.htaccess 友好的 URL

Question

有人可以帮我重写一些 URL 吗？

我有:
(例子)

www.example.com/index.php?page=namepage
www.example.com/index.php?page=gallery&topic=nametopic
www.example.com/index.php?page=homepage&paging=1

我想拥有:

www.example.com/namepage
www.example.com/gallery/nametopic
www.example.com/homepage/1

我的 htaccess 文件中有:

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/?$ ?page=$1 [L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/([^/]+)?/?$ ?page=$1&topic=$2

但效果不是很好，因为我可以写:

www.example.com/index.php?page=namepage(页面或其他)

www.example.com/?page=namepage(页面或其他)

www.example.com/namepage/

www.example.com/namepage(这是我想要的 - 没有其他)

第二个问题是:

www.example.com/namepage(好吧，我想要，我们看到了姓名页)

www.example.com/namepage/whatever(不行，我想要 404，但我们看到了名称页)

www.example.com/gallery/topic(好吧，我想要，我们看到nametopic)

www.example.com/whatever/whatever2/whatever3(好吧，我想要 404)

非常感谢任何人。

### all your redirects

# for www.example.com/index.php?page=homepage&paging=1
RewriteCond %{THE_REQUEST} \?page=([^&]+)&paging=([0-9]+)
RewriteRule ^ /%1/%2? [L,R=301]

# for www.example.com/index.php?page=gallery&topic=nametopic
RewriteCond %{THE_REQUEST} \?page=([^&]+)&topic=([^&\ ]+)
RewriteRule ^ /%1/%2? [L,R=301]

# for www.example.com/index.php?page=namepage
RewriteCond %{THE_REQUEST} \?page=([^&\ ]+)($|\ )
RewriteRule ^ /%1? [L,R=301]

# for www.example.com/namepage/
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)/$ /$1 [L,R=301]

### all your rewrites back

RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/([0-9]+)$ /index.php?page=$1&paging=$2 [L]

RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/([^/]+)$ /index.php?page=$1&topic=$2 [L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)$ /index.php?page=$1 [L]
