【问题描述】：

我已经实施了新的贝宝快速结账。我想将我的 success_ipn.php URL 和 cancelled.php URL 传递给 checkout.js。

我做了很多谷歌和官方文档Paypal DOC。

下面是我的文件代码：

<!DOCTYPE html>

<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <script src="https://www.paypalobjects.com/api/checkout.js"></script>
</head>

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

    <script>
        var EXECUTE_PAYMENT_URL = 'http://example.com/success_ipn.php';
        paypal.Button.render({

            env: 'sandbox', // sandbox | production

            // PayPal Client IDs - replace with your own
            // Create a PayPal app: https://developer.paypal.com/developer/applications/create
            client: {
                sandbox:    'My Sandbox Client ID here.',
                //production: '<insert production client id>'
            },

            // Show the buyer a 'Pay Now' button in the checkout flow
            commit: true,

            // payment() is called when the button is clicked
            payment: function(data, actions) {

                // Make a call to the REST api to create the payment
                return actions.payment.create({
                    payment: {
                        transactions: [
                            {
                                amount: { total: '0.01', currency: 'USD' }
                            }
                        ]
                    }
                });
            },

            // onAuthorize() is called when the buyer approves the payment
            onAuthorize: function(data, actions) {
                return paypal.request.post(EXECUTE_PAYMENT_URL, {
                    paymentID: data.paymentID,
                    payerID:   data.payerID
                }).then(function() {
                        window.alert('Payment Complete!');
                });
            }

        }, '#paypal-button-container');

    </script>
</body>
</html>

它工作正常，但是我如何传递我的 IPN 文件 URL 和取消 URL。

在对此做更多的谷歌之后，我只能得到以下变量而不是交易 ID 等：

paymentID: data.paymentID,
payerID:   data.payerID

请帮帮我。

【解决方案1】：

在尝试过并对此进行谷歌搜索后，我找到了解决方案。

checckout.js 最新版本之后，贝宝已弃用 Express Checkout - NVP/SOAP。因此，GetExpressCheckoutDetails 和 DoExpressCheckoutPayment 也已被弃用。

现在，所有工作都将在 Rest API 上完成。

以下是更新代码，我们如何以 json 格式获取付款人信息和交易详细信息。得到 json 响应后，我们也可以使用 aJax 更新我们的数据库记录。

<script src="https://www.paypalobjects.com/api/checkout.js"></script>
  <div id="paypal-button-container"></div>

<script>
  var EXECUTE_PAYMENT_URL = 'http://example.com/success_checkout.php';

  paypal.Button.render({

      env: 'sandbox', // sandbox | production

      // PayPal Client IDs - replace with your own
      // Create a PayPal app: https://developer.paypal.com/developer/applications/create
      client: {
          sandbox:    '',
          //production: '<insert production client id>'
      },

      // Show the buyer a 'Pay Now' button in the checkout flow
      commit: true,

      // payment() is called when the button is clicked
      payment: function(data, actions) {

          // Make a call to the REST api to create the payment
          return actions.payment.create({
              payment: {
                  transactions: [
                      {
                          amount: { total: '10', currency: 'USD' },
                          custom: 'custom value here'
                      }
                  ]
              }
          });
      },
      onAuthorize: function(data, actions) {
        return actions.payment.get().then(function(payment) {
            //debugger;
            console.log(payment);
            var txn_id = payment.cart;
            var bookID = payment.transactions[0].custom;
            var currency = payment.transactions[0].amount["currency"];
            var amount = payment.transactions[0].amount["total"];
            var payerID = payment.payer.payer_info["payer_id"];
            var pstatus = payment.payer.status;

            var successUrl = EXECUTE_PAYMENT_URL+'?txn_id='+txn_id+'&bookID='+bookID+'&currency='+currency+'&amount='+amount+'&payerID='+payerID+'&pstatus='+pstatus;
            //console.log(newUrl);
           window.location.replace(successUrl);
        });
      },
      onCancel: function(data, actions) {
        var cancelUrl = "http://example.com/cancelled.php";
        //console.log(newUrl);
        window.location.replace(cancelUrl);
      }    

  }, '#paypal-button-container');

</script>

您将在 success_checkout.php 中得到响应，如下所示：

<?php
echo '<pre>' print_r($_REQUEST); 

// do your stuff here

header('Location: thanks.php');
?>

希望这对其他开发者有所帮助。
