Crawler proxy ip: crawler dedicated proxy ip configuration anti-blocking strategy

Crawler proxy ip anti-blocking core logic

The biggest headache of crawlers is to be blocked by the target site's IP, right? Actually, it's like playing hide-and-seek.The key is to make sure the site doesn't recognize you as the same person.The first thing you need to do is to use a proxy IP to change your armor. Using a proxy IP is equivalent to changing your own armor, but changing your armor is not enough, you have to be strategic.

To cite a chestnut, some brothers directly take the free agent hard to dislike, the results of half an hour to be sealed to the mother do not recognize. Here is a misunderstanding:Proxy IP quality is more important than quantityJust like when you go to the market to buy vegetables. It's like when you go to the market and buy a basket of rotten leaves rather than picking a few fresh vegetables.

Three Iron Laws of Proxy IP Selection

There are all sorts of agent types on the market, and it's always good to remember these three principles:

Like our own.ipipgo's dynamic residential packagesThe 7$ more 1G traffic is enough and cheap. A friend doing e-commerce use it to climb the competitor's data, continuous running for a month did not turn over.

Practical Configuration Tips

Here's a Python example, note the comments section:

import requests
from itertools import cycle

 API extraction link from ipipgo backend
proxy_api = "https://api.ipipgo.com/getproxy?key=你的密钥"

def get_proxies():
     It is recommended to fetch 5-10 IPs at a time for backup
    proxies = requests.get(proxy_api).json()['data']
    return cycle(proxies) make a cycle pool

proxy_pool = get_proxies()

for _ in range(20): current_proxy = next(proxy)
    current_proxy = next(proxy_pool)
    try: current_proxy = next(proxy_pool)
        resp = requests.get('target url', 'current_proxies={"http": current_proxy_pool
                          proxies={"http": current_proxy, "https": current_proxy},
                          timeout=8,
                          headers=randomHeader()) This function is implemented by itself
        print("Successfully fetching data")
    except.
        print(f"{current_proxy} failed, automatically switching to the next one")

Here's the point:Don't be a fool and use the IPs in order.Random disruption + failure cullingThat's the way to go. Just like playing mahjong, you can't always play the cards in the order of southeast, northwest, and north-west.

Anti-Blocking Strategy Combination

It's not enough to just change the IP, you have to go along with these tawdry maneuvers:

• Request interval randomization (0.5-3 seconds float)
• User-Agent rotation (don't just use Chrome!)
• Simulate mouse trajectory (when doing js rendering)
• Reduce the frequency appropriately from 3-6 a.m.

Frequently Asked Questions QA

Q: What should I do if my proxy IP is not working?
A: Choose a service that supports automatic switching, like ipipgo's dynamic IP package with failover by default.

Q: What should I do if I always feel that the agent is slow?
