Heroku 301重定向 [英] Heroku 301 Redirect

问题描述

我如何使 http://domain.com 301重定向到 http://www.domain.com ？我习惯使用.htaccess来ModRewrite它，但是我知道我不能在Heroku上这样做。

.htaccess的示例：

 选项+ FollowSymlinks 
 RewriteEngine在
 
 RewriteCond％{HTTP_HOST} ^ domain.com [NC] 
 RewriteRule ^（。*）$ http://www.domain.com/$1 [R = 301，L] 
  

我的文件结构：

   -  / public 
 --- / style 
 --- index.html 
  -  config.ru 
  

我只是提供单个页面和我的config.ru包含：

 使用Rack :: Static，
：url = > [/ style]，
：root => public
 
运行lambda {| env | 
 [
 200，
 {
'Content-Type'=> 'text / html'，
'Cache-Control'=> 'public，max-age = 86400'
}，
 File.open（'public / index.html'，File :: RDONLY）
] 
} 
  

解决方案

使用rack_rewrite（gem'rack-rewrite'一个rack_rewrite.rb在你的初始化程序目录中;

$ $ p $ YourAppName :: Application.config.middleware.insert_before（Rack :: Lock， Rack :: Rewrite）do
r301％r {。*}，'http：//www.yourdomainname.com$&'，：if => Proc.new {| rack_env |
rack_env ['SERVER_NAME']！='www.yourdomainname.com'
}
end if Rails.env =='production'


这就是说，如果被请求的服务器名称不是www.yourdomainname.com，那么将其重定向到www.yourdomainname.com。

How do I make it so http://domain.com 301 redirects to http://www.domain.com? I'm used to using .htaccess to ModRewrite it, but I've learned I can't do that on Heroku.

Example of .htaccess:

Options +FollowSymlinks
RewriteEngine On

RewriteCond %{HTTP_HOST} ^domain.com [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L]

My file structure:

- /public
--- /style
--- index.html
- config.ru

I'm just serving up the single page, and my config.ru consists of this:

use Rack::Static,
:urls => ["/style"],
:root => "public"

run lambda { |env|
[
200,
{
'Content-Type' => 'text/html',
'Cache-Control' => 'public, max-age=86400'
},
File.open('public/index.html', File::RDONLY)
]
} 

解决方案

use rack_rewrite (gem 'rack-rewrite' in your Gemfile) and create a rack_rewrite.rb in your initializers directory with;

YourAppName::Application.config.middleware.insert_before(Rack::Lock, Rack::Rewrite) do
  r301 %r{.*}, 'http://www.yourdomainname.com$&', :if => Proc.new {|rack_env|
    rack_env['SERVER_NAME'] != 'www.yourdomainname.com'
  }
end if Rails.env == 'production'

this says, if the servername being requested is not www.yourdomainname.com then redirect it to www.yourdomainname.com
