Setting an HTTP Timeout in Ruby 1.9.3

I'm using Ruby 1.9.3 and need to GET a URL. I have this working with

Net::HTTP
, however, if the site is down,
Net::HTTP
ends up hanging.

While searching the internet, I've seen many people faced similar problems, all with hacky solutions. However, many of those posts are quite old.

Requirements:


  • I'd prefer using
    Net::HTTP
    to installing a new gem.

  • I need both the Body and the Response Code. (e.g. 200)

  • I do not want to
    require open-uri
    , since that makes global changes and raises some security issues.

  • I need to GET a URL within X seconds, or return error.



Using Ruby 1.9.3, how can I GET a URL while setting a timeout?




To clarify, my existing code looks like:

Net::HTTP.get_response(URI.parse(url))


Trying to add:

Net::HTTP.open_timeout(1000)


Results in:

NoMethodError: undefined method `open_timeout' for Net::HTTP:Class

Answer

You can set the open_timeout attribute of the Net::HTTP object before making the connection.

uri = URI.parse(url)
Net::HTTP.new(uri.hostname, uri.port) do |http|
  http.open_timeout = 1000
  response = http.request_get(uri.request_uri)
end
