htaccess 仅在请求 uri 为空时重写

Question

我当前的 .htaccess 如下：

##FOR DUAL LEVEL TIER SUBDOMAIN
#SUBDOMAIN REWRITE for COUNTRY.CATEGORY.uqloo.com
RewriteCond %{HTTP_HOST} !www.mydomain.com$ [NC] # Presuming you don't want to do www
RewriteCond %{HTTP_HOST} ^(.*)\.(.*)\.mydomain\.com [NC] # Catch subdomain
RewriteCond %{REQUEST_URI} !\.(?:jpe?g|png|gif|bmp|php)$ [NC]
RewriteRule ^(.*)$ index.php?sub1=%1&sub2=%2 [QSA,L]

##FOR SINGLE LEVEL TIER SUBDOMAIN
RewriteCond %{HTTP_HOST} !www.mydomain.com$ [NC] # Presuming you don't want to do www
RewriteCond %{HTTP_HOST} ^(.*)\.mydomain\.com [NC] # Catch subdomain
RewriteCond %{REQUEST_URI} !\.(?:jpe?g|png|gif|bmp|php)$ [NC]
RewriteCond %{REQUEST_URI} !^cat/([A-Za-z0-9-]+)?$ [NC] # Don't rewrite if we already have
RewriteRule ^(.*)$ index.php?sub1=%1 [QSA,L]

我正在尝试仅进行单级和双级子域重定向，同时保持我对 URI 部分的所有其他重写。我想保持与子域相关的参数以及 URI 重写。

一个例子是以下规则不断被重定向回 index.php，当它应该转到 pages/details.php 时，如果子域是可用的参数 sub1 和 sub2现在。

RewriteRule ^([0-9-]+)?/([A-Za-z0-9-]+)?$

pages/details.php?adid=$1&alias=$2 [NC,L]

Answer 1

您可以使用这些规则：

RewriteEngine On

# pages URL handlers
RewriteCond %{HTTP_HOST} ^(?!www\.)([^.]+)\.mydomain\.com$ [NC]
RewriteRule ^([0-9-]+)/([a-z0-9-]+)/?$ pages/details.php?sub1=%1&adid=$1&alias=$2 [NC,L,QSA]

RewriteCond %{HTTP_HOST} ^(?!www\.)([^.]+)\.([^.]+)\.mydomain\.com$ [NC]
RewriteRule ^([0-9-]+)/([a-z0-9-]+)/?$ pages/details.php?sub1=%1&sub2=%2&adid=$1&alias=$2 [NC,L,QSA]

# subdomain rewrites
RewriteCond %{REQUEST_URI} !\.(?:jpe?g|png|gif|bmp|php)$ [NC]
RewriteCond %{REQUEST_URI} !^/cat/([A-Za-z0-9-]+)?$ [NC]
RewriteCond %{HTTP_HOST} ^(?!www\.)([^.]+)\.mydomain\.com$ [NC]
RewriteRule ^ index.php?sub1=%1 [QSA,L]

RewriteCond %{REQUEST_URI} !\.(?:jpe?g|png|gif|bmp|php)$ [NC]
RewriteCond %{HTTP_HOST} ^(?!www\.)([^.]+)\.([^.]+)\.mydomain\.com$ [NC]
RewriteRule ^ index.php?sub1=%1&sub2=%2 [QSA,L]
