用户购买收据是否与他保持一致。如果他在另一台设备上获得相同的应用程序 [英] Does a user purchase receipt remain same for him. If he got the same app on another device

问题描述

我正在使用付费的通用Windows平台应用。我使用
获得了购买收据

 await GetAppReceiptAsync（）; 

我不确定每个用户的哪个收据元素是唯一的。因此，如果用户在另一台设备上获得相同的应用程序，则他不得购买，并且可以允许继续。我使用收据阅读了有关购买验证的文档。这是
示例应用收据。

我们非常感谢任何帮助。

解决方案

嗨Dektk，

收据仅用于验证相应的交易购买。 xml 文件不包含用于标识用户的元素。但它与后端服务器数据库中的用户帐户信息相关联。

我们会根据许可证类型元素检测用户的应用程序许可证。如果它已满，则表示该帐户还可以在其他设备上使用您应用的完整版本。

谢谢。

祝你好运，

I am working on a paid Universal Windows Platform app. I got the purchase receipt using

await GetAppReceiptAsync(); 

I am not sure which of the receipt element is unique per user. so that if the user got the same app on another device he must not purchase and may be allowed to proceed. I read the documentation it was about purchase verification using receipt .here's the example app receipt.

<Receipt Version="1.0" ReceiptDate="2012-08-30T23:10:05Z" CertificateId="b809e47cd0110a4db043b3f73e83acd917fe1336" ReceiptDeviceId="4e362949-acc3-fe3a-e71b-89893eb4f528">

    <ProductReceipt Id="6bbf4366-6fb2-8be8-7947-92fd5f683530" ProductId="Product1" PurchaseDate="2012-08-30T23:08:52Z" ExpirationDate="2012-09-02T23:08:49Z" ProductType="Durable" AppId="55428GreenlakeApps.CurrentAppSimulatorEventTest_z7q3q7z11crfr" />

Hi Dektk,

Receipts are just used to verify the corresponding transaction purchases. The xml file does not contain an element for identifying users. But it's connected with user's account info in backend server database.

And we detect user's license to your app depending on License Type element. If it's full, it means that account could also use the full version of your app on another device.

Thank you.

Best regards,
