When the crawler meets the anti-climbing how to do? Try this proxy IP trick
Recently, a lot of friends complained to me that using BeautifulSoup to capture data was always blocked by the website IP! Last year to do e-commerce price monitoring, for three consecutive days was blocked more than a dozen IP, so angry that I almost dropped the keyboard. Later found a trick -Proxy IP RotationToday, we'll show you how to play with proxy IPs and BeautifulSoup by hand.
Why do I have to use a proxy IP?
To give a real example: one day at three o'clock in the morning, I was using a crawler to catch the new product data of a clothing website. Suddenly, the script got stuck, and the return code was 403 - the IP was blocked again! At this time if there is a proxy IP, directly change the IP can continue to work. It's like playing a game to open a small number, the big number was blocked immediately change the small number, save time and effort.
| take | No need for an agent. | using a proxy |
|---|---|---|
| High Frequency Visits | Blocked in 10 minutes. | Continuous operation for 8 hours |
| Data collection volume | Average of 500 per day | 20,000 entries per day |
| maintenance cost | Daily IP Change | Configure once for half a year |
Hands-on integration tutorial
Here use ipipgo's proxy service to demonstrate, one good thing about their house is that you don't need to manually change the IP every time, it supports automatic rotation. First install the necessary libraries:
pip install requests beautifulsoup4
Example of live code (remember to replace it with your own account information):
import requests
from bs4 import BeautifulSoup
Here we use the API interface provided by ipipgo
proxy_api = "http://ipipgo.com/api/getproxy?key=你的密钥"
def get_proxy():
resp = requests.get(proxy_api)
return {'http': f'http://{resp.text}', 'https': f'http://{resp.text}'}
url = "target site"
headers = {'User-Agent': 'Mozilla/5.0'}
try.
The point is in this line! Automatically change the IP address for each request
response = requests.get(url, headers=headers, proxies=get_proxy())
soup = BeautifulSoup(response.text, 'html.parser')
Write your parsing logic here...
except Exception as e.
print(f "Error: {e}")
A Guide to Avoiding the Pit (Blood and Tears)
I stepped into these potholes when I first started using proxy IPs:
1. did not set the timeout parameter → program crash → add timeout = 10
2. Forgot to catch exceptions → program crashes → wrap with try.... . except package
3. use transparent proxy → still blocked → change to high stash proxy
Especially recommend ipipgo'sDynamic Residential AgentsThe IP pool is updated quickly and has an automatic validation function. Their IP pool is updated quickly, but also with automatic verification, invalid IP will be automatically filtered.
Frequently Asked Questions QA
Q: What should I do if my proxy IP is slow?
A: choose the node close to the target server, ipipgo support filtering by region, choose the fastest proxy node in the same city
Q: Do free proxies work?
A: Newbies can test the waters, but serious projects must not! Previously tested, the availability of free proxies less than 20%, delaying the matter
Q: How can I tell if a proxy is in effect?
A: Add a print statement to the code to type out the IP used each time. Or visit http://ip.ipipgo.com/checkip to see the IP returned
Upgrade Play Tips
Recently, I found a tasty operation: using proxy IPs in combination with random UA. For example, like this:
import fake_useragent
ua = fake_useragent.UserAgent().random
headers = {'User-Agent': ua}
With ipipgo's pay-per-use package, it is especially cost-effective to do small and medium-sized projects. Remember to set the number of concurrency is not too high, newcomers are recommended to control within 5 threads.
One final word of caution: use a proxy IP toCompliance with website rulesDon't hang people's servers. Use the tools wisely, in order to obtain data stably for a long time. Encounter technical problems can directly consult ipipgo technical customer service, reply speed is quite fast, the last two o'clock in the morning to ask questions actually seconds back...
