Crawler proxy ip address: crawler proxy IP anti-blocking program

Don't let IP blocking choke you! Hands-on with proxy IPs to save your life!

Crawler brothers understand that the most afraid of the target site suddenly give you an IP ban. Like playing the game was banned, the data did not catch the end of the direct cool. Today we will nag some real, teach you how to use the proxy IP with the banning mechanism to fight wisdom and courage.

First, the core logic of proxy IP anti-blocking

In a nutshell.fight a guerrilla warThe other side will definitely be suspicious. If you visit a website 100 times a day using your own broadband, the other party will definitely be suspicious. But if you change your IP address every time you visit, it's like changing your clothes every time you go out, so the site won't recognize you as the same person.

To give a chestnut: do e-commerce price monitoring Zhang San, with their own IP hourly grab a platform data, the third day was blocked. Later, he changed to use ipipgo's dynamic residential IP, randomly switching between different city IPs for each request, and ran steadily for three months.

Second, the proxy IP of the three major practical use

1. IP Pool Rotation Act(suitable for high-frequency acquisition)

import random
import requests

 Proxy pool from ipipgo
proxy_pool = [
    "http://user:pass@192.168.1.1:8080",
    "socks5://user:pass@192.168.1.2:1080"
]

def crawler(url):
    proxy = random.choice(proxy_pool)
    try.
        response = requests.get(url,
            proxies={"http": proxy, "https": proxy}, timeout=10)
            timeout=10)
        return response.text
    except.
        print("Current IP failed, automatically switch to the next one.")

2. Request interval camouflage(with random time delay)

Don't clock in on time like a robot, we recommend a base interval of 3-5 seconds with a random float of ±2 seconds. With ipipgo's client you can set this directly.

3. Request for head obfuscation

Remember to change the User-Agent every time, and don't always use the Python default request header. Here is a pitfall: some sites will check the integrity of the Header, don't just change the UA without handling other parameters.

Third, it is important to choose the right type of agent

IV. Guide to avoiding pitfalls (QA session)

Q: I used a proxy IP and still got blocked?
A: Check three points: ① whether the frequency of IP switching is fast enough ② whether the request parameters are characterized ③ whether the CAPTCHA mechanism is triggered

Q: How to choose between dynamic IP and static IP?
A: If you need to maintain the login status for a long time (e.g. to keep a number), use static, and use dynamic for regular collection. ipipgo's static residence supports binding device fingerprints, which is more stealthy than ordinary proxies.

Q: How do I break the CAPTCHA when I encounter it?
A: It is recommended to add an automatic speed reduction mechanism in the code, or contact ipipgo customer service to open a TK line, which has a higher quality of IP.

V. Why do you recommend ipipgo?

A couple of hardcore advantages of using your own service provider for over two years:
1. Global 200+ countries resources, will not be blind when you need cold area IP
2. support socks5 protocol, more difficult to be recognized than http proxy
3. The client comes with IP warm-up function, the new IP first low-frequency requests to raise weight
4. Customer service can customize the rotation strategy according to the business scenarios, which is more reliable than the common solution.

For those who are just starting out, we recommend theDynamic Residential (Standard) PackageThe first one is for the first time, and the second one is for the second time, and the third one is for the third time. Enterprise users directly on the customized program, we previously do cross-border e-commerce monitoring, they gave the ride to the mixed proxy pool, the blocking rate to 0.3% below.

Lastly, I'd like to say one thing: anti-sealing is a systematic project, and proxy IP is only one of the links. With a reasonable request strategy + anti-anti-crawl measures, in order to long-term stable operation. Encountering specific problems can directly find ipipgo technical brother, they have dealt with a variety of strange cases of blocking, can take a lot less detours.
