# Publisher Module

Multi-platform content publishing for Sage. Covers 10 platforms: weibo, douyin, bilibili, kuaishou, wechat (公众号), channels (视频号), xiaohongshu, toutiao, youtube, twitter.

## Architecture

- **Repo**: `git@git.opencomputing.cn:yumoqing/publisher.git`
- **Tables** (4): `publisher_platform`, `publisher_content`, `publisher_task`, `publisher_log`
- **Content types**: article, video, audio, image
- **DSPY pattern**: `import json` + `get_sor_context(env, 'sage')` + `env.run_scheduled(sor)`

## Adding a Platform

Edit `publisher/platforms.py`:

```python
from publisher.platforms import register

def publish_newplat(platform, content):
    headers = {'Authorization': 'Bearer ' + platform['access_token']}
    body = {'text': content.get('title', '')}
    return ('POST', 'https://api.newplat.com/publish', headers, body, content['content_type'])

register('newplat', '新平台', publish_newplat, ['article', 'image', 'video'])
```

Each platform needs in `publisher_platform`:
- `app_key` + `app_secret` (all)
- `access_token` (all)
- `refresh_token` (YouTube)
- `extra_config` JSON with platform-specific fields (uid/open_id/channel_id/etc.)

## Platform Credentials Quick Reference

| platform_code | extra_config fields | Notes |
|---|---|---|
| weibo | uid | Weibo user UID required |
| douyin | open_id | OAuth authorized user |
| bilibili | cookie | Some endpoints need Cookie |
| kuaishou | open_id | User identifier |
| wechat | — | Token expires every 2h |
| channels | open_id | Separate auth from 公众号 |
| xiaohongshu | user_id | Creator ID |
| toutiao | user_id | Author ID |
| youtube | channel_id | Needs refresh_token |
| twitter | oauth_token_secret | OAuth 1.0a |

## Deployment Checklist

1. `cp -r publisher $SAGE_ROOT/`
2. `cp models/publisher_*.json $SAGE_ROOT/models/`
3. `cp -r wwwroot/publisher $SAGE_ROOT/wwwroot/`
4. Execute `ddl/mysql.sql`
5. Run `scripts/load_path.py`
6. `from publisher.init import load_publisher` + `load_publisher()` in sage.py
7. Restart Sage

## Pitfalls

- Platform APIs require real credentials — access_token expires, need refresh flow
- Content format differs per platform (Weibo 2000, WeChat title 64, Twitter 280)
- Network errors auto-retry 3 times before marking failed
- `sor` parameter allows DSPY context reuse
