# 管理浏览器会话

## 关闭会话

自动化任务完成后，请务必关闭会话，以释放云端资源，避免触及并发数上限。

```javascript Puppeteer theme={null}
await browser.close();
```

```python Playwright theme={null}
await browser.close()
```

## 在多次操作中复用会话

每次调用 `puppeteer.connect()` 或 `connect_over_cdp()` 都会启动一个新会话。如果你需要按顺序执行多个操作（例如在 Agent 工作流中），请复用同一个连接，否则 Cookie、本地存储和页面状态会在各步骤之间丢失。

**推荐模式：会话单例**

```javascript Puppeteer theme={null}
// session.js
const puppeteer = require('puppeteer-core');

let _browser = null;
let _page = null;

async function getSession(token, profileId) {
  if (_browser && _browser.isConnected()) {
    return { browser: _browser, page: _page };
  }

  const url = `https://cloudbrowser.gologin.com/connect?token=${token}&profile=${profileId}`;
  _browser = await puppeteer.connect({ browserWSEndpoint: url, defaultViewport: null });
  const pages = await _browser.pages();
  _page = pages[0] || await _browser.newPage();

  return { browser: _browser, page: _page };
}

async function closeSession() {
  if (_browser) {
    await _browser.close();
    _browser = null;
    _page = null;
  }
}

module.exports = { getSession, closeSession };
```

```python Playwright theme={null}
# session.py
from playwright.async_api import async_playwright, Browser, Page

_browser: Browser | None = None
_page: Page | None = None
_playwright = None

async def get_session(token: str, profile_id: str):
    global _browser, _page, _playwright

    if _browser and _browser.is_connected():
        return _browser, _page

    url = f'https://cloudbrowser.gologin.com/connect?token={token}&profile={profile_id}'
    _playwright = await async_playwright().start()
    _browser = await _playwright.chromium.connect_over_cdp(url)
    pages = _browser.contexts[0].pages if _browser.contexts else []
    _page = pages[0] if pages else await _browser.new_page()

    return _browser, _page

async def close_session():
    global _browser, _page, _playwright
    if _browser:
        await _browser.close()
    if _playwright:
        await _playwright.stop()
    _browser = None
    _page = None
    _playwright = None
```

## 处理断开连接

网络中断或云端超时都可能导致连接断开。请在每次操作前检查连接状态，并在需要时重新连接：

```javascript Puppeteer theme={null}
if (!browser.isConnected()) {
  // reconnect
  const { browser: b, page: p } = await getSession(token, profileId);
}
```

## 并发

每个活跃的会话都会占用你所在套餐的并发数额度。为避免出现错误：

* 使用完毕后请及时关闭会话
* 不要同时从多个进程连接同一个配置文件
