http crawler proxy: Python crawler configuration high-quality HTTP proxy IP solutions

Why are crawlers always blocked? Proxy IP is a life preserver

Recently a lot of data crawling buddies find me to complain, just write a good crawler script did not run for two days on the blocked IP. this thing is frankly the site anti-climbing mechanism in the demon, the same IP high frequency access to be sure to be stared at. This time you have to learnchange of armor--Rolling requests with proxy IPs to make the target site think it's being accessed by different users.

There are all kinds of proxy services on the market, but there are really not many reliable ones. Some sellers' IPs have long been blacklisted, and they die faster with this kind. Here we must mentionipipgoThe home's dynamic residential IPs, which are real home broadband outlets, are more than a notch stronger in terms of camouflage than server room IPs.

Proxy Configuration in Three Minutes

Taking Python's requests library as an example, proxy configuration is simpler than cooking instant noodles. The key is to get a reliable IP pool, here to teach you to use ipipgo's API to get available IP in real time:

import requests

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

def get_proxy():
    res = requests.get(proxy_api)
    return {'http': f'http://{res.text}', 'https': f'http://{res.text}'}

url = "https://目标网站.com"
response = requests.get(url, proxies=get_proxy())

Be careful to putkeysChange to your own account, don't be silly to copy this code directly. ipipgo's background can also set the IP survival time, it is recommended to adjust according to the business needs, don't let the IP expire prematurely.

Choose the right package so as not to spend a lot of money.

A pitfall that many newbies tend to step into isWrong type of package, here is a list of solid suggestions:

In particular.TK LineThis hidden function, do cross-border e-commerce friends can focus on. Previously there is a do independent station brother with this program, API request success rate directly from 60% soared to 98%.

A must-see guide to avoiding the pitfalls for beginners

Q: What should I do if I use a proxy IP and it becomes slow?
A: 80% of the IP pool quality is not good, it is recommended to switch in the ipipgo backgroundCarrier lines. Their cross-border line is a real flavor, especially for scenarios that require overseas IPs

Q: How do I check if the proxy is in effect?
A: Visit the address http://ip.ipipgo.com/checkip, it can show the current use of the export IP. Remember to add your own server IP in the whitelist, do not be blocked by your own firewall!

It's all for naught if you don't pay attention to these details

1. Don't be a fool and use only HTTP protocol, some sites detect the protocol type. ipipgo supports it.Socks5protocol, it's a matter of changing a parameter in the requests.
2. Each request randomly add 0.5-3 seconds delay, do not let the access rules by the site to feel through the
3. Regularly clear cookies, it is recommended to reset the session every 50 requests
4. Encountering the verification code do not hard just, the use of coding platform on, proxy IP is not a panacea!

One last piece of cold knowledge: ipipgo'sclient softwareBeing able to switch IPs automatically saves a lot of work than using APIs. Especially if you do browser automation, you can install a plugin to realize senseless IP rotation, which is personally tested to be much more stable than the hard-coded way.
