方法：createOrder(...)
行数：159-164
代码：
/** @var StoreOrderComputedServices $computedServices */
$computedServices = app()->make(StoreOrderComputedServices::class);
$priceData = $computedServices->computedOrder($uid, $userInfo, $cartGroup, $addressId, $payType, $useIntegral, $couponId, $shippingType, $isSendGift);
// 下单时以本次提交地址重新计算后的商品明细为准，避免旧 orderKey 缓存中的邮费明细落库。
$cartInfo = $priceData['cartInfo'] ?? $cartGroup['cartInfo'];
