Setting up nginx, why is the request not being passed to php-fpm?

Question

Nginx

Good afternoon!
There is this config:

server {
        charset utf-8;
        client_max_body_size 128M;

        listen 80; ## listen for ipv4

        server_name tes.lc;
        root        /path/web;
        index       index.php;

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

        location ~* \.php$ {
                fastcgi_index   index.php;
                fastcgi_pass   unix:/var/run/php5-fpm.sock;
                include         fastcgi_params;
                fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
                fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
        }
}

and if you open the site, then it all works, but if you send a cross-domain request, then first a "preflight" OPTIONS request is sent and for some reason it does not come to php. Tell me how to be?

As for me, it's better to handle options by nginx itself, so as not to pull PHP once again
Instead of add_header 'Access-Control-Allow-Origin' "$http_origin"; in production, you need to hardcode the domain

if ($request_method = 'OPTIONS') {
      add_header 'Access-Control-Allow-Origin' "$http_origin";
      add_header 'Access-Control-Allow-Credentials' 'true';
      add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
      add_header 'Access-Control-Allow-Headers' 'Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Origin,Accept';
      add_header 'Content-Type' 'application/json';
      add_header 'Content-Length' 0;
 
      return 204;
    }
