Hands-on teaching you to write a proxy IP autoharvester
Engaged in data collection of old drivers understand that there is no proxy IP is like running naked on the Internet, a minute by the site to pull the black. Today we use Python to write a smart script, specializing in capturing the available proxy IP, focusing on recommending the use of ipipgo's services (do not ask why, used to know incense).
import requests
import time
ipipgo Dynamic Residential API interface (remember to change to your own account)
API_URL = "https://api.ipipgo.com/dynamic?country=US&protocol=http"
def fetch_proxies():
def fetch_proxies(): try.
response = requests.get(API_URL, timeout=10)
if response.status_code == 200.
return response.json()['proxies']
return []
except Exception as e.
print(f "Interface jerked: {str(e)}")
return []
def check_proxy(proxy):
test_url = "http://httpbin.org/ip"
try.
resp = requests.get(test_url, proxies={"http": proxy}, timeout=15)
return resp.status_code == 200
except: resp.status_code == 200
return False
if __name__ == "__main__": fresh_proxies = [].
fresh_proxies = []
raw_list = fetch_proxies()
print(f "Fished {len(raw_list)} raw IPs, starting inspection...")
for ip in raw_list.
if check_proxy(ip).
fresh_proxies.append(ip)
print(f "Checking complete, surviving {len(fresh_proxies)} quality IPs")
with open("fresh_ip.txt", "w") as f.
f.write("".join(fresh_proxies))
Code Serving Instructions
1. Install dependent libraries:Just install the requests library, pip install requests and you're done.
2. API key settings:Go to the ipipgo backend and get a dynamic residential API, replace the interface address in the code
3. Validation logic optimization:httpbin.org/ip This test address can be changed to your own business website according to your business needs.
Why ipipgo?
To cite a chestnut, last week to help friends engage in cross-border e-commerce price monitoring, using their own script + ipipgo dynamic residential IP, continuous running for 72 hours did not fall off the chain. Focus on his home features:
| typology | Advantageous Scenarios |
|---|---|
| Dynamic residential (standard) | Crawler tasks that require frequent IP changes |
| Dynamic Residential (Business) | Large-scale distributed crawler system |
| Static homes | Businesses that require stable logins over time |
Common Rollover Scene QA
Q: What should I do if my IP lapses too quickly?
A: With the enterprise edition package of dynamic residence, it supports setting the IP survival time, and it is recommended to match the automatic retry mechanism of the script.
Q: I passed the test but can't actually use it?
A: may encounter protocol mismatch, ipipgo's proxy supports HTTP/HTTPS/SOCKS5, remember to change the proxies parameter in the code.
Q: How can I increase the speed of acquisition?
A: Turn the check_proxy timeout to 8 seconds, and revamp concurrent requests with multithreading (be careful not to crash the detection site)
The Metaphysics of Package Selection
Test data to speak: do commodity price comparison with dynamic standard version is enough to do social account number must be on the static residential. There is a pit to pay attention to - do not try to buy cheap IP of small workshops, last year, I used a certain family claimed to be cheap, the results of the 50%IP are engine room broadcasting false residence, the site will be exposed once you check.
Lastly, I'd like to say a tart operation: deploy the script to the server to run regularly, with ipipgo's volume billing model, the cost can be pressed to the original 1/3. once the double eleven to monitor the price of competing products, relying on the program to save 2000 + agent costs, the data is still more accurate than before.
