PayPal Express Checkout 集成响应

Question

我目前很难理解我的 PayPal EC 集成的响应。

GetExpressCheckoutDetails 响应是

[CHECKOUTSTATUS] => PaymentActionNotInitiated

但在 DoExpressCheckout 响应中，

[PAYMENTINFO_0_PAYMENTSTATUS] => Completed

我很困惑，这是否意味着已向买家收费并且付款成功与否？我也无法在 PayPal 论坛和门户网站中找到答案...weeeew

以下是完整的回复详情：

在您致电 DoExpressCheckout 之前不会进行付款。

在第一步（SetExpressCheckout + 重定向到 PayPal）中，买家授权您向他收费。现在由您来决定是否通过调用 DoExpressCheckout 来真正获得他的钱。

如果您在 DoExpressCheckout 之后调用 GetExpressCheckoutDetails，您应该会收到付款完成响应。

编辑： 您可能希望在 DoExpresCheckout 之前调用 GetExpressCheckoutDetails 的一个原因是获取买家选择的地址，以防它可能会更改总数，因此它仍然是一个有效的用例。
