Baidu domestic website crawler agent pool: Baidu crawler dedicated agent pool building program

Why do Baidu crawlers need a dedicated proxy pool?

Do website data crawl friends understand, Baidu this platform of anti-climbing mechanism upgraded particularly fast. For example, last week can still use the IP address, this week may be pulled black. At this time, if you use a fixed IP hard, you can receive a CAPTCHA bombing in minutes.

To cite a real case: last year, there is a small team of e-commerce price comparison, three consecutive days were intercepted more than 200 requests, and finally led directly to the server IP was Baidu black. They later changed to useDynamic residential agent poolThe crawl success rate is directly mentioned above 92%.

The Three Pitfalls of Building Your Own Proxy Pool

1. IP quality varies: Some free proxies look like they work, but the actual latency is ridiculously high, with 9 out of 10 requests timing out!
2. Maintenance costs are too high: It takes two to three hours a day to check for invalid IPs, it's like whack-a-mole.
3. protocol incompatibilityBaidu is now particularly strict detection of socks4 protocol, a lot of proxies simply can not pass the verification!

Build a stable proxy pool in three steps with ipipgo

 Sample code to get proxy IP (Python)
import requests

def get_proxy():
    api_url = "https://api.ipipgo.com/dynamic?type=standard"
    resp = requests.get(api_url).json()
    return f "http://{resp['ip']}:{resp['port']}"

Specific operational procedures:
1. In the ipipgo back office selectDynamic Residential (Enterprise Edition)product or service package (e.g. for a cell phone subscription)
2. Setting the frequency of automatic refreshing (it is recommended to change the batch of IPs every 5 minutes)
3. Add an exception retry mechanism to the crawler code.
