如何在生产日志文件中禁用 Rails RoutingError 堆栈跟踪打印输出？答案

【问题标题】：How to disable Rails RoutingError stacktrace printout in Production log files?如何在生产日志文件中禁用 Rails RoutingError 堆栈跟踪打印输出？

【问题描述】：

在我的骄傲 Rails 应用程序中，我遇到了各种类型的随机攻击，要求获取 asp、zip 和 rar 文件。 Rails 按预期呈现 404 页面，但我的生产日志文件被 RoutingError 堆栈跟踪转储卡住，如下所示。

我的问题是：我可以在 Apache/Passenger 中阻止具有特定模式的 URL 吗？或者至少我可以将 Rails 配置为只记录错误本身而不打印整个堆栈跟踪？谢谢！

Rendering /myapp/public/404.html (404 Not Found)

【问题讨论】：

标签： ruby-on-rails logging stack-trace production

【解决方案1】：

Rails 4 和 5 答案：

match '*any', to: 'not_found#anything', via: [:get, :post]

要匹配通配符参数，必须为其分配一个名称 - 在本例中为 any。

class NotFoundController < ApplicationController
  def anything
    Logger.new('log/not_found.log').info(request.fullpath)
    # To render nothing:
    # head :not_found #Rails 5
    # render nothing: true, status: :not_found # for Rails 4

    #To render 404 page
    render file: 'public/404.html', status: :not_found, layout: false
  end
end

【解决方案2】：

您可以在所有其他可以捕获这些内容并呈现您选择的控制器/动作的路线之后添加一条全部捕获路线：

match '*' => 'errors#not_found'

您甚至可以选择仅匹配 .asp 或任何您想要的：

match '*.:format' => 'errors#not_found', :constraints => {:format => /(asp|zip|rar)/i}
