Crawler Proxy: Crawler Proxy IP settings and efficient collection tutorials

Handy Crawler Proxy Settings

engaged in crawlers know, with proxy IP is like wearing a vest - both to protect themselves, but also unimpeded. Today we will nag how to use ipipgo family proxy, so that data collection is as stable as the old dog.

First straighten out the proxy type:dynamic IPsuitable for high-frequency acquisition (e.g., e-commerce comparison).static IPSuitable for scenarios that require a fixed identity (such as account registration). Don't be in a hurry, take a test IP to test the water first and make sure it works before you batch it up.

import requests

 Example of proxy setup (using ipipgo as an example)
proxy = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:端口',
    'https': 'https://用户名:密码@gateway.ipipgo.com:端口'
}

response = requests.get('destination URL', proxies=proxy, timeout=10)

The tawdry operation that doubles collection efficiency

I've seen too many people use proxy IPs as tractors, so I'd like to share three tried-and-true speed boosting tips:

1. Connection Pool Management: Don't re-establish connection for each request, reuse existing channels to save 30% time!
2. Intelligent switching strategy: Response more than 2 seconds automatically change IP, do not stick to a channel!
3. Geographic Precision Placement: Use ipipgo's 200 country resources, and use the IP of the target website wherever it is located!

How to choose an ipipgo proxy package

Speaking from personal experience, it is recommended to do search engine crawlers using theTK LineThe collection success rate can be more than 98%. encountered anti-climbing ruthless website, directly on theirDedicated Static IP, pro-tested to be much more stable than a shared IP.

Guidelines on demining of common problems

Q: What should I do if my proxy IP is always blocked?
A: three key points: 1. switching frequency is not too regular 2. with the UA random 3. priority with residential IP. ipipgo's dynamic residential pool is large enough, the automatic switching function can save a lot of things

Q: How can I tell that the proxy is in effect?
A: Start with https://ip.ipipgo.com/checkip查IP归属地 and then run a test script to see the status code. It is recommended to do this check on every startup

Q: Overseas website collection is particularly slow?
A: Try ipipgo's cross-border line, go the operator direct connection channel. Before there is a cross-border e-commerce friends with this, the collection speed directly three times faster!

lit. experience of avoiding a pitfall (idiom); experience in avoiding pitfalls

Seen too many people fall into these pits:
1. Use free proxies for cheap, but the data is leaked.
2. no timeout retry setting, one lag and all hell breaks loose
3. Forgot to turn off the proxy debugging local code, and could not find the bug.
These problems can be avoided by using a proxy from a regular service provider (like ipipgo). Their API extraction is super easy and comes with a usage alert, so it's solid to use.

Finally said a cold knowledge: collection frequency should not be stuck on the other site's threshold settings, it is best to leave 20% margin. Don't be hard on the CAPTCHA when you come across it, and it is often more efficient to change the IP and retry. Use a good proxy IP, data collection is really not as difficult as imagined.
