Question

我的路线如下：

Rails.application.routes.draw do
  get 'courses' => 'application#index'
  get 'check_db' => 'application#check_db'

  root 'application#index'
end

我的application#check_db是

def check_db
  p "test"
  redirect_to root_path
end

当我在浏览器上访问/check_db时（在Chrome和Safari中都尝试过），如果工作正常，则应GET "/check_db"然后GET "/"。但实际上，日志显示有四个请求，上述模式重复两次（即GET "/check_db"，GET "/"，GET "/check_db"，GET "/"）。我的application#index中绝对没有任何代码可以执行任何其他重定向。那为什么会这样？

上述情况大多数时间都会发生。但是，偶尔会按预期工作。我没有在过渡期间更改代码。

如果感兴趣，则将整个日志粘贴在下面：

Rails在一个请求上接收重复请求
