-# 日志系统文档
-
-## 概述
-
-本项目实现了统一的后端日志系统，为所有接口提供了详细的日志记录功能，包括请求、响应、错误等状态。
-
-## 日志系统结构
-
-### 1. logger.js
-- 统一日志管理模块
-- 支持多种日志级别：ERROR, WARN, INFO, DEBUG
-- 支持控制台和文件双重输出
-- 包含HTTP请求专用日志方法
-
-### 2. 日志文件位置
-- 存储在 `server/logs/` 目录
-- 按日期命名：`server-YYYY-MM-DD.log`
-- JSON格式便于查询和分析
-
-## 日志级别
-
-- `ERROR`: 错误和异常情况
-- `WARN`: 警告和潜在问题
-- `INFO`: 重要操作和状态信息
-- `DEBUG`: 详细调试信息
-
-## 接口日志详情
-
-### 1. 对话接口 (`/api/chat-ui/chat`)
-- 记录请求代理开始和结束
-- 记录目标API响应状态
-- 记录代理错误
-
-### 2. 模型列表接口 (`/api/chat-ui/models`)
-- 记录请求基本信息
-- 记录返回的模型数量
-
-### 3. 对话管理接口 (`/api/chat-ui/conversations/*`)
-- 记录操作类型（获取/创建/删除）
-- 记录对话ID
-- 记录操作结果
-
-### 4. 文件上传接口 (`/api/chat-ui/upload`)
-- 记录上传文件信息（名称、大小、类型）
-- 记录上传结果和生成的URL
-
-### 5. 停止生成接口 (`/api/chat-ui/stop/*`)
-- 记录停止请求的ID
-- 记录操作结果
-
-### 6. HTTP通用日志
-- 记录所有请求的方法、URL、状态码
-- 记录请求耗时
-- 记录客户端IP和User-Agent
-- 根据状态码自动分类日志级别
-
-## 使用方法
-
-### 环境变量
-```bash
-LOG_LEVEL=DEBUG  # 设置日志级别，默认为INFO
-```
-
-### 在代码中使用
-```javascript
-const { logger } = require('./logger');
-
-logger.info('Some info message', { additional: 'data' });
-logger.error('Error occurred', { error: error.message });
-logger.debug('Debug info', { variable: value });
-```
-
-## 日志示例
-
-### HTTP请求日志
-```json
-{
-  "timestamp": "2026-03-03T03:26:58.631Z",
-  "level": "INFO",
-  "message": "HTTP GET /api/chat-ui/models 200 15ms",
-  "method": "GET",
-  "url": "/api/chat-ui/models",
-  "statusCode": 200,
-  "duration": "15ms",
-  "userAgent": "Mozilla/5.0...",
-  "ip": "::1"
-}
-```
-
-### 特定接口日志
-```json
-{
-  "timestamp": "2026-03-03T03:27:12.123Z",
-  "level": "INFO",
-  "message": "Successfully uploaded file",
-  "filename": "1642342342-file.jpg",
-  "originalName": "file.jpg",
-  "url": "http://localhost:3000/uploads/1642342342-file.jpg",
-  "size": 123456
