    "Authorization: Basic gfdsds"
  ),
));

$response = curl_exec($curl);

curl_close($curl);
echo $response;````

CodePudding user response：

The value of CURLOPT_POSTFIELD option must be JSON format!

Like this:

$data = json_encode(array(
    "name"  => "Steve",
    "amount" => 12345,
    "user"  => 123456789
));

$curl = curl_init();

curl_setopt_array($curl, array(
    ...
    CURLOPT_POSTFIELDS => $data,
    ...
));
