我一直在尝试使用from来获取DOM.shadowRootPushed事件。这是加载的页面包含 shadowRoot：CDPSessionpuppeteer
<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，我正在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));
}
我明白了Animation.animationCreated。CDP 网站称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"

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'
]
并应用dev, beta, canary,stable为--fake-variations-channel. 未捕获通知。
