# Multi-Agent Software Delivery System
|
||||
|
||||
基于 CrewAI + Qwen3.5-flash 的多智能体软件交付系统,支持 SSE 实时推送。
|
||||
|
||||
## 📋 功能特性
|
||||
|
||||
- **多智能体协作**: 4 个专业 Agent 协同完成软件交付
|
||||
- ProductManager: 产品需求分析
|
||||
- QAEngineer: 测试计划制定
|
||||
- SoftwareDeveloper: 技术方案设计
|
||||
- Coordinator: 质量审核与交付
|
||||
|
||||
- **实时通信**: 基于 SSE 协议实时推送执行日志
|
||||
- **异步处理**: 任务异步启动,不阻塞 API 响应
|
||||
- **并发支持**: 多用户同时请求互不干扰
|
||||
|
||||
## 🔑 关键技术点
|
||||
|
||||
### 1. SSE 数据格式设计
|
||||
|
||||
统一的 JSON 格式,便于前端解析:
|
||||
|
||||
```json
|
||||
{
|
||||
"task_id": "550e8400-e29b...",
|
||||
"sequence": 1,
|
||||
"agent_name": "ProductManager",
|
||||
"event_type": "thought",
|
||||
"content": "正在分析用户需求,提取关键指标...",
|
||||
"timestamp": "2023-10-27T10:00:00Z"
|
||||
}
|
||||
```
|
||||
|
||||
**字段说明**:
|
||||
- `task_id`: 任务唯一标识,用于区分不同用户的请求
|
||||
- `sequence`: 序列号(每个 task_id 独立递增),用于检测消息丢失
|
||||
- `agent_name`: 发送事件的 Agent 名称
|
||||
- `event_type`: 事件类型(start/thought/action/output/end/error)
|
||||
- `content`: 事件内容
|
||||
- `timestamp`: UTC 时间戳(ISO 8601 格式)
|
||||
|
||||
### 2. 并发处理逻辑
|
||||
|
||||
**核心挑战**:CrewAI 默认是同步运行的,而 FastAPI 和 SSE 需要异步。
|
||||
|
||||
**解决方案**:
|
||||
|
||||
```python
|
||||
# 在 TaskStreamQueue 中实现线程安全的消息发布
|
||||
def put_nowait(self, event: StreamEvent) -> bool:
|
||||
"""
|
||||
从同步线程(如 CrewAI 事件处理器)安全地发布事件
|
||||
|
||||
使用 run_coroutine_threadsafe 将协程提交到事件循环执行
|
||||
这是实现 CrewAI(同步)与 SSE(异步)集成的关键
|
||||
"""
|
||||
future = asyncio.run_coroutine_threadsafe(
|
||||
self.queue.put(event),
|
||||
self._loop
|
||||
)
|
||||
future.result(timeout=5.0)
|
||||
return True
|
||||
```
|
||||
|
||||
**关键实现**:
|
||||
1. 使用 `asyncio.Queue` 实现异步非阻塞消息队列
|
||||
2. 通过 `asyncio.Lock` 保证并发安全
|
||||
3. 每个 `task_id` 独立队列,实现任务隔离
|
||||
4. 使用 `run_coroutine_threadsafe` 从同步线程安全发布事件
|
||||
5. 确保 `stream_manager` 能安全地在线程间传递消息
|
||||
|
||||
### 3. 多任务隔离机制
|
||||
|
||||
```python
|
||||
class StreamManager:
|
||||
"""全局流管理器 - 管理所有任务的 SSE 流"""
|
||||
|
||||
def __init__(self):
|
||||
# task_id -> TaskStreamQueue 映射
|
||||
self.streams: Dict[str, TaskStreamQueue] = {}
|
||||
self._lock = asyncio.Lock() # 并发控制
|
||||
```
|
||||
|
||||
- 每个 `task_id` 对应独立的 `TaskStreamQueue`
|
||||
- 使用 `asyncio.Lock` 保护字典操作
|
||||
- 定期清理已完成的流(默认每小时)
|
||||
- 序列号计数器按 `task_id` 独立维护
|
||||
|
||||
## 🚀 快速开始
|
||||
|
||||
### 1. 安装依赖
|
||||
|
||||
```bash
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
### 2. 测试模块
|
||||
|
||||
运行测试脚本验证所有模块正常:
|
||||
|
||||
```bash
|
||||
python test_import.py
|
||||
```
|
||||
|
||||
预期输出:
|
||||
```
|
||||
[OK] Module Imports
|
||||
[OK] Agent Creation
|
||||
[OK] Stream Manager
|
||||
[OK] API Endpoints
|
||||
|
||||
[SUCCESS] All tests passed! System is ready.
|
||||
```
|
||||
|
||||
### 3. 配置环境变量
|
||||
|
||||
复制 `.env.example` 为 `.env` 并填入 DashScope API Key:
|
||||
|
||||
```bash
|
||||
cp .env.example .env
|
||||
```
|
||||
|
||||
编辑 `.env` 文件:
|
||||
```
|
||||
DASHSCOPE_API_KEY=sk-your-actual-api-key
|
||||
```
|
||||
|
||||
获取 API Key: https://dashscope.console.aliyun.com/
|
||||
|
||||
### 4. 启动服务
|
||||
|
||||
```bash
|
||||
python main.py
|
||||
```
|
||||
|
||||
或使用 uvicorn:
|
||||
```bash
|
||||
uvicorn main:app --host 0.0.0.0 --port 8000 --reload
|
||||
```
|
||||
|
||||
### 4. 访问服务

```
|
||||
|
||||
## ⚙️ 配置说明
|
||||
|
||||
### LLM 配置
|
||||
|
||||
在 `agents_config.py` 中配置:
|
||||
|
||||
```python
|
||||
QWEN_MODEL_CONFIG = {
|
||||
"model": "qwen-plus", # Qwen3.5-flash
|
||||
"base_url": "https://dashscope.aliyuncs.com/compatible-mode/v1",
|
||||
"api_key_env": "DASHSCOPE_API_KEY",
|
||||
}
|
||||
```
|
||||
|
||||
### Agent 角色定制
|
||||
|
||||
在 `agents_config.py` 中修改各 Agent 的:
|
||||
- `role`: 角色名称
|
||||
- `goal`: 目标
|
||||
- `backstory`: 背景描述
|
||||
- `TASK_TEMPLATES`: 任务 Prompt 模板
|
||||
|
||||
## 🔧 高级用法
|
||||
|
||||
### 自定义事件处理器
|
||||
|
||||
继承 `CrewEventsHandler` 类并重写回调方法:
|
||||
|
||||
```python
|
||||
class MyCustomHandler(CrewEventsHandler):
|
||||
def on_agent_output(self, agent, output):
|
||||
# 自定义处理逻辑
|
||||
pass
|
||||
```
|
||||
|
||||
### 调整并发策略
|
||||
|
||||
在 `stream_manager.py` 中调整队列大小和清理策略:
|
||||
|
||||
```python
|
||||
TaskStreamQueue(task_id, max_size=1000) # 默认 1000
|
||||
```
|
||||
|
||||
## 🐛 故障排查
|
||||
|
||||
### 问题:SSE 连接立即断开
|
||||
|
||||
**解决**: 确保 Nginx 配置中禁用了缓冲:
|
||||
```nginx
|
||||
proxy_buffering off;
|
||||
proxy_cache off;
|
||||
proxy_request_buffering off;
|
||||
```
|
||||
|
||||
### 问题:LLM 调用失败
|
||||
|
||||
**检查**:
|
||||
1. DASHSCOPE_API_KEY 是否正确配置
|
||||
2. 网络连接是否正常
|
||||
3. API Key 是否有足够额度
|
||||
|
||||
### 问题:内存占用过高
|
||||
|
||||
**解决**: 调整 `cleanup_old_streams` 的调用频率和保留时间
|
||||
|
||||
## 🏗️ Docker 部署
|
||||
|
||||
### 使用 Docker Compose(推荐)
|
||||
|
||||
```bash
|
||||
# 1. 设置环境变量
|
||||
export DASHSCOPE_API_KEY=sk-your-api-key
|
||||
|
||||
# 2. 启动服务
|
||||
docker-compose up -d
|
||||
|
||||
# 3. 查看日志
|
||||
docker-compose logs -f multi-agent-system
|
||||
|
||||
# 4. 停止服务
|
||||
docker-compose down
|
||||
```
|
||||
|
||||
### 生产环境部署(带 Nginx)
|
||||
|
||||
```bash
|
||||
# 使用 production profile 启动(包含 Nginx)
|
||||
docker-compose --profile production up -d
|
||||
```
|
||||
|
||||
**目录结构**:
|
||||
```
|
||||
.
|
||||
├── docker-compose.yml # Docker Compose 配置
|
||||
├── Dockerfile # 应用镜像构建文件
|
||||
├── nginx.conf # Nginx 配置(反向代理 + SSE 支持)
|
||||
├── .env # 环境变量文件
|
||||
└── ...
|
||||
```
|
||||
|
||||
### Nginx 关键配置
|
||||
|
||||
对于 SSE 流端点,Nginx 必须禁用缓冲:
|
||||
|
||||
```nginx
|
||||
location /api/stream/ {
|
||||
proxy_pass http://multi-agent-system:8000;
|
||||
|
||||
# HTTP/1.1 支持(SSE 必需)
|
||||
proxy_http_version 1.1;
|
||||
proxy_set_header Connection "";
|
||||
|
||||
# 禁用缓冲(关键)
|
||||
proxy_buffering off;
|
||||
proxy_cache off;
|
||||
proxy_request_buffering off;
|
||||
|
||||
# 长连接超时
|
||||
proxy_read_timeout 300s;
|
||||
}
|
||||
```
|
||||
|
||||
## 📝 注意事项
|
||||
|
||||
1. **生产环境部署**:
|
||||
- 限制 CORS 允许的来源域名
|
||||
- 添加 API 认证机制
|
||||
- 使用 Redis 等持久化队列替代内存队列
|
||||
|
||||
2. **性能优化**:
|
||||
- 调整 SSE 队列大小避免内存溢出
|
||||
- 限制单个任务的超时时间
|
||||
- 实现任务优先级队列
|
||||
|
||||
3. **安全考虑**:
|
||||
- 验证用户输入防止注入攻击
|
||||
- 限制请求频率防止滥用
|
||||
- 记录审计日志

## 🚀 快速开始
|
||||
|
||||
### 1. 配置 API Key
|
||||
|
||||
编辑 `.env` 文件,设置您的阿里百炼 API Key:
|
||||
|
||||
```bash
|
||||
DASHSCOPE_API_KEY=sk-your-actual-api-key-here
|
||||
```
|
||||
|
||||
获取 API Key: https://dashscope.console.aliyun.com/
|
||||
|
||||
### 2. 安装依赖
|
||||
|
||||
```bash
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
### 3. 启动服务
|
||||
|
||||
**方式一:直接运行 Python**
|
||||
```bash
|
||||
python main.py
|
||||
```
|
||||
|
||||
**方式二:使用 uvicorn**
|
||||
```bash
|
||||
uvicorn main:app --host 0.0.0.0 --port 8000 --reload
|
||||
```
|
||||

|
||||
|
||||
## 📝 使用方法
|
||||
|
||||
### 方法一:通过 Web UI(推荐)
|
||||
|
||||
1. 访问 http://localhost:8000/test-ui
|
||||
2. 在输入框中输入您的需求,例如:
|
||||
```
|
||||
开发一个简单的在线待办事项应用(Todo App),包含以下功能:
|
||||
1. 用户可以注册和登录
|
||||
2. 创建、编辑、删除待办事项
|
||||
3. 标记事项为完成/未完成
|
||||
4. 按优先级和截止日期排序
|
||||
5. 基本的搜索和过滤功能
|
||||
|
||||
技术栈要求:
|
||||
- 后端:Python FastAPI
|
||||
- 数据库:SQLite
|
||||
- 前端:简单的 HTML/CSS/JavaScript
|
||||
```
|
||||
3. 点击"启动任务"按钮
|
||||
4. 实时查看各 Agent 的执行过程
|
||||
5. 完成后查看生成的文档
|
||||
|
||||
### 方法二:通过 API 调用
|
||||
|
||||
使用 curl 或任何 HTTP 客户端:
|
||||
|
||||
```bash
|
||||
# 启动任务
|
||||
curl -X POST http://localhost:8000/api/run_task \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"user_requirement": "开发一个博客系统",
|
||||
"skip_confirmation": true
|
||||
}'
|
||||
|
||||
# 返回示例:
|
||||
# {"task_id":"uuid","status":"started","message":"..."}
|
||||
```
|
||||
|
||||
然后订阅 SSE 流:
|
||||
|
||||
```bash
|
||||
curl -N http://localhost:8000/api/stream/{task_id}
|
||||
```
|
||||
|
||||
### 方法三:使用示例脚本
|
||||
|
||||
运行提供的示例脚本:
|
||||
|
||||
```bash
|
||||
python example_usage.py
|
||||
```
|
||||
|
||||
这会自动保存生成的内容到 `generated_output/` 目录。
|
||||
|
||||

生成的文件保存在 `generated_output/task_YYYYMMDD_HHMMSS/` 目录下。
|
||||
|
||||
**Windows 用户**:
|
||||
```powershell
|
||||
# 打开最新生成的目录
|
||||
explorer (Get-ChildItem generated_output -Directory | Sort-Object LastWriteTime -Descending | Select-Object -First 1).FullName
|
||||
```
|
||||
|
||||
**Linux/Mac 用户**:
|
||||
```bash
|
||||
# 打开最新生成的目录
|
||||
xdg-open $(ls -td generated_output/task_* | head -n1) # Linux
|
||||
open $(ls -td generated_output/task_* | head -n1) # Mac
|
||||
```
|
||||
|
||||
或者直接在文件管理器中浏览 `generated_output/` 目录。
|
||||
|
||||
## 💡 实用技巧
|
||||
|
||||
### 1. 实时监控任务进度
|
||||
|
||||
在另一个终端窗口查看日志:
|
||||
|
||||
```bash
|
||||
# Docker Compose 方式
|
||||
docker-compose logs -f multi-agent-system
|
||||
|
||||
# 直接运行
|
||||
# 日志会自动输出到控制台
|
||||
```
|
||||
|
||||
### 2. 自定义输出目录
|
||||
|
||||
修改 `example_usage.py` 中的 `output_dir` 参数:
|
||||
|
||||
```python
|
||||
await save_generated_content(task_id, output_dir="my_custom_output")
|
||||
```
|
||||
|
||||
### 3. 批量处理多个需求
|
||||
|
||||
创建批处理脚本:
|
||||
|
||||
```python
|
||||
requirements = [
|
||||
"需求 1...",
|
||||
"需求 2...",
|
||||
"需求 3..."
|
||||
]
|
||||
|
||||
for req in requirements:
|
||||
task_id = await run_multi_agent_task(user_requirement=req)
|
||||
await save_generated_content(task_id)
|
||||
```
|
||||
|
||||
## ⚠️ 常见问题
|
||||
|
||||
### Q: 为什么没有生成文件?
|
||||
|
||||
**A**: 确保:
|
||||
1. API Key 已正确配置
|
||||
2. 网络连接正常
|
||||
3. 任务执行完成(看到"任务执行完成"事件)
|
||||
|
||||
### Q: 生成的内容在哪里?
|
||||
|
||||
**A**:
|
||||
- 默认在 `generated_output/task_时间戳/` 目录
|
||||
- 可以通过 Web UI 直接查看
|
||||
- 或在控制台查找保存路径
|
||||
|
||||
### Q: 如何重新查看生成的内容?
|
||||
|
||||
**A**:
|
||||
1. 找到对应的任务时间戳目录
|
||||
2. 打开相应的 .md 文件
|
||||
3. 使用 Markdown 阅读器或 VS Code 查看
|
||||
|
||||
### Q: 可以修改生成的文档吗?
|
||||
|
||||
**A**: 当然可以!生成的文档是 Markdown 格式,可以使用任何文本编辑器修改。
|
||||
|
||||
## 🎯 最佳实践
|
||||
|
||||
1. **明确需求描述**:需求越详细,生成的文档越准确
|
||||
2. **指定技术栈**:明确说明使用的技术和框架
|
||||
3. **设定约束条件**:如性能要求、安全要求等
|
||||
4. **迭代优化**:根据生成结果调整需求描述
|
||||

2. **版本管理**: 建议将生成的文档纳入 Git 版本控制
|
||||
3. **敏感信息**: 注意不要泄露 API Key 等敏感信息
|
||||
4. **磁盘空间**: 长期运行会产生大量文件,定期清理旧文件
|
||||
|
||||
## 🎯 使用建议
|
||||
|
||||
1. **审查生成内容**: AI 生成的内容可能有误,务必人工审查
|
||||
2. **迭代优化**: 根据实际反馈调整需求描述,重新生成
|
||||
3. **团队协作**: 将生成的文档作为讨论基础,团队共同完善
|
||||
4. **知识沉淀**: 将优秀实践固化到需求模板中
|
||||
