node.js - PayPal 执行付款返回 PAYMENT_STATE_INVALID

Question

我正在使用 https://github.com/paypal/PayPal-node-SDK .对于网络支付(浏览器)，它有效。但对于移动设备 (iOS/Andriod) 则不会，尝试执行付款会得到 PAYMENT_STATE_INVALID

{ [Error: Response Status : 400]
  response: 
   { name: 'PAYMENT_STATE_INVALID',
     message: 'This request is invalid due to the current state of the payment',
     information_link: 'https://developer.paypal.com/webapps/developer/docs/api/#PAYMENT_STATE_INVALID',
     debug_id: '2432d6f51f033',
     httpStatusCode: 400 },
  response_stringified: '{"name":"PAYMENT_STATE_INVALID","message":"This request is invalid due to the current state of the payment","information_link":"https://developer.paypal.com/webapps/developer/docs/api/#PAYMENT_STATE_INVALID","debug_id":"2432d6f51f033","httpStatusCode":400}',
  httpStatusCode: 400 }

我注意到网络和移动设备之间的区别是:

对于 web paypal，返回 paymentId 和 payerId，我可以在执行时使用它们。对于移动设备，我只获取 paymentId，所以我将通过调用 Paypal 来查询 payerId。

(我得到付款人 ID 的付款信息)

{ id: 'PAY-7S571696JF513951VKYCRD5Q',
  create_time: '2015-09-25T09:20:54Z',
  update_time: '2015-09-25T09:21:02Z',
  state: 'approved',
  intent: 'sale',
  payer: 
   { payment_method: 'paypal',
     status: 'VERIFIED',
     payer_info: 
      { email: '...',
        first_name: 'test',
        last_name: 'buyer',
        payer_id: 'HBT36U55GA6R8' } },
  transactions: 
   [ { amount: [Object],
       description: '...',
       related_resources: [Object] } ],
  links: 
   [ { href: 'https://api.sandbox.paypal.com/v1/payments/payment/PAY-7S571696JF513951VKYCRD5Q',
       rel: 'self',
       method: 'GET' } ],
  httpStatusCode: 200 }

在执行付款之前，对于网络，我注意到付款状态为“已创建”。对于移动设备，它是“已批准”的。与网络相比，移动设备似乎处于更正确的状态？但是失败了。这是为什么？

对于移动 SDK，它处理移动应用程序中支付的重定向和执行。因此，您将返回付款信息和退款信息的 HATEOAS 链接。此时交易已经完成。

对于网络，您仍然需要重定向客户然后执行付款，这听起来好像您已经在做并且工作正常。

TL;DR:移动 SDK 已执行付款。
