<p>我正在尝试使用node.js和puppeteer爬取一个网站以获取实时足球信息，但是在console.log("trying to select team element")之后，我的浏览器立即关闭。</p> <pre class="brush:php;toolbar:false;">const puppeteer = require("puppeteer"); async function openPage() { const browser = await puppeteer.launch( {headless: true} ); const page = await browser.newPage(); await page.setViewport({ width: 1000, height: 926 }); await page.goto("https://www.livescore.com/en/"); // 接受cookies const button = await page.waitForSelector('#onetrust-accept-btn-handler'); if (button) { await button.click(); console.log("clicked cookie button"); }; return page; } async function scrapeData(page) { let content = []; // 获取比赛元素 let elements = await page.waitForSelector(".Ip") console.log("trying to select team element") for (let i=0; i &lt; elements.length; i++) { let homeTeamElement = await elements[i].$(".Ip") if (homeTeamElement) { const homeTeamText = await homeTeamElement.evaluate(node =&gt; node.textContent); content.push(homeTeamText); } }; return content; }; (async () =&gt; { const page = await openPage(); const dataScraped = await scrapeData(page); console.log(dataScraped) await page.browser().close(); })();</pre> <p>对于为什么会这样以及对我的代码的进一步批评，欢迎提出任何想法！</p>

const puppeteer = require("puppeteer"); // ^21.0.2

const url = "";

let browser;
(async () => {
  browser = await puppeteer.launch();
  const [page] = await browser.pages();
  await page.setViewport({width: 1000, height: 926});
  await page.goto(url, {waitUntil: "domcontentloaded"});

  // not really necessary
  const button = await page.waitForSelector("#onetrust-accept-btn-handler");
  await button.click();

  await page.waitForSelector(".Ip");
  const content = await page.$$eval(".Ip", els =>
    els.map(e => {
      const text = id =>
        e.querySelector(`[id*=${id}]`).textContent.trim();
      return {
        time: text("status-or-time"),
        home: text("home-team-name"),
        away: text("away-team-name"),
        homeTeamScore: +text("home-team-score"),
        awaitTeamScore: +text("away-team-score"),
      };
    })
  );
  console.log(content);
})()
  .catch(err => console.error(err))
  .finally(() => browser?.close());
