Question

在我的代码中，我正在尝试向Paypal REST API发送所需信息，而Paypal正在向我发送“已批准”状态，但为了完成付款，我需要执行付款。

payment.execute(accesstoken,paymentExecution) ...但我无法从回复中获得payer_id。以下是我的代码以获取更多信息，并感谢您的帮助！

public class PaypalPaymentWithCreditCardServlet {    

   // private static final long serialVersionUID = 734220724945040319L;

   // @Override
    public void init () throws Exception {

        InputStream is = PaypalPaymentWithCreditCardServlet.class.getResourceAsStream("/sdk_config.properties");
        try {
                PayPalResource.initConfig(is);
        } catch (PayPalRESTException e) {
               // goto failure page. can't do anything without configuration file
            e.printStackTrace();
        }
    }



    public boolean doPost (PaymentPojo paymentpojo) throws Exception {

        try {

            String accessToken = GenerateAccessToken.getAccessToken();            
            APIContext apiContext = new APIContext(accessToken);

            final Payment payment = new PaymentBuilder().setBillingAddress(paymentpojo.getBillingAddress())
                                                        .setCreditCard(paymentpojo.getCreditCard())
                                                        .setPaymentDetail(paymentpojo.getDetails())
                                                        .setTransactionAmount(paymentpojo.getAmount())
                                                        .build();

            Payment createdPayment = payment.create(apiContext);            

            System.out.println(Payment.getLastResponse());

            System.out.println(String.format("created payment with id [%s] and status=[%s]", createdPayment.getId(), createdPayment.getState()));

            if(!createdPayment.getState().toLowerCase().equalsIgnoreCase(PaypalState.APPROVED.getStatus())) {

                // payment is not created. throw an exception
                System.out.println("Payment handshake did not go through!!!");

                return false;

            }


            // if it is not created throw exception

          //  payment.execute(accessToken, paymentExecution);



          return true;  

        } catch (PayPalRESTException e) {

        }
        return false;


    }

}

对于信用卡付款，payer_id是您用于识别系统中用户的唯一属性（例如电子邮件地址），您每次都会在payerID中提供付款。

如果您不了解用户的信息，例如访客结账，则无需提供付款人ID。

对于paypal付款，始终需要提供payer_id，并在用户批准付款后附加到redirect_url。完整文档位于https://developer.paypal.com/webapps/developer/docs/integration/web/accept-paypal-payment/

如何在我的java代码中以编程方式获取payer_id？
