从堆栈溢出上的所有其他答案中，我没有找到此特定问题的答案。
我正在使用SKReceiptRefreshRequest还原购买。我正在使用沙箱帐户。我有以下代码:
let request = SKReceiptRefreshRequest()
request.delegate = self
request.start()
结果是调用SKRequestDelegate协议的requestDidFinish时。我返回的请求的receiveProperties属性为nil。我该怎么解释？文档(Refreshing the App Receipt)说要检查收据，但似乎没有要检查的东西。
这是我的代码，当我假设以零净值的回执来获取请求意味着我收到了回执时。
extension SettingsTableViewController: SKRequestDelegate {
func requestDidFinish(_ request: SKRequest) {
print("requestDidFinish")
print("request=", request)
if let receiptRefreshRequest = request as? SKReceiptRefreshRequest {
print("receipt properties=", receiptRefreshRequest.receiptProperties as Any)
}
if iCloudAvailable() {
ubiquitousKeyValueStore.set(true, forKey: UbiquitousKeys.iMessageExtension)
let alertMessage = "iMessage Saved Messages has been restored."
let alert = UIAlertController(title: nil, message: alertMessage, preferredStyle: .alert)
let actionOK = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alert.addAction(actionOK)
present(alert, animated: true, completion: nil)
}
}
func request(_ request: SKRequest, didFailWithError error: Error) {
print("requst(_:didFailWithError:)")
if let receiptRefreshRequest = request as? SKReceiptRefreshRequest {
print("receipt properties=", receiptRefreshRequest.receiptProperties as Any)
} else {
print("request=", request)
}
print("error=", error)
let alertMessage = "There are no purchases to restore."
let alert = UIAlertController(title: nil, message: alertMessage, preferredStyle: .alert)
let actionOK = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alert.addAction(actionOK)
present(alert, animated: true, completion: nil)
}
}

我找到了该网页的答案。苹果的文档没有在需要的地方显示。

func validateReceipt() {
let recURL = Bundle.main.appStoreReceiptURL!
let contents = NSData(contentsOf: recURL)
let receiptData = contents!.base64EncodedString(options: NSData.Base64EncodingOptions(rawValue: 0))
print(receiptData)
let requestContents = ["receipt-data" : receiptData]
print(requestContents)
let requestData = try? JSONSerialization.data(withJSONObject: requestContents, options: [])
print(requestData)

let request = NSMutableURLRequest(url: url! as URL)
request.httpMethod = "POST"
request.httpBody = requestData
let task = URLSession.shared.dataTask(with: request as URLRequest, completionHandler: {data, response, error -> Void in

catch let error as NSError {

task.resume()
