Klarna检查KCO验证

Question

我试图通过Klarna结帐来验证客户是否在20以上.

它们有一个内置的验证函数，参见这里的https://developers.klarna.com/en/se/kco-v2/checkout/use-cases#validate-checkout-order

checkout.php页面看起来像这个

Accept: application/vnd.klarna.checkout.aggregated-order-v2+json
Authorization: Klarna pwhcueUff0MmwLShJiBE9JHA==
Content-Type: application/vnd.klarna.checkout.aggregated-order-v2+json

{
    "purchase_country": "se",
    "purchase_currency": "sek",
    "locale": "sv-se",
    "cart": {
        "items": [
            {
                "reference": "123456789",
                "name": "Klarna t-shirt",
                "quantity": 2,
                "unit_price": 12300,
                "discount": 1000,
                "tax_rate": 2500
            },
            {
                "type": "shipping_fee",
                "reference": "SHIPPING",
                "name": "Shipping fee",
                "quantity": 1,
                "unit_price": 4900,
                "tax_rate": 2500
            }
        ]
    },
        "merchant": {
        "id": "0",
        "terms_uri": "http://example.com/terms.php",
        "checkout_uri": "https://example.com/checkout.php",
        "confirmation_uri": "https://example.com/thankyou.php?sid=123&klarna_order={checkout.order.uri}",
        "push_uri": "https://example.com/push.php?sid=123&klarna_order={checkout.order.uri}",
        "validation_uri": "https://example.com/klarna_validation.php"
    }
}

当客户裁剪“立即购买”时，klarna_validation.php脚本将运行，并以HTTPSTAT202OK或303 (参见其他方式)向Klarna发送返回。

下面是我的klarna_validation.php

<?php
    $pno = $_POST['customer']['date_of_birth'];
    $birthdate = new DateTime("$pno");
    $today     = new DateTime();
    $interval  = $today->diff($birthdate);
    $interval2 = $interval->format('%y');
    if($interval2 <= "20"){
    header("Location: https://example.com/too_young.php?$pno", true, 303);
    exit;
    } else {
    http_response_code(200);
    }
?>

根据Klarna:的帖子请求将发送给merchant.validation_uri。请求的主体将包含当前的订单信息。订单信息的结构与获取订单的结果相同，正如您在呈现签出时所看到的那样。

问题是，我没有从$_POST'customer';中获得任何数据，它是空的。

为了验证这个$_POST'customer';是空的，我已经将它包含在too_young.php页面的URL中，如下面(too_young.php?$pno)所示。登陆too_young.php时，$pno是空的！( urls看起来像这个too_young.php?)

有人知道我做错了什么吗？

我们终于开始工作了！

我们只需将此代码添加到验证文件中：

$post_data = json_decode(file_get_contents('php://input')，true)；

如下所示：

<?php

$post_data = json_decode(file_get_contents('php://input'), true);

$pno = $post_data['customer']['date_of_birth'];
$birthdate = new DateTime("$pno");
$today     = new DateTime();
$interval  = $today->diff($birthdate);
$interval2 = $interval->format('%y');
if($interval2 < "60"){
header("Location: https://example.com/too_young.php?$pno&$interval2", true, 303);
exit;
} else {
http_response_code(200);
}
?>
