Question

I'm sending a POST request in Node.js to a php server. In the request i include the json as an object and not as a string.

Node.js request:

var request = require('request');

let data = { "name":"John", "age":30, "car":null };

request.post({
  headers: {'content-type' : 'application/json; charset=utf-8'},
  url: 'http://0.0.0.0:9000/html.php',
  method: 'POST',
  json: data
}, function(error, response, body){
  console.log(body);
});

html.php:

<?php
# Get JSON as an object
$json = file_get_contents('php://input');

$name = $json->name;

echo $json // Prints out the whole json correctly
echo $name; // Prints out "undefined"

I expect the output to be "John" instead of "undefined"

Answer 1

When you get the JSON, it comes to you as a string (as you proved with echo $json). To make it into an object you must decode it:

# Get JSON as an object
$json = file_get_contents('php://input');
$jsonObject = json_decode($json);

$name = $jsonObject->name;

echo $json // Prints out a string
echo $name;
