我需要帮助将来自 Postman 的成功请求转换为使用 PHP 的 CURL 命令(涉及 HTTPS 和 POST)

I'm trying to execute this locally using PHP (XAMPP install). The following is getting a response from the server saying the username/password is incorrect:

function curlPost($url, $headers, $username, $password, $data) {
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_CAINFO, 'certificate.pem');
	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
	curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
	curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
	curl_setopt($ch, CURLOPT_HEADER, true);
	curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
	curl_setopt($ch, CURLOPT_TIMEOUT, 30);
	curl_setopt($ch, CURLOPT_POST, true);
	curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
	print_r(curl_exec($ch));
	// print_r(curl_getinfo($ch));
	// print_r(curl_error($ch));
	curl_close($ch);
}

$data = '{"key":"value", "key":"value"}';
curlPost('https://domain.com/api/data', ['Content-Type: application/xml'], 'api_key', '', $data);

{"success":false,"errors":["Email/Username or password incorrect. Please try again."],"warnings":[],"info":[],"meta":[],"results":[]}

$data 中使用的 JSON 字符串是从成功的 Postman 请求中复制和粘贴的.
