.htaccess重写url显示找不到404

我想更改此URL

domain.com/adsbycat/sub_category.php?category=car-and-buses&category_id=1&sub_category=Car

到

我写这段代码就是为了做到这一点

RewriteEngine On  
RewriteBase /domain.com/    
RewriteRule ^adsbycat/([a-zA-Z0-9]+)/([a-zA-Z0-9]+)/([a-zA-Z0-9]+)$ adsbycat/sub_category.php?category=$1&category_id=$2&sub_category=$3

---

但是当我请求新的URL时，它显示404找不到。请修复此代码。

在site root.htaccess中具有此规则以重写

domain.com/car and bus/1/car

：

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/[^/]+/(.+)$ adsbycat/sub_category.php?category=$1&category_id=$2&sub_category=$3 [NC,L,QSA]

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/[^/]+/(.+)$ adsbycat/sub_category.php?category=$1&category_id=$2&sub_category=$3 [NC,L,QSA]
