Proxy crawling: the latest proxy IP technology to achieve efficient data collection

When Crawlers Meet Fire Prevention? Try this proxy IP combo

The old iron engaged in data collection should understand that now the website anti-climbing mechanism is more and more ruthless. Yesterday can still use the crawler, today may be blocked IP. If you don't have someProxy IP's best workThe first thing you need to do is to get the data from your computer and then you will have to stop working. We do not organize those false today, directly on the dry goods to say how to use ipipgo's proxy service to play around with data collection.

Dynamic IP pools are the way to go

Don't use those free proxies anymore! Not only is it slow as a snail, but security is a concern. ipipgo'sDynamic massive IP poolThere are three major killers:

1. automatically switch IP address every 5 seconds
2. Supports HTTP/HTTPS/SOCKS5 protocols
3. 200+ city nodes in China to choose at will

Tested with this configuration, continuous collection of an e-commerce platform for 3 hours without being intercepted. The key is to set upIP Switching PolicyIt is recommended that the frequency be adjusted according to the strength of the backcrawl of the target site.

New Ideas for CAPTCHA Cracking

Don't panic when it comes to CAPTCHAs, try this combination of solutions:

The point is toDifferent IP corresponds to different cracking programDon't use the same IP over and over again for trial and error.

There's something to be said for concurrency control

A lot of people think it's faster to have multiple threads on, but it ends up blocking IPs in seconds. suggest trying this onegradient concurrency method::

import requests
from ipipgo import ProxyPool

proxy = ProxyPool(api_key="your_key")
session = requests.Session()

 Automatically manage proxy IP request methods
def smart_get(url).
    session.proxies = proxy.get_random()
    response = session.get(url)
    if response.status_code == 403.
        proxy.report_failure() mark IP as failed
        return smart_get(url)
    return response

The essence of this code isAutomatic rejection of invalid IPsThe API of ipipgo provides real-time feedback on IP health status, which is much more hassle-free than manual maintenance.

Practical QA face-to-face

Q: What should I do if I always get my IP blocked?
A: Check three things: 1. whether the IP purity is high enough 2. whether the request header is randomly replaced 3. whether the access frequency is regular. Use ipipgo's enterprise-level proxy pool, which comes with aRequest for fingerprint disguiseFeature, pro-tested to effectively reduce the ban rate.

Q: Can't get the acquisition speed up?
A: Don't just focus on bandwidth, try ipipgo'sIntelligent RoutingFunction. Automatically selects the node with the lowest latency, which works better than mindlessly stacking threads. A customer used this feature and data throughput directly tripled.

Q: What if I need a specific city IP?
A: In the ipipgo console select thegeographic positioningFunctions that support refinement to the municipal level administrative districts. Especially useful when doing localized data collection, for example, to capture the information of house price in a city.

Don't Let Your Crawler Run Naked

At the end of the day, proxy IPs are like crawlers dressed up in acloak of invisibilityipipgo recently upgradedhybrid proxy modelAfter a customer doing public opinion monitoring used it, the collection success rate directly soared from 47% to 92%, and the effect was instantly visible.

Finally remind the novice attention: do not use proxy IP in the user authentication session! Login operation is recommended to use a fixed IP, and then switch the proxy when collecting data, so as to ensure account security, but also to improve the collection efficiency. More tart operation can go to ipipgo official website to see theirScenario-based solutions, various oddball anti-climbing scenarios have corresponding strategies.
