Node.js Paypal sdk：visa 卡无法使用

Question

我正尝试在 node.js
中使用 PayPal 处理信用卡使用万事达卡，以下代码使用状态代码为 201 的沙箱帐户。
但是，不使用 'visa'、'amex'.
使用 'visa'、'amex' 卡，我得到 500 状态代码，但找不到错误详细信息。谁见过这个案例？

var paypal = require('paypal-rest-sdk');

paypal.configure({
    'mode': 'sandbox',
    'client_id': 'CLIENT_ID',
    'client_secret': 'CLIENT_SECRET_KEY'
});

var payment = {
    "intent": "authorize",
    "payer": {
        "payment_method": "credit_card",
        "funding_instruments": [{
            "credit_card": {
                "type": "visa",//visa//mastercard//amex
                "expire_month": 1,
                "expire_year": 2022,
                "cvv2": "VISA_CCV2",
                "number": "VISA_NUMBER"
            }
        }]
    },
    "redirect_urls": {
        "return_url": "http://127.0.0.1:3000/success",
        "cancel_url": "http://127.0.0.1:3000/err"
    },
    "transactions": [{
        "item_list": {
            "items": [{
                "name": "media dvd",
                "sku": "001",
                "price": "1.00",
                "currency": "USD",
                "quantity": 1
            }]
        },
        "amount": {
            "total": 1.00,
            "currency": "USD"
        },
        "description": " a book on mean stack "
    }]
}

paypal.payment.create(payment, { timeout: 10000 }, function (err, payment) {
    if (err) {
        console.log(err, payment);


    }
    else {
        console.log(payment);
    }
});

Important: The use of the PayPal REST /payments APIs to accept credit card payments is restricted. Instead, you can accept credit card payments with Braintree Direct.

（Braintree direct 将是一个完整的网关帐户，需要帐户批准并且仅适用于企业 in certain countries.）

由于您试图将旧的东西与旧的 SDK 集成，并且不能在实时环境中使用 - 这是最好的 PayPal 替代方案：

使用新的、受支持的 v2 Checkout-NodeJS-SDK
使用带有黑色 Debit/Credit 卡按钮的 PayPal Checkout 前端：https://developer.paypal.com/demo/checkout/#/pattern/server

Answer 2

直接支付仅限信用卡到paypal。因此，您可以使用 Braintree Direct.

实现支付集成

const braintree = require("braintree");

const gateway = new braintree.BraintreeGateway({
   environment: braintree.Environment.Sandbox, // Sandbox or Production
   merchantId: "Your_merchatn_id",
   publicKey: "Your_public key",
   privateKey: "Your_private_key"
});

您可以使用 merchantId, publicKey, privateKey.

进行身份验证

gateway.transaction.sale({
        amount: `10`,
        paymentMethodNonce: "fake-valid-nonce",
        options: {
          submitForSettlement: true,
          storeInVaultOnSuccess: true
        }
      }, function (err, result) {
        if (err) {
          console.error(err);
        }
      
        if (result.success) {
          console.log('Transaction ID: ' + result.transaction.id);
          console.log('Customer ID: ' + result.transaction.customer.id);
            var customer_id = result.transaction.customer.id;
            let creditCardParams = {
                customer_id,
                number: `4111111111111111`,
                expirationDate: `04/2022`,
                cvv: `133`
              };
              
              gateway.creditCard.create(creditCardParams, (err, response) => {
                  if(err) {
                      console.log(err.message);
                  } else {
                      console.log(response);
                  }
              });
         } else {
             console.error(result);
         }
     });
