Question

I am trying to run a ruby script from my computer and I would like to have the script use a proxy IP address / server that I have setup, as opposed to the default IP address associated with my local machine.

I have been able to get my web browsers to use this proxy IP address by making changes inside network settings. But When I run the ruby script from textmate, it doesn’t seem to use the proxy IP address I have put into my network settings. Instead it defaults back to the base ip address of my local machine.

Is there anything I can do in textmate or in the script itself to specify a proxy IP address it should route through?

My script looks like the following:

require "open-uri"
url = "some-url"
pattern = "<img"   


page = open(url).read
tags = page.scan(pattern)
puts "The site #{url} has #{tags.length} img tags"

Thanks for your help!

Use :proxy option to let open-uri know your proxy server:

page = open(url, :proxy => "http://#{proxy_host}:#{proxy_port}/").read

You can also set environment variable http_proxy instead. If you do so, give :proxy => true for option.

page = open(url, :proxy => true).read

[ADDED]

If you want to use proxy with basic authentication, you can give :proxy_http_basic_authentication option instead of :proxy as follows:

:proxy_http_basic_authentication => ["http://#{proxy_host}:#{proxy_port}/", login, password]

Note that :proxy_http_basic_authentication can be used in ruby 1.9.2 or later.
