## 📋 Procedure
|
||
|
||
### Step 1: 通过SSH获取实时服务器数据
|
||
|
||
调用 `ssh_exec` 采集以下数据：
|
||
|
||
```bash
|
||
# 主机名
|
||
hostname
|
||
# CPU核心数
|
||
nproc
|
||
# 系统负载
|
||
uptime | awk -F'load average:' '{print $2}'
|
||
# 运行时间（短格式）
|
||
uptime -p | sed 's/up //'
|
||
# 运行时间（天）
|
||
cat /proc/uptime | awk '{printf "%d", $1/86400}'
|
||
# 内存
|
||
free -h | awk 'NR==2{print $2" "$3" "$4}'
|
||
# Swap
|
||
free -h | awk 'NR==3{printf $2" "$3}'
|
||
# 磁盘（系统盘）
|
||
df -h / | tail -1 | awk '{print $2" "$3" "$4" "$5}'
|
||
# 磁盘（数据盘/www）
|
||
df -h /www 2>/dev/null | tail -1 | awk '{print $2" "$3" "$4" "$5}' || echo "无"
|
||
# T2I服务状态
|
||
curl -s -o /dev/null -w "%{http_code}" http://localhost:8999/text2img/generate -X POST -d '{}'
|
||
# NapCat状态
|
||
docker ps --filter "name=napcat" --format "{{.Status}}"
|
||
# Docker容器数量
|
||
docker ps -q | wc -l
|
||
# 监听端口数
|
||
ss -tlnp | grep -c "LISTEN"
|
||
```
|
||
|
||
### Step 2: 填充HTML模板
|
||
|
||
将采集到的数据填入以下HTML模板：
|
||
|
||
```html
|
||
<!DOCTYPE html>
|
||
<html>
|
||
<head>
|
||
<meta charset="utf-8">
|
||

|
||
|
||
### Step 3: 通过T2I渲染为图片
|
||
|
||
```python
|
||
import urllib.request, json
|
||
|
||
# 将填充好数据的HTML通过T2I渲染
|
||
# 注意：viewport_width=1200会因模板scale(2.0)被截断，必须用1920+ultra
|
||
html_content = "填充数据后的HTML"
|
||
data = json.dumps({
|
||
"html": html_content, "json": True,
|
||
"options": {
|
||
"type": "png",
|
||
"full_page": True,
|
||
"viewport_width": 1920,
|
||
"device_scale_factor_level": "ultra"
|
||
}
|
||
}).encode()
|
||
|
||
req = urllib.request.Request(
|
||
"http://172.17.0.1:8999/text2img/generate",
|
||
data=data, headers={"Content-Type":"application/json"}
|
||
)
|
||
with urllib.request.urlopen(req, timeout=30) as resp:
|
||
r = json.loads(resp.read())
|
||
img_name = r["data"]["id"].replace("data/", "")
|
||
|
||
# 下载图片到容器本地
|
||
with urllib.request.urlopen(
|
||
f"http://172.17.0.1:8999/text2img/data/{img_name}", timeout=30
|
||
) as resp:
|
||
img_data = resp.read()
|
||
|
||
local_path = f"/AstrBot/data/temp/server_report_{timestamp}.png"
|
||
with open(local_path, 'wb') as f:
|
||
f.write(img_data)
|
||
```
|
||
|
||
### Step 4: 发送图片到QQ
|
||
|
||
```python
|
||
send_message_to_user(messages=[{
|
||
"type": "image",
|
||
"path": local_path
|
||
}])
|
||
```
|
||
|
||
### Step 5: 备用方案（QQ离线时发邮件）
|
||
|
||
如果QQ不可用，调用 `smtp_send_html_email` 将报告作为HTML邮件发送到主人邮箱。
