getやpost等をmethodとして呼び出す

methodsの中をpで見たら"GET /count"等があったので、callしてみたらふつうにwebブラウザでアクセスした時にうけとる文字列が返ってきた。erb等が使われている場合はerbを通した後の文字列（html）が返ってきた。

require 'rubygems'
require 'sinatra'
require 'rack'

@@arr = [1,2,3,4,5]

get '/' do
  p methods
  @count = method('GET /count').call
  @sum = method('GET /sum').call
  "count:#{@count}, sum:#{@sum}<br />
  #{methods.join('<br />')}"
end

get '/count' do
  @@arr.size.to_s
end

get '/sum' do
  @@arr.inject{|a,b|a+b}.to_s
end
