200 => Found403 => Not authorized404 => Not found
我猜Rails 3已经有这个功能,因为你可以传递哈希来呈现：status => ：not_found,我只是找不到方法做到这一点.如果没有人知道可以做到这一点的宝石？
irb(main):001:0> Rack::Utils::HTTP_STATUS_CODES[200]=> "OK"irb(main):002:0> Rack::Utils::HTTP_STATUS_CODES[403]=> "Forbidden"irb(main):003:0> Rack::Utils::HTTP_STATUS_CODES[404]=> "Not Found"
要么
irb(main):004:0> Rack::Utils.status_code(:ok)=> 200irb(main):005:0> Rack::Utils.status_code(:forbidden)=> 403irb(main):006:0> Rack::Utils.status_code(:not_found)=> 404
