OpenUriRedirections

This gem applies a patch to OpenURI to optionally allow redirections from HTTP to HTTPS, or from HTTPS to HTTP.

UPDATE 2019: HTTP to HTTPS is supported by native open-uri by default from Ruby 2.4.

This is based on this patch and this gem, and modified to allow redirections in both directions.

Here is the problem it tries to solve:

$ irb
1.9.2p320 :001 > require 'open-uri'
=> true
1.9.2p320 :002 > open('http://github.com')
RuntimeError: redirection forbidden: http://github.com -> https://github.com/

And here is how you can use this patch to follow the redirections:

$ irb
1.9.2p320 :001 > require 'open-uri'
=> true
> require 'open_uri_redirections'
=> true
1.9.2p320 :002 > open('http://github.com', :allow_redirections => :safe)
=> #<File:/var/folders/...>

The patch contained in this gem adds the :allow_redirections option to OpenURI#open:

• :allow_redirections => :safe will allow HTTP => HTTPS redirections.
• :allow_redirections => :all will allow HTTP => HTTPS redirections and HTTPS => HTTP redirections.
