PayPal沙箱可以吗；收费；交易费？

我试图测试我的侦听器文件如何处理PayPal交易，但是沙箱没有传递任何关于交易费用的信息。我非常确定LivePayPal站点确实将交易费用传递给了一个侦听器文件

以下是发布到侦听器文件的内容：

您应该看到

mc\u费用

和

payment\u费用

的变量。如果您没有看到这些变量，请提供transaciton id，我可以在我这边查看。此外，您还可以找到列出的IPN/PDT变量列表。

也许沙箱不收费。但到目前为止你都试过什么？向我们展示一条以字符串或数组形式打印的IPN消息。要清楚，我指的是沙箱，而不是live PayPal。我现在主要关心的是我的系统设计。上述事务来自沙箱站点。我刚刚运行了另一个沙盒事务-id:4ME46318GF921513F。
