BeautifulSoup Fetching Text: Proxy IP to Improve Web Parsing Efficiency

Teach you to use proxy IP to the crawler "renewal".

Brothers engaged in crawling should have encountered such a scene: the code is clearly no problem, but suddenly stuck, and then later directly to you to report an error. At this time, eighty percent of the anti-climbing mechanism by the site stared at, like playing the game was detected by the system to open hung like. This time it is the turn of the proxy IP when the "resurrection armor".

Why does your crawler need a "stand-in"?

Many websites have installed "face recognition system", the same IP frequent visits will be pulled black. As if you go to the supermarket to try to eat, even take a dozen times the same type of cupcake, the clerk absolutely to roll their eyes. Proxy IP is to help you change the vest of the tool, each visit to change the identity, so that the site thinks it is a different user in the operation.

Here's a focus on ipipgo's one-of-a-kind:

- Dynamic IP pool of over 2 million+（"Large enough to be less likely to be compromised.)
- Minimum 5 seconds between automatic switching intervals(Much faster than manual changeover)
- Success rate guarantee of 98% or more（"Don't worry about disconnecting and reconnecting.)

Fitting BeautifulSoup with a cloak of invisibility

Let's start with a basic template and teach you to spice it up later:

import requests
from bs4 import BeautifulSoup

def basic_crawler(url): response = requests.
    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')
     Write your parsing logic here...

This bare-bones version of the code won't run for long before it kneels, let's use ipipgo's proxy service to transform it:

import requests
from bs4 import BeautifulSoup

PROXY_API = "http://ipipgo.com/api/getproxy?type=http" Remember to change it to your own account.

def smart_crawler(url):
    proxies = {
        "http": requests.get(PROXY_API).text, "https": requests.get(PROXY_API).text
        "https": requests.get(PROXY_API).text
    }
    try.
        response = requests.get(url, proxies=proxies, timeout=10)
        soup = BeautifulSoup(response.text, 'html.parser')
         The parsing logic goes here...
        return True
    except Exception as e.
        print(f "Falling off the wagon: {e}")
        return False

A practical guide to avoiding the pit

Here are a few points where older drivers tend to roll over:

Frequently Asked Questions First Aid Kit

Q: What should I do if I use a proxy and still get blocked?
A: Check if the cookie is not cleaned up, or the request header characteristics are too obvious. ipipgo background has the use of tutorials to teach you how to disguise as a real person to operate.

Q: Is it normal for proxy IP to affect the speed?
A: A good proxy should be like ipipgo so that the delay is controlled within 200ms, if more than 1 second it is recommended to change nodes.

Q: How do I verify if the agent is in effect?
A: Add a print(requests.get("http://ipipgo.com/checkip").text) in the code to see if the output IP has changed.

Upgrade your reptile gear

Lastly, I would like to give an advanced suggestion: put ipipgo's API into the crawler framework, and set up automatic retry + automatic IP replacement, so that even if you encounter the anti-climbing world of the "exterminator", your crawler can be as flexible as the Ant-Man shuttle.

If you're still using a single IP to harden your brother, hurry up and go to the ipipgo website to get a trial package. Now newcomers register to send 5G traffic, enough for you to test small and medium-sized projects. Remember, the programmer who can use tools and the programmer who can only write code, the efficiency can be ten streets away.
