# Feishu Rich Card — 飞书图文混排卡片
在飞书群聊中发送**图文并茂**的交互式卡片,用于汇报进展、展示分析结果、项目状态等。
## When to Use
- 汇报任务进展、项目状态
- 展示数据分析结果(图表 + 解读)
- 发送研究简报、阶段性成果
- 任何需要图文混排的飞书消息
## Architecture
```
生成图片(SVG→PNG / matplotlib / PIL)
↓
上传图片到飞书 → 获取 image_key
↓
构造 Card JSON (schema 2.0) → 嵌入 img 元素 + markdown 元素
↓
调用飞书 API 发送 interactive 消息
```
## Workflow
### Step 1: Prepare Images
图片来源可以是:
- **SVG UI 模板** → 用 `svg-ui-templates` skill 生成 SVG → cairosvg 转 PNG
- **matplotlib/seaborn** → 直接 savefig 为 PNG
- **PIL/Pillow** → 程序化生成图片
- **已有文件** → 直接使用本地 PNG/JPG
### Step 2: Upload & Send
使用 `references/send_card.py` 中的辅助函数:
```python
# 完整用法参见 references/send_card.py
from send_card import FeishuCardSender
sender = FeishuCardSender() # 自动读取 openclaw.json 凭证
# 发送图文卡片
sender.send_rich_card(
chat_id="oc_xxx",
title="📊 分析报告",
elements=[
{"type": "markdown", "content": "## 结果摘要\n\n发现 **3 个**显著差异基因"},
{"type": "image", "path": "/tmp/volcano_plot.png", "alt": "火山图"},
{"type": "markdown", "content": "> Gene X: FC=2.5, p<0.001"},
{"type": "hr"},
{"type": "image", "path": "/tmp/heatmap.png", "alt": "热图"},
{"type": "markdown", "content": "**结论:** 样本间差异显著,建议进一步验证。"},
],
header_template="blue" # blue/indigo/green/red/purple/violet/wathet/turquoise/yellow/grey
)
```
### Step 3: Quick One-liner (for simple cases)
```python
sender.send_image_report(
chat_id="oc_xxx",
title="🧬 单细胞分析完成",
intro="UMAP 降维完成,共识别 12 个细胞群:",
image_path="/tmp/umap.png",
conclusion="Cluster 5 为目标细胞群,marker: CD8A, GZMB, PRF1",
header_template="indigo"
)
```
## Card Elements Reference
| Element | Tag | 说明 |
|---------|-----|------|
| **Markdown** | `markdown` | 支持加粗、斜体、链接、列表、引用块、代码块 |
| **Image** | `img` | 需要 `image_key`(上传后获取) |
| **Divider** | `hr` | 水平分割线 |
| **Column Set** | `column_set` | 多列并排布局 |
| **Note** | `note` | 底部灰色备注 |
## Header Templates (颜色)
`blue` `wathet` `turquoise` `green` `yellow` `orange` `red` `carmine` `violet` `purple` `indigo` `grey`
## Key Rules
1. **图片必须先上传**到飞书获取 `image_key`,不能用 URL
2. **Card schema 必须是 `"2.0"`**
3. **每张卡片最多 50 个元素**
4. 图片建议宽度 600-1200px,飞书会自动缩放
5. markdown 中**不能嵌入图片**,图片必须是独立的 `img` 元素
6. 发送后 OpenClaw 的正常回复会重复,用 `NO_REPLY` 避免
## Integration with SVG UI Templates
当需要专业级可视化时,结合 `svg-ui-templates` skill:
```bash
# 1. 生成 SVG(用模板或自定义)
# 2. 转 PNG
python3 -c "import cairosvg; cairosvg.svg2png(url='report.svg', write_to='report.png', output_width=2400)"
# 3. 用本 skill 上传并发送卡片
```
## Default Chat ID
通过环境变量配置:`FEISHU_DEFAULT_CHAT_ID`(在 `.env` 中设置)
