如何基于.htaccess中的子域进行重定向？ .htaccess： 预期行为：

如果有子域test.example.com，它将转到文件夹/service/，如果没有，它将转到文件夹/site/

示例行为： 试试这些规则：

RewriteCond %{HTTP_HOST} !=www.example.com
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$
RewriteRule !^service/ service/index.php?id=%1 [L]

RewriteCond %{HTTP_HOST} =example.com
RewriteRule !^site/ site%{REQUEST_URL} [L]

test.example.com/post?id=2 -> public_html/service/post.php?id=1
test.example.com/category?id=3 -> public_html/service/category.php?id=3

example.com/register.php -> public_html/site/register.php

RewriteCond %{HTTP_HOST} !=www.example.com
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$
RewriteRule !^service/ service/index.php?id=%1 [L]

RewriteCond %{HTTP_HOST} =example.com
RewriteRule !^site/ site%{REQUEST_URL} [L]
