Nginx Try_files redirection losing query string - php

Question

I am trying to setup a specific redirection to force redirection to index.php (for Laravel) for a specific subdirectory, bypassing existing index.html.
The url i want to catch looks like this app/kit//?email= . In each directory there's a index.html file (and for some business reasons it's hard to change this)
The redirection seems to work, but when i parse $_SERVER in index.php, i lose the query string.
My Nginx configuration look like this:
server {
server_name somedomain.com;
root /home/www/preprod/current/public/;
rewrite_log on;
access_log /var/log/nginx/preprod-access.log;
error_log /var/log/nginx/preprod-error.log notice;
location ~* /kit/(.*)/index\.html {
error_log /var/log/nginx/preprod-kit-error.log debug;
try_files /index.php?$query_string /dev/null;
}
location / {
index index.php index.html;
try_files $uri $uri/ /index.php?$query_string;
client_max_body_size 0;
autoindex off;
allow all;
}
location ~ \.php$ {
error_log /var/log/nginx/preprod-php-error.log debug;
#try_files $uri =404;
#fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_intercept_errors off;
fastcgi_connect_timeout 300s;
fastcgi_read_timeout 15m;
fastcgi_send_timeout 600s;
fastcgi_keep_conn on;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi_params;
client_max_body_size 0;
include snippets/fastcgi-php.conf;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
All the application works fine, except this one.
Edit 1: snippets/fastcgi-php.conf
# regex to split $uri to $fastcgi_script_name and $fastcgi_path
fastcgi_split_path_info ^(.+\.php)(/.+)$;
# Check that the PHP script exists before passing it
try_files $fastcgi_script_name =404;
# Bypass the fact that try_files resets $fastcgi_path_info
# see: http://trac.nginx.org/nginx/ticket/321
set $path_info $fastcgi_path_info;
fastcgi_param PATH_INFO $path_info;
#fastcgi_index index.php;
include fastcgi.conf;

I found a solution,i used this :
location ~* /kit/(.*)/(.*) {
error_log /var/log/nginx/preprod.adsconsole.com-kit-error.log debug;
rewrite /kit/(.*)/(.*) /index.php$is_args$args;
}
The regexp can obviously be better written, but if it can help someone !
