        // 检查请求方法是否为 POST
        if ($request->isPost()) {

            // 解密 resource 字段中的数据
            if (isset($notifyData['resource'])) {
                $resource = $notifyData['resource'];
                $decryptedResource = $this->decryptResource($resource);
                Log::info("解密后的数据");
                Log::info(json_encode($decryptedResource));
                if ($decryptedResource === false) {

            return error('请求方法不正确, 必须是 POST 方法');
        }
    }`

2.设置数据库操作的方法：

private static function setNotifyAct($notifyData)
    {
        Log::info("setNotifyAct方法执行数据库操作");

        $data = [
            'status' => 1,
            'w_transaction_id' => $notifyData['resource']['transaction_id'],
            'payment_status' => 1,
            'payment_type' => 1,
            'w_payment_time' => date('Y-m-d H:i:s'),
            'w_trade_type' => $notifyData['resource']['trade_type'], // 保留最后一次赋值
            'w_notify_content' => json_encode($notifyData),
        ];

        // 更新订单状态
        Log::info("更新订单状态结果");
        $res = orderService::updateOrderByField('sys_order_no',$notifyData['resource']['out_trade_no'], $data);
        if ($res) {
            if (strpos($notifyData['resource']['out_trade_no'], 'SDCQ') !== false) {
                // 抽取订单支付1.只更新订单状态
                Log::info("抽取订单支付成功out_trade_no: " . $notifyData['resource']['out_trade_no']);
                return ['status' => 1, 'msg' => '更新订单成功'];
            } elseif (strpos($notifyData['resource']['out_trade_no'], 'SDCZ') !== false) {
                // 充值,这里是更新订单和用户余额
                $user_id = user_id(true);
                $order_info = orderService::getUserPrice($notifyData['resource']['attach']);
                Log::info("获取用户订单信息");
                Log::info(json_encode($order_info)); // 将数组转换为字符串

                if (empty($order_info) || !isset($order_info['price'])) {
                    Log::error("获取用户订单信息失败attach: " . $notifyData['resource']['attach']);
                    return ['status' => 0, 'msg' => '获取用户订单信息失败'];
                }

                $res1 = userService::updateUserBalance($user_id, $order_info['price']);
                Log::info("更新用户余额结果result: " . json_encode($res1)); // 将数组转换为字符串

                if ($res1['status'] == 1) {
                    Log::info("用户余额更新成功user_id: " . $user_id . " amount: " . $order_info['price']);
                    return ['status' => 1, 'msg' => '更新用户余额成功'];
                } else {
                    Log::error("用户余额更新失败user_id: " . $user_id . " amount: " . $order_info['price'] . " result: " . json_encode($res1)); // 将数组转换为字符串
                    return ['status' => 0, 'msg' => '更新用户余额错误'];
                }
            }
        } else {
            Log::error("更新订单状态失败out_trade_no: " . $notifyData['resource']['out_trade_no'] . " result: " . json_encode($res)); // 将数组转换为字符串
            return ['status' => 0, 'msg' => '更新订单错误'];
        }
    }

3.解密源数据

/**
     * 解密资源数据
     *
     * @param array $resource 资源数据
     * @return array 解密后的数据
     */
    private function decryptResource(array $resource): array
    {
        // 获取解密所需的参数
        $algorithm = $resource['algorithm']; // 加密算法
        $ciphertext = $resource['ciphertext']; // 密文
        $associatedData = $resource['associated_data']; // 关联数据
        $nonce = $resource['nonce']; // 随机数

        // 使用 API v3 密钥进行解密
        $key = $this->apiV3Key;

        // 创建 AES-GCM 解密器
        $aesGcm = new AesGcm();

        // 解密数据
        $decryptedData = $aesGcm::decrypt($ciphertext, $key, $nonce, $associatedData);

        // 解析解密后的 JSON 数据
        $decryptedData = json_decode($decryptedData, true);

        return $decryptedData;
    }

5.调用回调方法

public function wxpayNotify(Request $request){
        $WxPay = new WxPay();
        $response = $WxPay->notify($request);

        // 返回响应给微信服务器
        return $response;
    }
