Validating auto-renewable subscription receipt and updating Parse using Cloud Code

Question

I am developing an iOS app that uses Parse as the backend and users subscribe using Apple's auto-renewable subscription IAP. During the Subscribe and Restore Purchases functions, I pass the receipt as a parameter in a Cloud Code function and then POST that to Apple's server via Parse, as described in this SO answer.

I would like to parse the HTTPResponse and update the user object in Parse with the expires_date property of the JSON receipt. I think my Cloud Code function must be off a bit, because my console shows Result: TypeError: Cannot read property 'status' of undefined, meaning that HTTPResponse.data is undefined(?). My function is below, followed by the console log.

Also, I'm not 100% clear on whether I should be using receipt, latest_receipt, or latest_receipt_info for accessing the expires_date property, so I have some extra variables in there just to test what comes out.

(Thanks for any help as Cloud Code is the only JavaScript that I've ever written.)

Parse.Cloud.define('validateReceipt', function (request, response) {
var user = request.user;
var receiptAsBase64EncodedString = request.params.receiptData;

var postData = {
    method: 'POST',
    url: 'https://sandbox.itunes.apple.com/verifyReceipt',
    body: { 'receipt-data': receiptAsBase64EncodedString,
            'password': 'SECRET' }
}

Parse.Cloud.httpRequest(postData).then(function (httpResponse) {
    // httpResponse is a Parse.Cloud.HTTPResponse

    var json = httpResponse.data; // Response body as a JavaScript object.
    var validationStatus = json.status; // App Store validation status code. If 0, the receipt is valid, but may be expired
    var receiptJSON = json.receipt; // Receipt data as a JSON object
    var latestReceipt = json.latest_receipt; 
    var latestReceiptInfo = json.latest_receipt_info;

    console.log('JSON: ' + json);

    console.log('Latest Receipt Info: ' + latestReceiptInfo);

    console.log('Validation status: ' + validationStatus);

    var now = new Date().getTime();
    var expirationDate = latestReceiptInfo.expires_date;
    console.log('Now: ' + now)
    console.log('Expiration Date: ' + expirationDate)


    if (expirationDate > now) { //updates expiration date
        user.set("accountExpDate", expirationDate);
        user.set("accountStatus", 1);
        user.save();

        return response.success('Subscription Active, expiration date: ' + expirationDate);

    } else {
        user.set("accountStatus", 2);
        user.save();

        return response.error('Subscription Expired, expiration date: ' + expirationDate);
    }
})

});

Edit

console.log(JSON.stringify(httpResponse, null, 4)); gave me

Answer 1

Try this:

var validationStatus = JSON.parse(httpResponse["text"])["status"];

Solved the problem for me.
