安全比较轮换器¶ ↑
ActiveSupport::SecureCompareRotator 是 ActiveSupport::SecurityUtils.secure_compare 的一个包装器,允许您将先前定义的值轮换为新值。
使用方式如下:
rotator = ActiveSupport::SecureCompareRotator.new('new_production_value') rotator.rotate('previous_production_value') rotator.secure_compare!('previous_production_value')
一个实际用例是轮换基本身份验证凭据
class MyController < ApplicationController def authenticate_request rotator = ActiveSupport::SecureCompareRotator.new('new_password') rotator.rotate('old_password') authenticate_or_request_with_http_basic do |username, password| rotator.secure_compare!(password) rescue ActiveSupport::SecureCompareRotator::InvalidMatch false end end end
