htaccess 子域到页面的重写规则 [英] htaccess Rewrite Rule for subdomain to page

问题描述

目前我有一个页面位于:

Currently I have a page residing at:

http://www.example.com/site/page

在我的 htaccess 中，我有当前的规则:

In my htaccess I have the current rule:

RewriteRule ^site/(.*)$ retailer.php?linklabel=$1 [QSA]

让该页面的 URL 成为它自己的子域的规则是什么样的:

What would the rule look like to have the URL for that page become it's own subdomain:

http://page.example.com

感谢您的帮助！！

到目前为止，我已经尝试了以下规则，但没有奏效:

So far I have tried the following rule which hasn't worked:

RewriteRule http://(.*)$.example.com retailer.php?linklabel=$1 [QSA]

也许我需要先在 cpanel 中做一些关于通配符子域的事情?我不太确定...

Maybe I need to do something in cpanel first regarding a wildcard subdomain? I'm not too sure...

推荐答案

尝试:

RewriteCond %{HTTP_HOST} !^www.[NC]
RewriteCond %{HTTP_HOST} ^(.+?).example.com$ [NC]
RewriteRule ^$ retailer.php?linklabel=%1 [L,QSA]

你不能在 RewriteRule 中匹配主机，所以你需要在 RewriteCond 中匹配 %{HTTP_HOST} 变量，然后使用 %1 反向引用来获得匹配.

You can't match against the host in a RewriteRule, so you'll need to do it against the %{HTTP_HOST} var in a RewriteCond, then use the %1 backreference to get that match.

目前这只会匹配完全是 / 的 URI.所以它不会与 http://page.example.com/something 匹配，除非你将正则表达式从 ^$ 更改为 ^something$.

This will currently only match against URI's that are exactly /. So it won't match against http://page.example.com/something unless you change the regular express at from ^$ to ^something$.
