Bypassing CAPTCHAs With Headless Chrome Using Puppeteer


Answer :

Try generating random useragent using this npm package. This usually solves the user agent-based protection.

In puppeteer pages can override browser user agent with page.setUserAgent

var userAgent = require('user-agents'); ... await page.setUserAgent(userAgent.toString())

Additionally, you can add these two extra plugins,

puppeteer-extra-plugin-recaptcha - Solves reCAPTCHAs automatically, using a single line of code: page.solveRecaptchas()

NOTE: puppeteer-extra-plugin-recaptcha uses a paid service 2captcha

puppeteer-extra-plugin-stealth - Applies various evasion techniques to make detection of headless puppeteer harder.


Here is a list of things I'm doing to bypass the captchas and similar blockings:

  • Enable stealth mode (via puppeteer-extra-plugin-stealth)
  • Randomize User-agent or Set a valid one (via random-useragent)
  • Randomize Viewport size
  • Skip images/styles/fonts loading for better performance
  • Pass "WebDriver check"
  • Pass "Chrome check"
  • Pass "Notifications check"
  • Pass "Plugins check"
  • Pass "Languages check"

    const randomUseragent = require('random-useragent');      //Enable stealth mode     const puppeteer = require('puppeteer-extra')     const StealthPlugin = require('puppeteer-extra-plugin-stealth')     puppeteer.use(StealthPlugin())          const USER_AGENT = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.75 Safari/537.36';          async function createPage (browser,url) {          //Randomize User agent or Set a valid one         const userAgent = randomUseragent.getRandom();         const UA = userAgent || USER_AGENT;         const page = await browser.newPage();          //Randomize viewport size         await page.setViewport({             width: 1920 + Math.floor(Math.random() * 100),             height: 3000 + Math.floor(Math.random() * 100),             deviceScaleFactor: 1,             hasTouch: false,             isLandscape: false,             isMobile: false,         });          await page.setUserAgent(UA);         await page.setJavaScriptEnabled(true);         await page.setDefaultNavigationTimeout(0);          //Skip images/styles/fonts loading for performance         await page.setRequestInterception(true);         page.on('request', (req) => {             if(req.resourceType() == 'stylesheet' || req.resourceType() == 'font' || req.resourceType() == 'image'){                 req.abort();             } else {                 req.continue();             }         });          await page.evaluateOnNewDocument(() => {             // Pass webdriver check             Object.defineProperty(navigator, 'webdriver', {                 get: () => false,             });         });          await page.evaluateOnNewDocument(() => {             // Pass chrome check             window.chrome = {                 runtime: {},                 // etc.             };         });          await page.evaluateOnNewDocument(() => {             //Pass notifications check             const originalQuery = window.navigator.permissions.query;             return window.navigator.permissions.query = (parameters) => (                 parameters.name === 'notifications' ?                     Promise.resolve({ state: Notification.permission }) :                     originalQuery(parameters)             );         });          await page.evaluateOnNewDocument(() => {             // Overwrite the `plugins` property to use a custom getter.             Object.defineProperty(navigator, 'plugins', {                 // This just needs to have `length > 0` for the current test,                 // but we could mock the plugins too if necessary.                 get: () => [1, 2, 3, 4, 5],             });         });          await page.evaluateOnNewDocument(() => {             // Overwrite the `languages` property to use a custom getter.             Object.defineProperty(navigator, 'languages', {                 get: () => ['en-US', 'en'],             });         });          await page.goto(url, { waitUntil: 'networkidle2',timeout: 0 } );         return page;     }


Have you tried setting the browser agent?

await page.setUserAgent('5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36');

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
