Rails手动从裸域重定向

问题描述

所以目前，由于我的托管服务提供商（Heroku）的限制，我是从裸体域手动指导的。一切都很好。问题是，如果用户访问mydomain.com/route，将重新发送回www.mydomain.com而不使用/ route。我如何去重新添加路线，但仍然重定向到www。 ？

So currently I am manually directing from a naked domain due to restrictions with my hosting provider (Heroku). Everything works just fine. The problem is that if a users visits mydomain.com/route, a redirect will be issued back to www.mydomain.com without the /route. How would I go about re-appending the route, but still redirecting to www. ?

class ApplicationController < ActionController::Base
protect_from_forgery
before_filter :ensure_domain
APP_DOMAIN = 'www.domain.com'
def index
end
def ensure_domain
    if Rails.env.production?
        if request.env['HTTP_HOST'] != APP_DOMAIN
            redirect_to "http://#{APP_DOMAIN}", :status => 301
        end
    end
end
end

编辑

我从我的ApplicationController中删除了我的代码，并选择使用，由hurikhan77提出，解决了我的问题。

I removed my code above from my ApplicationController, and opted for using the refraction gem as suggested by hurikhan77, which solved my problem.

这里是refraction_rules.rb我使用的。 / p>

Here is refraction_rules.rb I used.

Refraction.configure do |req|
  if req.host == "domain.com"
    req.permanent! :host => "www.domain.com"
  end
end
