Cannot find post paramaters in php

Question

I am using fetch in react native application to send a post request as:

const data = {
    name: 'name',
    email: 'email'
  }
try{
    var r = await fetch(SEND_INITIAL_DATA, {
      method: 'POST',
      body: JSON.stringify(data),
      headers:{
       'Content-Type': 'application/json'
      }
    });
  }catch(err){
    console.log(err);
  }
  console.log(r);

I am using php in my backend server. but I am unable to access the parameters in php and printing the $_POST is missing body

PHP :

<?php
require 'connect.php';

echo json_decode($_POST); // printing the post

RESPONE

What am I missing ?

It's better to use then and catch in fetch for better debugging. example:

fetch('http://example.com/movies.json')
  .then(function(response) {
    return response.json();
  })
  .then(function(myJson) {
    console.log(myJson);
  });

Reference: https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch

Change your code to:

const data = {
    name: 'name',
    email: 'email'
}

    await fetch(SEND_INITIAL_DATA, {
            method: 'POST',
            body: JSON.stringify(data),
            headers: {
                'Content-Type': 'application/json'
            }
        }).then(function(response) {
            return response.json();
        })
        .then(function(myJson) {
            console.warn(myJson);
        });

If you have an error, it will be printed and you can debug it.
