how to excute code on webrick server - ruby

Question

I start a webrick server like this:
dell#dev:/var/www/ruby$ ruby -run -httpd. -p 5000
and have this code in abc.rb:
require 'webrick'
root = File.path '/tmp/public_html'
server = WEBrick::HTTPServer.new :Port => 5000, :DocumentRoot => root
trap 'INT' do server.shutdown end
server.start
ary = { "0"=>"fred", "1"=>10, "2"=>3.14, "3"=>"This is a string", "4"=>"last element", }
ary.each do |key, value|
puts "#{key} #{value}"
end
When I run this code it shows me the same code on browser
http://localhost:5000/abc.rb
How can I view the output this code, I have already asked this question and did not get any correct answer :(
Is it the right code? I want to know this, where this code place
require 'webrick'
root = File.path '/tmp/public_html'
server = WEBrick::HTTPServer.new :Port => 5000, :DocumentRoot => root
trap 'INT' do server.shutdown end
server.start
if any one give me step by step ans to run this code i am very thankful.. I don't understand the ans :( how to do this

Answer 1

From the documentation:
The easiest way to have a server perform custom operations is through
WEBrick::HTTPServer#mount_proc. The block given will be called with a
WEBrick::HTTPRequest with request info and a WEBrick::HTTPResponse
which must be filled in appropriately:
server.mount_proc '/' do |req, res|
res.body = 'Hello, world!'
end
Remember that server.mount_proc must server.start.
So:
require 'webrick'
root = File.path '/tmp/public_html'
server = WEBrick::HTTPServer.new :Port => 5000, :DocumentRoot => root
server.mount_proc '/abc.rb' do |req, res|
ary = { "0"=>"fred", "1"=>10, "2"=>3.14, "3"=>"This is a string", "4"=>"last element" }
res.body = ary.map do |key, value|
"#{key} #{value}"
end.join("\n")
end
trap 'INT' do server.shutdown end
server.start
Also, I believe the correct way to start your WebBrick is by running:
ruby abc.rb
