How can dynamic proxy IPs improve efficiency? Crawler Data Collection Optimization Solution

How can I play with dynamic proxy IPs to save more?

Engage in data collection is the biggest headache is to be blocked IP, this side just grabbed a few hundred pieces of data over there to give you a pinch. At this time we have to rely on dynamic proxy IP to continue, but many people use the dynamic proxy or overturned, the problem lies in the usage.

To give a chestnut, some brothers directly take the dynamic IP pool random change, the result is that every request to re-establish the connection, slow as a snail. Here is aGolden Rule: Keep the IP survival time within the business time-consuming range. For example, if you need 30 seconds for each collection, set the IP validity period to 40 seconds, so that you will not be blocked and do not need to change IP frequently.

import requests
from itertools import cycle

 Example of ipipgo dynamic proxy configuration
PROXY_POOL = [
    'http://user:pass@proxy1.ipipgo.net:3000',
    'http://user:pass@proxy2.ipipgo.net:3000'
]
proxy_cycle = cycle(PROXY_POOL)

 Automatically rotate proxies on request
def smart_request(url):
    for _ in range(3): fail and retry 3 times
        proxy = next(proxy_cycle)
        try.
            resp = requests.get(url, proxies={'http': proxy}, timeout=15)
            if resp.status_code == 200: return resp.
                return resp.text
        except: resp.status_code == 200: return resp.text
            continue
    return None

Three Top Tips to Double Crawler Efficiency

The third move is the toughest. It's calledTraffic camouflage.. Make the request intervals a real person operating mode:

• Page dwell time is randomly in the range of 3-8 seconds
• Random pause when scrolling pages
• Automatic reduction of request frequency during the early morning hours

ipipgo real-world configuration program

According to the optimization cases we have done for our customers, we recommend this golden parameter combination:

Here's the kicker.hybrid modelThe usage of: use static IP to do login to keep the session, dynamic IP is responsible for the specific collection action. This will not trigger the CAPTCHA, but also ensure the collection speed.
