SystemLogModel.php 为系统日志类，LogModel.php 为业务日志类。有一个全局自动根据路由写入日志(入参和响应等内容)的话更好。

<?phpnamespace common\models\common;use backend\helpers\AdminHelper;
use common\helpers\MessageHelper;
use common\models\BaseModel;class SystemLogModel extends BaseModel
{const MODULE_USER = '用户';const MODULE_ROLE = '角色';const MODULE_MENU = '菜单';const MODULE_CONFIG = '配置';const MODULE_QUEUE = '队列';const MODULE_PUSH = '推送';const MODULE_SUBJECT_MENU = '菜单';const ACTION_LOGIN = '登录';const ACTION_LOGOUT = '登出';const ACTION_NEW = '新增';const MODULE_OPTIONS = [self::MODULE_USER,self::MODULE_ROLE,self::MODULE_MENU,self::MODULE_QUEUE,self::MODULE_CONFIG,];const ACTION_OPTIONS = [self::ACTION_LOGIN,self::ACTION_LOGOUT,self::ACTION_NEW,self::ACTION_EDIT,self::ACTION_DELETE,self::ACTION_UPDATE_STATUS,self::ACTION_RE_PUSH,self::ACTION_MARK_COMPLETED,];public static function tableName(){return 'xxx_log';}public static function log($module, $action, $data){try {unset($data['password']);unset($data['confirm_password']);$log = new static();$log->module = $module;$log->data = json_encode($data, JSON_FLAG);$log->item_id = $data['item_id'] ?? '';if (empty($log->item_id)) {$log->item_id = $data['id'] ?? '';}$log->action = $action;$log->username = AdminHelper::getSessionData('username');if (empty($log->username)) {$log->username = 'console';}$log->real_name = AdminHelper::getSessionData('real_name');if (empty($log->real_name)) {$log->real_name = '系统自动';}$log->save(false);} catch (\Throwable $e) {MessageHelper::send('保存后台日志异常:'.$e->getMessage().$e->getTraceAsString().',参数:'.json_encode([$module, $action, $data], JSON_FLAG));}}
}```php
<?phpnamespace common\models\common;class LogModel extends SystemLogModel
{const MODULE_GOODS = '商品';const MODULE_PRIZE_ITEM = '奖品';const MODULE_ADMIN = '后台';const MODULE_INTEGRAL = '积分商品活动';const MODULE_DAYS_PRICE = '每日价格';const MODULE_ONLINE_CATE = '线上商品分类';const MODULE_OPTIONS = [self::MODULE_GOODS,self::MODULE_PROMOTION,self::MODULE_COUPON,self::MODULE_GOODS_LISTING,self::MODULE_CHANNEL,self::MODULE_BRAND,self::MODULE_COUNTER,self::MODULE_CLIENT,self::MODULE_ADMIN,self::MODULE_PRIZE,self::MODULE_PRIZE_ITEM,self::MODULE_ASSISTANCE];const ACTION_INVALID = '作废';const ACTION_GIFT = '赠送';const ACTION_STOCK_RESTORE = '库存修复';const ACTION_ADD_CLIENT_CODES = '批量新增渠道';const ACTION_OPTIONS = [self::ACTION_NEW,self::ACTION_EDIT,self::ACTION_DISABLED,self::ACTION_UPDATE_STATUS,self::ACTION_LISTING_UP,self::ACTION_LISTING_DOWN,self::ACTION_CHECK,self::ACTION_INVALID,self::ACTION_STOCK_RESTORE,self::ACTION_ADD_CLIENT_CODES,];public static function tableName(){return 'kld_log';}
}

使用示例：```php
LogModel::log(LogModel::MODULE_ONLINE_CATE, LogModel::ACTION_EDIT,$params);

日志存到表后可在后台做页面，方便快速查询。
