Validating iOS iAP receipt

Nascode · May 2013

Hello all,

Would like to get help on step-by-step method to verify receipt on iOS iAP with Gideros StoreKit Plugin. What would we do if we want to use our server or withour server?

For validating from our own server i found this code https://github.com/chrismaddern/validate-in-app-purchase-iphone-ios-receipts .But what parameter should we send? And what if we dont want to use our own server (less secure)? Could we use UrlLoader?

I saw Apple tutorial on how to do this, would like to know if anyone have lua snippet?

Without testing, just converting php code to lua, it should be something like this:

--class
ValidateReceipt = Core.class(EventDispatcher)
 
function ValidateReceipt:init(receipt, sandboxed)
    sandboxed = sandboxed or true
    local url
    if sandboxed then
        url = "<a href="https://sandbox.itunes.apple.com/verifyReceipt&quot" rel="nofollow">https://sandbox.itunes.apple.com/verifyReceipt&quot</a>;
    else
        url = "<a href="https://buy.itunes.apple.com/verifyReceipt&quot" rel="nofollow">https://buy.itunes.apple.com/verifyReceipt&quot</a>;
    end
    local headers = {
        ["Content-Type"]  = "application/x-www-form-urlencoded"
    }
    local body = "receipt-data="..receipt
    local loader = UrlLoader.new(url, UrlLoader.POST, headers, body)
 
    local function onComplete(event)
         local e = Event.new(Event.COMPLETE)
         e.data = event.data
        self:dispatchEvent(e)
    end
 
    loader:addEventListener(Event.COMPLETE, onComplete)
end
 
--usage
local validate = ValidateReceipt.new("YOUR-RECEIPT-HERE")
validate:addEventListener(Event.COMPLETE, function(e)
    local data = Json.decode(e.data)
    if data.status ~= 0 then
        --invalid
    else
        --valid
    end
end)

Hi @ar2rsawseen

Thanks for you lua snippet. What should i put as parameter on "YOUR-RECEIPT-HERE"?

This is the snippet code from a thread by @atilim

require "storekit"
 
local function onRequestProductsComplete(event)
    if event.errorCode ~= nil then
        print("error", event.errorCode, event.errorDescription)
        return
    end
 
    print("products:")
    for i=1,#event.products do
        print("title", event.products[i].title)
        print("description", event.products[i].description)
        print("price", event.products[i].price)
        print("productIdentifier", event.products[i].productIdentifier)
    end
 
    print("invalidProductIdentifiers:")
    for i=1,#event.invalidProductIdentifiers do
        print(event.invalidProductIdentifiers[i])
    end
end
 
local function onTransaction(event)
    print("payment.productIdentifier", event.payment.productIdentifier)
    print("payment.quantity", event.payment.quantity)
 
    print("transaction.state", event.transaction.state)
 
    if event.transaction.state == StoreKit.FAILED then
        print("error", event.errorCode, event.errorDescription)
    else        
        print("transaction.identifier", event.transaction.identifier)
        print("transaction.date", event.transaction.date)
 
        if event.transaction.state == StoreKit.PURCHASED then
            print("transaction.receipt", event.transaction.receipt)
        end
 
        if event.transaction.state == StoreKit.RESTORED then
            print("originalTransaction.identifier", event.originalTransaction.identifier)
            print("originalTransaction.date", event.originalTransaction.date)
        end
 
        -- unlock the functionality purchased by the user
    end
 
    storekit:finishTransaction(event.transaction)
end
 
 
storekit:addEventListener(Event.REQUEST_PRODUCTS_COMPLETE, onRequestProductsComplete)
storekit:addEventListener(Event.TRANSACTION, onTransaction)
 
 
storekit:requestProducts({
	"com.giderosmobile.iaptest.consumable",
	"com.giderosmobile.iaptest.nonconsumable",
})
 
stage:addEventListener(Event.MOUSE_DOWN, function()
	storekit:purchase("com.giderosmobile.iaptest.consumable", 1)
end)

Should i put event.transaction.receipt here or based on my finding, we must base64 it first?

Yes I think it should be a:

event.transaction.receipt

I just don't know what is an example of event.transaction.receipt contents? Maybe it's already encoded
