PHP-Paypal使用nvp和express_checkout的购物车商品总金额与订单金额不符

这是我使用nvp和express_checkout发送给Paypal的信息,但它给我错误的错误是订单金额不匹配,您能帮我请我丢失或错误计算的那一项吗？

我已经阅读了具有相同问题的帖子,但仍然不知道如何从他们的建议答案中找出我的答案.先感谢您.

解决方法:

我上一次玩此游戏时,我使用的是API版本113(现在已经使用了一年多).

我认为您真的只是错过了每个项目的税额.

PAYMENTREQUEST_0_ITEMAMT字段应等于不含税的每个商品金额(L_PAYMENTREQUEST_0_AMTn)的总和乘以数量.所以你应该有

'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,但可以说是

'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的总和

'PAYMENTREQUEST_0_AMT' => 70.00
