Question

这是我使用nvp和express_checkout发送给paypal的内容，但是它给我的错误与订单金额不匹配，你能帮我解决哪一个我错过或计算错误？

我已经阅读了相同问题的帖子，但仍然不知道如何从他们建议的答案中修复我的。提前谢谢。

上次我玩这个时，我使用的是API版本113（现已超过一年了）。

我认为你真的只错过了每件税款。

PAYMENTREQUEST_0_ITEMAMT字段应该等于每个项目的金额（L_PAYMENTREQUEST_0_AMTn）的总和，不包括税额，乘以数量。所以你应该

'L_PAYMENTREQUEST_0_AMT0' => 31.82,
'L_PAYMENTREQUEST_0_AMT1' => 31.82,
'PAYMENTREQUEST_0_ITEMAMT' => 63.64

PAYMENTREQUEST_0_TAXAMT是每个项目的税额（L_PAYMENTREQUEST_0_TAXAMTn）乘以数量的总和。您尚未指定项目税额，但让我们说它类似于

'L_PAYMENTREQUEST_0_TAXAMT0' => 3.18,
'L_PAYMENTREQUEST_0_TAXAMT1' => 3.18,
'PAYMENTREQUEST_0_TAXAMT' => 6.36

最后，PAYMENTREQUEST_0_AMT是PAYMENTREQUEST_0_ITEMAMT和PAYMENTREQUEST_0_TAXAMT加上任何送货的总和

'PAYMENTREQUEST_0_AMT' => 70.00

使用带有express_checkout的nvp，Paypal购物车商品金额的总数与订单金额不匹配
