Rails3/ruby​​ gem中是否有一个方法,它将状态代码映射到消息？

Question

如

200 => Found
403 => Not authorized
404 => Not found

我猜Rails 3已经有了这个功能,因为你可以传递哈希render :status => :not_found,我只是找不到方法来做其他方式.如果没有人知道可以做到这一点的宝石？

Answer 1

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)
=> 200
irb(main):005:0> Rack::Utils.status_code(:forbidden)
=> 403
irb(main):006:0> Rack::Utils.status_code(:not_found)
=> 404
