被困在301重定向与变量php - Stuck on 301 redirect with variables php

我正试图在.htaccess文件中写一个301，但无法使其工作。我们有如下网址…

http://www.example.com/?cat=tree-category
http://www.example.com/?cat=food-category

我们想将这些更改为

http://www.example.com/directory/listings/tree-category
http://www.example.com/directory/listings/food-category

有人能帮忙吗？我将不胜感激！

James

这应该做到：

RewriteEngine On
RewriteCond %{REQUEST_URI}  ^/$
RewriteCond %{QUERY_STRING} ^cat=([a-zA-Z0-9'-]*)$
RewriteRule ^(.*)$ http://www.example.com/directory/listings/%1 [R=301,L]
