如何在paypal移动SDK中获取交易id或其他信息

Question

我最近使用以下教程实现了paypal移动支付教程：http://androiddevelopmentanddiscussion.blogspot.com/2014/05/paypal-integration-in-android.html

作为回应，我得到以下信息：

{
    "response": {
        "state": "approved",
        "id": "PAY-1GM934738N157023RKR7OWYI",
        "create_time": "2014-12-03T10:52:17Z",
        "intent": "sale"
    },
    "client": {
        "platform": "Android",
        "paypal_sdk_version": "2.1.0",
        "product_name": "PayPal-Android-SDK",
        "environment": "sandbox"
    },
    "response_type": "payment"
}




{
    "short_description": "Painting 1",
    "amount": "8",
    "intent": "sale",
    "currency_code": "USD"
}

任何一个指导我如何获得交易id和其他信息移动sdk？正如我所看到的，从paypal移动sdk id支付是不同的，而实际的交易id。

任何帮助都将不胜感激。

Answer 1

可以使用SDK：https://developer.paypal.com/webapps/developer/docs/api/#look-up-a-payment-resource返回的支付ID检索支付资源。

通常，这将在您的服务器而不是移动设备上完成。GET操作将需要使用client_id和client_secret生成的访问令牌。

更新链接：

• 获取支付资源：get
• REST身份验证和标头：https://developer.paypal.com/docs/api/auth-headers/

您可以先在单独的调用中获取令牌，然后在另一个调用中使用它来获取事务id，或者只需在一个步骤中组合两个步骤，如下所示：

public void getPayPalTransactionId(String payPalPaymentId) {
    String PAYPAL_PAYMENT = "https://api.sandbox.paypal.com/v1/payments/payment/%s";
    String url = String.format(PAYPAL_PAYMENT, payPalPaymentId);
    Call<PayPalPaymentResponse> callPayment = webApiInterface.getPayPalTransactionId(url, Credentials.basic(PAYPAL_CLIENT_ID, PAYPAL_CLIENT_SECRET));
    callPayment.enqueue(new Callback<PayPalPaymentResponse>() {
        @Override
        public void onResponse(@NonNull Call<PayPalPaymentResponse> call, @NonNull Response<PayPalPaymentResponse> response) {
            if (response.isSuccessful() && response.body() != null)
                String payPalOrderId = response.body().getTransactions().get(0).getRelatedResources().get(0).getSale().getId();
        }

        @Override
        public void onFailure(@NonNull Call<PayPalPaymentResponse> call, @NonNull Throwable t) {
        }
    });
}

在WebApiInterface中

@GET
Call<PayPalPaymentResponse> getPayPalTransactionId(@Url String url, @Header("Authorization") String authorization);

转到下面代码中的onApprove函数，然后转到它所表示的事务ID：

<!-- Include the PayPal JavaScript SDK -->
<script src="https://www.paypal.com/sdk/js?client-id=CLIENT ID IS CORRECTLY ADDED&currency=USD"></script>

<script>
  paypal.Buttons({

    // Sets up the transaction when a payment button is clicked
    createOrder: function(data, actions) {
      return actions.order.create({
        purchase_units: [{
          
          amount: {
            value: '1'
          },
            
        }],
        application_context: {
            shipping_preference: "NO_SHIPPING",
        }
         
      });
    },

    // Finalize the transaction after payer approval
    onApprove: function(data, actions) {
      return actions.order.capture().then(function(orderData) {
        // Successful capture! For dev/demo purposes:
        //    console.log('Capture result', orderData, JSON.stringify(orderData, null, 2));

        // the transaction id is below this comment in the alert
        var transaction = orderData.purchase_units[0].payments.captures[0];
        alert('Transaction '+ transaction.status + ': ' + transaction.id + '\n\nSee console for all available details');

        // When ready to go live, remove the alert and show a success message within this page. For example:
        // var element = document.getElementById('paypal-button-container');
        // element.innerHTML = '';
        // element.innerHTML = '<h3>Thank you for your payment!</h3>';
        actions.redirect('https://wwwwebsite.com/att_thanks.php?id=1640035591');
      });
    }
  }).render('#paypal-button-container');

</script>
