Question

我已经创建了一个新的Rails应用程序。当我使用rails server命令在本地运行Rails应用程序时，将显示默认的“欢迎登机”页面。我已将此部署到Heroku，但是当我尝试访问Heroku应用程序时，收到The page you were looking for doesn't exist.消息。

为什么我没有收到默认的“欢迎登机”页面？

Answer 1

欢迎页面是公共文件夹中的默认index.html文件。

如果routes.rb文件中未指定root，则显示默认的index.html页面。

它在ngnix / apache服务上运行良好，但可能无法在heroku上运行。

如果你想显示一个页面然后创建一个控制器，例如HomeController并在views / home下添加文件index.html，并在route.rb中添加以下代码

public void test(int i=0,string s="")
    {
      // Function Body
    }

Answer 2

我认为类似的事情发生在我身上，你必须检查你的routes.rb文件，检查你是否有根路线，如：

# File: config/routes.rb
root "controller#action" #something like:  root "clients#index"

Heroku上的Rails应用程序不会显示“欢迎登机”页面
