python anti-reverse crawl proxy: Requests library IP proxy tips

Crawlers without proxies these days? You'll be blackballed in minutes!

Do crawl friends understand, now the site's anti-climbing mechanism than the neighborhood gates are more strict. Yesterday also ran a good script, today you will give you a429 Too Many RequestsWarning. Not having a pool of reliable agents on hand at this point is about as desperate as playing a game without a blood pack.

Take the requests library as a chestnut, many people think that adding a User-Agent will be able to muddle through. In fact, now the site has learned to check the account - the same IP frequent visits, directly blocked you no negotiation. This is the time to use ouripipgo proxy service, 90 million + residential IPs around the world change at will, faster than a Szechuan Opera face change.

The right way to open a proxy IP

First, you need to understand how to choose the type of agent (knock on wood):

Here's the kicker! When using ipipgo's dynamic residential IP, remember to put thesession hold timeThe settings are reasonable. Don't follow the example of some rash people who change IPs every time they request, which in turn tends to trigger anomaly detection.

Hands on vests for requests.

On the dry code, pay attention to the comments:

import requests
from itertools import cycle

 Here we use the proxy interface provided by ipipgo_proxies
def get_ipipgo_proxies(): [ return [
    return [
        "http://user:pass@gateway.ipipgo.com:30001",
        "http://user:pass@gateway.ipipgo.com:30002", ...
         ... More Proxy Nodes
    ]

proxy_pool = cycle(get_ipgo_proxies())

for _ in range(10):
    current_proxy = next(proxy_pool)
    try: current_proxy = next(proxy_pool)
        response = requests.get(
            
            proxies={'http': current_proxy, 'https': current_proxy}, timeout=10
            timeout=10
        )
        print(response.status_code)
    except Exception as e.
        print(f "Failed with {current_proxy}: {str(e)}")
         The logic for automatically rejecting failed proxies suggests the addition of the

Be careful to putuser:passReplace it with the authentication information you applied for on the ipipgo platform. It is recommended to use theirIntelligent Routing Function, automatically selecting the node with the lowest latency is much more reliable than manual polling.

A guide to avoiding the pit (blood and tears)

1. SSL Certificate ValidationShould I turn it off? We recommend leaving it on! ipipgo's proxy comes with a legit certificate, so don't follow those wild-ass tutorials on the internet and turn it off blindly!

2. EncounterConnection resetDon't panic, 80% of the time the site sends RST packets. This is the time to change ipipgo'sLong-lasting static IPIt is more robust than dynamic IP

3. Slow speed is not necessarily the fault of the proxy, check whether it ismultiplexed connectionDidn't do a good job. requests.Session() is used and saves a lot of handshaking time

QA time (a must for the little guy)

Q: Why is it still blocked after using a proxy?
A: Check to see if there is a band in the request headerProxy-ConnectionSuch identity-revealing fields, ipipgo's advanced mode automatically cleans up these features

Q: Do I need to maintain my own IP pool?
A: Not at all if you use ipipgo! They'reIntelligent Switching SystemMore reliable than manual maintenance, it also automatically matches local residential IPs based on the location of the target site

Q: What about HTTPS sites?
A: directly in the proxies parameters to configure https proxy on the line, ipipgo full protocol support this point is really worry-free, not like some platforms also have to toss the certificate!

As a final word of caution, don't just look at price when choosing a proxy service. A service like ipipgo canAccurately assign city-level egress IPsThe service can save your life at the critical moment. Last time, a buddy collected public data from the government, because the IP location is not allowed to be intercepted, replaced with our municipal static IP immediately smooth...
