1、文件：app/services/order/StoreCartServices.php

方法：

checkLimit

2、復(fù)制代碼段，到后面截圖部位

/** @var StoreOrderCartInfoServices $orderCartServices */
			$orderCartServices = app()->make(StoreOrderCartInfoServices::class);
			/** @var StoreOrderServices $storeOrderServices */
			$storeOrderServices = app()->make(StoreOrderServices::class);
			//取消購買限購數(shù)量
			$orderDelNum = $storeOrderServices->search(['paid' => 0, 'is_del' => 1])->column('id');
			//購買數(shù)量
			$orderPayNum = $orderCartServices->search(['uid' => $uid, 'product_id' => $product_id])
				->when($orderDelNum, function ($query) use ($orderDelNum) {
					$query->whereNotIn('oid', $orderDelNum);
				})->sum('cart_num');
			//退款數(shù)量
            $orderRefundNum = $orderCartServices->sum(['uid' => $uid, 'product_id' => $product_ids], 'refund_num');
            $orderNum = $cartNum + $orderPayNum - $orderRefundNum;
            if (($num + $orderNum) > $limitInfo['limit_num']) {
                throw new ValidateException('該商品限購 ' . $limitInfo['limit_num'] . ' 件，您已經(jīng)購買 ' . $orderNum . ' 件');
            }

3、文件：app/dao/order/StoreOrderCartInfoDao.php

4、復(fù)制代碼段，到下圖截圖部位

public function search(array $where = [])
	{
		return parent::search($where);
	}

5、重啟swoole，重新設(shè)置限制在此購買測試
