When crawler meets anti-crawler: how to break this cat-and-mouse game?
Do data crawl friends have recently found that the site's anti-climbing measures more and more "chicken thief". In the past, the fixed IP can still be mixed for a few days, and now just climb half an hour to be blocked. This time we have to move out of our killer - proxy IP. but the ordinary proxy with a lot of bad use.Machine Learning Trained Anti-Crawl System, can now instantly recognize crawlers by dozens of features.
How does machine learning uncover crawlers?
Nowadays, websites will use these tricks to catch crawlers:
| test dimension | concrete expression |
|---|---|
| temporal regularity | Requested on time every 5 seconds |
| mechanical | Tap without sliding the page |
| device fingerprint | Browser parameters are identical |
For example, the anti-climbing model of an e-commerce site, found that a certain IP in the early morning at 3:00 a.m. continued to visit the cell phone category page, each time to stay for 18 seconds exactly, immediately triggering the verification code. At this time, if you switch to ipipgo's dynamic residential IP, the request interval is automatically randomized in 3-15 seconds, and the device fingerprints are replaced in real time, you can perfectly disguise the real person.
Proxy IP's Four Tips for Breaking Defense
1. The IP pool should be deep enough: ipipgo's global pool has 80 million + residential IPs, and each request looks like a user from a different region is accessing the : 4G/5G mobile IPs are harder to identify than server room IPs A common mistake newbies make isDriving an agent and thinking everything's fine.. Last week a client used a certain proxy and still got blocked. We troubleshooted and found that although they changed their IP, all requests carried the same cookie. later changed to ipipgo'sAll-link anonymization programThe survival rate is directly increased to 92% by automatically clearing browser traces every time you connect. Q: Which is better, dynamic IP or static IP? Q: What do I do when I encounter a CAPTCHA? Q: Why do you recommend ipipgo? Lastly, I would like to remind you that anti-climbing is essentially a cost game. Instead of struggling to crack the detection model of each site, it is better to use ipipgo this kind of professional service providers, the technical difficulties to them to deal with. After all, they have a specialized anti-reverse team in the research of the major platforms algorithm updates, the ordinary developers to toss their own too time-consuming.
2. Be smart about switching strategies: Don't be silly and change IPs per page, adjust dynamically according to the response status code
3. The network environment should be real
4. Behavioral trajectory to be simulated: with the simulation of the mouse movement trajectory, do not always straight line click!Three guides to avoiding pitfalls in the real world
Frequently Asked Questions
A: Dynamic IP is more suitable for high-frequency request scenarios, like ipipgo's short-lived proxy is a new IP every time, which is more difficult for anti-climbing systems to track
A: Suggest two options: 1) Reduce the frequency of requests 2) Access the coding platform. With ipipgo's IP rotation, it can reduce 70%'s CAPTCHA triggering
A: Three hardcore advantages: 1) exclusive mobile base station resources 2) real-time monitoring of IP survival status 3) support for socks5 proxy protocol. Especially theirIntelligent Routing EngineIt can automatically select the fastest line and speed up 40% compared with ordinary agents.
