Nginx request_uri without args

Question

How do I get the value of request_uri without the args appended on the end. I know there is a uri variable but I need the original value as the Nginx documentation states:

request_uri

This variable is equal to the original request URI as received from the client including the args. It cannot be modified. Look at $uri for the post-rewrite/altered URI. Does not include host name. Example: "/foo/bar.php?arg=baz"

Answer 1

I use this map, which works without lua:

map $request_uri $request_uri_path {
  "~^(?P<path>[^?]*)(\?.*)?$"  $path;
}
