重定向到trailng斜杠（htaccess）

Question

尝试为每个链接添加尾部斜杠。例如：

http://testsite.com/products 

301 redirect应该：

http://testsite.com/products/ 

等。但是怎么样？这是我目前的.htaccess：

AddDefaultCharset utf-8
Options -Indexes

RewriteEngine On
RewriteBase /
RewriteRule ^.htaccess$ - [F]

RewriteCond %{REQUEST_URI} !\.(ico|css|js|txt)$ [NC]
RewriteCond %{REQUEST_FILENAME} !^/admin
RewriteCond %{REQUEST_FILENAME} !^/migrate
RewriteCond %{REQUEST_FILENAME} !^/install
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.*)$ /index.php [L]

Answer 1

 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteRule ^(.*[^/])$ /$1/ [L,R=301]
