如何从 chrome 获取 DOM.shadowRootPushed 事件？

问题描述

我一直在尝试使用 DOM.shadowRootPushed 中的 CDPSession 获取 puppeteer 事件。这是加载包含 shadowRoot 的页面：

<html>
<head>
  <title>
    Page with Shadow Root
  </title>
</head>
<body>
  <header id="host">
    <h1>Hello DOM</h1>
  </header>
</body>
<script>
  var attachShadow = HTMLElement.prototype.attachShadow

  HTMLElement.prototype.attachShadow = function ( option )
  {
    var sh = attachShadow.call( this,option )
    console.info( '%s shadow attached to %s',option.mode,this )
    //add a MutationObserver here
    return sh
  }
  setTimeout(function() {
    const host = document.getElementById('host');
    const shadowRoot = host.attachShadow({mode: 'open'});
    shadowRoot.innerHTML = '<h1>Hello Shadow DOM</h1>';
  },3300);
</script>
</html>

而且，我使用这个脚本来获取事件：

const puppeteer = require('puppeteer');

(async() => {
  // Use Puppeteer to launch a browser and open a page.
  const browser = await puppeteer.launch({
      headless: false
      // userDataDir: "/home/w/.config/chromium/"
    });
  const page = await browser.newPage();

  // Create a raw DevTools protocol session to talk to the page.
  // Use CDP to set the animation playback rate.
  const session = await page.target().createCDPSession();
  await session.send('Animation.enable');
  await session.send('DOM.enable');
  
  session.on('Animation.animationCreated',() => {
    console.log('Animation created!');
  });
  session.on('DOM.shadowRootPushed',() => {
    console.log('DOM.shadowRootPushed');
  });
  session.on('DOM.shadowRootPopped',() => {
    console.log('DOM.shadowRootPopped');
  });

  await session.send('Animation.setPlaybackRate',{
    playbackRate: 2,});


  // Check it out! Fast animations on the "loading..." screen!
  // await page.goto('https://pptr.dev');
  await page.goto('http://localhost:8000');
  await wait(1115000)
  console.log("Done")
})();

async function wait(ms) {
  return new Promise(resolve => setTimeout(resolve,ms));
}

不过我得到了 Animation.animationCreated。 CDP 网站说 DOM.shadowRootPushed 是一个实验性事件。是否需要在启动选项中传递标志？依赖项：

  "dependencies": {
    "puppeteer": "8.0.0","ws": "7.2.3"
  },

Chrome Version：版本 90.0.4427.0（开发者版本）（64 位）

更新：

根据评论，我添加了以下标志：

args: [
        '--enable-blink-test-features','--enable-experimental-web-platform-features','--fake-variations-channel=canary'
      ]

并为 dev 应用 beta、canary、stable、--fake-variations-channel。未捕获通知。
