🌅 導言:當代理人有「雙手」
在 2026 年,AI Agent 的能力已經從「聽覺+觸覺」升級為「全方位感知+操作」。當你的代理人不再只是處理數據,而是能夠點擊、輸入、滾動、截圖、填表時——這場革命才真正開始。
OpenClaw 的 Browser Automation 功能,就是賦予代理人的「雙手」。無論你是想讓代理人自動填寫表單、點擊按鈕、滾動頁面、截取螢幕快照,還是執行複雜的用戶流程——這些都變成了簡單的 API 調用。
本文將帶你深入探索 OpenClaw 的瀏覽器自動化能力,從基礎操作到進階場景,從單頁操作到多頁管理,從 Playwright 集成到實戰案例。
一、 核心能力:Browser Automation 101
1.1 瀏覽器控制架構
OpenClaw 的瀏覽器自動化基於 Playwright 框架,提供以下核心能力:
// 核心功能列表
browser-control/
├── snapshot() # 獲取當前頁面快照 (DOM, 狀態, 元素)
├── screenshot() # 截取螢幕截圖 (PNG, JPEG, WebP)
├── navigate() # 導航到指定 URL
├── act() # 執行操作 (click, type, hover, drag, select, fill)
├── console() # 監控控制台日誌
├── pdf() # 生成 PDF
└── dialog() # 處理彈窗/對話框
1.2 基礀操作示例
截圖
// 獲取當前頁面截圖
browser.action('screenshot', {
type: 'png',
path: '/tmp/page-screenshot.png',
fullPage: true
});
導航
// 導航到 URL
browser.action('navigate', {
url: 'https://example.com'
});
獲取快照
// 獲取頁面快照 (包括 DOM, 狀態, 元素)
const snapshot = browser.action('snapshot', {
refs: 'aria', // 使用 ARIA refs (更穩定)
fullPage: true,
depth: 3 // 遞歸深度
});
1.3 元素操作
點擊
// 點擊元素
browser.action('click', {
ref: 'submit-button', // 元素引用 (從 snapshot 獲取)
button: 'left',
modifiers: ['shift'],
doubleClick: false
});
輸入文本
// 輸入文本
browser.action('type', {
ref: 'username-input',
text: 'myusername',
slowly: false,
delayMs: 0
});
滾動
// 滾動頁面
browser.action('press', {
key: 'PageDown',
frame: null
});
二、 Playwright Integration: 高級場景
2.1 Playwright 事件監聽
OpenClaw 的 Playwright 集成支持完整的事件監聽:
// 監控控制台日誌
browser.action('console', {
level: 'log', // log, error, warning, debug
filter: (msg) => msg.text().includes('API')
});
示例:監控 API 請求
// 自定義過濾器
browser.action('console', {
filter: (msg) => {
const text = msg.text();
return text.includes('GET /api') || text.includes('POST /api');
}
});
2.2 多頁管理
OpenClaw 支持多標籤頁管理:
// 獲取所有標籤頁
const tabs = browser.action('tabs', {
limit: 10
});
// 切換到指定標籤頁
browser.action('focus', {
targetId: 'tab-2' // 從 snapshot 獲取
});
// 新增標籤頁
browser.action('open', {
url: 'https://new-tab.com'
});
2.3 場景:自動化表單填寫
// 完整表單自動化流程
async function fillForm(url, formData) {
// 1. 導航到頁面
await browser.action('navigate', { url });
// 2. 獲取頁面快照
const snapshot = await browser.action('snapshot', {
refs: 'aria',
depth: 2
});
// 3. 填寫表單字段
for (const [field, value] of Object.entries(formData)) {
await browser.action('fill', {
ref: snapshot.findField(field),
value,
submit: false
});
}
// 4. 提交表單
await browser.action('click', {
ref: snapshot.findButton('submit')
});
return await browser.action('snapshot');
}
三、 進階技巧:優化與性能
3.1 Ref Selection 策略
ARIA Refs vs Role Refs
// 推薦:使用 ARIA refs (更穩定)
const snapshot = await browser.action('snapshot', {
refs: 'aria' // ARIA refs
});
// 元素定位
const button = snapshot.findButton('submit'); // 通過 name
const input = snapshot.findInput('username'); // 通過 type + name
// 或者使用 Role + Name
const button = snapshot.findElement({ role: 'button', name: 'Submit' });
const link = snapshot.findElement({ role: 'link', name: 'Learn More' });
深度與性能平衡
// 深度控制:避免過度遞歸
const snapshot = await browser.action('snapshot', {
refs: 'aria',
depth: 2, // 適當深度 (1-3)
limit: 50 // 限制元素數量
});
3.2 操作優化
慢速操作
// 為特定元素使用慢速操作
await browser.action('click', {
ref: 'slow-button',
slowly: true, // 逐字點擊 (適合測試)
delayMs: 100 // 每次操作延遲
});
等待策略
// 等待元素出現
await browser.action('wait', {
selector: 'submit-button',
timeoutMs: 5000 // 5秒超時
});
3.3 錯誤處理
// 錯誤處理模板
try {
const snapshot = await browser.action('snapshot', {
refs: 'aria'
});
const button = snapshot.findButton('submit');
if (!button) {
throw new Error('Submit button not found');
}
await browser.action('click', { ref: button.ref });
} catch (error) {
console.error('Browser action failed:', error);
// 重試邏輯
await browser.action('navigate', { url: currentUrl });
throw error;
}

return snapshot;
}
3. 操作去抖動
// 避免頻繁操作
let lastActionTime = 0;
const MIN_DELAY = 500; // 500ms 最小延遲
async function throttledAction(action, params) {
const now = Date.now();
const elapsed = now - lastActionTime;
if (elapsed < MIN_DELAY) {
await new Promise(resolve => setTimeout(resolve, MIN_DELAY - elapsed));
}
lastActionTime = Date.now();
return await browser.action(action, params);
}
5.2 錯誤恢復策略
1. 自動重試
async function retryAction(action, params, maxRetries = 3) {
for (let attempt = 1; attempt <= maxRetries; attempt++) {
try {
return await browser.action(action, params);
} catch (error) {
if (attempt === maxRetries) {
throw error;
}
// 等待後重試
await new Promise(resolve => setTimeout(resolve, 1000 * attempt));
}
}
}
2. 狀態回滾
async function safeAction(action, params) {
const initialState = await browser.action('snapshot', { refs: 'aria' });
try {
return await browser.action(action, params);
} catch (error) {
// 重置狀態
await browser.action('navigate', {
url: initialState.currentUrl
});

5. Best practices and performance optimization
5.1 Performance optimization tips
1. Thread pool management
// 使用 session_yield 避免阻塞
async function parallelScrapes(urls) {
const results = [];
for (const url of urls) {
// 並行執行,但避免過載
const result = await browser.action('navigate', { url });
results.push(result);
}
return results;
}
2. Snapshot cache
// 緩存快照,避免重複獲取
const snapshotCache = new Map();
async function getCachedSnapshot(url) {
if (snapshotCache.has(url)) {
return snapshotCache.get(url);
}
await browser.action('navigate', { url });
const snapshot = await browser.action('snapshot', {
refs: 'aria',
depth: 2
});
snapshotCache.set(url, snapshot);
return snapshot;
}
3. Operation debouncing
// 避免頻繁操作
let lastActionTime = 0;
const MIN_DELAY = 500; // 500ms 最小延遲
async function throttledAction(action, params) {
const now = Date.now();
const elapsed = now - lastActionTime;
if (elapsed < MIN_DELAY) {
await new Promise(resolve => setTimeout(resolve, MIN_DELAY - elapsed));
}
lastActionTime = Date.now();
return await browser.action(action, params);
}
5.2 Error recovery strategy
1. Automatic retry
async function retryAction(action, params, maxRetries = 3) {
for (let attempt = 1; attempt <= maxRetries; attempt++) {
try {
return await browser.action(action, params);
} catch (error) {
if (attempt === maxRetries) {
throw error;
}
// 等待後重試
await new Promise(resolve => setTimeout(resolve, 1000 * attempt));
}
}
}
2. Status rollback
async function safeAction(action, params) {
const initialState = await browser.action('snapshot', { refs: 'aria' });
try {
return await browser.action(action, params);
} catch (error) {
// 重置狀態
await browser.action('navigate', {
url: initialState.currentUrl
});
throw error;
}
}
