payU 支付网关 android 集成中缺少哈希参数

Question

我需要在我的 android 应用程序中集成 payU 支付网关。但是当应用程序试图获取哈希键时，它给我错误提示

缺少哈希参数

在演示应用程序中，有两个生成哈希的选项

if(null == salt) 
        generateHashFromServer(mPaymentParams);
    else 
        generateHashFromSDK(mPaymentParams, intent.getStringExtra(PayuConstants.SALT));

在演示应用程序中有注释说应该完成散列密钥生成在服务器端

所以我将盐作为空值传递

但现在的问题是我必须使用哪个服务器 url 来生成哈希？演示应用程序正在使用这个 url https://payu.herokuapp.com/get_hash

Answer 1

PayU money 不提供任何类型的 API，因此，人们使用 webview 代替。

Answer 2

我几乎没有搜索就找到了解决方案。

只需使用自己的服务器生成所有必需的哈希值。获得所有必需的哈希值后，我们需要使用此哈希值制作 PayuHashes Obj 并像这样传递这个 Obj

Intent intent= new Intent(this, PayUBaseActivity.class);
intent.putExtra(PayuConstants.PAYU_CONFIG, payuConfig);
intent.putExtra(PayuConstants.PAYMENT_PARAMS, mPaymentParams);
intent.putExtra(PayuConstants.PAYU_HASHES, payuHashes);
intent.putExtra(PayuConstants.SALT, salt);

PayU SDK 将负责其余工作

Answer 3

您必须使用自己的服务器 URL 来生成散列键。在 android 应用程序中，您必须设置 3 个强制哈希键，否则您将收到错误 "mandatory hash key is missing".

确保您已将这 3 个键设置为 payuHashes 对象。

payuHashes.setPaymentHash(response.getString("payment_hash"));
payuHashes.setVasForMobileSdkHash(response.getString("vas_for_mobile_sdk_hash"));
payuHashes.setPaymentRelatedDetailsForMobileSdkHash(response.getString("payment_related_details_for_mobile_sdk_hash"));

以下三个哈希是支付流程所必需的，需要在商家服务器上生成： 1.支付哈希是必须从商户服务器端生成的哈希之一。以下是生成 payment_hash 的公式 - sha512(key|txnid|数量|产品信息|名字|电子邮件|udf1|udf2|udf3|udf4|udf5||||||SALT)

vas_for_mobile_sdk_hash 是需要从商家服务器端生成的强制性哈希之一。下面是生成 vas_for_mobile_sdk_hash -

sha512(键|命令|var1|盐)
在这里，var1 将是 "default"

payment_related_details_for_mobile_sdk_hash 是需要从商家服务器端生成的强制性哈希之一。下面是生成 payment_related_details_for_mobile_sdk_hash -

sha512(键|命令|var1|盐) 在这里，var1 将是用户凭据。如果您不使用 user_credentials 然后使用 "default".

从这里参考示例 sdk： https://github.com/payu-intrepos/Android-SDK-Sample-App/releases/

对于服务器端代码，请参考： https://github.com/payu-intrepos/Documentations/wiki/4.-Server-Side

我希望它对其他人有用我在下面找到了一个 php 用于生成哈希的脚本 link

复制 php 代码并编辑密钥和盐。
