当我为我的 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

并且,然后重复发出请求。请指导我找出这种行为的原因以及如何解决这个问题。

的输出rake:routes是:

您的应用没有到/app/update_progress. 因此,在您的应用程序中调用它是以下之一:

  1. 您的应用程序中的 Javascript 代码(您是否有机会使用此 Bootstrap 进度条?)

    要测试这是否是问题的根源 - 打开 Chrome 开发人员工具并转到网络面板。现在打开您的应用程序localhost:3000。如果您在此 Network 选项卡中看到对 的一致调用localhost:3000/app/update_progress,则表示您的应用程序正在从 Javascript 触发这些请求。现在您需要搜索您的代码库以找出该 javascript 代码的位置。它可能在您下载的一些 jquery 扩展中。每当/app/update_progress. _

  2. chrome/firefox 扩展

    要排除这种情况,请在隐身模式下打开 Chrome/Firefox(通常会禁用所有扩展),然后打开您的应用程序。如果您仍然看到点击,/app/update_progress那么很可能它不是导致问题的扩展。

  3. 您正在使用的一些外部 gem

    如果以上两个没有实现,请发布您的 Gemfile。

我不确定你的问题是什么。

当你启动你的服务器时,它会收到一个请求

http://127.0.0.1:3000/app/update-progress

但是该请求没有路由(Rails 不知道如何处理该请求),因此您会收到该错误。

要处理该请求,请添加一条路线:

match '/app/update-progress/' => 'some#action'

要了解有关请求的更多信息,请request从操作内部检查对象。
