有没有办法更改ActionController::RoutingError的日志级别?
我想将它从错误更改为警告。谷歌搜索并没有找到解决方案...
我只想将路由错误显示为警告。但不能改变其他伐木行为 这里描述了一种可能的解决方法(或部分解决方法)https://stackoverflow.com/a/5386515/10272,但这并不是我想要的。在这个解决方案中,他们只是为页面未找到错误添加一个全能路由器,然后在catch-all-controller中处理它。但是我希望能够只更改日志严重性,如果可能的话,它似乎更能描述我的意图......

您可以覆盖Simple Formatter,以便将错误记录为警告。

但是,我不建议采用此路由,因为您最终会记录应用程序将其视为错误/异常的操作的警告消息。更优雅的选择是如您所描述的那样拥有一个包罗万象的页面,控制器捕获异常记录警告消息。

我在Rails 5.2中使用了初始化器中的以下代码解决了这个问题:

# /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
