php post-在響應HTTP Post中獲取null

Question

$ _POST有一些問題，我想獲取服務器發送的數據服務器發送的？AdditionalData.cardHolderName = test＆additionalData.cardBin = 123456

HTTP發布

但是我只得到“ null”的回應

    $cardBin = $_POST['additionalData.cardBin'];
    $lastdigit = $_POST['additionalData.cardSummary'];
    $cardHolderName = $_POST['additionalData.cardHolderName'];

以下是有關服務器發送https://docs.adyen.com/developers/api-manual#notificationfields的信息

Answer 1

將帖子替換為get：

$cardBin = $_GET['additionalData.cardBin'];
$lastdigit = $_GET['additionalData.cardSummary'];
$cardHolderName = $_GET['additionalData.cardHolderName'];
