Open_uri.rb -- 500 Internal Server Error

Ruby
1

Hello to all,
I am using ‘open-uri’ & ‘pp’ ruby library, to open url and gather some
data from given web page. But it throws following error

c:/ruby/lib/ruby/1.8/open-uri.rb:278:in open_http': 500 Internal Server Error ( OpenURI::HTTPError) from c:/ruby/lib/ruby/1.8/open-uri.rb:617:in buffer_open’
from c:/ruby/lib/ruby/1.8/open-uri.rb:164:in open_loop' from c:/ruby/lib/ruby/1.8/open-uri.rb:162:in catch’
from c:/ruby/lib/ruby/1.8/open-uri.rb:162:in open_loop' from c:/ruby/lib/ruby/1.8/open-uri.rb:132:in open_uri’
from c:/ruby/lib/ruby/1.8/open-uri.rb:519:in open' from c:/ruby/lib/ruby/1.8/open-uri.rb:30:in open’
from openmyurl.rb:4

source code openurl.rb is like-----

require ‘open-uri’
require ‘pp’

open(‘http://www.aflatune.com/’) do |f|

hash with meta information

pp f.meta

pp "Content-Type: " + f.content_type
pp “last modified” + f.last_modified.to_s

no = 1

print the first fifty lines

f.each do |line|
print “#{no}: #{line}”
no += 1
break if no > 50
end
end

can any one give me solution to how to solve this problem?

looks like the aflatune-Webserver throws a 500 error if no User-Agent is
set.

this works for me:
open(‘http://www.aflatune.com/’, ‘User-Agent’=>‘ruby’)
