Rails - 确保 www 在 URL 中 [英] Rails - Ensuring www is in the URL

问题描述

我的应用程序托管在 Heroku 上，并且拥有 www.mysite.com 的证书

I have my app hosted on Heroku, and have a cert for www.mysite.com

我正在努力解决

• 确保 www 在 URL 中，并且 URL 是 HTTPS

这是我目前所拥有的:

class ApplicationController < ActionController::Base
before_filter :check_uri

  def check_uri
    redirect_to request.protocol + "www." + request.host_with_port + request.request_uri if !/^www/.match(request.host) if Rails.env == 'production'
  end

但这似乎不起作用.任何建议或可能不同的方法来解决以确保 HTTPs 和 www.在网址中吗?

But this doesn't seem to being working. Any suggestions or maybe different approaches to solve for ensuring HTTPs and www. is in the URL?

谢谢

推荐答案

对于 SSL，使用 rack-ssl.

For the SSL, use rack-ssl.

# config/environments/production.rb
MyApp::Application.configure do
  require 'rack/ssl'
  config.middleware.use Rack::SSL
  # the rest of the production config....
end

对于 WWW，创建您自己的机架中间件.

For the WWW, create a Rack middleware of your own.

# lib/rack/www.rb
class Rack::Www
  def initialize(app)
    @app = app
  end
  def call(env)
    if env['SERVER_NAME'] =~ /^www\./
      @app.call(env)
    else
      [ 307, { 'Location' => 'https://www.my-domain-name.com/' }, '' ]
    end
  end
end

# config/environments/production.rb
MyApp::Application.configure do
  config.middleware.use Rack::Www
  # the rest of the production config....
end

要在浏览器中进行测试，您可以在本地开发计算机上编辑 /etc/hosts 文件

To test this in the browser, you can edit your /etc/hosts file on your local development computer

# /etc/hosts
# ...
127.0.0.1 my-domain-name.com
127.0.0.1 www.my-domain-name.com

在本地开发计算机上以生产模式运行应用程序

run the application in production mode on your local development computer

$ RAILS_ENV=production rails s -p 80

然后浏览到 http://my-domain-name.com/ 看看会发生什么.

and browse to http://my-domain-name.com/ and see what happens.

在测试期间，您可能需要注释掉将您重定向到 HTTPS 站点的行.

For the duration of the test, you may want to comment out the line redirecting you to the HTTPS site.

也可以使用许多 Rails 项目使用的标准单元测试和集成测试工具来测试这一点，例如 Test::Unit 和 RSpec.

There may also be ways to test this with the standard unit-testing and integration-testing tools that many Rails projects use, such as Test::Unit and RSpec.
