Why is your crawler always blocked? You may be missing this tool
Many newbies, when writing crawlers in Python, often encounter situations where the access frequency is too high and is restricted. Obviously, a random delay has been set, but it is still recognized by the website as a crawler program. This is the time to pay attention toAre your web requests exposing machine features-- Regular proxy IPs are like just wearing a mask, while high stash proxies are the real cloak of invisibility.
Three minutes to understand how high stash agents work
The High Anonymity Proxy will be completelyReplace your original IP and device information. Imagine you are using a friend's address to receive a courier when you are shopping online, all the web server sees is the proxy server's information and won't find the real crawler program behind it.
Agent Type | Degree of feature exposure |
---|---|
High Stash Agents | Completely hide client information |
General anonymous | Exposing the use of proxy behavior |
Transparent Agent | Completely expose the real IP |
Why residential IPs are the best partner for crawlers
Server room IPs are easily recognized as bulk access, while residential IPs come from real home network environments. For example, ipipgo'sResidential IP coverage in more than 240 countries and regions worldwideEach IP is a real home broadband address, which, together with the automatic IP replacement feature, can make your crawler requests look like regular users in different regions.
Python Hands-on Configuration Guide (with code)
Take the requests library as an example of a dynamic residential proxy using ipipgo:
import requests proxies = { 'http': 'http://用户名:密码@gateway.ipipgo.com:端口', 'https': 'http://用户名:密码@gateway.ipipgo.com:端口' } response = requests.get('destination URL', proxies=proxies, timeout=10)
Key Tip:
- Automatic IP change per request (dynamic proxy mode)
- Use with Randomized User-Agent
- Use of fixed IPs for critical requests (static residential proxies)
Avoid these potholes and increase your success rate by 90%
Ever had any of these problems?
- Just changed IP is recognized - may be shared IP is abused, suggest using ipipgo'sExclusive Residential IP
- HTTPS web certificate reporting errors - make sure the proxy supports the full protocol, especially websocket protocols
- Foreign website access timeout - select the target region local IP, such as climbing the United States website with ipipgo's U.S. residential IP
Frequently Asked Questions QA
Q: Do free proxies work?
A: Most of the free proxies are transparent proxies, which will not only be recognized, but also have the risk of data leakage. It is recommended to use high stash proxies from professional service providers such as ipipgo.
Q: Do I need to maintain my own IP pool?
A: No need, ipipgo provides automatic IP replacement service and supports API to get the latest available IP in real time, saving maintenance cost.
Q: What should I do if I encounter a website CAPTCHA?
A: Reasonably control the frequency of requests, together with the use of high stash residential IP. ipipgo has a long IP survival period, which is suitable for scenarios where sessions need to be maintained.
By reasonably configuring a high stash of residential proxies, you can effectively break through most of the anti-climbing mechanisms. It is recommended to choose a service provider like ipipgo that covers a wide range of areas and has high IP purity. The dynamic IP rotation mechanism and real residential IP resources they provide are the key to guaranteeing the stable operation of the crawler.
