如何用 .htaccess 重写子域？

Question

我有一个这样的子域：

Example: http://us.example.com/index.php?city=newyork

我该如何重写：

http://us.example.com/newyork

“us”是一个虚拟子域。所以，它可以是不同的：我们、fr、it 等等。

我用这种方法试过了，但是不行

RewriteEngine on

RewriteCond %{HTTP_HOST} !^example\.com
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*) index.php?city=$1

保持这样：

RewriteEngine on

# external redirect from actual URL to pretty one
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^[^.]+\.example\.com$ [NC]
RewriteCond %{THE_REQUEST} \s/+index\.php\?city=([^\s&]+) [NC]
RewriteRule ^ /%1? [R=302,L]

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^[^.]+\.example\.com$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/?$ /index.php?city=$1 [L,QSA]

编辑：

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^[^.]+\.example\.com$ [NC]
RewriteCond %{THE_REQUEST} \s/+index\.php\?city=([^&]+)&ountry=([^\s&]*)\s [NC]
RewriteRule ^ /%1/%2? [R=302,L]

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^[^.]+\.example\.com$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/([^/]+)/?$ /index.php?city=$1&country=$2 [L,QSA]
