.htaccess重写:子域为GET var,路径为GET var


.htaccess rewrite: subdomain as GET var and path as GET var

所需结果:

http://example.com/                 -> index.php
http://www.example.com/             -> index.php
http://hello.example.com/           -> index.php?subdomain=hello
http://whatever.example.com/        -> index.php?subdomain=whatever
http://example.com/world            -> index.php?path=world
http://example.com/world/test       -> index.php?path=world/test
http://hello.example.com/world/test -> index.php?subdomain=hello&path=world/test

使用我现在拥有的.htaccess,我可以实现其中一个或另一个重新映射,但不能同时实现这两个。

RewriteEngine On
# Parse the subdomain as a variable we can access in PHP, and
# run the main index.php script
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{HTTP_HOST}        !^www
RewriteCond %{HTTP_HOST}         ^([^'.]+)'.([^'.]+)'.([^'.]+)$
RewriteRule ^.*$ index.php?subdomain=%1
# Map all requests to the 'path' get variable in index.php
RewriteBase /
RewriteRule ^index'.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?path=$1 [L] 

我很难把两者结合起来。。。有什么建议吗?

编辑
我现在遇到的不想要的行为是,如果我有一个子域和.com/之后的路径,那么只有子域会通过,即:

http://hello.example.com/world-> index.php?subdomain=hello

使用第一条规则添加subdomain参数,而不更改URI,然后使用第二条规则将URI路由到index.php:

RewriteEngine On
# Parse the subdomain as a variable we can access in PHP, and
# run the main index.php script
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{HTTP_HOST}        !^www
RewriteCond %{HTTP_HOST}         ^([^'.]+)'.([^'.]+)'.([^'.]+)$
RewriteRule ^(.*)$ /$1?subdomain=%1
# Map all requests to the 'path' get variable in index.php
RewriteRule ^index'.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?path=$1 [L,QSA] 

第二个规则需要具有QSA标志,否则第一个规则的查询字符串将丢失。
