Question

我正在使用https://github.com/paypal/PayPal-node-SDK。对于网络支付（浏览器），它可以工作。但对于移动设备（iOS / Andriod）却没有，尝试执行付款会产生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差异是：

对于web paypal，返回paymentId和payerId，我可以在执行时使用。对于移动设备，我只收到paymentId，因此我将通过致电Paypal查询payerId。

（我收到付款人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，我注意到付款状态是“已创建”。对于移动它的“批准”。与网络相比，看起来移动设备处于更正确的状态？但失败了。这是为什么？

Answer 1

对于Mobile SDK，它处理移动应用程序中付款的重定向和执行。因此，您将收到HATEOAS链接以获取付款信息和退款信息。该交易已在此时完成。

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

TL; DR：Mobile SDK已经执行了付款。

PayPal执行付款会返回PAYMENT_STATE_INVALID
