如何使mod_rewrite的从子域名重定向到查询字符串？ [英] how to make mod_rewrite to redirect from subdomains to querystring?

问题描述

我想让mod-rewrite如下面的例子：

I want to make mod rewrite as the following example :

从google.com.mydomain.com到mydomain.com/index.php?domain=google.com

from google.com.mydomain.com to mydomain.com/index.php?domain=google.com

我使用像

RewriteCond %{HTTP_HOST} !^www [NC]
RewriteCond %{QUERY_STRING} !domain=
RewriteCond %{HTTP_HOST} ^([^\.]+)\.mydomain.com$ [NC]
RewriteRule ^(.*)$ /index.php?domain=%1 [L,QSA]

但这种重定向google.mydomain.com到mydomain.com/index.php?domain=google~~V

but this redirect google.mydomain.com to mydomain.com/index.php?domain=google

我要统治重定向google.com不是谷歌

I want rule to redirect google.com not google

感谢

推荐答案

这是由于不正确的正则表达式。试试这个规则：

It is due to the incorrect regex. Try this rule:

RewriteCond %{HTTP_HOST} !^www [NC]
RewriteCond %{QUERY_STRING} !domain=
RewriteCond %{HTTP_HOST} ^(.+?)\.mydomain\.com$ [NC]
RewriteRule ^(.*)$ /index.php?domain=%1 [L,QSA]

在您的规则你使用 [^ \\。] + 这匹配，直到点被发现，因此被匹配谷歌，而不是 google.com 。

In your rule you're using [^\.]+ which matched until a dot is found therefore it is matching google instead of google.com.
