server.rb

require 'sinatra'

#前置过滤器

  puts 'before process'
end

#后置过滤器

  puts 'after process'
end

#找不到页面调用的逻辑
not_found do
  '

'
end

get '/' do
  '
Hello World
'
end

#渲染views/index.erb模板
get '/show' do
  erb :index
end

#渲染views/success.erb模板
post '/submit' do
  @email = '[email protected]'
  @email2 = params['email']
  @url = request.url
