Crawler Proxy IP: Stable and efficient dedicated proxy IP service for data collection

What to do when a crawler encounters an anti-climb? Try this steady-as-an-old-dog maneuver

Do data collection of the old iron should understand, now the site's anti-climbing mechanism is more and more ruthless. The front foot just grabbed two pages of data, after the foot of the IP was sealed to death. At this time we have to rely on proxy IP to continue, especially for long-term data monitoring, no reliable proxy pool, minutes by the site blacklist.

The biggest pitfall of ordinary agents isprecariousrespond in singingslowThe first thing you need to do is to get your hands on a free agent. Used to know, the free agent ten in eight can not be used, the remaining two than the snail is still slow. This time we have to find like ipipgo such professional service providers, their home room node quality is really top, the actual test run for three days in a row did not fall off the line.

Three tips to teach you to pick the right proxy IP service provider

Don't just look at the price when choosing a proxy service provider, focus on these hard indicators:

A special shout out to ipipgo'sIntelligent SwitchingThe function is to automatically detect whether the IP is banned or not, and cut the new node in a second if there is any problem. Before using other family also have to write their own detection script, now directly save the trouble.

Hands-on guide to configure proxy IP

Taking the Python crawler as an example, using the requests library to interface with ipipgo's API can be done in three steps:

import requests

 API interface from ipipgo
proxy_api = "http://api.ipipgo.com/get?key=你的密钥"

def get_proxy():
    resp = requests.get(proxy_api)
    return {'http': f'http://{resp.text}', 'https': f'http://{resp.text}'}

 Initiate a request with a proxy
response = requests.get('destination URL', proxies=get_proxy(), timeout=10)
print(response.status_code)

Remember to set the timeout to a shorter time, no more than 15 seconds. If you encounter a connection timeout, just retry with a new IP, don't hang yourself on a tree.

Five Pitfalls Older Drivers Can't Avoid

Pit 1: Proxy IP frequently fails
With ipipgo.dynamic concurrency modelIf you want to change the IP address of your computer, you have to change the IP address of your computer every time you request it, and you can reduce the probability of being banned by yourself.

Pit #2: Sites require login to crawl
Remember to use it with a cookie pool, don't tie the cookie to the IP, ipipgo supports session holding

Pit 3: Sudden surge of CAPTCHA
Set a reasonable request interval, ipipgo background can be customized request frequency, it is recommended to set at 3-5 seconds / times

A must-see QA session for the little guy

Q: What should I do if my proxy IP is slow?
A: Prefer ipipgo's BGP line, measured faster than ordinary telecom lines 40%

Q: How do I test if the agent is valid?
A: Use this script for a quick check (see the configuration section for code examples), or directly use the real-time monitoring panel in the ipipgo backend

Q: What should I do if I encounter Cloudflare protection?
A: on ipipgo'sHighly anonymous residential agentsThe browser is accessed under the guise of a real user's browser

Finally, to be honest, the proxy IP thing is worth every penny. Previously, I bought a 9.9 monthly service for a cheap price, but the result was that I lost more money due to the delayed progress of the project. Now long-term use ipipgo annual package, combined down to less than a cup of milk tea money every day, the key is to save ah. Their technical support response is quite fast, the last time I encountered a strange anti-climbing strategy, customer service directly to help adjust the solution, the service is really worth the price.
