fingerprint(fingerprints, opts = {}) {|Mixed, String, String| ... } ⇒ Object

Format should be like the following: {

file_path_1: {
  md5_hash_1: version_1,
  md5_hash_2: [version_2]
},
file_path_2: {
  md5_hash_3: [version_1, version_2],
  md5_hash_4: version_3
}

} Note that the version can either be an array or a string

Parameters:

  • fingerprints (Hash) —

    The fingerprints

  • opts (Hash) (defaults to: {})

Options Hash (opts):

  • :show_progression (Boolean) —

    Wether or not to display the progress bar

Yields:

  • (Mixed, String, String) —

    version/s, url, hash The version associated to the fingerprint of the url

def fingerprint(fingerprints, opts = {})
  enum_opts = opts.merge(check_full_response: 200)

  enumerate(fingerprints.transform_keys { |k| target.url(k) }, enum_opts) do |res, fingerprint|

    next unless fingerprint.key?(md5sum)

    yield fingerprint[md5sum], res.effective_url, md5sum
  end
end

#hexdigest(body) ⇒ String

Returns The hashed value for the given body.

Returns:

  • (String) —
