【问题描述】：

现在我正在使用 Flutter 开发 ios 应用内购买。这是客户购买成功时我的验证码截图：

void _listenToPurchaseUpdated(List<PurchaseDetails> purchaseDetailsList, Context<PayState> ctx) 
  purchaseDetailsList.forEach((PurchaseDetails purchaseDetails) async 
    if (purchaseDetails.status == PurchaseStatus.pending) 
      RestLog.logger("PurchaseStatus pending..." + ctx.state.payModel.isAvailable.toString());
      _showPendingUI(ctx);
     else 
      if (purchaseDetails.status == PurchaseStatus.error) 
        RestLog.logger("PurchaseStatus error");
        _handleError(purchaseDetails.error!, ctx);
       else if (purchaseDetails.status == PurchaseStatus.purchased || purchaseDetails.status == PurchaseStatus.restored) 
        RestLog.logger("purchase successful trigger verify");
        PayVerifyModel payVerifyModel =
            PayVerifyModel(orderId: purchaseDetails.purchaseID, receipt: purchaseDetails.verificationData.serverVerificationData, isSandBox: true);
        Pay.verifyUserPay(payVerifyModel);
      
      if (purchaseDetails.pendingCompletePurchase) 
        await InAppPurchase.instance.completePurchase(purchaseDetails);
      
    
  );

问题是我不知道支付环境是哪个环境，现在我正在测试所以我通过了 isSandBox 是真的。如何从当前运行的上下文中知道 isSandBox？我应该怎么做才能让它充满活力？

***.com/questions/49707028/… 解决了您的问题吗？

不，我想知道 isSandBox 的状态。 @Muhtar

为什么不使用发布模式和调试模式？我看不到重点抱歉

这是苹果沙盒状态探测，有时在沙盒付费模式下也有发布模式。 @Muhtar

【参考方案1】：

其实你不需要关心环境是沙箱还是生产环境，你总是可以先使用生产URL，如果在沙箱中生成recipt，服务器将返回21007，在收到21007代码后，你可以再次尝试验证在沙盒中：

private static JSONObject validateApplePay(BuySuccessRequest request, String url) 
        try 
            HttpsURLConnection connection = (HttpsURLConnection) new URL(url).openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);
            connection.setAllowUserInteraction(false);
            PrintStream ps = new PrintStream(connection.getOutputStream());
            // Base64.Encoder encoder = Base64.getEncoder();
            // String base64String = encoder.encodeToString(request.getReceipt().getBytes(StandardCharsets.UTF_8));
            ps.print("\"receipt-data\": \"" + request.getReceipt() + "\"");
            ps.close();
            BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String str;
            StringBuffer sb = new StringBuffer();
            while ((str = br.readLine()) != null) 
                sb.append(str);
            
            // String encodeToString = Base64.getEncoder().encodeToString("Test".getBytes());
            br.close();
            String resultStr = sb.toString();
            JSONObject result = JSONObject.parseObject(resultStr);
            if (result != null && result.getInteger("status").intValue() == ApplePayVerifyResponseType.SANDBOX_SEND_TO_PRODUCTION.getKey().intValue()) 
                return validateApplePay(request, SAND_BOX_VERIFY_URL);
            
            return result;
         catch (Exception e) 
            log.error("Validate pay failed", e);
        
        return null;
    

这是苹果的advice。
