Herokuにsinatraで簡単なApiサーバーを作る。

/Gemfile

source "https://rubygems.org"
ruby "2.2.2"
gem 'sinatra', '1.4.7'

/Procfile

web: bundle exec ruby app.rb -p $PORT

/config.rb

web: bundle exec rackup config.ru -p $PORT

/app.rb

require 'rubygems'
require 'sinatra'
require 'json'

get "/app" do
  json_data = open("settings/shuzo.json") do |io|
    JSON.load(io)
  end
  json_data["items"].each do | item |
      content_type :json
      if params["id"] == item["id"]
        body << item.to_json
      end
  end
  body
end

/settings/shuzo.json

{
  "items":[{
    "id":"1",
    "name":"Kuwako",
    "age":"29"
  },{
    "id":"2",
    "name":"Matsuoka",
    "age":"48"
  }]
}
