transfer rewrite rule from apache to nginx

Question

I have a problem with two rewrites transfering a sito from an apache hosting to an nginx hosting. I've tried reading online, this is the best that i've come up with, unfortunately I have little practice with regexp and rewrites on nginx, please help.

apache rewrite

RewriteRule ^news/([^/]+)/([^/]+)/([^/]+)\.html$    news_dett.php?l=$1&par=$2&titolo=$3 [L]

result apache

exampleSite/news/it/44/Title_Of_the_news.html

apache rewrite

RewriteRule ^Research-and-develop\.html$     researchdevelop?l=$1 [L]

result apache

exampleSite/Research-and-develop.html

nginx rewrite

location /news {
     rewrite ^/news http://$http_host/news_dett.php?l=$1&par=$2&titolo=$3 redirect;
    }

result nginx

Clicking on link exampleSite/news/it/44/Title_Of_the_news.html we go to exampleSite/news_dett.php?l=&par=&titolo=

In fact this doesn't work at all

nginx rewrite

location /Research {
            rewrite ^/Research-and-develop\.html$ http://$http_host/researchdevelop?l=$1 redirect;
    }

result nginx

clicking on link exampleSite/Research-and-develop.html we go to exampleSite/researchdevelop.php?l=

Can you help set the correct rewrite mode for nginx?

Answer 1

Your /news rewrite is missing the captures for $1 and $2 . The scheme and server parts are unnecessary when redirecting to the same server. Also, last performs an internal redirect, which avoids exposing the rewrite to the customer. It should look like this:

rewrite ^/news/([^/]+)/([^/]+)/([^/]+)\.html$ /news_dett.php?l=$1&par=$2&titolo=$3 last;

Optionally placed inside a location /news { ... } block.

It is not clear from your question as to the value of $1 in the second rewrite rule (I am assuming that it is empty). An alternative to an exact match rewrite directive would be an exact match location:

location = /Research-and-develop.html {
    rewrite ^ /researchdevelop?l= last;
}
