Question

How do I download a file over HTTP using Ruby?

Answer 1

There are several ways, but the easiest is probably OpenURI. This blog post has some sample code, and also goes over Net::HTTP (with Hpricot) and Rio.

Answer 2

Simple...

response = Net::HTTP.get_response(URI.parse("yourURI"))

Answer 3

require 'net/http'
#part of base library
Net::HTTP.start("your.webhost.com") { |http|
  resp = http.get("/yourfile.xml")
  open("yourfile.xml", "wb") { |file|
    file.write(resp.body)
  }
}
