操作步驟如下：

一、打開app/Http/Service/Client/ContractService.php 文件, 修改以下三處位置。

1.1 找到 reloadStatus 方法, 位于843行左右，替換:

    public function reloadStatus(int $id, mixed $contract = null): void
    {
        $contract = $contract ?: $this->dao->get($id);
        if ($contract->is_abnormal) {
            $contract->contract_status = '3';
        } else {
            $status = '1';
            $tz     = config('app.timezone');
            $now    = Carbon::now($tz)->toDateString();
            if ($contract->start_date && Carbon::parse($contract->start_date, $tz)->gt($now)) {
                $status = '0';
            }

            if ($contract->end_date && Carbon::parse($contract->end_date, $tz)->lt($now)) {
                $status = '2';
            }
            $contract->contract_status = $status;
        }

        $contract->save();
    }

1.2 找到 updateContract 方法, 位于169行左右:

替換行:

 $data['contract_status'] = $info->is_abnormal ? '3' : $this->getStatus($data);

1.3 找到 statusTimer 方法, 位于828行左右，替換:

    public function statusTimer(): void
    {
        $now = Carbon::now(config('app.timezone'))->toDateString();
        $this->dao->update(['start_date_gt' => $now, 'contract_status_lt' => '2'], ['contract_status' => '1']);
        $this->dao->update(['end_date_lt' => $now, 'contract_status_lt' => '3'], ['contract_status' => '2']);
    }

二、打開app/Http/Service/Client/ClientBillService.php 文件， 找到 contractPrice 方法，位于1113行左右，替換：

    private function contractPrice(int $cid, $contract = null): bool
    {
        $contractService = app()->get(ContractService::class);
        if (! $contract) {
            $contract = $contractService->get($cid);
        }
        if (! $contract) {
            throw $this->exception('合同信息獲取異常');
        }
        $contract->received = max($this->dao->getSum(['cid' => $cid, 'types' => -1]), 0);
        $paymentAmount      = max($this->dao->getSum(['cid' => $cid, 'types' => 0]), 0);
        $contract->surplus  = max(bcsub((string) $contract->contract_price, (string) $paymentAmount, 2), 0);
        return true;
    }

三、打開app/Http/Model/Client/Contract.php 文件，新加方法：

    /**
     * end_date lt 作用域
     * @param $query
     * @param $value
     * @return void
     */
    public function scopeEndDateLt($query, $value): void
    {
        if ($value != '') {
            $query->whereDate('end_date', '<', $value);
        }
    }

保存文件后并重啟守護(hù)進(jìn)程。
