node.js - How to avoid being detected as bot on Puppeteer and Phantomjs?

Question

Puppeteer and PhantomJS are similar. The issue I'm having is happening for both, and the code is also similar.

I'd like to catch some informations from a website, which needs authentication for viewing those informations. I can't even access home page because it's detected like a "suspicious activity", like the SS: https://i.imgur.com/p69OIjO.png

I discovered that the problem doesn't happen when I tested on Postman using a header named Cookie and the value of it's cookie caught on browser, but this cookie expires after some time. So I guess Puppeteer/PhantomJS both are not catching cookies, because this site is denying the headless browser access.

What could I do for bypass this?

// Simple Javascript example
var page = require('webpage').create();
var url = 'https://www.expertflyer.com';

page.open(url, function (status) {
    if( status === "success") {
        page.render("home.png");
        phantom.exit();
    }
});

If anyone need in future for the same problem. Using puppeteer-extra

I have tested the code on a server. On 2nd run there is google Captcha. You can solve it your self and restart the bot or use a Captcha solving service.

I did run the code more than 10 times there is no ip ban. I did not get captcha again on my continues run.

But you can get captcha again!

//sudo npm install puppeteer puppeteer-extra puppeteer-extra-plugin-stealth puppeteer-extra-plugin-adblocker readline
var headless_mode = process.argv[2]

const readline = require('readline');
const puppeteer = require('puppeteer-extra')
const StealthPlugin = require('puppeteer-extra-plugin-stealth')
puppeteer.use(StealthPlugin())
const AdblockerPlugin = require('puppeteer-extra-plugin-adblocker')
puppeteer.use(AdblockerPlugin({ blockTrackers: true }))


async function run () {
  const browser = await puppeteer.launch({
    headless:(headless_mode !== 'true')? false : true,
    ignoreHTTPSErrors: true,

  }
}


  await browser.close()
}
run();

Please note "Solve the captcha and type yes to continue: " method not working as expected, Need some fixing.

Edit: Re-run the bot after 10 minutes got captcha again. Solved captcha on chrome://inspect/#devices restarted the bot, everything working again. No ip ban.
