i've tried to do some curl post to my other services using built in magento curl.

i already did this for the curl request

 $this->curl->post($url, $data);

yeah it's work but my data is change to url encoded style. my question is there any ways for me change the style from url encoded to Json Body request?

thanks in advance

Eventually it's worked using the basic Curl without using the magento curl

i am following this link https://stackoverflow.com/questions/21271140/curl-and-php-how-can-i-pass-a-json-through-curl-by-put-post-get

and it works beautifully

This happens when you make a curl request through magento:

vendor/magento/framework/HTTP/Client/Curl.php

protected function makeRequest($method, $uri, $params = [])
{
 $this->_ch = curl_init();
 $this->curlOption(CURLOPT_URL, $uri);
 if ($method == 'POST') 
 $this->curlOption(CURLOPT_POST, 1);
 $this->curlOption(CURLOPT_POSTFIELDS, http_build_query($params));
 elseif ($method == "GET") 
 $this->curlOption(CURLOPT_HTTPGET, 1);
 else 
 $this->curlOption(CURLOPT_CUSTOMREQUEST, $method);
 
...

http_build_query corrupts the format of the json.
If you patiently read the function makeRequest(), you will be surprised that it is not possible to send json in the body or do PUT / DELETE / PATCH ... etc with params. Instead you can use the old one known

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://.../');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode(['a'=>'1', 'b'=>'2']));

$result = curl_exec($ch);
curl_close($ch);

if ($result === false) 
 return false;
 else 
 return $result;
