我正试图从paypal获得用户输入的详细信息。
Q 1)如何从paypal获得电子邮件地址和其他详细信息?
Q 2)系统生成的邮件应该从success case还是从ipn case发送?
Q 3)交易成功后，我在paypal屏幕上收到消息- '我们将发送确认电子邮件到foo@email.com'，但我根本没有收到任何电子邮件。
注意:我正在沙箱上测试。
Q 4)我不运送任何物品到买方的地址。所以有可能从paypal屏幕上删除送货地址吗?

如果没有更多关于PayPal集成的信息，我无法完全回答，但是:
Q1: PayPal在大多数相关API调用(DoExpressCheckout等)的响应中提供了关于ipn的买方信息。在某些情况下，即使在付款完成之前，它也有单独的专用调用来获取买方信息(例如GetExpressCheckout)。在不知道你正在集成哪个支付产品/api的情况下，不能说更多。
Q2:无论卖家是否使用ipn，付款成功后都会发送电子邮件。IPN和电子邮件是独立的功能，彼此无关。
Q3:沙箱账户只发送沙箱邮件(防止人们误以为它们是真正的支付邮件)。查看如何在PayPal沙箱中查看您的沙箱邮件。
问题4:是的，这对于许多PayPal产品都是可能的，但具体情况因您集成的产品而异。例如，你可以在POST参数中传递&shipping=0，或者你可能需要设置NoShipping=True…要设置/重定向用户进入PayPal授权流程，请阅读相关文档。
