我正在尝试将 PayUBiz 集成到我的 Android 应用程序中。它在测试环境中运行良好。

我正在使用的是如下所示。

  1. 测试商家密钥/盐：gtKFFx / eCwWELxi
  2. 我们用于生成哈希的服务器 URL：http://xx.xxx.xx.xx/payment/getPaymentData
  3. 成功 URL - 失败 URL：https ://payu.herokuapp.com/success - https://payu.herokuapp.com/failure
  4. 我在我们的服务器 URL 中传递orderId和userId以生成哈希。

我可以进入可以输入测试卡详细信息的屏幕。但是在输入卡详细信息后，我收到“错误原因：由于哈希参数计算错误导致交易失败”

整个错误屏幕截图如下。

在此处输入图像描述 在此处输入图像描述

我在代码中所做的如下所示。

ActivityConfirmOrder.java

private String merchantKey = "gtKFFx";
private String merchantSalt = "eCwWELxi";
private String userCredentials = merchantKey + ":" + "maulik@techniche.co";

private PayuConfig payuConfig;
private PaymentParams mPaymentParams;

在 onCreate 我放

// PayUBiz initialisation
Payu.setInstance(this);

以下方法不在 onCreate 方法中。

private void makePayment() {

    int environment = PayuConstants.STAGING_ENV;
    sharedPref = new UserSharedPref(this);

    mPaymentParams = new PaymentParams();

    mPaymentParams.setKey(merchantKey);
    mPaymentParams.setAmount(String.valueOf(totalPrice));
    mPaymentParams.setProductInfo("product_info");
    mPaymentParams.setFirstName("Maulik");
    mPaymentParams.setEmail("maulik@techniche.co");
    mPaymentParams.setTxnId(OrderNumber);

    mPaymentParams.setFurl("https://payu.herokuapp.com/failure");

我找到了解决方案，但我还没有申请。

我通过电子邮件发送给 PayUBiz 的客户支持，他们的回复很好。 电子邮件 ID：tech@payu.in / mobile-integration@payu.in

正如我在问题中提到的，我使用TEST ENVIRONMENT和TEST CREDENTIALS以及OUR SERVER URL来生成哈希，这是我错的地方。如果您使用TEST CREDENTIALS和您的服务器 URL进行哈希，它将不起作用。

在TEST ENVIRONMENT中使用所有TESTING RELATED内容，对于LIVE ENVIRONMENT使用所有LIVE RELATED内容。

我用 PayUBiz 的测试 URL https://payu.herokuapp.com/get_hash替换了我们的服务器 URL，它正在工作。
