Puppeteer with Crawlera Proxy

Question

I am not able to make a puppeteer request through a proxy that has authentication.

Have tried both proxy url authentication: --proxy-server=u:[email protected]:8010

And also the puppeteer page.authenticate(u,p)

still getting ERR_NO_SUPPORTED_PROXIES

my code:

require('dotenv').config();
const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch({
    ignoreHTTPSErrors: true,
    args: ['--proxy-server=proxy.crawlera.com:8010']
  });

  const page = await browser.newPage();
  await page.setExtraHTTPHeaders({
    'Proxy-Authorization':
      'Basic ' +
      Buffer.from(`${process.env.CRAWLERA_APIKEY}:`).toString('base64')
  });

  page.on('console', (...args) => console.log('PAGE LOG:', ...args));
  const path = `https://www.andersonassociates.net/`;
  await page.setViewport({ width: 1680, height: 895 });

  try {
    console.log('before-goto', path);
    var start = +new Date();
    var resp = await page.goto(path, {
      timeout: 0,
      waitUntil: 'domcontentloaded'
    });

    console.log('after-goto', path);
    var end = +new Date();
    console.log('start-end-diff', (end - start) / 1000);

    if (!resp.ok) {
      browser.close();
      return { status: resp.status, error: `ASIN NOT OK. ${resp.status}` };
    }
    console.log('goto', path);
  } catch (error) {
    console.log('page.goto ERROR', error.stack.split('\n'));
    browser.close();
    return { error: error.toString(), stack: error.stack.split('\n') };
  }

  try {
    await page.screenshot({ path: `tmp/anderson.png`, fullPage: true });
    console.log('screenshot');
    browser.close();
  } catch (e) {
    browser.close();
    console.log('screenshot error', e.stack.split('\n'));
  }
})();

I used Crawlera as my proxy service too, already used proxy-chain & page.authenticate method, but no luck, I think it is caused Crawlera provides an empty password, and I solved by using page.setExtraHTTPHeaders:

const browser = await puppeteer.launch({
    ignoreHTTPSErrors: true, // To allow https url
    args: ['--proxy-server=proxy.crawlera.com:8010']
});
const page = await browser.newPage();
await page.setExtraHTTPHeaders({
    'Proxy-Authorization': 'Basic ' + Buffer.from('<APIKEY>:').toString('base64'),
});

Hope this helps.

You can use proxy-chain npm package for it.

Example:

const puppeteer = require('puppeteer');
const proxyChain = require('proxy-chain');

(async() => {
    const oldProxyUrl = 'http://u:[email protected]:8010';
    const newProxyUrl = await proxyChain.anonymizeProxy(oldProxyUrl);

    // Prints something like "http://127.0.0.1:45678"
    console.log(newProxyUrl);

    const browser = await puppeteer.launch({
        args: [`--proxy-server=${newProxyUrl}`],
    });

})();
