# 医疗问诊 Agent FastAPI 后端
|
||
|
||
医疗问诊 Agent 是医疗教学平台中的问诊训练服务。后端负责 Django 用户身份校验、病例读取、多轮问诊、检查申请、诊断治疗提交、AI 评价、评分明细、PDF 报告和历史训练记录。
|
||
|
||
## 项目结构
|
||
|
||
仓库根目录可以直接部署为服务器的 `fastapi/` 目录：
|
||
|
||
```text
|
||
fastapi/
|
||
├── app/ # FastAPI 应用、Agent、服务、模型与提示词
|
||
├── scripts/ # 数据库迁移、结构检查与运维脚本
|
||
├── tests/ # 核心逻辑与接口测试
|
||
├── Dockerfile
|
||
├── requirements.txt
|
||
├── .env.example
|
||
└── .env.production.example
|
||
```
|
||
|
||
## 核心依赖
|
||
|
||
- Python 3.11
|
||
- FastAPI
|
||
- SQLAlchemy 2.x
|
||
- MySQL 8
|
||
- Redis 7
|
||
- OpenAI-compatible LLM API
|
||
- Django 用户中心 `/api/user/users/me/`
|
||
|
||
## 本地启动
|
||
|
||
```powershell
|
||
python -m venv .venv
|
||
.\.venv\Scripts\activate
|
||
pip install -r requirements.txt
|
||
copy .env.example .env
|
||
uvicorn app.main:app --host 127.0.0.1 --port 9000
|
||
```
|
||
|
||
本地 Swagger：
|
||
|
||
```text
|
||
http://127.0.0.1:9000/docs
|
||
```
|
||
|
||
真实密码、LLM Key 和 access token 只写入本地 `.env` 或服务器环境变量，不提交到 Git。
|
||
|
||
## Docker Compose 部署
|
||
|
||
服务器目录：
|
||
|
||
```text
|
||
/home/code/medical-ai/
|
||
├── django/
|
||
├── fastapi/ # 本仓库
|
||
├── vueapp/
|
||
├── vuecms/
|
||
└── docker-compose.yml
|
||
```
|
||
|
||
首次拉取：
|
||
|
||
```bash
|
||
cd /home/code/medical-ai
|
||
git clone http://82.157.235.104:3000/Liu_JB/LiuJinbao.git fastapi
|
||
cp fastapi/.env.production.example fastapi/.env
|
||
vi fastapi/.env
|
||
```
|
||
|
||
必须在服务器 `.env` 中填写：
|
||
|
||
- MySQL 密码和数据库名
|
||
- `LLM_API_KEY`
|
||
- 实际前端来源 `CORS_ALLOW_ORIGINS`
|
||
- Nginx 使用 `/fastapi/` 前缀时保留 `APP_ROOT_PATH=/fastapi`
|
||
|
||
父目录 `docker-compose.yml` 的 FastAPI 服务需要包含：
|
||
|
||
```yaml
|
||
fastapi:
|
||
build:
|
||
context: ./fastapi
|
||
container_name: fastapi
|
||
restart: always
|
||
ports:
|
||
- "9000:9000"
|
||
env_file:
|
||
- ./fastapi/.env
|
||
volumes:
|
||
- ./logs/fastapi:/app/logs
|
||
- ./data/fastapi-reports:/app/storage/reports
|
||
depends_on:
|
||
- mysql
|
||
- redis
|
||
- django
|
||
networks:
|
||
- medical
|
||
```
|
||
|
||
构建并启动：
|
||
|
||
```bash
|
||
cd /home/code/medical-ai
|
||
docker compose config
|
||
docker compose build fastapi
|
||
docker compose up -d fastapi
|
||
docker compose logs --tail=200 fastapi
|
||
```
|
||
|
||
后续更新：
|
||
|
||
```bash
|
||
cd /home/code/medical-ai/fastapi
|
||
git pull origin main
|
||
cd ..
|
||
docker compose build fastapi
|
||
docker compose up -d fastapi
|
||
```
|
||
|
||
## 数据库初始化与检查
|
||
|
||
服务启动后先进行只读结构检查：
|
||
|
||
```bash
|
||
cd /home/code/medical-ai
|
||
docker compose exec fastapi python scripts/check_final_schema.py
|
||
docker compose exec fastapi python scripts/check_final_demo_readiness.py
|
||
```
|
||
|
||
仅在结构检查确认缺少 Agent 所需表时，备份数据库后执行：
|
||
|
||
```bash
|
||
docker compose exec fastapi python scripts/migrate_to_new_schema.py
|
||
docker compose exec fastapi python scripts/migrate_user_department_score_detail.py
|
||
```
|
||
|
||
迁移脚本使用 `create_all` 补齐 Agent 所需表，不删除 Django 或现有业务表；`migrate_to_new_schema.py` 会在缺少对应数据时写入 Demo 病例和基础数据。
|
||
|
||
## 部署验证
|
||
|
||
容器内部端口验证：
|
||
|
||
```bash
|
||
curl http://127.0.0.1:9000/health/live
|
||
curl http://127.0.0.1:9000/health/ready
|
||
```
|
||
|
||
使用 Nginx `/fastapi/` 代理后的公网验证：
|
||
|
||
```text
|
||
http://8.160.178.88/fastapi/docs
|
||
http://8.160.178.88/fastapi/openapi.json
|
||
http://8.160.178.88/fastapi/health/ready
|
||
```
|
||
|
||
`/health/live` 返回 200 表示 FastAPI 进程正常。`/health/ready` 返回 200 表示 MySQL、Redis 和关键配置已经就绪；返回 503 时查看响应中的检查项和容器日志。
|
||
|
||
验证 Django 用户中心联调：
|
||
|
||
```bash
|
||
curl "http://8.160.178.88/fastapi/api/v1/auth/me" \
|
||
-H "Authorization: Bearer <access_token>" \
|
||
-H "X-Entry-Scene: production_vue"
|
||
```
|
||
|
||
## 测试
|
||
|
||
```powershell
|
||
python -m compileall app scripts tests
|
||
python tests\test_core_logic.py
|
||
python tests\test_api_contract.py
|
||
python tests\test_demo_flow.py
|
||
python tests\test_import_source_case_sql.py
|
||
```
