我们正在使用Woocommerce和Woocommerce订阅。出于某种原因，默认情况下，Woocommerce订阅（参考交易）不会传递或包含Paypal的税额。所以我最终修改了类文件并添加到字段＆＃34; TAXAMT＆＃34;在IPN中。
然而，当我这样做时，它现在给我们错误：
[L_ERRORCODE0] => 10413
[L_ERRORCODE1] => 10004
[L_SHORTMESSAGE0] => Transaction refused because of an invalid argument. See additional error messages for details.
[L_SHORTMESSAGE1] => Invalid Data
[L_LONGMESSAGE0] => The totals of the cart item amounts do not match order amounts.
[L_LONGMESSAGE1] => This transaction cannot be processed.
[L_SEVERITYCODE0] => Error
[L_SEVERITYCODE1] => Error
任何人都可以帮我确定一下这里丢失了什么或者出了什么问题？ 以下是发送给paypal的IPN请求（通过woocommerce paypal日志）
这是一个经常性的产品。该产品售价7.70美元，税收为0.77美元，总计8.47美元
