The parameters sent to the request is printed to your log file in development.

If you look at the last few hundred lines of log/development.log you will find something that looks roughly like:

Started GET "/?page=2" for 127.0.0.1 at 2012-07-01 03:05:05 -0600
Processing by ListsController#index as JSON
  Parameters: {"page"=>"2"}

You can enhance this by inspecting the object from your controller or, as mentioned by Ben.

You can have this output to the logfile by using Rails.logger.debug params.inspect or output it in the response from your view by doing <%= params.inspect %>

In your controller method, just inspect the params hash. For example,

class UsersController < ApplicationController
  def index
    puts params.inspect
  end
end

You can also view these params as part of the request using something like Chrome Developer Tools or Firebug.
