如何在heroku上重定向域名？ [英] How do I redirect domains on heroku?

问题描述

我为stuff.heroku.com上的多个用户设计了一款应用程序。

I have an app designed for multiple users on stuff.heroku.com

着陆页可能类似stuff.heroku.com/controller/1/action/ 73

A landing page might look like stuff.heroku.com/controller/1/action/73

但是我想要在那里重定向的URL看起来像sub.domain.com/hello

But the URL that I want to redirect there looks like sub.domain.com/hello

，我可能希望sub.domain.com/greetings指向另一个登录页面，这次是stuff.heroku.com/controller/1/action/74。

Similarly, I may want sub.domain.com/greetings to point to another landing page, this time at stuff.heroku.com/controller/1/action/74.

一旦这个工作，我会希望sub.anotherdomain.com/hello映射回我的同一个应用程序，如stuff.heroku.com/controller/1/action/87

Once that works, I will want sub.anotherdomain.com/hello to map back to my same application, such as stuff.heroku.com/controller/1/action/87

我该怎么做？

推荐答案

您可以在application_controller中执行此操作，并在那里重定向。

You can do this in your application_controller and redirect there.

在Rails 2.3+中，您可以使用机架中间件。检查折射宝石 - 它被设置为mod_rewrite的机架替换品

In Rails 2.3+ you can use rack middleware. Check out the Refraction gem -- it's setup to be a rack replacement for mod_rewrite

https://github.com/pivotal/refraction

Refraction.configure do |request|
  if req.host == 'sub.domain.com'
    req.rewrite! "http://sub.domain.com/#{req.path}"
  end
end

以上只会将stuff.heroku.com中的用户引导至sub.domain.com - 但如果您愿意，您可以轻松完成/ hello重写。

The above will just take people from stuff.heroku.com to sub.domain.com -- but you could easily do your /hello rewrite if you want.
