Check HTTP Status Code in Rails

Question

Is there an easy way to check the status code of another website (eg http://google.com ) in Ruby on Rails?

Ideally, the list of URLs to check would be pulled from a DB and processed via CRON (or equivalent).

Answer 1

require 'net/http'

http = Net::HTTP.new('www.google.com',80)
response = http.request_get('/')
p response.status

Slightly more efficient (traffic wise) might be:

response = http.request_head('/')
p response.status

Answer 2

You can access the request env by calling :

def index
  @req = (request.env).inspect 
end

# index.html.erb
<%= @req %>
