应用程序内购买错误

Question

我在App Store上有一个应用程序，它有一个应用程序内购买功能。 应用内购买工作了几个月没有问题，但突然它停止收据验证工作。 我不知道为什么，因为代码没有改变。

有没有人可以为此遮光？ 苹果最近是否改变了一些关于应用程序内购买的内容？

非常感谢！ Eduardo Rangel

如果您正在使用CargoBay的第三方库验证收据，该框架已经有一段时间一直在遭受证书过期，并且不再全面工作，但是有一项工作可以使其部分工作，但是我不确定这是你的情况。

如果您正在使用CargoBay，请在CBPurchaseInfoFromTransactionReceipt中进行以下更改并注释掉将禁用本地安全检查一部分的代码部分。

NSDictionary * CBPurchaseInfoFromTransactionReceipt(NSData *transactionReceiptData, NSError * __autoreleasing *error) { 
NSDictionary *transactionReceiptDictionary = [NSPropertyListSerialization propertyListWithData:transactionReceiptData options:NSPropertyListImmutable format:nil error:error]; 
if (!transactionReceiptDictionary || ![transactionReceiptDictionary respondsToSelector:@selector(objectForKey:)]) { 
    return nil; 
} 

NSString *purchaseInfo = [transactionReceiptDictionary objectForKey:@"purchase-info"]; 
NSDictionary *purchaseInfoDictionary = [NSPropertyListSerialization propertyListWithData:CBDataFromBase64EncodedString(purchaseInfo) options:NSPropertyListImmutable format:nil error:error]; 
if (!purchaseInfoDictionary) { 
    return nil; 
} 

// Comment this section skipping local purchase validation. It's failing in Sandbox due to the old hardcoded certificate from April 2016, and it will move to Production in mid May 2016. 
// Cargobay will still verify the purchase with the Apple Sandbox/Production server after skipping the local verification. Hopefully update hardcoded certificate 
// in order to move back to Cargobay repository. 

/* 
NSString *signature = [transactionReceiptDictionary objectForKey:@"signature"]; 
NSDate *purchaseDate = CBDateFromDateString([purchaseInfoDictionary objectForKey:@"purchase-date"]); 

if (!CBCheckReceiptSecurity(purchaseInfo, signature, purchaseDate)) { 
    if (error) { 
     NSMutableDictionary *userInfo = [NSMutableDictionary dictionary]; 
     [userInfo setValue:NSLocalizedStringFromTable(@"Cannot extract purchase info from transaction receipt because purchase info failed to validate against its signature.", @"CargoBay", nil) forKey:NSLocalizedDescriptionKey]; 
     [userInfo setValue:NSLocalizedStringFromTable(@"Purchase info failed to validate against its signature.", @"CargoBay", nil) forKey:NSLocalizedFailureReasonErrorKey]; 
     *error = [NSError errorWithDomain:CargoBayErrorDomain code:CargoBayErrorCannotExtractPurchaseInfoFromTransactionReceipt userInfo:userInfo]; 
    } 

    return nil; 
} 
*/ 

return purchaseInfoDictionary; 

}
