我在我的项目中使用了这个类：http:
//www.saaraan.com/2012/07/paypal-expresscheckout-with-php
我修改了 process.php 中的一些编码。
并将 2 个 json 变量传递到 php 中以获取交易数据。
交易成功。但最终只能在卖家账户中显示总价。
这很奇怪。
我查看了旧帖子，但没有运气...
- 我已设置使用最新版本的 nvp 106.0
- 我为 webscr url 重定向添加了 useraction=commit。
- 我有 SetExpressCheckOut 方法和 DoExpressCheckOut 方法的设置项目参数。
我的情况有什么解决方案吗？？~
这是我的编码：
