http proxy, in 15 lines

cactus · 2005-07-13 05:23:42

Someone in irc was asking about a simple http proxy the other day. I scratched around in some ruby, and came up with a *very* simple one..in 15 lines of code. Yeah, I know..I am prone to verbosity..

Something to fiddle with, in any regard.
super simple http-proxy

A slightly more complete version. Plays a bit nicer with things like wget and links.
simple http-proxy

Lookout! code bloat! feature creep!

I raise you one and give you one in python in 4 lines.

or the slightly more readable version

https://iphitus.loudas.com/arch/proxy/9lineproxy.py

though it still doesnt do http post. which means you cant do forums, etc, im fiddling on one that does http post now...

cactus · 2005-07-13 07:08:05

well, like i said, mine was a tad verbose. I actual was outputting useful text.
EDIT: Your links dont go anywhere iphitus..

meh, didnt have anything else to do I'm trying to make mine do POST requests.. which isnt easy.

cactus · 2005-07-13 07:23:53

yeah. get is pretty easy. post, and cookies...that would be harder.

Hi,

basic post-support:

#!/usr/bin/env ruby
require 'socket'
require 'open-uri'

server = TCPServer.new('127.0.0.1', 9090)

while (session = server.accept)
  request = ""
  response = ""
    
  while (r = session.gets) and r.strip.any?
    request += r
  end
  puts request
  r_type, url_request = (request.split(/ /))
  begin
    case r_type
      when /POST/
        uri = URI.parse(url_request)                
                if uri.is_a?(URI::HTTPS)
                  raise "sorry, no https possiblen"
        end
        content_length = request.scan(/Content-Length: ([0-9]+)rn/i).flatten[0].to_i
        content = session.read(content_length)
                Net::HTTP.start(uri.host, uri.port) do |http|
                  response = http.post(uri.path,content).body
        end
      when /GET/
        open(url_request) do |file|
          response = file.read
        end
      else
        raise "unknown request-type: #{r_type}"
        end
  rescue => e
    response = "Error: "+e.to_s
  end
  session.print response
  session.close
end

In what way would you use rails to write a proxy?

:oops: threading nappin' sorry

jochen · 2005-07-13 16:33:33

Btw. this proxy runs great on my linksys wrt54gs with openwrt firmware. I tried to run rails there too. But no chance, it eats way too much resources. Sure it works, but just about 0.2 pages per second :shock:

LOL, you running OpenWrt?

It's kinda funny you're using cactus' mini-proxy on your router 8)

jochen · 2005-07-13 16:45:54

yeah, this little box can be almost everything you want it to be when using openwrt.

cactus · 2005-07-14 04:52:17

thanks to jochen, i added post support. Works with both post and get urls..
like post to get type urls even
eg. http://localhost/index.php?type=no

http-proxy.rb
heh..i might try adding cookie support next.

cactus · 2005-07-16 08:03:58

cookie support is mostly working. Not sure if it allows creating a new cookie, or if it just uses an old cookie.

I may add some threading soon, as it only requests and returns pages sequentially.
heh. nothing like wasting time on silly code.

jochen · 2005-07-16 13:31:23

For threading I would suggest subclassing from GServer http://www.ruby-doc.org/stdlib/libdoc/g … erver.html

oooh.
