内容类型application / json不返回POST字段

Question

I'm making cURL request to file on my server And it's printing empty array, unless I delete Content-Type: application/json header from request. Why it occure? It should expect json format in return....

$o = [ 'key' => 'value123' ];

        $headers[]  = 'Content-Type: application/json';
        $headers[]  = 'Moj-pierwszy-header: prosty/do/zapamietania';


        $ch = curl_init(); 
        curl_setopt($ch, CURLOPT_URL, $path.'test.php');
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $o);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $output = curl_exec($ch); 
        curl_close($ch);      



        echo( $output );

and the test.php

echo json_encode( $_POST );

Anybody? Any ideas?

Please refer the below code snippet:

     $o = json_encode([ 'key' => 'value123' ]);

     $headers[]  = 'Content-Type: application/json';
     $headers[]  = 'Moj-pierwszy-header: prosty/do/zapamietania';


    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $path.'test.php');
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $o);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($ch); 
    curl_close($ch); 

    echo( $output );

and for output, instead of $_POST use below code snippet:

$post = json_decode(file_get_contents('php://input'));

Hope, it'll work for you.
