Anti-Crawl Counter Library: Random Header Generator

Teach you to use a random Header + proxy IP to break through the anti-climbing

engaged in data crawling friends should have encountered this situation: obviously using a proxy IP, the site can still recognize you as a crawler. At this time, you have to work on the request header (Header) - but many people do not know that theChanging a few parameters alone won't help., have to work with proxy IPs to do the whole package.

The secret at the heart of the Header generator

Many tutorials teach people to change the User-Agent on the end of the matter, in fact, modern anti-climbing system will detect 20 + Header parameters. Here is a tested and effective configuration program:

Be careful not to use ready-made libraries on the Internet, write your own random generator is reliable. For example, User-Agent should be distinguished:

Chrome version tailUse odd numbers (the official version is all even)
Windows version numberTo include non-mainstream versions (e.g. Win7 SP2)

Hidden Usage of Proxy IP

It's not enough to just change the IP, you have to adjust the Header according to the IP type. for example when using ipipgo's residential proxy:

1. Backcasting carriers from IP addresses (Mobile/Unicom/Telecom)
2. Setting time zone parameters according to geographic location
3. Matching equipment models commonly used in the region

As a chestnut, when using the IP of Guangdong Mobile, it should appear in the Header:

"X-Forwarded-For": "120.230.95.xx",
"Accept-Language": "zh-CN,zh;q=0.9",
"User-Agent": "Mozilla/5.0 (Linux; U; Android 10) Mobile M2004J19C"

That's how you configure it so it doesn't show.

Recommended for ipipgoDynamic Residential Agents, their IP pool has three major advantages:

• Automatic IP + port change per session
• Supports camouflage by city-level location
• Header validation tool (this is super useful)

Real-world configuration scenarios:

1. Get new IP before each request
2. Generate corresponding Header based on IP information
3. 设置0.5-3秒的随机
4. Replacement of a monthly batch of commonly used equipment fingerprints

Frequently Asked Questions

Q: Do I need to maintain my own IP pool?
A: Never! Use a professional service provider like ipipgo, they update 200,000+ IPs every day, it's costly to maintain it yourself and also prone to problems.

Q: Do free proxies work?
A: Tearful lesson! The Header of free proxies has long been flagged by anti-crawling systems, and using it once triggers validation.

Q: How do I detect if the camouflage is in effect?
A: ipipgo has a simulation detection function in the background that returns the risk level identified for the current request.

Finally, we are reminded that anti-climbing confrontation is an ongoing process. It is recommended to update the Header policy once a month, and with ipipgo's dynamic IP service, it can basically solve the 90% blocking problem. Partners who are new to it can directly use theirIntelligent Anti-Reclimbing Package, already has these configuration options built in as stated in this article.
