rack-filter-param

Refactoring something behind an API? Plagued by extraneous HTTP params? rack-filter-param might be for you.

What is it?

Rack middleware to remove specific params from HTTP requests.

What does it do?

Given a set of params and optional constraints, rack-filter-param will remove those params, then pass the request downstream.

Removes params from:

Installation


gem 'rack-filter-param', require: 'rack/filter_param'

Usage

In rackup file or application.rb, initialize rack-filter-param with a list of HTTP params you want filtered from requests.

Strip a parameter named client_id:

use Rack::FilterParam, :client_id

Strip a parameter named client_id from a specific path only:

use Rack::FilterParam, { param: :client_id, path: '/oauth/tokens' }

Strip a parameter named client_id from a fuzzy path:

use Rack::FilterParam, { param: :client_id, path: /\A\/oauth/ }

To filter multiple parameters, an array of parameters or options hashes can also be passed.
