```
## 安装
### 1. 复制文件到 Sage 部署目录
```bash
SAGE_ROOT=/path/to/sage
cp -r hotspot $SAGE_ROOT/ # Python 包
cp json/hotspot_*.json $SAGE_ROOT/json/
cp -r wwwroot/hotspot $SAGE_ROOT/wwwroot/
git clone git@git.opencomputing.cn:yumoqing/hotspot.git /tmp/hotspot
# Python 包
cp -r /tmp/hotspot/hotspot $SAGE_ROOT/
# 表定义
cp /tmp/hotspot/json/hotspot_*.json $SAGE_ROOT/json/
# Web UI + 端点
cp -r /tmp/hotspot/wwwroot/hotspot $SAGE_ROOT/wwwroot/
```
建表、注册权限、加菜单 → 见 README 原文。
### 2. 建表
```bash
mysql -u <user> -p sage < /tmp/hotspot/ddl/mysql.sql
```
### 3. 注册权限
打开 `$SAGE_ROOT/load_path.py`,找到末尾的 `"""` 结束符,在它**前面**插入 `install/load_path_append.txt` 的内容。
```bash
cd /tmp/hotspot
# 找到 SAGE_ROOT/load_path.py 中最后一个 """ 的前一行
# 把 install/load_path_append.txt 的内容粘贴进去
# 然后:
cd $SAGE_ROOT && python load_path.py
```
### 4. 添加菜单
打开 `$SAGE_ROOT/wwwroot/menu.ui`,在 `items` 数组末尾追加 `install/menu_append.json` 的内容(注意前面加逗号)。
### 5. 重启 Sage
访问 `/hotspot`
## 使用流程
1. **添加来源** → 进入「来源管理」标签页,点击新增
- 类型选 `api` 配合 `parser=builtin` 使用内置解析器
- 或选 `rss`/`api` 配合 `parser=json_path` 自定义提取规则
2. **配置提取规则** → 在 `parser_config` 字段填入 JSON
```json
{"parser": "builtin", "builtin_name": "weibo_hot"}
```
或自定义:
```json
{
"parser": "json_path",
"item_path": "$.data.list[*]",
"field_map": {
"title": "word",
"url": "link",
"heat_score": "hotValue"
}
}
```
3. **配置调度** → 在「调度配置」标签页添加 cron 或间隔
4. **执行抓取** → 仪表盘点击「立即抓取全部来源」
5. **查看日志** → 「抓取日志」标签页检查成功率/错误详情
6. **执行分析** → 点击「执行分析」计算五维评分和状态
7. **浏览热点** → 「热点条目」标签页按状态筛选
8. **设置预警** → 「预警规则」标签页配置自动通知
## 内置解析器
| 解析器名 | 平台 | API 端点 | 备注 |
|---------|------|---------|------|
| `weibo_hot` | 微博热搜 | weibo.com/ajax/side/hotSearch | 需 UA 头 |
| `zhihu_hot` | 知乎热榜 | zhihu.com/api/v3/feed/topstory/hot-lists | — |
| `baidu_hot` | 百度热搜 | top.baidu.com/board | — |
| `toutiao_hot` | 头条热榜 | toutiao.com/hot-event/hot-board | 需 Referer |
| `bilibili_hot` | B站热门 | api.bilibili.com/x/web-interface/popular | — |
| `douyin_hot` | 抖音热点 | 第三方聚合接口 | 非官方,可能不稳定 |
| `36kr_hot` | 36氪热榜 | 36kr.com/api/search/list/info-flow/hot | — |
| `github_trending` | GitHub | api.github.com/search/repositories | — |
| `hackernews` | HackerNews | firebaseio.com (两步抓取) | — |
| `v2ex_hot` | V2EX | v2ex.com/api/topics/hot.json | — |
| `rsshub` | RSSHub | 来源 url 即 RSSHub 地址 | 解析 RSS/Atom |
## 提取器类型
| parser 值 | 适用场景 | 配置要点 |
|-----------|---------|---------|
| `builtin` | 使用内置解析器 | 设置 `builtin_name` |
| `json_path` | REST API 返回 JSON | `item_path` + `field_map` |
| `css` | HTML 页面 (轻量) | `item_selector` + `field_map` — 仅支持 `<a>` 标签提取,完整 CSS 需引入 BeautifulSoup |
| `regex` | 非结构化文本 | `item_regex` (命名捕获组) + `field_map` |
| `rss` | RSS/Atom feed | 自动解析,无需额外配置 |
## 状态分类逻辑
```
热度衰减: adjusted_heat = raw_heat × e^(-hours_alive / 168)
状态判定:
hours_alive > 336 (14天) → expired
336 > hours_alive > 168 → cooling
adjusted_heat > 5000 → hot
adjusted_heat > 500 → rising (velocity > 50) / emerging
adjusted_heat > 100 → rising (velocity > 100) / emerging
其他 → emerging
```
## 依赖
- **Sage** >= 0.0.1
- **aiohttp** (Python, 用于异步 HTTP 请求)
- **MySQL** / MariaDB
## 已知限制
- CSS 提取器为轻量正则实现,复杂页面结构建议使用 `json_path``builtin`
- 抖音解析器使用第三方聚合接口,官方 API 需企业资质
- 无 Headless Browser 集成(需单独部署 Playwright/Selenium

# Hotspot Radar Module
When the user works with or asks about the Hotspot Radar platform (热点雷达), load this skill.
## Architecture
- **Repo**: `/Users/ymq/devops/hotspot``git@git.opencomputing.cn:yumoqing/hotspot.git`
- **Python package**: `hotspot/` with 4 modules:
- `parsers.py` — 11 builtin platform parsers + 4 extractors (json_path/css/regex/rss)
- `engine.py``run_fetch()` orchestrates source→fetch→extract→save→log
- `analysis.py``run_analysis()` 5-dimension scoring + 7-day half-life classifier
- `db.py``save_items()`, `write_fetch_log()`, `get_stats()`
- **Sage integration**: `.dspy` files are 1-line wrappers calling the Python package
- **Tables** (6): `hotspot_source`, `hotspot_schedule`, `hotspot_fetch_log`, `hotspot_item`, `hotspot_analysis`, `hotspot_alert`
- **DB name**: `sage` (matches Sage const.py)
## Adding a New Builtin Parser
Edit `hotspot/parsers.py`, add at module bottom:
```python
from hotspot.parsers import _reg
_reg('new_platform',
'https://api.example.com/hot',
lambda data: [
{'title': item['name'], 'url': item['link'], 'heat_score': item['score']}
for item in data.get('list', [])
],
{'User-Agent': 'Mozilla/5.0'})
```
Then in Sage, add a source with:
```json
{"parser": "builtin", "builtin_name": "new_platform"}
```
## Adding a Custom Extractor Rule
In Sage → 来源管理 → 编辑 → parser_config:
```json
{
"parser": "json_path",
"item_path": "$.result.items[*]",
"field_map": {
"title": "name",
"url": "href",
"heat_score": "popularity",
"summary": "description",
"category": "type"
}
}
```
## Deployment Checklist
1. `cp -r hotspot $SAGE_ROOT/`
2. `cp json/hotspot_*.json $SAGE_ROOT/json/`
3. `cp -r wwwroot/hotspot $SAGE_ROOT/wwwroot/`
4. Execute `ddl/mysql.sql` against Sage database
5. Append `install/load_path_append.txt` into `load_path.py` before closing `"""`
6. Append `install/menu_append.json` into `menu.ui` items array
7. `cd $SAGE_ROOT && python load_path.py`
8. Restart Sage
## Pitfalls
- **Sage import path**: The `hotspot/` Python package must be at `$SAGE_ROOT/hotspot/` so `from hotspot.engine import run_fetch` works in DSPY files.
- **DB name**: Always `sage` — never change the dbname in JSON table defs.
- **parser_config JSON**: Must be valid JSON. Malformed config → no items extracted → log shows `items_total: 0`.
- **aiohttp timeout**: All HTTP calls use 30s timeout. Slow sources will be logged as failed.
- **CSS extractor limitation**: Only extracts `<a href="...">text</a>` patterns. Full CSS needs BeautifulSoup4 (not included — Sage doesn't bundle it).
## Verification
```bash
cd /Users/ymq/devops/hotspot
python3 -c "
import ast, json
for f in ['hotspot/__init__.py','hotspot/parsers.py','hotspot/engine.py','hotspot/analysis.py','hotspot/db.py']:
ast.parse(open(f).read()); print(f'OK {f}')
for t in ['hotspot_source','hotspot_schedule','hotspot_fetch_log','hotspot_item','hotspot_analysis','hotspot_alert']:
json.load(open(f'json/{t}.json')); print(f'OK {t}')
print('All OK')
"
```
