Ruby - net/http - following redirects

Question

I\'ve got a URL and I\'m using HTTP GET to pass a query along to a page. What happens with the most recent flavor (in net/http) is that the script doesn\'t go

Answer 1

Given a URL that redirects

url = 'http://httpbin.org/redirect-to?url=http%3A%2F%2Fhttpbin.org%2Fredirect-to%3Furl%3Dhttp%3A%2F%2Fexample.org'

A. Net::HTTP

begin
  response = Net::HTTP.get_response(URI.parse(url))
  url = response['location']
end while response.is_a?(Net::HTTPRedirection)

Make sure that you handle the case when there are too many redirects.

B. OpenURI

open(url).read

OpenURI::OpenRead#open follows redirects by default, but it doesn't limit the number of redirects.
