Python request library: Python request + proxy IP configuration

Hands-on with the Python request library to hang a proxy IP

The old iron engaged in crawlers must have encountered this situation: just run a few minutes script, the target site will block your IP! In this case, you need to rely on proxy IP to save the day. Today we take Python's most commonly used requests library to teach you how to use ipipgo's proxy service to break through the restrictions.

Why do you have to use a proxy IP?

For example, your neighborhood guards hold a grudge, and every time they see you, they stop you from entering. At this time you change a vest (proxy IP), the gatekeeper will not recognize. Website anti-climbing mechanism is also the same reasoning, frequent visits with the same IP, people will certainly want to pull the black you.

With ipipgo's dynamic IP pool, it's the equivalent of getting a new vest every time you visit. Their family specializes in this, IP survival time control just right, unlike some free proxies with a couple of lapses.

Three Steps to Configuring Agents

Let's start with the most basic configuration method, taking the http proxy as an example:

import requests

proxies = {
    'http': 'http://用户名:密码@ipipgo proxies:port',
    'https': 'http://用户名:密码@ipipgo proxy:port'
}

response = requests.get('destination URL', proxies=proxies)

Notice a pitfall here! A lot of newbies miss it.https proxy configurationThe result is that the https site is still accessed with the local IP. Remember to match both protocols, don't be lazy.

Essential Skills for Advanced Players

If you need to rotate multiple IPs, it's recommended to use a session object. This will automatically change the IP for each request, saving you from having to do it manually:

from requests import Session
from itertools import cycle

ip_list = [
    'ipipgo proxy address 1',
    'ipipgo proxy address 2',
    'ipipgo proxy 3'
]
proxy_pool = cycle(ip_list)

with Session() as s.
    for _ in range(10): proxy = next(proxy_pool)
        proxy = next(proxy_pool)
        s.proxies = {'http': proxy, 'https': proxy}
        s.get('destination URL') 

This method is especially good for people who needlong time runningThe crawler task. ipipgo's API supports dynamic acquisition of IP lists, and it is recommended to directly interface with their interface to ensure IP freshness.

Guide to avoiding the pit (QA session)

Q: What should I do if the agent is assigned but not in effect?
A: Check the proxy format first, especiallyUser name and passwordDon't write it backwards. Test the proxy connectivity with the curl command:
curl -x http://代理地址 -U username:password https://httpbin.org/ip

Q: Suddenly all requests time out?
A: Eighty percent of the IP is blocked by the target site. This time to changeHigh Stash Agents, ipipgo's exclusive IP package is a solid performer in this regard.

Q: How can I tell if an agent is highly anonymous?
A: Visit httpbin.org/ip to see if the returned header has aX-Forwarded-Forfield. True High Stash Proxy does not leak the client's real IP.

Best Practices Cheat Sheet

A few final practical suggestions:

• Don't write dead proxy addresses in code, use environment variables to store sensitive information
• reasonabletimeout(3-5 seconds recommended)
• With ipipgo'svolumetric billingPackages. Use as much as you want.
• Remember important tasks.IP whitelistingverification function

Don't panic when you encounter proxy-related problems, go to ipipgo's documentation center to look up cases. Their tech support responds quite quickly, and last time I raised a work order in the middle of the night, it was actually returned in 10 minutes...
