问题

I tried:

const browser = await puppeteer.launch({args: ['--enable-webrtc-stun-origin=false', '--enforce-webrtc-ip-permission-check=false']});

But this is not working. Next I tried:

const targets = await browser.targets();
const backgroundPageTarget = targets.find(target => target.type() === 'background_page');
const backgroundPage = await backgroundPageTarget.page();
await backgroundPage.evaluateevaluateOnNewDocument(() => {
  chrome.privacy.network.webRTCIPHandlingPolicy.set({
    value: "default_public_interface_only"
  });
});

But got:

TypeError: Cannot read property 'page' of undefined

EDIT: Need solution for {headless: true}.

回答1:

Here are steps to prevent webrtc IP leak on puppeteer version 1.9.0.

Note:

Background Pages are available for chrome extensions. You won't probably find a background page on a headless browser.
Chrome headless does not support extensions. We must use headless: false.

Solution: WebRTC Leak Prevent

Clone the git repo to some local folder (ie: extensions/webrtc),

git clone https://github.com/aghorler/WebRTC-Leak-Prevent extensions/webrtc

Use it inside your code,

const puppeteer = require('puppeteer');

async function helloWorld() {
  // load the extension
  const extensionPath = 'extensions/webrtc';
  const browser = await puppeteer.launch({
    // must be non-headless
    headless: false,
    args: [
      `--disable-extensions-except=${extensionPath}`,
      `--load-extension=${extensionPath}`,
    ],
  });

  const page = await browser.newPage();

  // test it with browserleaks.com
  await page.goto('https://browserleaks.com/webrtc');

  // psss: just me hiding my details
  await page.evaluate(() => $('#rtc-ipv4 a').css('-webkit-filter', 'blur(5px)'));

  // taking evidence
  await page.screenshot({ path: 'screenshots/browserleaks.png' });

  await browser.close();
}

helloWorld();

Result:

Advanced Stuff

If you want to quickly hide both Public and Private IP from webRTC, modify this (extensions/webrtc/background.js) line to disable_non_proxied_udp,
