使用通配符子域进行 Mod 重写？

发布于 2024-07-07 22:57:12 字数 141 浏览 8 评论 0原文

我打开了通配符子域，但是我只是不知道 mod_rewrite 达到编写此内容所需的程度。谁能告诉我如何制作它，以便除 www 之外的任何内容都不会进入主站点，但除此之外的任何子域都会进入 /script/index.php?username=$username ？

$username 变量应该来自哪里？

假设主站点的 URL 为 http://www.example.com/main_site.php 并且您正在使用此外部目录上下文（即不在 .htaccess 中也不在指令中）。如果它在 .htaccess 中，请删除前导 /（例如，将其设为 main_site.php）。

我认为这不会立即起作用，因为有许多不明确的变量（用户名从哪里来？，如何处理请求的其余部分，将其作为参数传递？，这是 htaccess 还是主配置？），但是希望能让你有一个想法：

#Turn on the rewrite engine
RewriteEngine On
#Check accessed domain, if it's either www.example.com or
RewriteCond %{HTTP_HOST} ^www.example.com$ [NC,OR]
#example.com
RewriteCond %{HTTP_HOST} ^example.com$ [NC]
#and the requested URL does not contain script you'll be accessing to avoid looping
RewriteCond %{REQUEST_URI} !main_site.php
#Then we tell that everything matching the above will go to main_site.php
RewriteRule ^ /main_site.php [L]
#If the request is not asking for main_site.php nor index.php
RewriteCond %{REQUEST_URI} !main_site.php
RewriteCond %{REQUEST_URI} !index.php
#We go to /script/index.php (username will be empty, becase we don't know 
#where to get it from)
RewriteRule ^ /script/index.php?username=$username [L]

Where does the $username variable supposed to come from??

Supposing the URL of the main site is http://www.example.com/main_site.php and that you are using this outside Directory context (ie, not in .htaccess nor in a <Directory> directive). If it is in .htaccess remove the leading / (make it just main_site.php, for example).

I reckon this will not work right away because there are many non clear variables (where does username come from?, what to do about the rest of the request, pass it as a parameter?, is this htaccess or main config?), but hopefully will get you an idea:

#Turn on the rewrite engine
RewriteEngine On
#Check accessed domain, if it's either www.example.com or
RewriteCond %{HTTP_HOST} ^www.example.com$ [NC,OR]
#example.com
RewriteCond %{HTTP_HOST} ^example.com$ [NC]
#and the requested URL does not contain script you'll be accessing to avoid looping
RewriteCond %{REQUEST_URI} !main_site.php
#Then we tell that everything matching the above will go to main_site.php
RewriteRule ^ /main_site.php [L]
#If the request is not asking for main_site.php nor index.php
RewriteCond %{REQUEST_URI} !main_site.php
RewriteCond %{REQUEST_URI} !index.php
#We go to /script/index.php (username will be empty, becase we don't know 
#where to get it from)
RewriteRule ^ /script/index.php?username=$username [L]
