如果你能为Node.js编写脚本，这里有一个使用puppeteer库的小例子。它在页面加载到无头（不可见）Chrome后记录页面源代码，并通过页面脚本生成动态内容：

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch({ headless: false, defaultViewport: null });

try {
  const [page] = await browser.pages();
  await page.goto('https://example.org/');
  console.log(await page.content());

} catch (err) { console.error(err); } finally { await browser.close(); }

字符串

我提请您注意绕过保护cloudflare的代码和库：
库：

npm i puppeteer-extra puppeteer-extra-plugin-stealth puppeteer

字符串
nodejs：

const puppeteer = require('puppeteer-extra')
const pluginStealth = require('puppeteer-extra-plugin-stealth')
const { executablePath } = require('puppeteer')

const link = 'https://www.g2.com/'

const getHtmlThoughCloudflare = async (url) => {
  puppeteer.use(pluginStealth())
  const result = await puppeteer
    .launch({ headless: true })
    .then(async (browser) => {
      const page = await browser.newPage()
      await page.goto(url)
      const html = await page.content()
      await browser.close()
      return html
    })

  console.log(` HTML: ${result}`)
  return result // html
}

getHtmlThoughCloudflare(link)
