你们是怎么解决服务端重复更新的问题了

首先不考虑前端的，完全隔离
如果是单纯服务端你们是怎么解决的

public function update(RechargeRecordRequest $request, RechargeRecord $rechargeRecord): RechargeRecordResource
    {
        if($rechargeRecord->status != 'pending')
        {
            throw new InvalidRequestException("不能重复更新");
        }

        $user = auth()->user();

        if ($request->status == 'approved')
        {
            $balance = $user->balance + $request->charges;

            DB::beginTransaction();
            try {

                $this->users->updateBalance($user, $balance); // 乐观锁更新

                // 写入财务日志
                $user->financialRecords()->create(['type' => FinancialType::recharge, 'charges' => $request->charges, 'description' => sprintf('银行转帐', $user->phone)]);

                $rechargeRecord->status = 'approved';
                $rechargeRecord->auditor = $user->id;
                $rechargeRecord->description = $request->description;
                $rechargeRecord->note = $request->note;
                $rechargeRecord->save(); //更新状态是没有采用乐观锁的，因为一旦采用乐观锁，下面还要return，如果用乐观锁就还的再刷新一次

                DB::commit();
            }catch (InvalidRequestException $e) {
                DB::rollBack();
                throw $e;
            }
        }elseif($request->status == 'rejected')
        {
            $rechargeRecord->status = 'rejected';
            $rechargeRecord->auditor = $user->id;
            $rechargeRecord->description = $request->description;
            $rechargeRecord->note = $request->note;
            $rechargeRecord->save();
        }

        return new RechargeRecordResource($rechargeRecord);
    }
