我试图在我的 Python 程序中通过 Pyppeteer 抓取搜索结果的 url，但它不起作用......这是我的代码：

import asyncio
from pyppeteer import launch

URL = 'https://hk.appledaily.com/search/apple'

async def main():
    browser = await launch()
    page = await browser.newPage()
    await page.goto(URL)

    await page.waitForSelector(".flex-feature")

    elements = await page.querySelectorAll('.flex-feature')

    for el in elements:
        text = await page.evaluate('(el) => el.innerHTML.querySelectorAll("story-card")', el)
        print(text)

    await browser.close()

asyncio.get_event_loop().run_until_complete(main())

希望任何人都可以提供帮助！谢谢！

对不起愚蠢的问题！我现在已经做到了。。哈哈。。

import asyncio
from pyppeteer import launch

# https://pypi.org/project/pyppeteer/

URL = 'https://hk.appledaily.com/search/apple'


async def main():
    browser = await launch()
    page = await browser.newPage()
    await page.goto(URL)

    await page.waitForSelector(".flex-feature")

    elements = await page.querySelectorAll('.flex-feature')
    elements = await page.querySelectorAll('.story-card')

    for el in elements:
        text = await page.evaluate('(el) => el.textContent', el)
        text2 = await page.evaluate('(el) => el.href', el)
        print(text2)

    await browser.close()

asyncio.get_event_loop().run_until_complete(main())

结果将是：
