ruby-on-rails - Rails - 如何更改 ActionController::RoutingError 的日志级别

Question

有没有办法更改 ActionController::RoutingError 的日志级别?
我想将其从错误更改为警告。 google了一下，没找到解决办法。。。
我只想将路由错误显示为警告。但不会更改其他日志记录行为。
此处描述了一种可能的解决方法(或该解决方法的一部分)https://stackoverflow.com/a/5386515/10272但这不是我想要的。在这个解决方案中，他们只是为找不到页面的错误添加一个包罗万象的路由器，然后在包罗万象的 Controller 中处理它。但我希望能够改变日志严重性，如果可能的话，它似乎更好地描述了我的意图......

我在 Rails 5.2 中使用以下初始化器解决了这个问题:

# /config/initializers/routing_error_logger_defatalizer.rb

# Spammers and script kiddies hit the site looking for exploits
# which blows up our logs as we get a bunch of fatal errors for 404s on eg. "/wp-admin.php"
# This initializer changes the log level of RoutingErrors to 'warn' (so they still appear in logs but are not fatal)
# this means we can use logging notifications on eg. >= error without all the false positives

if Rails.env.production?
  module ActionDispatch
    class DebugExceptions
      alias_method :old_log_error, :log_error
      def log_error(request, wrapper)
        if wrapper.exception.is_a?  ActionController::RoutingError
          # Have prepended "[404]" to the message for easier log searches, otherwise it is the default Rails messaging
          # Full message eg. "[404] ActionController::RoutingError (No route matches [GET] \"/wp-login.php\")"
          logger(request).send(:warn, "[404] ActionController::RoutingError (#{wrapper.exception.message})")
          return
        else
          old_log_error request, wrapper
        end
      end
    end
  end
end

对于 Rails 4.2 使用:

if Rails.env.production?
  class ActionDispatch::DebugExceptions # Rails 4.2
    alias_method :old_log_error, :log_error
    def log_error(request, wrapper)
      if wrapper.exception.is_a?  ActionController::RoutingError
        # Have prepended "[404]" to the message for easier log searches, otherwise it is the default Rails messaging
        # Full message eg. "[404] ActionController::RoutingError (No route matches [GET] \"/wp-login.php\")"
        logger(request).send(:warn, "[404] ActionController::RoutingError (#{wrapper.exception.message})")
        return
      else
        old_log_error request, wrapper
      end
    end
  end
end
