Nginx rewrite path to query string

Question

I use nginx (php-fpm) and fatfree framework. I need some redirect logic in my routing engine. It looks like:

http://example.net/page/...

Instead of dots there could be something like:

another.net/someurl
http://another.net/?local_query
another.net/path/to/article.html

It breaks nginx logic and I see 404 error.

My nginx config looks simply:

location / {
    try_files           $uri    $uri/    /index.php?$args;
}

location ~ \.php$ {
    include             /etc/nginx/conf.d/fastcgi_params.conf;

    fastcgi_param       SCRIPT_FILENAME     /var/www/$main_host/www$fastcgi_script_name;
    fastcgi_param       DOCUMENT_ROOT       /var/www/$main_host/www;

    fastcgi_param       PHP_ADMIN_VALUE     upload_tmp_dir=/var/www/$main_host/tmp/upload;
    fastcgi_param       PHP_ADMIN_VALUE     session.save_path=/var/www/$main_host/tmp/sessions;
}

So when I use:

http://example.net/page/another.net/path/to/article.html

Nginx tries to find file in filesystem with name article.html as I understand. How to write rule to ignore any symbols when there is keyword page after domain?

use another location block, like location ~ /page/

Solution #1:

Probably it doesn't work because there is no fastcgi_pass directive inside /etc/nginx/conf.d/fastcgi_params.conf.

If so, all you need is simply add it to your \.php$ location. In general case it looks like:

fastcgi_pass 127.0.0.1:9000;

but this line might be different, depending on how PHP-FPM is configured.

Solution #2:

Your current configuration makes Nginx pass request to PHP-FPM only if URI ends with .php.

To make Nginx do it when URI starts with /page/ as well, you should write a new location with almost the same content (except for SCRIPT_FILENAME line) and (important!) put it before existing \.php$ location.

Copying location content would cause a code duplication, and I would recommend write the config in a slightly different way:

fastcgi_param       SCRIPT_FILENAME     /var/www/$main_host/www$my_script_name;
fastcgi_param       DOCUMENT_ROOT       /var/www/$main_host/www;

fastcgi_param       PHP_ADMIN_VALUE     upload_tmp_dir=/var/www/$main_host/tmp/upload;
fastcgi_param       PHP_ADMIN_VALUE     session.save_path=/var/www/$main_host/tmp/sessions;
include             /etc/nginx/conf.d/fastcgi_params.conf;

location ~ /page/ {
    fastcgi_pass 127.0.0.1:9000;
    set $my_script_name /path/to/file.php;
}

location ~ \.php$ {
    fastcgi_pass 127.0.0.1:9000;
    set $my_script_name $fastcgi_script_name;
}

In this case you will have 2 scenarios:

if URI starts with /page/, Nginx will run /var/www/$main_host/www/path/to/file.php.
if URI ends with .php, Nginx will run requested php file, as usual.

Solution #3:

Leave your \.php$ location as is and put the following location before it:

location ~ ^/page/ {
    include             /etc/nginx/conf.d/fastcgi_params.conf;

    fastcgi_param       SCRIPT_FILENAME     /var/www/$main_host/www/path/to/file.php;
    fastcgi_param       DOCUMENT_ROOT       /var/www/$main_host/www;

    fastcgi_param       PHP_ADMIN_VALUE     upload_tmp_dir=/var/www/$main_host/tmp/upload;
    fastcgi_param       PHP_ADMIN_VALUE     session.save_path=/var/www/$main_host/tmp/sessions;
}

Just replace /path/to/file.php with real path to file which should handle such requests.

Thank you for the answer. When I put fastcgi_pass into any location I see an error:

nginx: [emerg] "fastcgi_pass" directive is duplicate in /etc/nginx/conf.d/fastcgi_params.conf: nginx: configuration file /etc/nginx/nginx.conf test failed

@Ockonal do you have other locations along with those two you posted in the question?

@Ockonal take a look at the Solution 3

Max Frai Over a year ago

thank you, it works in case of: http://example.com/page/foo/bar but fails when: http://example.com/page/foo/bar.html (404)

Oleg Over a year ago

@Ockonal it looks like there is another location before that I posted, which intercepts .html request. If it is so, you may try put ^/page/ location before any other location
