Question

好的，这就是我的所作所为：

创建了PayRequest
SetPaymentOptions - https://developer.paypal.com/webapps/developer/docs/classic/api/adaptive-payments/SetPaymentOptions_API_Operation/
ExecutePayment - “此付款申请必须由发件人授权”。我已经不知道为什么我无法执行付款。根据我的理解，一旦我成功执行付款，我将获得payKey，我将使用它将用户重定向到paypal。 https://developer.paypal.com/webapps/developer/docs/classic/api/adaptive-payments/ExecutePayment_API_Operation/

附件是我使用的源代码。这些值都是硬编码的。我尽力审视类似的问题，这对我来说毫无意义，因为它与我的理解相矛盾。一些答案指出买方需要在执行付款之前先批准付款。

我只是想在到达paypal登录页面时看到所有项目的详细信息。

$endPoint = "https://svcs.sandbox.paypal.com/AdaptivePayments/Pay";

Answer 1

我希望我能正确理解你。

对我而言，您似乎正在跳过用户需要授权付款的步骤。当您执行Pay（创建）操作时，您应该看到在PayPal的响应中获得RedirectURL。您需要将用户重定向到此URL，以便他们在PayPal上授权付款。

一旦他们批准了付款，您就可以执行付款。

您的步骤需要更改为：

创建PayRequest
设置PaymentOptions
重定向到PayPal（来自PayRequest响应的RedirectURL）以进行用户授权
如果获得授权，则执行付款

PayPal在the Pay API operation page

URL to redirect the sender's browser to after the sender has logged into PayPal and approved a payment; it is always required but only used if a payment requires explicit approval

在第3步之后，用户将返回到您在$data['returnUrl'] = $returnURL;

Answer 2

我正在使用延迟链式付款，我经常会遇到此错误“此付款申请必须由发件人授权”。实际上这是由于逻辑上的一个小错误。

错误的程序（@步骤3）

成功生成payKey
将其保存到数据库

因某种原因刷新页面，导致生成新的payKey（这个新的payKey不会更新到数据库）

payRequest = pay();
.....
if(empty(db_record)) {
  .....
  db_record->payKey = payRequest->payKey;
  db_record->save();
}

使用新的payKey付款（即发件人批准的付款）
尝试使用payKey从数据库执行付款（这确实很旧。那个payKey不习惯付款）

解决方案

用最后一个payKey更新数据库，用于通过获得发件人的批准进行付款

第3步应该是

    if(empty(db_record) || is_expired(db_record->payKey)) {
      payRequest = pay();
      .....
      .....
      db_record->payKey = payRequest->payKey;
      db_record->save();
    }

此付款申请必须由发件人授权 - Paypal
