Nginx重写将jpg解析为php

Question

I'm converting from Apache to Nginx and I hit a tricky rewrite rule. Here is a sample link:

/cats/Parameter_1/Parameter_2.jpg

I'm matching "Paramter_1" and "Parameter_2" then ignoring the ".jpg" file extension. This worked just fine in Apache.

Here is the original Apache Rewrite rule:

RewriteRule ^cats/([-a-zA-Z0-9_]*)/([-a-zA-Z0-9_]*) /includes/cats/fan/001.php?Parameter_1=$1&Parameter_2=$2 [L]

This is the non-working Nginx rewrite that I made:

rewrite ^/cats/([-a-zA-Z0-9_]*)/([-a-zA-Z0-9_]*) /includes/cats/fan/001.php?Parameter_1=$1&Parameter_2=$2 last;

I have converted two other rewrites using this pattern. What makes this different is that the link ends in ".jpg" and I think Nginx doesn't know to parse this as a php file.

Do any of you more experienced folks have an idea how I can get this to work?
