Playwright stealth mode in action: a full account of bypassing reCAPTCHA authentication

When the crawler meets the CAPTCHA: those years we have stepped on the pits

Friends engaged in data capture know that encounter reCAPTCHA validation is like eating an apple and biting a worm - both disgusting and helpless. Last week to help a friend deal with an e-commerce platform price monitoring, for three consecutive days by the CAPTCHA interception, so angry that he almost smashed the keyboard. This is the time to offer ourTwin Sword Stream Combination Technique: Playwright stealth mode + ipipgo proxy IP.

Why does CAPTCHA always focus on you? IP characteristics betray you.

The top three killers for platforms to recognize crawlers:Request Frequency, Behavioral Trajectory, IP Profiling. The first two can be solved with Playwright's stealth mode, but the IP problem must be solved by proxies. Ordinary proxies are like utility slippers - anyone can wear them, and the result is IPs marked with red crosses.

Four Steps to Practice: To Hell with CAPTCHAs

Step 1: Environmental camouflage should be in place
Load ipipgo's proxy configuration on Playwright startup, and remember to add user-agent random generation. Don't use those off-the-shelf UA libraries, it's more reliable to write your own permutation script.

Step 2: Operate at a natural rhythm
Never let the mouse go in a straight line! Insert a random 200-800ms pause between click and type events to simulate acceleration effect when scrolling the page. It's like chasing a girl, too much monkey around is sure to get pulled.

Boo #3: There's something to be said for IP rotation
Recommended by ipipgoOn-demand mode switchingIf you encounter CAPTCHA, disconnect immediately and retry with a new IP. Be careful to clear the local cache and don't leave fingerprints.

Step 4: Handle Failure with Grace
Setting up 3 retries, automatically switching city nodes after failure. ipipgo's API supports specifying operators, such as disguising as "China Mobile 4G" as a real user label.

Guide to avoiding pitfalls: don't overlook these details

- Don't use headless mode! It saves resources, but it's easy to detect.
- Browser fingerprints to be changed to full set, including time zone, language, screen resolution
- Don't close your browser when you encounter a CAPTCHA, first use ipipgo'sEmergency IP changefunctionality
- Updating the proxy IP pool once a week is like changing your underwear.

QA time: situations you might encounter

Q: What should I do if my proxy IP is slow?
A: In ipipgo background switching protocols, HTTP replaced by socks5. measured download speed can be increased 40%, like a water pipe for the booster pump.

Q: Always triggering a CAPTCHA at some point?
A: Check the add-ons for that page, it could be that the WebGL fingerprint is exposed. Add -disable-webgl to the Playwright startup parameters.

Q: How can I recover quickly after my IP is blocked?
A: Immediately hack the IP in the ipipgo console, the system will automatically compensate for the new IP. remember to clear the local cookies and storage at the same time!

One last word of caution: don't die on captcha recognition, use ipipgo'sResidential Proxy + Traffic IsolationThe program is the king. Their dynamic IP pool covers 200+ cities, and even the broadband account to which the IP belongs is real in the network, which disguise degree is comparable to secret agent level of disguise.
