How to accept POST json request in php?

Question

PHP

Hello! There was a question with which I am excruciated already some days.
There is a service that sends a request in json format to the specified POST page, but I need to catch it on my page and add elements to the database.
The documentation says:
Request example:

POST /page.php HTTP/1.1
Host: host.host
Authorization: Bearer XXXXX
Content-Type: application/json
Accept: application/json
Cache-Control: no-cache
{
"date": "2017-04-25T01:29:20.4520214+00:00",
"stocks": [
    {
    "nnt": 111173,
    "qnt": 5,
    "man": "man",
    "prcRet": 117.99,
    "name": "name",
    "dtComing": "2017-08-09T00:00:00 + 07:00"
    }
 ]
}

Example of a successful response:

HTTP/1.1 202 Accepted
[]

I'm trying to catch via php

header('content-type: application/json');
$v = json_decode(file_get_contents('php://input'));
echo json_encode($v);

But on the page I get NULL, although the service says that everything is good. Can you please tell me how to get this json?

Answer 1

$_POST?

parsiphp://input

$input = json_decode(file_get_contents("php://input"), true);

If it is empty, then go further along the chain: https://php.net/manual/en/wrappers.php.php
Go through and find everything that flies to you.
