我如何使用 Swift 将收据数据发送到 Node.js 服务器

Question

我目前正在尝试验证 iOS 中的 IAP 用户订阅收据。首先，我发出一个 post 请求，从当前存储在 Bundle.main.appStoreReceiptURL 中的收据中获取收据数据。我能够在我的服务器中使用此收据数据来验证收据是否运作良好。然而，此收据数据字符串在特定于特定用户的 Node 中进行了硬编码。根据要验证的任何用户，我如何才能将此收据字符串发送到我的服务器以获取任何收据。这是我的 Swift 和服务器代码。 Apple 在文档中说

To retrieve the receipt data, use the appStoreReceiptURL method of NSBundle to locate the app’s receipt, and then read the entire file. Send this data to your server—as with all interactions with your server, the details are your responsibility.

我想获取收据数据并将其发送到我的服务器。

func getReceipt() {
    if let receiptUrl = receiptUrl {
        do {
            let purchaseReceipt = try Data(contentsOf: receiptUrl)
            self.validatePurchaseReceipt(pReceiptData: purchaseReceipt)
        } catch {
            let receiptRefreshRequest = SKReceiptRefreshRequest(receiptProperties: nil)
            receiptRefreshRequest.delegate = self
            receiptRefreshRequest.start()
        }
    }
}

func validatePurchaseReceipt(pReceiptData: Data) {
    let base64encodedReceipt = pReceiptData.base64EncodedString()
    let secretKey = "myAppstoreConnectSecretKey"
    let requestReceiptDict = ["receipt-data": base64encodedReceipt, "password": secretKey]
    guard JSONSerialization.isValidJSONObject(requestReceiptDict) else { return }
    do {
        let data = try JSONSerialization.data(withJSONObject: requestReceiptDict)
        let validationString = "https://sandbox.itunes.apple.com/verifyReceipt"
        guard let validationUrl = URL(string: validationString) else { return }
        let session = URLSession(configuration: .default)
        var request = URLRequest(url: validationUrl, cachePolicy: .reloadIgnoringLocalCacheData)
        request.httpMethod = "POST"
        let task = session.uploadTask(with:request, from: data) { (data, response, error) in
            guard let data = data, error == nil else { return }
            do {
                let purchaseReceiptJSON = try JSONSerialization.jsonObject(with: data, options: .allowFragments)
                print("Success retrieved json:\(purchaseReceiptJSON)")
            } catch let error {
                print(error)
            }
        }
        task.resume()
    } catch let error {
        print(error)
    }
}

这是我的服务器代码

const express = require('express');
const requirePromise = require('request-promise');
const app = express();

let verificationURL = 'https://sandbox.itunes.apple.com/verifyReceipt';
let secretKey = 'myAppstoreConnectSecretKey';
let receiptData = 'MIIntgYJKoZIhvcNAQcCoIInpzCCJ6MCAQExCzAJBgUrDgMCGgUAMIIXVwYJKoZIhvcNAQcBoIIXSASCFetc'
const options = {
  url: verificationURL,
    method: 'POST',
    headers: {
    'User-Agent': 'Request-Promise',
        'Content-Type': 'application/x-www-form-urlencoded',
    },
    json: true
};

options.form = JSON.stringify({
    'receipt-data': receiptData,
    'password': secretKey
});

requirePromise(options).then((resData) => {
    console.log(resData);
    return resData;
}).catch(function (error) {
    console.log(error);
});

如果您打算使用您的服务器来验证收据（您应该这样做），那么 validatePurchaseReceipt 方法应该调用您的服务器，而不是 /verifyReceipt 端点。收据数据被传递到您的服务器，就像您使用 requestReceiptDict.

一样

此外，secretKey 应该在您的服务器上进行硬编码 - 而不是在客户端的任何地方。
