Puppeteer Delete Navigator.Webdriver

Question

I m using puppeteer for scraping. I can pass navigator.webdriver property= false but i need to delete that prop completely.

https://bot.sannysoft.com/

I tried with passing false to navigator.webdriver. This trick can pass on https://intoli.com/blog/not-possible-to-block-chrome-headless/chrome-headless-test.html

but in https://bot.sannysoft.com/ cant.

here is webpage testing bot. This test is looking for are there any "webdriver" prop in navigator object. Doesn't care if its true or false. I need to remove this webdriver prop from browser.

not yet, waiting for a friend – Ali Haydar Güleç Feb 20 '19 at 12:19 — Ali Haydar Güleç, Feb 20 '19 at 12:19

Try this:

const newProto = navigator.__proto__;
delete newProto.webdriver;
navigator.__proto__ = newProto;

@Matrix because in normal browsers this is not defined. – Chad Cache Oct 08 '19 at 11:57
here for example: page.evaluateOnNewDocument(pageFunction[, ...args]); your code should be inside "pageFunction" – Nodarius Feb 04 '20 at 14:18

Since I can't comment, I'll leave an answer:

I had the same question, and @Nodarius's answer worked for me. Since you didn't accept it, I assume your problem is still persisting.

This is probably because, even if you run in, you need that code to run before the page loads (or before the website accesses the variable).

I achieved this using a proxy (https://mitmproxy.org/) which loads the script before the page loads.

Hope it helps.

await page.evaluateOnNewDocument(() => {
  window.navigator = {}
})

await page.evaluateOnNewDocument(() => {
    Object.defineProperty(navigator, "webdriver", {
      get: () => false,
    });
});
