Simple gem that parses the HTTP prefer header.
Add this line to your application's Gemfile:
gem 'rack-prefer'
And then execute:
$ bundle
Or install it yourself as:
$ gem install rack-prefer
# rack app (sinatra, lotus, grape etc)
require 'rack/prefer'
Rails automatically includes the rack/prefer
file.
Once you have access to Rack::Request object (Rails ActionDispatch::Request object inherits from Rack's Rack::Request) you also have access to Prefer header. So for a request like the following prefer headers:
Prefer: respond-async, wait=10
Prefer: priority=5
Prefer: handling=strict
you can do:
request.prefer.values #{"respond-async"=>nil, "wait"=>"10", "priority"=>"5"}
request.prefer.response_async? #true
request.prefer.return_minimal? #false
request.prefer.wait? #true
request.prefer.wait # 10 (integer)
request.prefer.handling_strict? #true
request.prefer.values['handling'] #'strict'
#Rails only
request.prefer.values[:handling] #strict
Happy coding!
