When Crawler Meets CAPTCHA? Try this hidden skill
Recently, a friend who does e-commerce complained to me that the crawler program he wrote is always recognized by the platform, and it doesn't move, but it pops up the CAPTCHA. I asked him:"You're using a local IP, right?"The moment he nodded his head I knew what the problem was. Nowadays, many websites are particularly sensitive to high-frequency access to the IP, and this time we need to use our secret weapon - short SOCKS5 proxy.
Why short-period agents are the fighters of temps
Ordinary proxies are like long-term workers, an IP used for a long time is easy to be targeted. Short-term proxies are more like teams of temporary workers, automatically changing people (IP addresses) every 10-30 minutes. This kind ofDynamic rotation mechanismEspecially suitable for scenarios that require continuous operation:
| application scenario | Recommended Agent Type |
|---|---|
| E-commerce price comparison monitoring | 5-minute short-acting |
| Social Platform Operations | 15-minute short-acting |
| data acquisition | 30-minute short-acting |
Hands-on with ipipgo's S5 Proxy
Here's an example of ipipgo's proxy service to teach you quick access. There is a feature of their proxy -ready-to-useNo complicated authentication process is required.
import requests
proxy = {
'http': 'socks5://账号:密码@gateway.ipipgo.com:20000',
'https': 'socks5://账号:密码@gateway.ipipgo.com:20000'
}
response = requests.get('destination URL', proxies=proxy, timeout=10)
print(response.text)
Notice in the code the20000 portsThis is the SOCKS5 dedicated channel for ipipgo. If you encounter connection problems, try switching the alternate ports 20001-20005.
I've stepped in every hole you could possibly encounter.
Question 1: What should I do if the agent suddenly fails to connect?
Don't panic yet, the short-lived proxy would have been replaced periodically. It is recommended to add a retry mechanism in the code, and reconnecting 3 times in 5 seconds interval can basically solve the problem.
Question 2: Is it normal to have fast and slow speeds?
It's like taking a cab and meeting different drivers. ipipgo's nodes are spread all over the country, and it's recommended to choose theco-provincial nodeCapable of boosting 301TP by 3T or more.
Why do you recommend ipipgo?
After using seven or eight agency services, I finally chose ipipgo mainly because of three real advantages:
- Automatic switching of export IPs per request, no need to manually change them
- be in favor ofpay per volumeYou can use as much as you want without wasting it.
- There is a specialized anomaly detection system that automatically filters failed nodes
They also recently came out with a new feature - theIP Quality ScoreThis is especially useful for projects that require stability.
Frequently Asked Questions First Aid Kit
Q: Can the short-acting agent be used to log in to my account?
A: Not recommended! Frequent IP changes may trigger the platform's security mechanisms, and long-lasting static IPs are recommended for operations such as registration/login.
Q: Will it conflict if I open more than one mission at the same time?
A: ipipgo's concurrent connection pool supports multi-threading, each thread will be automatically assigned a different IP, remember to control the frequency of requests on it.
Q: It was normal during the test, but the IP was blocked when it was officially running?
A: Check if the request header carries browser fingerprints, a combo of random UA + ipipgo proxy is recommended.
Finally, a piece of cold knowledge: some platforms detect IPsShelf lifeIf you're using a short-lived proxy, it's safer than a long-lived proxy. Next time you encounter anti-climbing do not rush to change the code, change the IP may be the darkness of the light.
