.htaccess mod_用1或2个参数重写url

URL:

http://example.com/good_game/osmp/

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/([^/]+)/?$ /?service=$1&terminal=$2 [L,QSA]

我收到

Array ( [service] => good_game [terminal] => osmp )

没关系，但是

URL:

http://example.com/good_game

或

http://example.com/good_game/

我需要

Array ( [service] => good_game)

---

它返回404 not found

这应该适用于以下两种情况：

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]*|)/?([^/]*|)/?$ /?service=$1&terminal=$2 [L,QSA]

将匹配：

http://example.com/good_game/osmp/
http://example.com/good_game/osmp
http://example.com/good_game/
http://example.com/good_game
