推荐答案
默认情况下为 Express Checkout 启用订单项支持 afaik.因此，当您说启用它时，您可能启用的是 Payflow 的订单项详细信息.. 但这不是重点.
Line item support is enabled for Express Checkout by default afaik. So what you probably enabled when you say you enabled it was line item details for Payflow.. but that's besides the point.
得到您的答案，您的订单项详细信息以n作为付款索引列出，应该替换为 0, 1, 2, 3, 4, 5, 6, 7、8、9 或 10，具体取决于项目所属的付款方式.(如果您想了解更多信息，请查看 PayPal 的并行支付，但在了解更多基础知识后再进行).所以基本上，为了解决您的问题，您将每个订单项参数的 'n' 替换为 '0'，减去引号.见下文:
Getting to your answer, your line item details are listed with n as the index for the payment, which should be replaced with 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10, depending on which payment the items belong to. (Look into PayPal's parallel payments if you want more information, but do it later once you understand more about the basics). So basically, to fix your issue, you replace the 'n' with '0' for each line item parameter, minus the quotes. See below:

请记住，要获取 EC 的订单项详细信息(这也是在 通过payflow 生成 EC 时)，您必须至少发送名称、数量和金额.使用您的代码，PayPal 无法识别出您发送了其中任何一个，因为n"是无效的付款请求索引.
Remember that to get line item details for EC (this is also when the EC is being generated through payflow) you must send at least the name, quantity, and amount. With your code, PayPal wasn't recognizing that you sent any of them, because 'n' is an invalid payment request index.
