有没有办法在pyppeteer中滚动到页末？

import asyncio
from pyppeteer import launch

async def scroll_to_bottom():
    browser = await launch()
    page = await browser.newPage()
    await page.goto('https://example.com')  # 替换为需要滚动的网页地址

    # 获取页面高度
    page_height = await page.evaluate('''
        () => {
            const { body } = document;
            const html = document.documentElement;
            return Math.max(body.scrollHeight, body.offsetHeight,
                html.clientHeight, html.scrollHeight, html.offsetHeight);
        }
    ''')

    # 持续滚动直到达到页末
    while True:
        # 滚动到当前页面底部
        await page.evaluate('window.scrollTo(0, document.body.scrollHeight)')

        # 等待页面加载新内容
        await asyncio.sleep(1)

        # 获取滚动后页面的当前高度
        new_page_height = await page.evaluate('''
            () => {
                const { body } = document;
                const html = document.documentElement;
                return Math.max(body.scrollHeight, body.offsetHeight,
                    html.clientHeight, html.scrollHeight, html.offsetHeight);
            }
        ''')

        # 判断页面是否已经滚动到页末
        if new_page_height == page_height:
            break
        else:
            page_height = new_page_height

    await browser.close()

# 使用异步方式运行滚动函数
asyncio.get_event_loop().run_until_complete(scroll_to_bottom())

pip install pyppeteer
