A middleware to process wrong encoded URLs in Rack applications.
This software has been tested in following environments:
- Ruby 1.9.3
- Ruby 2.0
- Ruby 2.1
- Ruby 2.2
- JRuby
- Rubinius 2
gem install rack-encoding_guard
If you are using Bundler add the following line to your Gemfile:
gem 'rack-encoding_guard', '~> 0.1'If you are on Rails, you can insert the middleware into your application.rb
config.middleware.use 'Rack::EncodingGuard::Middleware'This is the default strategy. When using sanitization strategy, all invalid characters will be stripped out of all relevant ENV vars. Subsequently, no encoding errors will occur down the middleware stack.
config.middleware.use 'Rack::EncodingGuard::Middleware', :sanitizeWhen using reject strategy, all requests containing invalid characters are rejected with a HTTP 400 status ("Bad Request"). Additionally, you can override which message will be displayed to the requesting user:
config.middleware.use 'Rack::EncodingGuard::Middleware', :reject, with: 'Check that URL, mate!'You can test the result of the different strategies with the following bash command:
curl "localhost:3000/?test=�S��7�砱�y�����g�d��C���|��W��O�s��~����*6��@�4�&�A�J����"- Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
- Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
- Fork the project.
- Start a feature/bugfix branch.
- Commit and push until you are happy with your contribution.
- Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
- Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
