Why can't get latest_receipt_info

[vincentwyshan]

Following the Official Document: https://developer.apple.com/library/content/releasenotes/General/ValidateAppStoreReceipt/Chapters/ReceiptFields.html#//apple_ref/doc/uid/TP40010573-CH106-SW1

There should be a latest_receipt_info data in response, but we can't directly get this attribute from the response

[youknowone]

There is latest_receipt attribute in the response. (response.latest_receipt) You also can access to the original value using response._latest_receipt_info

@youknowone

latest_receipt and latest_receipt_info are two different things. latest_receipt is the base64 encoded raw receipt data. latest_receipt_info is a JSON array of transactions (the interesting stuff).

Also, the in_app array and the resulting last_in_app field seem to be useless, since it currently only contains the first (original) transaction.

For the most recent transaction (e.g. for auto renewal validation), you need to get the last item of the latest_receipt_info array.

Another thing: when accessing the original value via response._latest_receipt_info, as you suggested, the following warning is emitted:

Given key `latest_receipt_info` is not in __WHITELIST__. It maybe a wrong key.
Check raw data `_` for real receipt data.

I'm sorry, you are right. I want to suggest a proper encapsulation of the data and remove the warning. But becasue I haven't develop any IAP related code for recent days, I have no idea how to treat the field.

Would you mind to help me by one of the following ways?

1. Please show me a sample receipt which has latest_receipt_info field. Fully masked data is ok. I need only keys to run tests. (This will be the best way because I need to add test code for future regression)
2. Please check my fix about the problem is correct: https://github.com/youknowone/itunes-iap/pull/42

@youknowone Thanks! I'm not sure if #42 does fix the issue. I think you changed the behaviour of Response.latest_receipt. I would suggest to add latest_receipt_info as an additional property.

Also, the old Response.latest_receipt did not return a proper value in first place, I think. As I wrote it's a base64 encoded string, but you wrap it in a Receipt object.

The latest_receipt_info would be an array of InApp objects, just like the in_apparray.

Here is a stripped down response from the itunes API:

{
  "status": 0,
  "environment": "Sandbox",
  "receipt": {
    "in_app": [
      ...
    ]
  },
  "latest_receipt_info": [
    ...
  ],
  "latest_receipt": "..."
}

I'll also send you a complete json response via email.

[youknowone]

Thanks, I received your email. I will make a test based on it.

@jox I recreated PR42 and you can check the user interface in test file.

A new version is released with fix. Thank you all!
