params(content_type)

The media type parameters provided in CONTENT_TYPE as a Hash, or an empty Hash if no CONTENT_TYPE or media-type parameters were provided. e.g., when the CONTENT_TYPE is “text/plain;charset=utf-8”, this method responds with the following Hash:

{ 'charset' => 'utf-8' }
# File lib/rack/media_type.rb, line 24
def params(content_type)
  return {} if content_type.nil?
  Hash[*content_type.split(SPLIT_PATTERN)[1..-1].
    collect { |s| s.split('=', 2) }.
    map { |k,v| [k.downcase, strip_doublequotes(v)] }.flatten]
end
type(content_type)

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”.
