Ask how to get the fastcgi cache key

The key of the fastcgi cache set in nginx.conf is as follows

fastcgi_cache_key $request_method://$host$request_uri;

For example, there is such a URL

http://levi.cg.am/archives/3066

How can I get the cached file name in PHP?

Note:

1. The purpose of this is to clear the Nginx cache of a page

2. I tried to write that, but it wasn't right.

   MD5 (' http://levi.cg.am/archives/3066 ');
