苹果内购支付 Java 接口

 支付流程，APP支付成功后 前端调用后端接口，后端接口将前端支付成功后拿到的凭据传给苹果服务器检查，如果接口返回成功了，就视为支付。

代码，productId就是苹果开发者后台提前设置好的 产品id

    public CommonResult<String> appleRecharge(AppleRechargeVo request) {
        String receipt = request.getReceipt();
        String orderId = request.getOrderId();

        log.info("receipt -- {}", receipt);
        log.info("orderId -- {}", orderId);

        // 构造 Apple 验证请求体
        JSONObject body = new JSONObject();
        body.put("receipt-data", receipt);
        // body.put("password", "你的共享密钥（可选，用于自动订阅）");

        // 先请求正式环境
        String response = HttpUtil.post("https://buy.itunes.apple.com/verifyReceipt", body.toJSONString());

        JSONObject jsonResponse = JSONObject.parseObject(response);

        // 状态码为21007时说明是沙盒订单
        if ("21007".equals(jsonResponse.getString("status"))) {
            response = HttpUtil.post("https://sandbox.itunes.apple.com/verifyReceipt", body.toJSONString());
            jsonResponse = JSONObject.parseObject(response);
        }

        log.info("APPLE 接口返回值 -- {}", response);


        // 根据验证状态处理逻辑
        if (0 == jsonResponse.getInteger("status")) {
            // log.info("状态成功！！！");

            // 验证成功，做后续订单处理

            // 取出 in_app 数组
            JSONArray inAppArray = jsonResponse
                    .getJSONObject("receipt")
                    .getJSONArray("in_app");
            // log.info("inAppArray ！！！{}", inAppArray);

            if (inAppArray != null && !inAppArray.isEmpty()) {
                JSONObject firstPurchase = inAppArray.getJSONObject(0);
                String productId = firstPurchase.getString("product_id");
                String transactionId = firstPurchase.getString("transaction_id");

                log.info("productId ！！！{}", productId);
                log.info("transactionId ！！！{}", transactionId);

                BigDecimal amount = null;

                }


                // 加余额
