在重写规则重用子域 [英] Reuse subdomain in a rewrite rule

问题描述

我有点坚持我的重定向规则。小例子比长篇演说更好，在这里不用大丑：

I'm a bit stuck with my redirect rule. Little example better than a long speech, here goes the Great Ugliness:

IndexIgnore *
ErrorDocument 404 http://www.example.com
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.  [NC]
RewriteRule ^([^\.]+)\.example\.com$ http://example.com/private/$1/public/si.php  [L]

我的目标是让子域（[^ \。] +），并用它在重定向，而不​​是 $ 1 。 例如， test.example.com 应重定向到 http://example.com/private/test/public/si.php

My objective is to get the subdomain ([^\.]+) and use it in the redirection instead of $1. For example, test.example.com should redirect to http://example.com/private/test/public/si.php

感谢您的任何帮助。

问候， 秒。

最终工作htaccess的：

final working htaccess:

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.  [NC]
RewriteCond %{REQUEST_URI} !^/private/
RewriteCond %{HTTP_HOST} ([^\.]+).example.com [NC]
RewriteRule ^ /private/%1/public/$1  [R=301,L]

重定向 anysub.example.com/anypage 到 anysub.example.com/private/anysub/public/anypage

推荐答案

用于匹配的模式的重写规则将从来没有的字符串包含主机名，仅URI和没有任何查询字符串。如果你忽略实际URI是什么，那么你并不需要在重写规则模式匹配任何东西。你需要使用的％符号反向引用一个previous在一个分组的RewriteCond

The string used to match against the pattern of a RewriteRule will never contain the hostname, only the URI and without any query string. If you are to ignore what the actual URI is, then you don't need a pattern in the RewriteRule to match anything. You'd need to use a % symbol to backreference a previous grouping in a RewriteCond

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$ [NC]
RewriteRule ^ http://example.com/private/%1/public/si.php [L]

您可以在规则的方括号中添加 R = 301 标志，使永久重定向

You can add a R=301 flag in the rule's square brackets to make the redirect permanent.
