我如何使用子目录而不是子域？

问题描述

我正在构建一个rails应用程序，我将在domain.com上的Heroku上进行托管。而且我想在托管在phpfog上的博客中使用WordPress，但我不想使用像blog.domain.com这样的子域。我宁愿使用像domain.com/blog这样的子目录

它不是关于SEO ......我只是不喜欢子域名迷。子目录更性感（是的...我实际上是这么说的）。

关于我如何可靠地完成此任务的任何想法？您可以使用。首先，您需要添加 gemrack-reverse-proxy，：require => rack / reverse_proxy到您的Gemfile并运行 bundle install 。接下来，您将修改 config.ru 以将 / blog / 路线转发到您所需的博客：

  require :: File.expand_path（'../ config / environment'，__FILE__）
 
 use Rack :: ReverseProxy do 
 reverse_proxy /^\/blog(\/.*)$/，'http：//notch.tumblr.com$1'，opts = {：preserve_host => true} 
 end 
 
 run YourAppName :: Application 
  

您可能已经有第一个require语句，运行YourAppName ... 语句。有几个重要的细节使这项工作。

首先，当您添加所需的博客网址时，无法保留最后的斜杠。如果是这样，当有人请求 http://yourdomain.com/blog/ 时，gem会将它们转发给 http：//you.yourbloghost .com // ，并带有一个额外的斜线。第二，如果：preserve_host 选项未启用，您的博客托管服务器将看到请求为为 http://yourdomain.com/blog/ 而不是 http://you.yourbloghost.com 和会返回不好的结果。

如果博客使用 / absolute / paths / to / images / 。

I'm building a rails app that I'll host on Heroku at domain.com. And I'd like to use WordPress for the blog hosted on phpfog, but I don't want to use a subdomain like blog.domain.com. I'd instead prefer to use a subdirectory like domain.com/blog

Its not about SEO...I'm just not a fan of subdomains. Subdirectories are sexier (yeah...I actually said that).

Any idea on how I can reliably accomplish this? Thanks in advance for the help.

解决方案

You can use the rack-reverse-proxy gem that neezer found to do this. First you'll want to add gem "rack-reverse-proxy", :require => "rack/reverse_proxy" to your Gemfile and run bundle install. Next, you'll modify your config.ru to forward the /blog/ route to your desired blog:

require ::File.expand_path('../config/environment',  __FILE__)

use Rack::ReverseProxy do
       reverse_proxy /^\/blog(\/.*)$/, 'http://notch.tumblr.com$1', opts={:preserve_host => true}
end

run YourAppName::Application

You probably already have the first require statement and the run YourAppName... statement. There are a couple important details that make this work.

First, when you add your desired blog URL, you can't keep the trailing slash on it. If you do, when someone requests http://yourdomain.com/blog/, the gem will forward them to http://you.yourbloghost.com// with an extra trailing slash.

Secondly, if the :preserve_host option isn't enabled, your blog hosting server will see the request as being for http://yourdomain.com/blog/ instead of as http://you.yourbloghost.com and will return bad results.

You still may have an issue with the CSS or images if the blog uses /absolute/paths/to/images/.
