Apache to Nginx rewrite rules

Question

I have Apache rules for a Web application that look like so:

RewriteEngine On RewriteRule ^unsubscribe/([-A-z0-9]+)/?(.*)$ /list/unsubscribe.php?id=$1&why=$2 [L,QSA] RewriteRule ^unsub/([-A-z0-9]+)/?(.*)$ /list/subscribe.php?id=$1&why=$2 [L,QSA] 

I've tried:

rewrite ^unsubscribe/([-A-z0-9]+)/?(.*)$ /list/unsubscribe.php?id=$1&why=$2; 

Which didn't seem to match and results in a 404.

 location /unsubscribe { rewrite ^/unsubscribe/([-A-z0-9]+)/?(.*)$ /list/unsubscribe.php?id=$1&why=$2 break; } 

Results in serving the file, but without PHP processed http://sg.hackandtell.org/unsubscribe/foo/bar

Perhaps can someone recommend some debug strategies?

Answer 1

I don't have a debug strategy, so I am not 100% sure what nginx is doing. Though I rewrote the rewrite rules like so:

rewrite ^/unsubscribe/([a-zA-Z0-9]*)$ /list/unsubscribe.php?id=$1; rewrite ^/unsub/([a-zA-Z0-9]*)$ /list/subscribe.php?id=$1; rewrite ^/unsubscribe/([a-zA-Z0-9]*)/(.*)$ /list/unsubscribe.php?id=$1&why=$2; rewrite ^/unsub/([a-zA-Z0-9]*)/(.*)$ /list/subscribe.php?id=$1&why=$2; 

And it works. :)

The nginx Wiki states:

last - completes processing of current rewrite directives and restarts the process (including rewriting) with a search for a match on the URI from all available locations.

break - completes processing of current rewrite directives and non-rewrite processing continues within the current location block only.

So when using break, it will use the server {...}-wide root directive (I assume you have one) and serve the file statically.

You should rather try last in your rewrite rule, because then the PHP-processing route will match in a second turn and direct the request to PHP.
