[iOS] transaction receipt problem

Hi.
Under normal purchasing conditions,
AppleExtensions.GetTransactionReceiptForProduct works well in ProcessPurchase.

After purchasing from ProcessPurchase,
PurchaseProcessingResult.Pending returned for server validation.
We then try to test various situations, such as crashes, by quitting the application.

After the application is restarted, initializing UnityIAP
If an incomplete transaction exists
ProcessPurchase is called again.

However, in this call situation, we can check the app receipt.
but Calling AppleExtensions.GetTransactionReceiptForProduct
does not get the current transaction receipt.

How do I get a transaction receipt for an abnormally terminated transaction?

Thank you.

 

Please provide exact steps to reproduce and the results that you see, including the transaction history.

 

The following code

Code (CSharp):

1.  
2. public PurchaseProcessingResult ProcessPurchase( PurchaseEventArgs purchaseEventArgs )
3. {
4.     Debug.Log( "ReceiptForProduct = " + m_AppleExtensions.GetTransactionReceiptForProduct( purchaseEventArgs.purchasedProduct ) );
5.  
6.     ......
7.  
8.     return PurchaseProcessingResult.Pending;
9. }
10.  

I can get a transaction receipt when I buy
If it is pending, it is re-invoked at initialization after execution again.
Nothing.

 

Sorry what do you mean by "re-invoked". We are returning the receipt returned by Apple, we have no control over this.

 

Sorry for the confusion.

At the time of purchase, after returning PurchaseProcessingResult.Pending from ProcessPurchase,
If my code was terminated without calling controller.ConfirmPendingPurchase,
When I rerun my app again and initialize the IAP, ProcessPurchase is called.

At this time, my code can check the application receipt, but not the transaction receipt through m_AppleExtensions.GetTransactionReceiptForProduct.

Thank you.

 

Why not? Please be specific, with examples.

 

Code (CSharp):

1. public PurchaseProcessingResult ProcessPurchase (PurchaseEventArgs purchaseEventArgs) {
2.  
3.     m_LastTransactionID = purchaseEventArgs.purchasedProduct.transactionID;
4.  
5.     try {
6.         var result = validator.Validate (purchaseEventArgs.purchasedProduct.receipt);
7.  
8.         foreach (IPurchaseReceipt productReceipt in result) {
9.  
10.             DateTime utcToLocal = productReceipt.purchaseDate.ToLocalTime ();
11.  
12.             AppleInAppPurchaseReceipt apple = productReceipt as AppleInAppPurchaseReceipt;
13.  
14.             if (productReceipt.transactionID == m_LastTransactionID) {
15.  
16.                 logBuyTransaction += "productID    - " + productReceipt.productID + "\n";
17.                 logBuyTransaction += "purchaseDate - " + productReceipt.purchaseDate + "\n";
18.                 logBuyTransaction += "transactionID - " + productReceipt.transactionID + "\n";
19.                 logBuyTransaction += "utcToLocal - " + utcToLocal + "\n";
20.  
21.                 if (null != apple) {
22.                     logBuyTransaction += "originalTransactionIdentifier = " + apple.originalTransactionIdentifier + "\n";
23.                     logBuyTransaction += "subscriptionExpirationDate = " + apple.subscriptionExpirationDate + "\n";
24.                     logBuyTransaction += "cancellationDate = " + apple.cancellationDate + "\n";
25.                     logBuyTransaction += "quantity = " + apple.quantity + "\n";
26.                 }
27.                 logBuyTransaction += "ReceiptForProduct = " + m_AppleExtensions.GetTransactionReceiptForProduct (purchaseEventArgs.purchasedProduct);
28.  
29.                  Debug.Log (logBuyTransaction);
30.                  //server validation
31.                  ///....
32.  
33.                  return PurchaseProcessingResult.Pending;
34.  
35.             }
36.  
37.  
38.         }
39.  
40.     } catch (IAPSecurityException ex) {
41.         Debug.Log ("Invalid receipt --- " + ex);
42.         return PurchaseProcessingResult.Complete;
43.     }
44.  
45. }
46.
