如何在Webrick服务器上执行代码

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
