ruby-on-rails – 来自Rails app的Enigmatic GET请求

概述当我为Rails应用程序运行服务器时,我看到了一件奇怪的事情.这是日志： Jatins-MacBook-Pro: silverSpoon$rails s=> Booting Thin=> Rails 3.2.8 application starting in development on http://0.0.0.0:3000=> Call with -d to detach=> Ctrl 当我为Rails应用程序运行服务器时,我看到了一件奇怪的事情.这是日志：

然后,请求反复进行.请指导我找到此类行为的原因以及如何解决此问题.

rake：routes的输出是：

解决方法 您的应用没有到/ app / update_progress的路线.所以它是下面的一个在你的应用程序中调用它：

>你的应用程序中的JavaScript代码(你有机会使用this Bootstrap Progressbar吗？)

要测试这是否是问题的根源 – 打开Chrome开发者工具并转到Network panel.现在打开您的应用程序localhost：3000.如果您在此网络选项卡中看到对localhost：3000 / app / update_progress的一致调用,则表示您的应用程序正在从JavaScript触发这些请求.现在,您需要搜索代码库以找出JavaScript代码的位置.它可能在你已下载的某个jquery扩展中.你可以create a breakpoint in Javascript whenever an Ajax request is made到/ app / update_progress.
> Chrome / firefox扩展

要解决此问题,请以隐身模式打开Chrome / firefox(通常会禁用所有扩展程序),然后打开您的应用程序.如果您仍然看到/ app / update_progress的匹配,那么很可能它不是导致问题的扩展.
>你正在使用的一些外部宝石

如果上面两个没有实现,那么发布您的Gemfile.
