php - Paypal API : The totals of the cart item amounts do not match order amounts

Question

关于这个错误的帖子有很多，但都不适用于我。我真的不明白为什么金额不匹配。我有匹配 AMT0 * QTY0 的 ITEMAMT。而AMT匹配ITEMAMT + SHIPPINGAMT。我一遍又一遍地检查文档，它确实应该以这种方式工作。当我完全移除它的运输时它会起作用......

结帐网址中的 AMT 也是 73.9。

我真的希望有人熟悉这个非常令人困惑的错误，并且知道我做错了什么......

提前致谢

Answer 1

您发送的货币必须保留 2 位小数。您似乎只提供了 1 个。

$amt = 61.9;
$amt = sprintf("%.2f",$amt); // 61.90

Paypal 将返回此错误，因为金额格式不正确:

查看AMT 行下的表A.2:

每次设置“金钱”参数时都应应用此规则。
