## 使用示例

### JavaScript (Fetch)

```javascript
// 导航到百度
await fetch('http://localhost:18766/browser/navigate', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ url: 'https://www.baidu.com' })
});

// 获取系统信息
const response = await fetch('http://localhost:18766/system/info');
const data = await response.json();
console.log(`CPU 使用率: ${data.data.cpu.usage}%`);

// 截图并 OCR
const screenshotRes = await fetch('http://localhost:18766/vision/screenshot');
const screenshotData = await screenshotRes.json();

const ocrRes = await fetch('http://localhost:18766/vision/ocr', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ imageBase64: screenshotData.screenshot })
});
const ocrData = await ocrRes.json();
console.log('屏幕文字:', ocrData.text);
```

### Python (Requests)

```python
import requests

# 打开浏览器并导航
requests.post('http://localhost:18766/browser/navigate', 
              json={'url': 'https://www.baidu.com'})

# 输入搜索词
requests.post('http://localhost:18766/browser/type',
              json={'selector': '#kw', 'text': '小白龙 AI'})

# 点击搜索按钮
requests.post('http://localhost:18766/browser/click',
              json={'selector': '#su'})

# 获取系统信息
response = requests.get('http://localhost:18766/system/info')
data = response.json()
print(f"内存使用: {data['data']['memory']['percentage']}%")
```

### cURL

```bash
# 导航到 URL
curl -X POST http://localhost:18766/browser/navigate \
  -H "Content-Type: application/json" \
  -d '{"url": "https://www.baidu.com"}'

# 获取系统信息
curl http://localhost:18766/system/info

# 执行 PowerShell
curl -X POST http://localhost:18766/powershell/exec \
  -H "Content-Type: application/json" \
  -d '{"script": "Get-Date"}'
```

## 前端集成

小白龙前端已内置 `JarvisBridge` 类，可直接使用：

```javascript
// 在 app.js 中使用
const jarvis = new JarvisBridge();

// 浏览器控制
await jarvis.browserNavigate('https://www.baidu.com');
await jarvis.browserType('#kw', '小白龙 AI');
await jarvis.browserClick('#su');

// 系统监控
const sysInfo = await jarvis.getSystemInfo();
console.log(`CPU: ${sysInfo.cpu.usage}%`);

// 截图 OCR
const screenshot = await jarvis.captureScreenshot();
const text = await jarvis.recognizeText(screenshot);

// 执行 PowerShell
const result = await jarvis.executePowerShell('Get-Process');

// 打开应用
await jarvis.openApplication('notepad');
```
