Making an HTTP request to an external machine


#1

During one of my controller actions I want to call an external machine
before I do anything. It’s not a real web service, more like a
REST-style thing where I’ll just be tweaking a servlet running on
another machine and sending it some data.

Does Rails give me anything to work with for doing that? I read the web
service stuff but it’s overkill for what I need. I just need to open up
an http connection, send some data, and then check to see what response
I got back.

Rails doesn’t, since that’s already in Ruby’s standard library. Look
at Net::HTTP
(http://www.ruby-doc.org/stdlib/libdoc/net/http/rdoc/index.html).

open-uri is easier.

require ‘open-uri’

open ‘http://example.com/service/endpoint?param=value’ do |fp|

… fp is an IO-like object

end
