Redirect removing sufixes after 3 URL segmentes in Nginx

Question

This is the URL that I need to remove the last segment (?order=asc)

https://www.example.com/segment_1/segment_2/page/the_number_goes_here/?order?asc

This is the code I'm trying:

location ~ ^/([^/]+)/([^/]+)/page/(\d+)/ {
    try_files $uri $uri/ /index.php?$args;
    # Capture the 2 segments and page number
    set $segment_1 $1;
    set $segment_2 $2;
    set $page_number $4;
    # Redirect without the sufix
    rewrite ^ /$segment_1/$segment_2/page/$page_number/ permanent;
}

Answer 1

The location and rewrite directives process the normalised URI which does not include the query string (which you have called "the last segment").

The query string is available in the $args variable.

The rewrite directive can optionally remove the original query string by appending a ? to the end of the replacement value.

For example:

rewrite ^ /$segment_1/$segment_2/page/$page_number/? permanent;

Also, in your example code:

• The page number is captured in $3 and not $4
• The try_files statement is probably redundant as Nginx will always evaluate the set and rewrite directives first.

is evaluated first
