Code to accompany the weblog posting: Ruby/Rack and Multiple Value Request Param Pain — Part Two

Demonstrates problems with some Ruby HTTP clients when dealing with multi-value params

client.rb

require 'rubygems'
require 'patron'
require 'typhoeus'

def req_typhoeus(several=nil)
  if several then
    response = Typhoeus::Request.post("http://localhost:4567/", params: { 'several' => several } )
  else
    response = Typhoeus::Request.post("http://localhost:4567/")
  end
  puts "typhoeus :: status: #{ response.code }, body: #{ response.body }"
end

def req_patron(several=nil)
  request = Patron::Session.new

  if several then
    response = request.post('http://localhost:4567/', { 'several' => several })
  else
    response = request.post('http://localhost:4567/', { })
  end
  puts "patron   :: status: #{ response.status }, body: #{ response.body }"
end

def req(several=nil)
  req_patron(several)
  req_typhoeus(several)
end

req
req('hello')
req(%w{ one two three })

server.rb

require 'rubygems'
require 'sinatra'

#require 'rack-monkey-patch'
  
post '/' do
  puts "#{File.basename(__FILE__)}:#{__LINE__} #{ __method__ } params: #{ params.inspect }"
    
  several = params[:several]
  
  puts "several(#{ several.class.name }) --> #{ several.inspect }"

  case several
  when String
    "String --> #{ several }"
  when Array 
    "Array[#{ several.size }] --> #{ several.join('-') }"
  else
    "eh?"
  end
end
