Send Post request to Node.js with PHP cURL

If your body simply contains a stringified version of the JSON blob, then replace

var json = qs.stringify(fullBody);

With

var json = JSON.parse(fullBody);

You're using querystring.stringify() incorrectly. See the documentation on querystring's methods here:

http://nodejs.org/docs/v0.4.12/api/querystring.html

I believe what you want is something like JSON.stringify() or querystring.parse(), as opposed to querystring.stringify() which is supposed to serialize an existing object into a query string; which is the opposite of what you are trying to do.

What you want is something that will convert your fullBody string into a JSON object.

try this code

<?php$data = array(    'username' => 'tecadmin',    'password' => '012345678'); $payload = json_encode($data); // Prepare new cURL resource$ch = curl_init('https://api.example.com');curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);curl_setopt($ch, CURLINFO_HEADER_OUT, true);curl_setopt($ch, CURLOPT_POST, true);curl_setopt($ch, CURLOPT_POSTFIELDS, $payload); // Set HTTP Header for POST request curl_setopt($ch, CURLOPT_HTTPHEADER, array(    'Content-Type: application/json',    'Content-Length: ' . strlen($payload))); // Submit the POST request$result = curl_exec($ch); // Close cURL session handlecurl_close($ch);
