/**
|
||||
* 使用说明:
|
||||
*
|
||||
* 1. 在需要记录操作日志的控制器方法前添加 createOperationLogger 中间件
|
||||
* 2. 配置中间件参数:
|
||||
* - moduleName: 模块名称（如：用户管理、农场管理）
|
||||
* - tableName: 数据表名（如：users、farms）
|
||||
* - getRecordId: 获取记录ID的函数
|
||||
* - getOperationDesc: 获取操作描述的函数
|
||||
* - getOldData: 获取操作前数据的函数（可选）
|
||||
* - getNewData: 获取操作后数据的函数（可选）
|
||||
*
|
||||
* 3. 操作日志会自动记录以下信息:
|
||||
* - 操作用户信息（从req.user获取）
|
||||
* - 操作类型（CREATE/UPDATE/DELETE）
|
||||
* - 操作描述
|
||||
* - 数据变化（操作前后的数据）
|
||||
* - 请求信息（IP、URL、方法等）
|
||||
* - 响应信息（状态码、执行时间等）
|
||||
*
|
||||
* 4. 对于批量操作，可以使用 createBatchOperationLogger 记录多个操作
