未定义的属性：laravel API 的 stdClass::$id

Question

我在 Laravel 上使用 API 的查询构建器执行此操作$shipments = DB::table('shipment_batches')            ->select(                "shipments.id as shipment_id",                "shipments.fulfillment_id",                "shipments.shipped_address_id",                "shipments.courrier_id",                "shipments.status",                "shipments.is_intro",                "shipments.is_express",                "shipments.shipment_batch_id",                "shipments.intro_shipment_date",                "shipments.intro_shipped_at",                "shipments.tracking_number",                "shipments.is_gift",                "shipments.ship_unit",                "shipments.shipment_notes",                "shipments.is_one_time_product",                "shipments.one_time_product_shipment_date",                "shipments.one_time_product_shipped_at",                "shipments.shipment_options",                "shipments.is_migrated",                "shipments.migration_has_error",                "shipments.in_process_date",                "shipments.shipment_date_at",                "shipments.link",                )            ->join('shipments', 'shipments.shipment_batch_id', '=', 'shipment_batches.id')            ->join('fulfillments', 'fulfillments.id', '=', 'shipments.fulfillment_id')            ->join('subscriptions', 'subscriptions.id', '=', 'fulfillments.subscription_id')            ->whereMonth('shipment_batches.shipment_date', '>', date('m'))            ->whereYear('shipment_batches.shipment_date', '=', date('Y'))            ->where('subscriptions.user_id', $id)            ->orderBy('shipment_batches.id', 'ASC')            ->get();我只是删除了其他数组返回值以简化集合。并在 API 上作为 json 返回之前添加hashed_id并padded_id修改结果我收到这个错误未定义的属性：stdClass::$id是否可以从查询构建器中创建集合？如何？
