JSPM – itunes-validation@0.1.6

Package Exports

itunes-validation

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (itunes-validation) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

In App Usage

struct Receipt: Decodable {
    var receipt: [String:String]
    var status: Int
}

func obfuscatedValidationMethod() {
    let receiptURL = Bundle.main.appStoreReceiptURL
    let receiptData = NSData(contentsOf: receiptURL!)
    let base64Receipt = receiptData?.base64EncodedString(options: .endLineWithLineFeed)
    let queryItems = [URLQueryItem(name: "receipt", value: base64Receipt)]
    var valUrl = URLComponents(string: "<# https://appName.herokuapp.com #>/0.1/sandbox")
    valUrl?.queryItems = queryItems
    let request = URLRequest(url: valUrl!.url!)

    let session = URLSession.shared
    let task = session.dataTask(with: request) { (data, response, error) in
        guard let responseData = data else {
            return
        }
        let decoder = JSONDecoder()
        do {
            let decodedReceipt = try decoder.decode(Receipt.self, from: responseData)
            if decodedReceipt.status == 1 {
                // Do something with invalid receipt.
            }
        } catch {
            // Handle error.
        }
    }

    task.resume()
