我想在登台服务器上实现HTTP基本身份验证,但仅适用于本地网络之外的身份验证.我有一个Rails 3.1应用程序.在application.rb中,我有以下内容:
- class ApplicationController << ActionController::Base
- http_basic_authenticate_with :realm => "Staging",:name => "user",:password => "password" if :need_authentication?
- private
- def need_authentication?
- Rails.env == "staging" && request.remote_addr !~ /^192.168.0.\d{1,3}$/
- end
- end
这就是问题:即使是need_authentication?方法显式返回false,应用程序仍然要求我进行身份验证,就好像它完全忽略了最后的if子句一样.
那么,有没有办法只在某些条件下要求身份验证?
解决方法
在Rails 4中,:if条件有效.例如,
- class ApplicationController < ApplicationController::Base
- http_basic_authenticate_with name: "user",password: "password" if Rails.env == 'staging'
- end
或者如果你想要一个辅助方法来设置条件,
- class ApplicationController < ApplicationController::Base
- http_basic_authenticate_with name: "user",password: "password",if: :need_authentication?
- private
- def need_authentication?
- Rails.env == 'staging'
- end
- end
