【问题描述】：
我正在快速测试自动更新的应用内购买，我发现我的代码存在一些奇怪的问题。
我正在沙盒环境中测试这些功能
- 用户可以购买一个月、一年的自动续订或永久许可
- 每次用户打开应用时，应用都要检查订阅是否仍然有效，如果没有，则锁定所有高级功能
- 用户能够恢复购买的计划，应用程序应该得到以前购买的类型，即。一个月、一年或永久。
经过长期研究教程，我仍然对验证感到困惑
- 我看到有两种验证收据的方法，一种是在本地，另一种是在服务器上。 但是我没有服务器，是不是只能在本地验证呢
- 每次自动续费订阅到期时，本地收据都不会更新，所以当我重新打开应用程序时，我收到订阅到期警报（我自己定义的验证检查方法），当我点击恢复按钮时，应用恢复成功，收据已更新
- 经过6次手动恢复并刷新收据（沙盒用户只能更新6次），当我点击恢复按钮时，部分交易== .purchased被调用，我的应用程序解锁了高级功能，但是当我重新打开我的应用，我的应用提醒订阅已过期，这是应该的。
我的核心问题是每次打开应用，我没有服务器，不知道为什么收据没有自动刷新时，如何检查Apple的订阅验证
这是我的代码的一些部分，我在打开应用程序时调用了 checkUserSubsriptionStatus()，我正在使用 TPInAppReceipt 库
class InAppPurchaseManager {
static var shared = InAppPurchaseManager()
init() {
}
public func getUserPurchaseType() -> PurchaseType {
if let receipt = try? InAppReceipt.localReceipt() {
var purchaseType: PurchaseType = .none
if let purchase = receipt.lastAutoRenewableSubscriptionPurchase(ofProductIdentifier: PurchaseType.oneMonth.productID) {
purchaseType = .oneMonth
}
if let purchase = receipt.lastAutoRenewableSubscriptionPurchase(ofProductIdentifier: PurchaseType.oneYear.productID) {
purchaseType = .oneYear
}
if receipt.containsPurchase(ofProductIdentifier: PurchaseType.permanent.productID) {
purchaseType = .permanent
}
return purchaseType
} else {
print("Receipt not found")
return .none
}
}
public func restorePurchase(in viewController: SKPaymentTransactionObserver) {
SKPaymentQueue.default().add(viewController)
if SKPaymentQueue.canMakePayments() {
SKPaymentQueue.default().restoreCompletedTransactions()
} else {
self.userIsNotAbleToPurchase()
}
}
public func checkUserSubsriptionStatus() {
DispatchQueue.main.async {
if let receipt = try? InAppReceipt.localReceipt() {
self.checkUserPermanentSubsriptionStatus(with: receipt)
}
}
}
private func checkUserPermanentSubsriptionStatus(with receipt: InAppReceipt) {
if let receipt = try? InAppReceipt.localReceipt() { //Check permsnent subscription
if receipt.containsPurchase(ofProductIdentifier: PurchaseType.permanent.productID) {
print("User has permament permission")
if !AppEngine.shared.currentUser.isVip {
self.updateAfterAppPurchased(withType: .permanent)
}
} else {
self.checkUserAutoRenewableSubsrption(with: receipt)
}
}
}
private func checkUserAutoRenewableSubsrption(with receipt: InAppReceipt) {
if receipt.hasActiveAutoRenewablePurchases {
print("Subsription still valid")
if !AppEngine.shared.currentUser.isVip {
let purchaseType = InAppPurchaseManager.shared.getUserPurchaseType()
updateAfterAppPurchased(withType: purchaseType)
}
} else {
print("Subsription expired")
if AppEngine.shared.currentUser.isVip {
self.subsrptionCheckFailed()
}
}
}
private func updateAfterAppPurchased(withType purchaseType: PurchaseType) {
AppEngine.shared.currentUser.purchasedType = purchaseType
AppEngine.shared.currentUser.energy += 5
AppEngine.shared.userSetting.hasViewedEnergyUpdate = false
AppEngine.shared.saveUser()
AppEngine.shared.notifyAllUIObservers()
}
public func updateAfterEnergyPurchased() {
AppEngine.shared.currentUser.energy += 3
AppEngine.shared.saveUser()
AppEngine.shared.notifyAllUIObservers()
}
public func purchaseApp(with purchaseType: PurchaseType, in viewController: SKPaymentTransactionObserver) {
SKPaymentQueue.default().add(viewController)
if SKPaymentQueue.canMakePayments() {
let paymentRequest = SKMutablePayment()
paymentRequest.productIdentifier = purchaseType.productID
SKPaymentQueue.default().add(paymentRequest)
} else {
self.userIsNotAbleToPurchase()
}
}
public func purchaseEnergy(in viewController: SKPaymentTransactionObserver) {
SKPaymentQueue.default().add(viewController)
let productID = "com.crazycat.Reborn.threePointOfEnergy"
if SKPaymentQueue.canMakePayments() {
let paymentRequest = SKMutablePayment()
paymentRequest.productIdentifier = productID
SKPaymentQueue.default().add(paymentRequest)
} else {
self.userIsNotAbleToPurchase()
}
}
}
