验证 iOS 应用内购买收据始终返回错误 21002

Question

我正在服务器端验证我的消费品应用内购买。

也就是说，我通过以下方式从客户端获取收据：

    .onChange(of: self.storeObserver.paymentStatus) { status in
        switch status {
        case .purchasing:
            print("Payment status: purchasing")
        case .failed:
            self.creatingGame = false
            print("Payment status: failed")
        case .deferred:
            print("Payment status: deferred")
        case .restored:
            print("Payment status: restored")
        case .purchased:
            // Get the receipt if it's available
            if Bundle.main.appStoreReceiptURL == nil {
                print("appStoreReceiptURL is nil")
            }
            if let appStoreReceiptURL = Bundle.main.appStoreReceiptURL,
                FileManager.default.fileExists(atPath: appStoreReceiptURL.path) {
                do {
                    let receiptData = try Data(contentsOf: appStoreReceiptURL, options: .alwaysMapped)

                    let receiptString = receiptData.base64EncodedString(options: [])
                    print("receiptString: \(receiptString)")
                    // Read receiptData
                    createGame(receiptString: receiptString)
                }
                catch { print("Couldn't read receipt data with error: " + error.localizedDescription) }
            }
            
            print("Payment status: purchased")
        default:
            print("Payment status: default")
        }
    }

private func createGame(receiptString: String){
    let data: [String:Any?] = [
        "gameName": self.gameName,
        "receipt": receiptString
    ]
    callFunction(name: "validateReceipt", data: data){ result, err in
    }

print("receiptString: (receiptString)") 打印以下内容：

然后将收据字符串发送到服务器：

exports.validateReceipt = functions.https.onCall(async (data, context) => {
  if (!context.auth) {
    throw new functions.https.HttpsError('permission-denied', 'The function must be called while authenticated.');
  }
  if (!data.receipt) {
    throw new functions.https.HttpsError('permission-denied', 'receipt is required');
  }
  // Now we fetch the receipt from Apple
  let body = {
    'receipt-data': data.receipt,
    // 'password': 'MY_SECRET_PASSWORD', // Not needed for Consumable IAP's
    'exclude-old-transactions': true
  };
  const options = {
    method: 'post',
    body: JSON.stringify(body),
    headers: {'Content-Type': 'application/json'},
  };
  return validateReceiptData('https://buy.itunes.apple.com/verifyReceipt', options, data, context);
});

function validateReceiptData(url, options, data, context) {
    var retries = 0

  return fetch(url, options).then(result => {
    return result.json();
      }).then(data => {
        if (data.status === 21007 && retries === 0) {
            retries += 1
          // Retry with sandbox URL
          console.log("Try sandbox URL");
          return validateReceiptData('https://sandbox.itunes.apple.com/verifyReceipt', options, data, context);
        }
        console.log(`data.status: ${data.status}`); // prints status code 21002
        // Process the result
        if (data.status !== 0) {
            console.log("The status code is not 0, so the receipt is invalid"); // function returns here
          return false;
        }
        const latestReceiptInfo = data.latest_receipt_info[0];
        console.log(`Receipt data is valid: ${latestReceiptInfo}`);
        if (data.type === "join"){
            return joinGame(data, context)
        } 
        else if (data.type === "create"){
            return createGame(data, context)
        }
        return 400;
      });
}

如您所见，上面的代码尝试生产

verifyReceipt

端点，如果失败并出现沙箱错误 (21007)，它将尝试沙箱端点。然而，它从不尝试沙箱端点，因为第一次尝试时出现了不同的错误：

21002
The data in the receipt-data property was malformed or the service experienced a temporary issue. Try again.

我不知道为什么会出现这个错误。我正在沙箱中测试这是否有任何区别。

知道为什么我总是收到此错误吗？

编辑：我已经连续 3 天遇到同样的错误，不断进行测试，尝试了所有方法，但每次仍然得到 21002。我已经彻底迷失了。

Answer 1

看起来您正在尝试在模拟器中使用 storekit 本地测试环境验证收据（在 wwdc2020 上提出），对吧？我的意思是，您以这种方式在应用程序中获得收据，无论您是否使用应用程序或某些单独的后端应用程序的 api 调用来检查此收据（是的，我已检查）

如果是这样，它将不起作用

您应该在没有此新功能的情况下完成所有操作，就像 13 及以下版本一样（通过在 appstoreconnect 等中创建产品），这样收据验证就可以正常工作。

Answer 2

首先，你的收据肯定是格式错误的，21002状态码意味着它格式错误。您也可以在这里查看，https://www.revenuecat.com/apple-receipt-checker。

你的 swift 和 js 代码似乎 100% 合法，所以不用担心！

问题可能是您的收据文件已损坏，您可以从设备中完全删除该应用程序并重新安装吗？

或者在不同的设备上尝试。

Answer 3

我有同样的问题，并且犯了一个错误：从 iTunes 帐户同步包后，我忘记在编辑方案中选择“无”。
