Javascript Node.js SDK for PayPal API-尝试创建和执行付款时资源ID无效

我正在尝试使用Node.js PayPal SDK执行基本的PayPal支付。我正在尝试使用“快速结帐”流程

在我的客户端页面上，我有以下代码：

           <div id="paypal-button"></div>

<script>
    paypal.Button.render({

        env: 'sandbox', // Or 'sandbox',

        commit: true, // Show a 'Pay Now' button

        payment: function() {
            return paypal.request.post("/Checkout/checkout").then(function(data) {
              console.log("I returned!" + data.id);
                return data.id;
            });
        },

            onAuthorize: function(data, actions) {
return paypal.request.post("/Checkout/confirmation", {
    paymentID: data.id,
    payerID: data.payerID}).then(function() {
        window.location("/Checkout/Success");
    });        
}
                   }, '#paypal-button');
    </script>

paypal_config.js文件如下所示：

var paypal = require("paypal-rest-sdk");
require("../../config/paypal_config.js");
module.exports = {

    addCart: function(req, res) {
        var items = [];
        var listingID = req.param("id");
        var cartID;

        if (req.cookies.cart == {} || req.cookies.cart == null) { // cart is not set
            // Create cart in DB and in Session
            Cart.create().exec((err, cart) => {
                res.cookie("cart", cart.cartID);
                cartID = cart.cartID;
            });
        } else { // retrieve existing cart using session cookie
            cartID = req.cookies.cart;
        }
        // Add items to cart and recalculate total
        CartItem.create({ quantity: req.param("quan"), listing: listingID, cart: cartID, unitPrice: req.param("unitPrice") }).exec((err, result) => {
            if (!err) {
                return res.redirect("/checkout/cart");
            } else {
                console.log("Error - " + err);
            }
        });

    },

    // read cart, display total, prepare transaction details for PayPal
    cart: function(req, res) {
        return res.view("checkout/cart");
        /*  var cartItems = req.cookies.cart.items;
          CartService.getCartView(cartItems, function(err, results) {
              if (!err) {
                  return res.view("checkout/cart", { items: results });
              }
          });*/

    },

    checkout: function(req, res) {
        Cart.findOne({ cartID: req.cookies.cart }).populate("cartItems").exec( function(err, cart) {
            if (!err) {
                     console.log(cart);
                cart.updateCart();
                cart.save();
                var jsonTran = cart.returnTransactionJSON();
                paypal.payment.create(jsonTran, function(err, payment)  {
if(err) {
    console.log(JSON.stringify(err));
    } else {

console.log("This is the payment.");
      return res.send(payment);
                           }                
                    });
            }
        });
    },

    cancel: function(req, res) {
        return view("checkout/cancel")
    },


    confirmation: function(req, res) {
        var paymentID = req.query.paymentID;
        var payerID = { payer_id: req.query.PayerID };

        paypal.payment.execute(paymentID, payerID, (err, payment) => {
            if (!err && payment.status == "approved") {
                console.log("Payment completed!");
                return view("checkout/confimation");
            } else {
       console.log(JSON.stringify(err));
            }
        })
    }

};

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

paypal.configure({
    "mode": "sandbox",
    "client_id": "MYCLIENTKEY",
    "client_secret": "MYSECRETKEY"
})

我可以使用我的测试帐户登录；但是，每当我单击“立即付款”按钮时，窗口仅停留在“处理…”屏幕上，我收到以下错误：

我的客户端代码记录了以下内容：

I returned!PAY-14496911M2734903LLFNOF4Q

任何帮助都将不胜感激。 谢谢

谢谢您的帮助。

似乎有一些人也遇到过同样的问题，不确定您是否能在这里找到对您有帮助的内容，或者谢谢，我会看一看。非常欢迎，我希望您能从这些人中找到一些帮助。我还没有将paypal与

node.js一起使用过，所以除了上面的评论之外，我无法提供任何进一步的帮助：(
