How to skip OPTIONS request in php-fpm in NGINX?

Question

PHP

Good afternoon, colleagues!

NGINX config setup question: how to make PUT, PATCH, HEAD, DELETE, OPTIONS and other requests, besides GET and POST, reach php-fpm?

Thanks for the help

upd1 : not interested in the answer of NGINX itself, like here . It is necessary that PHP see all these requests!
upd2 : cross-domain requests. For example, from test1.ru to api.domain.com
Solution : You cannot send requests other than GET/POST/HEAD to / host address.

You don't have to intentionally do anything to enable these methods, as they are available by default. Here's what to disable some methods, but you have to make an effort.
Let me give you an example to prove my point:

docker-compose.yml

version: '3'

services:
  alpine-nginx:
    image: nginx:stable-alpine
    container_name: alpine-nginx
    restart: "no"
    links:
      - composer-php
    volumes:
      - ./default.conf:/etc/nginx/conf.d/default.conf
      - ./code:/code
    ports:
      - "80:80"

  composer-php:
    image: php:7-fpm
    container_name: composer-php
    restart: "no"
    volumes:
      - ./code:/code
    ports:
      - "9000:9000"

default.conf

server {
  listen 80;
  listen [::]:80;

  client_max_body_size 2M;

  server_name domain.com admin.domain.com www.domain.com api.domain.com;

  charset utf-8;
  index index.php;

  root /code;

  gzip on;
  location / {
    try_files $uri $uri/ @phpindex;
  }

  location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass composer-php:9000;
    fastcgi_index index.php;
    include fastcgi_params;

    fastcgi_param   QUERY_STRING            $query_string;
    fastcgi_param   REQUEST_METHOD          $request_method;

  }
  location ~ /\.ht {
    deny  all;
  }
}

code/index.php

<?php

header('X-PHP-REQUEST_METHOD: ' . $_SERVER['REQUEST_METHOD']);

echo $_SERVER['REQUEST_METHOD'];

echo "\n\n"
?>

Answer 2

I found a needle in a haystack... Everything worked for me too. The difference is in the request URL. I sent all requests to / address. But it is impossible, apparently, to send requests other than GET POST and HEAD to /
I will consider yours as the correct answer, Alexander Karabanov , since I found a difference in your advice.
Thank you!
