Rewriting a query-string part as a path part using nginx?

Question

How do I rewrite URIs of the form

/one/two?path=three&foo=bar

to

/one/two/three?foo=bar

using nginx?

Answer 1

Try this:

location ~ /one/two {
    if ($args ~ "path=([^&]+)&(.+)") {
        set $path $1;
        set $foo $2;
        rewrite ^/one/two "/one/two/$path?$foo?" permanent;
    }
}
