Node puppeteer Page.$x xpath使用

async function scrapeChannel(url) {

  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto(url);

  const [el] = await page.$x('/html/body/ytd-app/div/ytd-page-manager/ytd-browse/div[3]/ytd-c4-tabbed-header-renderer/app-header-layout/div/app-header/div[2]/div[2]/div/div[1]/div/div[1]/ytd-channel-name/div/div/yt-formatted-string');
  const text = await el.getProperty('textContent');
  const name = await text.jsonValue();

  const [el2] = await page.$x('//*[@id="img"]');
  const src = await el2.getProperty('src');
  const avatarURL = await src.jsonValue();

  browser.close();

  return {name, avatarURL}
  
}

• page.$x 返回节点的数组对象
• el.getProperty 获取节点属性对应的值
