使用Inapp购买时是否可以添加额外的数据 [英] Is there a way to add extra data when purchasing using Inapp purchases

问题描述

这是一个场景，我们的应用程序中有多位老师.用户可以从老师那里购买3种不同的物品，价格分别为$ 20，$ 30，$ 40.因此，我在Google Play控制台中创建了3种产品.用户购买时我怎么知道他从哪个老师那里买的东西?购买该商品时，我看不到任何设置额外数据的方法.人们通常如何处理这些案件?

Here is a scenerio , We have multiple teachers on our app . User can purchase 3 different items from teacher which costs $20, $30, $40 . So I created 3 products in google play console . When user purchases some item how can I know from which teacher he purchased the item from ? I don't see any way to set extra data when purchasing the item . How people generally handles these cases ?

这是我用来启动付款屏幕的方法

This is the method I use to launch payment screen

 fun buyAnItem(activity:Activity,skuDetails: SkuDetails) {
    val flowParams = BillingFlowParams.newBuilder()
        .setSkuDetails(skuDetails)
        .build()
    val responseCode =
        billingClient.launchBillingFlow(activity, flowParams)
    log(responseCode.toString())
}

我看不到在 SkuDetails 或 BillingFlowParams.newBuilder()

我怎么能看到可以为 BillingFlowParams.newBuilder() .setObfuscatedAccountId()和 .setObfuscatedProfileId()设置的这两个参数代码>，我应该使用这些吗?对我来说，这似乎是一种hack.

How ever I saw we can set these 2 parameters we can set for BillingFlowParams.newBuilder() .setObfuscatedAccountId() and .setObfuscatedProfileId() , should I be using these ? It looks like a hack to me .

我想找回购买对象中的额外参数

I want to get back the extra params in Purchase object

 override fun onPurchasesUpdated(
    billingResult: BillingResult?,
    purchases: MutableList<Purchase>?
) {
        for (purchase in purchases) {
           consumePurchase(purchase)
       }
    }
}

推荐答案

似乎正确的方法就像使用 setObfuscatedProfileId 和 setObfuscatedAccountId 一样.为不同的用户设置一些唯一的值.每个属性最多允许使用64个字符.

Seems like using setObfuscatedProfileId and setObfuscatedAccountId is the right way. Set some unique values for different users . maximum of 64 charecters is allowed per each property .

val flowParams = BillingFlowParams.newBuilder()
        .setSkuDetails(skuDetails)
        .setObfuscatedProfileId(profileId)  //Some data you want to send
        .setObfuscatedAccountId(id)  //Some data you want to send
        .build()
    val responseCode =
        billingClient?.launchBillingFlow(activity, flowParams)

检索:-，您可以使用 purchase.accountIdentifiers?.obfuscatedAccountId 和 purchase.accountIdentifiers?.obfuscatedProfileId

override fun onPurchasesUpdated(
    billingResult: BillingResult?,
    purchases: MutableList<Purchase>?
) {

    if (billingResult?.responseCode == BillingClient.BillingResponseCode.OK && purchases != null) {
        for (purchase in purchases) {
            CoroutineScope(Dispatchers.Main).launch {
                log(purchase.accountIdentifiers?.obfuscatedAccountId)
                log(purchase.accountIdentifiers?.obfuscatedProfileId)
                consumePurchase(purchase)
            }
        }
    }
}
