Last week a client who does opinion monitoring switched to ipipgo'sdynamic rotation agentAfter that, the single-day collection volume skyrocketed from 30,000 to 200,000, and the key data integrity rate also increased by 30%.

Practical operation guide (hands-on teaching)

Take the Python crawler as an example of the correct posture with proxy IPs:

import requests
from itertools import cycle

proxies = ipipgo.get_proxy_pool() get dynamic IP pools
proxy_cycle = cycle(proxies)

for page in range(1,100): current_proxy = next(proxy_cycle)
    current_proxy = next(proxy_cycle)
    current_proxy = next(proxy_cycle)
        response = requests.get(url, proxies={'http': current_proxy}, timeout=8)
         Processing data logic...
    except.
        ipipgo.report_failure(current_proxy) Automatically rejects failed IPs

Be careful to set thetimeout retry mechanismDon't be a hard-ass when it comes to CAPTCHA. We recommend using ipipgo.Intelligent switching modeThe system will automatically cut to the premium IP segment.
