How to use proxy in puppeteer and headless Chrome?

问题

Please tell me how to properly use a proxy with a puppeteer and headless Chrome. My option does not work.

const puppeteer = require('puppeteer');
(async () => {
  const argv = require('minimist')(process.argv.slice(2));

  const browser = await puppeteer.launch({args: ["--proxy-server =${argv.proxy}","--no-sandbox", "--disable-setuid-sandbox"]});
  const page = await browser.newPage();

  await page.setJavaScriptEnabled(false);
  await page.setUserAgent(argv.agent);
  await page.setDefaultNavigationTimeout(20000);
  try{
  await page.goto(argv.page);

  const bodyHTML = await page.evaluate(() => new XMLSerializer().serializeToString(document))
  body = bodyHTML.replace(/\r|\n/g, '');
  console.log(body);
}catch(e){
        console.log(e);
}
  await browser.close();
})();

You can find an example about proxy at here

'use strict';

const puppeteer = require('puppeteer');

(async() => {
  const browser = await puppeteer.launch({
    // Launch chromium using a proxy server on port 9876.
    // More on proxying:
    //    https://www.chromium.org/developers/design-documents/network-settings
    args: [ '--proxy-server=127.0.0.1:9876' ]
  });
  const page = await browser.newPage();
  await page.goto('https://google.com');
  await browser.close();
})();

if you want to use different proxy for per page, try this, use https-proxy-agent or http-proxy-agent to proxy request for per page

回答3:

do not use

"--proxy-server =${argv.proxy}"

this is a normal string instead of template literal
use ` instead of "

`--proxy-server =${argv.proxy}`

otherwise argv.proxy will not be replaced
check this string before you pass it to launch function to make sure it's correct and you may want to visit http://api.ipify.org/ in that browser to make sure the proxy works normally
