我正在尝试使用 Parallel Paypal Express Checkout 下订单。这是 API实现。
我正在使用PAYMENTREQUEST_0_PAYMENTACTION => OrderinSetExpressCheckout和 inDoExpressChecoutPayment并给出错误（这是必需的）。
当我使用 PAYMENTREQUEST_0_PAYMENTACTION => OrderinSetExpressCheckout和PAYMENTREQUEST_0_PAYMENTACTION => Salein时，DoExpressChecoutPayment它可以工作。
一切顺利，直到DoExpressChecoutPayment。请检查这个
