### 技术栈
| 组件 | 技术 | 版本 | 用途 |
|-----|------|------|------|
| 异步框架 | asyncio + aiohttp | 3.9.0+ | 高性能并发下载 |
| 文件IO | aiofiles | 23.2.1+ | 异步文件操作 |
| 数据库 | aiosqlite | 0.19.0+ | 异步SQLite |
| CLI界面 | Rich | 13.7.0+ | 美观的终端界面 |
| 配置 | PyYAML | 6.0.1+ | YAML配置解析 |
| 时间处理 | python-dateutil | 2.8.2+ | 日期时间工具 |
## 设计模式应用
### 1. 模板方法模式
**位置**: `core/downloader_base.py`
```python
class BaseDownloader(ABC):
async def download(self, parsed_url):
# 定义下载流程模板
1. 解析URL
2. 获取内容列表
3. 过滤和限制
4. 并发下载
```
### 2. 工厂模式
**位置**: `core/downloader_factory.py`
根据URL类型自动创建对应的下载器
### 3. 策略模式
**位置**: 各个下载器实现
不同类型内容使用不同的下载策略
### 4. 单例模式
**位置**: `utils/logger.py`
日志器确保全局唯一实例
## 核心功能说明
### 1. 配置管理
**多层配置优先级**:
```
命令行参数 > 环境变量 > 配置文件 > 默认配置
```
**配置文件示例**:
```yaml
link:
- https://www.douyin.com/user/xxxxx
path: ./Downloaded/
cookies:
msToken: xxx
ttwid: xxx
odin_tt: xxx
number:
post: 1
database: true
```
### 2. Cookie管理
- JSON格式本地存储
- 自动验证必需字段
- 支持多种配置方式
### 3. 数据库设计
**aweme表** - 作品记录
```sql
CREATE TABLE aweme (
id INTEGER PRIMARY KEY,
aweme_id TEXT UNIQUE,
aweme_type TEXT,
title TEXT,
author_id TEXT,
author_name TEXT,
create_time INTEGER,
download_time INTEGER,
file_path TEXT,
metadata TEXT
)
```
**download_history表** - 下载历史
```sql
CREATE TABLE download_history (
id INTEGER PRIMARY KEY,
url TEXT,
url_type TEXT,
download_time INTEGER,
total_count INTEGER,
success_count INTEGER,
config TEXT
)
```
### 4. 下载流程
```
1. 配置加载
↓
2. Cookie初始化
↓
3. URL解析
↓
4. 创建下载器
↓
5. 获取内容列表
↓
6. 应用过滤规则
↓
7. 并发下载
↓
8. 保存文件
↓
9. 更新数据库
↓
10. 显示结果
```
### 5. 文件组织
**标准模式** (folderstyle=true):
```
Downloaded/
└── [作者名]/
└── post/
└── [标题]_[ID]/
├── [标题]_[ID].mp4
├── [标题]_[ID]_cover.jpg
├── [标题]_[ID]_music.mp3
└── [标题]_[ID]_data.json
```
**简化模式** (folderstyle=false):
```
Downloaded/
└── [作者名]/
└── post/
├── [标题]_[ID].mp4
├── [标题]_[ID]_cover.jpg
└── ...
```
## 使用说明
### 安装依赖
```bash
cd dy-downloader
pip3 install -r requirements.txt
```
### 配置
1. 复制配置示例:
```bash
cp config.example.yml config.yml
```
2. 编辑配置文件，填入Cookie信息
### 运行
**使用配置文件**:
```bash
python3 run.py -c config.yml
```
**命令行参数**:
```bash
python3 run.py -u "https://www.douyin.com/user/xxxxx" -p ./downloads/
```
**查看帮助**:
```bash
python3 run.py --help
```
## 特性亮点

- 使用asyncio实现高性能并发
- 异步文件IO提升效率
- 异步数据库操作
### 2. 智能下载控制
- 速率限制避免封号
- 智能重试提高成功率
- 并发控制优化性能
### 3. 增量下载支持
- 数据库记录历史
- 自动跳过已下载内容
- 只下载新增作品
### 4. 美观的CLI界面
- Rich库渲染
- 实时进度显示
- 彩色输出
- 表格化统计
### 5. 灵活的配置系统
- YAML配置文件
- 命令行参数
- 环境变量
- 多层优先级
## 测试结果
### 测试环境
