我正在开发一项服务,其中发件人支付一定金额,其中 95% 给一个接收者,5% 给另一个。(例如,支付 100 美元,初级费用减少 95 美元,二级费用减少 5 美元。)在此示例中,发件人将 95 美元视为他要支付的金额,而不是 100 美元,我不明白为什么。

这里的金额设置在一个数组中,对应于另一个 Paypal 电子邮件地址数组。

$receiverAmountArray = array(
        .5*$backing_amount,
        .95*$backing_amount
        );

第二个电子邮件地址设置为主。最大金额的接收者必须是主要的。

$receiverPrimaryArray = array(
        'false',
        'true'
        );

CallPay(来自 Paypal 的库)被称为:

$resArray = CallPay ($actionType, $cancelUrl, $returnUrl, $currencyCode, $receiverEmailArray,
                        $receiverAmountArray, $receiverPrimaryArray, $receiverInvoiceIdArray,
                        $feesPayer, $ipnNotificationUrl, $memo, $pin, $preapprovalKey,
                        $reverseAllParallelPaymentsOnError, $senderEmail, $trackingId
);

这是CallPay功能。对不起,长度:

function CallPay( $actionType, $cancelUrl, $returnUrl, $currencyCode, $receiverEmailArray, $receiverAmountArray,
                        $receiverPrimaryArray, $receiverInvoiceIdArray, $feesPayer, $ipnNotificationUrl,
                        $memo, $pin, $preapprovalKey, $reverseAllParallelPaymentsOnError, $senderEmail, $trackingId )
    {
        /* Gather the information to make the Pay call.
            The variable nvpstr holds the name value pairs
        */

        // required fields
        $nvpstr = "actionType=" . urlencode($actionType) . "&currencyCode=" . urlencode($currencyCode);
        $nvpstr .= "&returnUrl=" . urlencode($returnUrl) . "&cancelUrl=" . urlencode($cancelUrl);

        if (0 != count($receiverAmountArray))
        {
            reset($receiverAmountArray);
            while (list($key, $value) = each($receiverAmountArray))
            {
                if ("" != $value)
                {
                    $nvpstr .= "&receiverList.receiver(" . $key . ").amount=" . urlencode($value);
                }
            }
        }

        if (0 != count($receiverEmailArray))
        {
            reset($receiverEmailArray);
            while (list($key, $value) = each($receiverEmailArray))
            {
                if ("" != $value)
                {
                    $nvpstr .= "&receiverList.receiver(" . $key . ").email=" . urlencode($value);
                }
            }
        }

        if (0 != count($receiverPrimaryArray))
        {
            reset($receiverPrimaryArray);
            while (list($key, $value) = each($receiverPrimaryArray))
            {
                if ("" != $value)
                {
                    $nvpstr = $nvpstr . "&receiverList.receiver(" . $key . ").primary=" . urlencode($value);
                }
            }
        }

        if (0 != count($receiverInvoiceIdArray))
        {
            reset($receiverInvoiceIdArray);
            while (list($key, $value) = each($receiverInvoiceIdArray))
            {
                if ("" != $value)
                {
                    $nvpstr = $nvpstr . "&receiverList.receiver(" . $key . ").invoiceId=" . urlencode($value);
                }
            }
        }

        // optional fields
        if ("" != $feesPayer)
        {
            $nvpstr .= "&feesPayer=" . urlencode($feesPayer);
        }

        if ("" != $ipnNotificationUrl)
        {
            $nvpstr .= "&ipnNotificationUrl=" . urlencode($ipnNotificationUrl);
        }

        if ("" != $memo)
        {
            $nvpstr .= "&memo=" . urlencode($memo);
        }

        if ("" != $pin)
        {
            $nvpstr .= "&pin=" . urlencode($pin);
        }

        if ("" != $preapprovalKey)
        {
            $nvpstr .= "&preapprovalKey=" . urlencode($preapprovalKey);
        }

        if ("" != $reverseAllParallelPaymentsOnError)
        {
            $nvpstr .= "&reverseAllParallelPaymentsOnError=" . urlencode($reverseAllParallelPaymentsOnError);
        }

        if ("" != $senderEmail)
        {
            $nvpstr .= "&senderEmail=" . urlencode($senderEmail);
        }

        if ("" != $trackingId)
        {
            $nvpstr .= "&trackingId=" . urlencode($trackingId);
        }

        /* Make the Pay call to PayPal */
        $resArray = hash_call("Pay", $nvpstr);

        /* Return the response array */
        return $resArray;
    }

这是调用前 $nvpstr 的值。Paypal 是否可能只是将付款金额作为主要付款?这在链式支付的背景下没有意义。

根据Paypal 的自适应支付文档

在链式支付中,发送者向主要接收者支付一定金额,主要接收者从中支付次要接收者。发送者只知道主要接收者,不知道次要接收者。

因此,这是按预期工作的。为了向二级收款人支付总金额的 5%,我必须更改以下内容:

$receiverAmountArray = array(
        .05*$backing_amount,
        .95*$backing_amount
        );

对此:

$receiverAmountArray = array(
        .05*$backing_amount,
        $backing_amount
        );

认为总金额是数组中各个接收者金额的总和是我的错误。

例如:total_amount = 100;

如果我们设置receiverList.receiver(0).primary=true 那么receiverList.receiver(0).amount = total_amount;

和receiverList.receiver(1).amount=95%*total_amount
