Grape Path and Header Versioning

Illustrates how path and header versioning can be used side by side for different versions. See this blog post for the original discussion

To run example:

bundle
ruby api.rb

api.rb

require 'bundler'
Bundler.require :default

require 'grape'
require 'rack-test'
class API < Grape::API
  version 'v2', using: :header, vendor: 'example'
  get '/hello' do
    "I am version 2"
  end

  version 'v1', using: :path
  get '/hello' do
    "I am version 1"
  end
end

include Rack::Test::Methods
def app
  API
end

get '/v1/hello'
puts "with path version v1: " + last_response.body
puts

get '/hello'
puts "with no version specified in header, defaults to latest available version: " + last_response.body
puts

get '/hello', {}, {'HTTP_ACCEPT' => 'application/vnd.example-v2+txt'}
puts "with header version v2: " + last_response.body
puts
