PayPal API:购物车项目金额的总计与订单金额不匹配

Question

有很多关于此错误的帖子,但它们都不适用于我.我真的不明白为什么金额不匹配.我有与AMT0*QTY0匹配的ITEMAMT.AMT与ITEMAMT + SHIPPINGAMT相匹配.我一遍又一遍地检查了文档,它确实应该以这种方式工作.当我完全删除它的运输时,它的工作原理...

结帐网址中的AMT也是73.9.

我真的希望有人熟悉这个令人困惑的错误,并且知道我做错了什么......

提前致谢

我的问题的答案可能对大多数路过的人没有帮助。但我的其中一件物品的描述中包含 & (L_PAYMENTREQUEST_0_DESC0)。'&' 转义了通过 CURL 传递的数据。这就产生了错误（完全关闭）。请记住，当您在 URL 编码时输入任何包含 & 的字符时，也会发生这种情况，例如 \xc3\xa9 将变为é

我很抱歉从我的第一篇文章中删除了物品描述，但由于有关金额的错误消息，我不知道这与此有关。
