-# Temp File Transfer Service
+# 临时文件传输服务
 
-A Flask-based personal temporary file sharing service with a Web UI, API access, and SQLite-backed metadata.
+基于 Flask 的个人临时文件分享服务，支持 Web 界面、API 接口和 SQLite 数据库。
 
-What it does
-- Upload files via a Web UI or an API endpoint
-- Choose an expiry: 1 hour, 24 hours, or 7 days
-- Generate a share URL (UUID) for downloaded access
-- File data stored on disk; metadata stored in SQLite
-- Web-based download page and a simple API for programmatic uploads
+## 功能介绍
+
+- 通过 Web 界面或 API 接口上传文件
+- 选择过期时间：1 小时、24 小时或 7 天
+- 生成分享链接（UUID）供下载使用
+- 文件数据存储在磁盘，元数据存储在 SQLite
+- Web 下载页面和简单的 API 接口支持程序化上传
+
+## 技术栈
 
-Tech stack
 - Flask (Python)
-- SQLite (metadata)
-- Filesystem storage for actual file data
+- SQLite (元数据存储)
+- 文件系统存储实际文件数据
 
-Local development setup
-1. Prerequisites
-- Python 3.8+ (the project currently uses Python 3.x in this environment)
+## 本地开发环境搭建
+
+### 1. 环境要求
+
+- Python 3.8+ (当前环境使用 Python 3.x)
 - pip
 
-2. Install dependencies
+### 2. 安装依赖
+
 ```bash
 pip install -r requirements.txt
 ```
 
-3. Run the server
+### 3. 运行服务
+
 ```bash
 python app.py
 ```
 
-4. Access
-- Web UI: http://localhost:5000
-- API: see /api/upload and /api/file endpoints
+### 4. 访问地址
 
-Deployment
+- Web 界面: http://localhost:5000
+- API 接口: 详见 /api/upload 和 /api/file 接口
 
-The production instance runs at:
-- **Domain**: `xiaji-temp.duckdns.org`
-- **HTTPS**: Let's Encrypt SSL with auto-renewal (certbot timer)
-- **Nginx**: reverse proxy with 500MB upload limit, 80→443 redirect
-- **Gunicorn**: 4 workers, systemd-managed
+## 部署说明
 
-Project layout
-- app.py               # Flask application
-- config.py            # Configuration constants
-- database.py          # SQLite helpers and data access
-- requirements.txt     # Python dependencies
-- templates/            # Jinja templates (index.html, download.html)
-- upload_client.py      # Simple API client example for testing
-- uploads/              # Storage for uploaded files (created at runtime)
+生产环境部署信息：
 
-Data model (SQLite)
-- Table: files
-  - id TEXT PRIMARY KEY
-  - filename TEXT
-  - filepath TEXT
-  - filesize INTEGER
-  - expiry_hours INTEGER
-  - created_at TIMESTAMP
-  - expires_at TIMESTAMP
+- **域名**: `xiaji-temp.duckdns.org`
+- **HTTPS**: Let's Encrypt SSL 证书，自动续期 (certbot timer)
+- **Nginx**: 反向代理，500MB 上传限制，80→443 自动跳转
+- **Gunicorn**: 4 个工作者进程，systemd 管理
 
-Expiry and cleanup
-- Expiry options are defined as 1h, 24h, 7d in config
-- A cleanup operation removes expired files from disk and deletes DB rows
-- Cleanup is invoked on access endpoints (and can be wired to a cron/daemon later)
+## 项目结构
 
-Traffic limits
-- Maximum file size: 500 MB
-- Per-IP daily traffic limit: 20 GB (upload + download combined)
-- IP traffic tracked in SQLite `ip_traffic` table, reset daily
+| 文件 | 说明 |
+|------|------|
+| `app.py` | Flask 应用程序主文件 |
+| `config.py` | 配置常量 |
+| `database.py` | SQLite 辅助函数和数据访问 |
+| `requirements.txt` | Python 依赖包 |
+| `templates/` | Jinja 模板 (index.html, download.html) |
+| `upload_client.py` | 简单的 API 客户端示例，用于测试 |
+| `uploads/` | 上传文件存储目录 (运行时创建) |
+| `temp_file_trans_client/` | PySide6 桌面客户端 |
 
-SSL certificate
-- Let's Encrypt certificate deployed via certbot
-- Auto-renewal via systemd timer: `certbot.timer`
-- Manual renewal test: `certbot renew --dry-run`
+## 桌面客户端
 
-Security notes
-- Do not commit secrets. Secrets should be provided via environment variables in production.
-- This repository currently avoids embedding credentials.
+使用 Python + PySide6 + PyInstaller 构建的桌面客户端，支持拖拽上传文件。
 
-Next steps (optional)
-- Add authentication for admin/API usage
-- Add rate limiting and upload size limits per user
-- Add automated tests and CI integration
+### 客户端功能
 
-License
-- MIT or your preferred license (update as needed)
+- 拖拽文件到指定区域上传
+- 点击选择文件上传
+- 显示上传进度
+- 上传成功显示分享链接
+- 支持复制链接到剪贴板
+- 可配置服务器地址
 
-API Usage (Python)
+### 运行客户端
 
-Upload a file via the API endpoint:
-
-```python
-import requests
-
-BASE_URL = "https://xiaji-temp.duckdns.org"
-
-expiry = "24h"  # 1h, 24h, 7d
-
-with open("/path/to/your/file.zip", "rb") as f:
-    resp = requests.post(
-        f"{BASE_URL}/api/upload",
-        files={"file": ("file.zip", f)},
-        data={"expiry": expiry},
-    )
-
-if resp.status_code == 200:
-    data = resp.json()
-    print(f"Share URL: {data['share_url']}")
-    print(f"File ID: {data['id']}")
-    print(f"Size: {data['filesize']} bytes")
-else:
-    print(f"Upload failed: {resp.json()['error']}")
+```bash
+cd temp_file_trans_client
+pip install -r requirements.txt
+python main.py
 ```
 
-Response format:
+### 打包为 exe
+
+```bash
+cd temp_file_trans_client
+pip install pyinstaller
+pyinstaller build.spec
+```
+
+打包后的可执行文件位于 `dist/temp_file_trans_client.exe`
+
+## 数据模型 (SQLite)
+
+**files 表结构：**
+
+| 字段 | 类型 | 说明 |
+|------|------|------|
+| id | TEXT PRIMARY KEY | 文件唯一标识 (UUID) |
+| filename | TEXT | 原始文件名 |
+| filepath | TEXT | 文件存储路径 |
+| filesize | INTEGER | 文件大小 (字节) |
+| expiry_hours | INTEGER | 过期时间 (小时) |
+| created_at | TIMESTAMP | 创建时间 |
+| expires_at | TIMESTAMP | 过期时间 |
+
+## 过期清理
+
+- 过期选项在 config 中定义为 1h、24h、7d
+- 清理操作会删除过期文件并清理数据库记录
+- 访问接口时自动触发清理 (后续可配置 cron/定时任务)
+
+## 流量限制
+
+- 最大文件大小：500 MB
+- 单 IP 每日流量限制：20 GB (上传 + 下载合计)
+- IP 流量记录在 SQLite `ip_traffic` 表中，每日重置
+
+## SSL 证书
+
+- 使用 Let's Encrypt 证书，通过 certbot 部署
+- 自动续期通过 systemd timer: `certbot.timer`
+- 手动测试续期: `certbot renew --dry-run`
+
+## 安全说明
+
+- 请勿提交密钥等敏感信息。生产环境应通过环境变量提供
+- 当前仓库未嵌入任何凭证
+
+## API 接口说明
+

+
+## 2. 技术栈
+
+| 组件 | 技术 |
+|------|------|
+| GUI框架 | PySide6 |
+| HTTP客户端 | requests |
+| 打包工具 | PyInstaller |
+| Python版本 | 3.8+ |
+
+## 3. 功能列表
+
+### 3.1 服务器配置
+- 顶部输入框配置服务器地址
+- 默认值: `http://localhost:5000`
+- 保存到本地配置文件
+
+### 3.2 文件上传
+- 拖放文件到拖放区域上传
+- 点击拖放区域选择文件
+- 显示上传进度条
+- 支持过期时间选择: `1h`, `24h`, `7d`
+
+### 3.3 结果展示
+- 上传成功后显示分享链接
+- 点击链接复制到剪贴板
+- 显示文件ID和文件名
+
+### 3.4 错误处理
+- 网络错误提示
+- 服务器返回错误展示
+- 文件大小超限提示（参考服务器500MB限制）
+
+## 4. UI设计
+
+### 4.1 窗口布局
+```
+┌──────────────────────────────────────┐
+│  服务器: [http://localhost:5000]  [保存] │  ← 配置栏 (40px)

+
+## 5. API交互
+
+### 5.1 上传接口
+参考 `upload_client.py`，使用 `requests.post` 上传：
+
+```
+POST /api/upload
+Content-Type: multipart/form-data
+
+file: <binary>
+expiry: 1h|24h|7d
+```
+
+**成功响应 (200)**:
+```json
+{
+  "id": "uuid",
+  "filename": "example.pdf",
+  "filesize": 1234567,
+  "expiry_hours": 24,
+  "share_url": "http://server/file/<id>"
+}
+```
+
+**错误响应 (400/429/500)**:
+```json
+{
+  "error": "错误描述"
+}
+```
+
+### 5.2 链接格式
+```
+分享链接: {服务器地址}/file/{file_id}
+直接下载: {服务器地址}/download/{file_id}
+```
+
+## 6. 文件结构
+
+```
+temp_file_trans_client/
+├── main.py           # 入口，创建应用和主窗口
+├── ui.py             # UI组件和布局

+```
+
+## 7. 打包配置
+
+### PyInstaller spec
