def params(content_type)
  return {} if content_type.nil?

  content_type.split(SPLIT_PATTERN)[1..-1].each_with_object({}) do |s, hsh|
    k, v = s.split('=', 2)

    hsh[k.tap(&:downcase!)] = strip_doublequotes(v)
  end
end

.type(content_type) ⇒ Object

The media type (type/subtype) portion of the CONTENT_TYPE header without any media type parameters. e.g., when CONTENT_TYPE is “text/plain;charset=utf-8”, the media-type is “text/plain”.
