我正在尝试将PayUBiz集成到我的Android应用程序中。它在测试环境中工作正常。PayUBiz - Android：因错误计算散列参数导致交易失败
我使用的是如下所示。
- 测试商家密钥/盐：gtKFFx/eCwWELxi
- 我们产生hash服务器网址：http://xx.xxx.xx.xx/payment/getPaymentData
- 成功URL - 失败网址：https://payu.herokuapp.com/success - https://payu.herokuapp.com/failure
- 我'正在通过orderId和userId在我们的服务器URL中生成哈希。
我可以去我可以输入测试卡细节的屏幕。但输入卡详细信息后，我得到“错误原因：由于错误计算散列参数导致交易失败”
整个错误屏幕截图如下。
我在做的代码是什么样的下方。
ActivityConfirmOrder.java
private String merchantKey = "gtKFFx";
private String merchantSalt = "eCwWELxi";
private String userCredentials = merchantKey + ":" + "[email protected]";
private PayuConfig payuConfig;
private PaymentParams mPaymentParams;
在我的onCreate把
// PayUBiz initialisation
Payu.setInstance(this);
下面的方法不是在onCreate方法。
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("[email protected]");
mPaymentParams.setTxnId(OrderNumber);
