php - 交易金额详细信息(小计、税金、运费)必须加起来达到指定的总金额 - PayPal PHP SDK

Question

出于某种原因，当我尝试使用 SDK 授权 PayPal 付款时，我的日志中不断出现以下错误:

ERROR: Got Http response code 400 when accessing https://api.sandbox.paypal.com/v1/payments/payment. {"name":"VALIDATION_ERROR","details":[{"field":"transactions[0].amount","issue":"Transaction amount details (subtotal, tax, shipping) must add up to specified amount total"}],"message":"Invalid request - see details"

我的交易金额似乎加起来没问题，所以我不知道为什么 PayPal 会抛出错误，这是我的交易金额:

'transactions' => [
                0 => PayPal\Api\Transaction#5
                (
                    [PayPal\Common\PayPalModel:_propMap] => [
                        'amount' => PayPal\Api\Amount#6
                        (
                            [PayPal\Common\PayPalModel:_propMap] => [
                                'currency' => 'GBP'
                                'total' => '675.00'
                                'details' => PayPal\Api\Details#7
                                (
                                    [PayPal\Common\PayPalModel:_propMap] => [
                                        'fee' => '75.00'
                                        'subtotal' => '600.00'
                                    ]
                                )
                            ]
                        )
                        'item_list' => PayPal\Api\ItemList#8
                        (
                            [PayPal\Common\PayPalModel:_propMap] => [
                                'items' => [
                                    0 => PayPal\Api\Item#9
                                    (
                                        [PayPal\Common\PayPalModel:_propMap] => [
                                            'name' => 'Day 1: 30-12-2017'
                                            'currency' => 'GBP'
                                            'quantity' => 1
                                            'price' => '300.00'
                                        ]
                                    )
                                    1 => PayPal\Api\Item#10
                                    (
                                        [PayPal\Common\PayPalModel:_propMap] => [
                                            'name' => 'Day 2: 27-01-2018'
                                            'currency' => 'GBP'
                                            'quantity' => 1
                                            'price' => '300.00'
                                        ]
                                    )
                                ]
                            ]
                        )

这可能与 number_format 有关吗？功能？我正在使用该函数来确保所有值都与其小数位一致:$grandTotal = number_format($data['job']['grandTotalAmount'], 2, '.', '');

Answer 1

我遇到了这个问题。在我的例子中，解决方案是正确的总计和小计计算:

subtotal 必须是 Price * Quantity

Total 必须是 Tax + shipping + subtotal

不要只是硬编码这些字段。

希望对你有帮助
