如何解決具有基本授權的 PHP cURL 中的「身份驗證參數遺失或無效」錯誤？

<?php
$username = 'ABC';
$password = 'XYZ';
$url = '<URL>';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 30); // Set a timeout of 30 seconds
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
$result = curl_exec($ch);
$status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); // Capture the HTTP status code
curl_close($ch);

echo $result; // Output the response from the API
?>
