🔩 Utility to parse and sort the "Content-Type" HTTP Header

Installation

Add this line to your application's Gemfile:

gem 'http_headers-content_type'

And then execute:

$ bundle

Or install it yourself as:

$ gem install http_headers-content_type

Usage

You can parse the "Content-Type" header. As per the RFCs, you should really have one (delimited) value but the current implementation accepts an array of values. Because there can only be one (1) Content-Type per request, it will always pick the last one, as per the RFCs.

require 'http_headers/content_type'

parsed = HttpHeaders::ContentType.new('application/json; charset=utf-8')
parsed.to_s
# => 'application/json; charset=utf-8'
parsed.content_type
# => 'application/json'
parsed.charset
# => 'utf-8'

 
parsed = HttpHeaders::ContentType.new([
  'application/json; charset=utf-8',
  'text/html; charset=utf-8; foo=bar'
])
parsed[:foo]
# => 'bar'
parsed.content_type
# => 'text/html'
parsed.charset
# => 'utf-8'

Each parsed value exposes the following methods:

  • content_type: the parsed content_type
  • charset: the charset parameter as string, or nil
  • [](parameter): accessor for the parameter; throws if it does not exist
  • to_s: encode back to an entry to be used in a Content-Type header

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
