BeautifulSoup Crawl Website: BeautifulSoup Proxy Crawl

Crawler always be blocked IP, try to use the proxy ip to BeautifulSoup layer of protection.

Brothers engaged in data capture should understand that the use of BeautifulSoup parsing web page content, although smooth, but direct hard target site is easy to eat the door. Especially now that many websites have installedIntelligent Risk Control SystemIf you have a proxy ip, you can use it as a stand-in for a proxy ip, especially one like ipipgo. At this time you need a proxy ip to be your stand-in actor, especially like ipipgo this kind of service provider specializing in high-quality proxy, can definitely let you go a lot less detours.

Hands on Vesting for Crawlers

First prepare a pool of proxy ip can be used, here directly take ipipgo HTTP proxy as a demonstration. Their proxy format looks like this:
123.123.123.123:8888:username:password

import requests
from bs4 import BeautifulSoup

proxies = {
    'http': 'http://username:password@123.123.123.123:8888',
    'https': 'http://username:password@123.123.123.123:8888'
}

response = requests.get('https://目标网站.com', proxies=proxies)
soup = BeautifulSoup(response.text, 'html.parser')
 Here's where you continue your parsing operations...

Be careful to putusernamerespond in singingpasswordChange it to the authentication information you got in the ipipgo backend. It is recommended to write the proxy configuration into a separate configuration file, so that you do not have to change the code all over the world when you want to change the ip.

Don't panic when encountering CAPTCHA, proxy ip has a good trick

Some sites find that abnormal access will pop up a CAPTCHA, which can be used with a proxy ip to do two things:

1. Retry request with different ip
2. Reduce the frequency of visits to a single ip

Give a real-world example:

import random
from time import sleep

ip_list = ipipgo.get_proxy_list() This calls ipipgo's API to get the latest ip pool.

for page in range(1, 100): current_proxy = random.choice(ip_proxy_list)
    current_proxy = random.choice(ip_list)
    try: current_proxy = random.choice(ip_list)
        response = requests.get(url, proxies=current_proxy)
        if 'CAPTCHA' in response.text: print(f "IP {current_proxy}")
            print(f "IP {current_proxy} is restricted, automatically switch to the next one")
            continue
         Normal parsing flow...
    except Exception as e: print(f "IP {current_proxy} is restricted.
        print(f "Error: {str(e)}")
    sleep(random.uniform(1,3)) Randomly waiting for blocking to occur

How to choose a quality proxy service provider?

Reptile Party FAQ First Aid Kit

Q: What should I do if the proxy IP suddenly fails to connect?
A: First check the proxy format is not correct, especially the port number and password there is no error. ipipgo background real-time availability monitoring, found that abnormal IP can be directly in the user center one-click refresh.

Q: How do I test the actual speed of the proxy?
A: Use this script to measure latency:

import datetime

start = datetime.datetime.now()
requests.get('http://测试网站', proxies=proxies)
cost = (datetime.datetime.now() - start).total_seconds()
print(f "Current proxy response took: {cost:.2f} seconds")

Q: What if I need to manage a large number of agents at the same time?
A: ipipgo provides API interface can be directly integrated into the crawler system, support for filtering IP by region and operator, and can also set the frequency of automatic replacement.

Say something from the heart.

Just started using proxy ip that moment I also stepped on a lot of pitfalls, until the use of ipipgo realized that a good proxy can really make the crawler twice as efficient. TheirDynamic Residential AgentsParticularly suitable for the need to run long-term data projects, with BeautifulSoup to do content capture basically did not miss a hand. Recently look at the official website to do new user activities, the first single can play 7% off, there is a need for brothers can go to woolgathering try.
