How do you play the job of web crawling without rolling over?

Recently, some people always ask Lao Zhang, why his own data capture scripts are blocked? To put it bluntly, it's the same as going to the market to buy food...Don't always put the same face in front of people's booths.The first thing that you need to do is to get your hands on a proxy IP address. Now, but a little bit of the scale of the site, anti-climbing system than the supermarket security door is sensitive, this time to rely on proxy IP to cover.

2026年抓包工具实战排行

Let's talk about the conclusions before we harp on the principles, and after having tested more than two dozen tools in real life, these three are the real deal:

Focus on ScrapyPlus this old buddy, with ipipgo's residential agent, the actual test continuous collection of an e-commerce platform for 3 hours did not trigger the wind control. Configuration key must pay attention to this parameter:

 Sample proxy settings
PROXY_POOL = 'http://user:pass@gateway.ipipgo.com:8000'
DOWNLOAD_DELAY = random.uniform(1.5, 3.2)

Proxy IP well chosen, the program does not alarm in the middle of the night

I've seen too many people planted on free proxies, those who claim not to pay for the IP pool, eight out of ten have long been pulled by the site. ipipgo's enterprise-level program has a wonderful -Automatic switching of exit IPs per requestIt's like playing a game of chicken with stealth on.

To give a real case: the old king of the price comparison system, with ordinary proxy was sealed 30 times a day, replaced with ipipgo exclusive IP package, the failure rate dropped to 1 times a week. Here is a configuration tip:

// The right way to rotate IPs
function rotateProxy() {
  const gateway = 'socks5://dynamic.ipipgo.com:1080';
  // Remember to set a timeout to retry
  request.defaults({timeout: 15000}); }
}

A guide to avoiding the pitfalls of the white man

Three common fatal mistakes newbies make:

1. The request frequency is like a machine gun (more than 3 times per second will result in death).
2. User-Agent is not changed for half a year (no different from entering the exam room with a work license plate)
3. Stick to one IP segment (website risk control is not blind)

Here we recommend ipipgo's intelligent routing function, which automatically adjusts the request characteristics according to the target website. The actual test of a travel platform data crawl, the success rate from 47% directly soared to 89%.

Practical QA Triple Strike

Q: Why does my script work at first and then go dead in a few days?
A: Typical IP pool exposure, it is recommended to switch to ipipgo's pay-as-you-go package, which automatically switches the end segment IP for each request.

Q: What if I need to process a CAPTCHA?
A: ipipgo's high stash of residential IPs can reduce the CAPTCHA trigger rate of 90%, and together with the request header randomization plugin, it can basically bypass most of the detection.

Q: What should I look for in enterprise-level data collection?
A: focus on the SLA guarantee of the proxy service, like ipipgo's B-side service has 99.9% availability commitment, but also with a dedicated technical consultant, more stable than with the public pool.

Say something from the heart.

This line of work is the most taboo is greedy for cheap, last year, a customer figure to save money with a free agent, the results of the collection of commodity price data all wrong, directly leading to the promotional strategy overturned. Now people honestly use ipipgo business package, data quality and then did not have a problem.

A final word of advice:Web crawling is essentially a constant battle, don't expect one set of configurations to eat everything. Regularly update your IP strategy and pay more attention to technical updates from service providers like ipipgo to survive in this business.
