如何制作/ folder和/ folder / subfolder URL

Question

我是mod_rewrite的新手，并且想要执行以下操作：

创建website.com/[something with any character]目录，如果在链接中找到website.com/[something with any character]/，则将其重定向为不带“ /”的目录；到website.com/[something with any character]

另外，使website.com/[something with any character]/[something with any character]相同：如果检测到“ /”，请退出并重定向到website.com/[something with any character]/[something with any character]

我对此有麻烦，正在尝试但没有成功。

我有以下内容，当然，我错了：

RewriteEngine On

RewriteRule ^(.*)/$ /$1 [L,R=301]

RewriteCond %{REQUEST_URI} ^/([0-1a-zA-Z]+)?
RewriteCond %{REQUEST_URI} !^/([0-1a-zA-Z]+)/([0-1a-zA-Z]+)?
RewriteRule ^([0-1a-zA-Z]+) index.php?param=$1

RewriteCond %{REQUEST_URI} ^/([0-1a-zA-Z]+)/([0-1a-zA-Z]+)?
RewriteCond %{REQUEST_URI} !^/([0-1a-zA-Z]+)?
RewriteRule ^([0-1a-zA-Z]+)/([0-1a-zA-Z]+) index.php?param=$1&lang=$2
