【中文标题】通过 REST API 创建的发票导致 PayPal 后端出错【英文标题】:Invoice created via REST API causes error in PayPal backend 【发布时间】:2018-01-03 00:57:54 【问题描述】:去年我创建了一个示例应用程序,它可以使用 REST API 创建、发送和检查 PayPal 发票。一切都像一个魅力,发票出现在我的沙盒卖家后端,它很有效。
今天我使用完全相同的未修改应用程序来创建发票草稿。回复是好的,我什至可以“发送”发票(除了没有人收到任何电子邮件的事实......),我可以得到它的状态(例如是 DRAFT 或 SENT) - 一切似乎都很好。
只有在卖方沙盒帐户的新型后端而不是草稿列表中,我收到一条错误消息,指出发生了错误,我应该重新加载页面(这当然没有帮助)。当我删除上面创建的草稿时,一切又恢复了正常,我可以看到我去年的旧草稿。我创建了一个新草稿,但我再次收到错误,等等。
在实时页面上也会发生同样的事情,所以这似乎不是沙盒问题。
我将 NuGet 包用于 PayPal REST API 和其中的类。我现在发现我可以查看发送到 PayPal 的 JSON。请求如下所示(匿名买家和卖家的电子邮件 - 所有其他字段均未更改,并且使用去年的相同值):

这里有什么问题?
PS:哦,我应该提一下,我当然可以在网页上成功地手动创建发票?
【问题讨论】:
【参考方案1】:好的,通过返回最小发票,然后工作,我能够挑出日期值作为问题的根源。显然可以通过DateTime.MinValue
,但随后 PayPal 网站无法正确处理。
为未使用的日期传递 null
而不是 DateTime.MinValue
可以解决此问题。需要注意的是,过去传递DateTime.MinValue
是可以的。
结案。
