I. Why is your data collection always intercepted?
Many people have encountered this kind of trouble when doing data collection: obviously the program is written in a very standardized way, but the target website always suddenly breaks the connection. This situation is often because your network behavior is recognized by the website as abnormal traffic. Imagine, the same device with a fixed IP address high-frequency access, just like wearing the same clothes to the mall a dozen times a day, the security guards do not stare at you is strange.
The traditional solution is to manually switch proxy IPs, but this leads to two problems:Untimely switchingEasily triggered bans.Unstable IP qualityImpact the collection efficiency. At this time, an intelligent IP rotation system is needed to realize the optimal scheduling of IP resources through automation.
II. Core design of an intelligent rotation system
Three elements need to be prepared before building the system:Stabilized IP Resource Pool,Intelligent Scheduling Algorithm,Anomaly Detection MechanismThe following is a list of the most popular residential proxies available in the world. Here we recommend using ipipgo's residential proxy service, which covers real home network environments in more than 240 countries and regions around the world, with 90 million+ residential IPs forming a natural protective barrier.
assemblies | Functional Description |
---|---|
IP resource pool | A mix of dynamic/static IPs is recommended, with dynamic IPs used for high-frequency acquisition and static IPs handling tasks that require session maintenance |
scheduling module | Automatically select the optimal geographic node based on the response speed of the target website |
Detection Module | Real-time monitoring of the HTTP status code, found that the ban immediately switch |
III. Building a rotation system by hand
Demonstrate basic framework building with Python as an example:
Initializing the ipipgo connection pool
from ipipgo import ProxyPool
pool = ProxyPool(auth_key='your_api_key')
Smart scheduling function
def get_smart_proxy():
current_ip = pool.get(
region='auto', protocol='https', current_ip = pool.get(
protocol='https', sticky_session=60
sticky_session=60 Set when a session needs to be maintained.
)
return current_ip
Exception autoswitching
try.
response = requests.get(url, proxies=get_smart_proxy())
except ConnectionError: pool.ban(current_ip)
pool.ban(current_ip) Marks the IP as invalid.
get_smart_proxy()
Here's the key point.Setting a reasonable switching threshold: No more than 30 consecutive requests for a single IP, switching 5-8 geographic nodes per hour. ipipgo supports IP selection by ASN and city granularity, which is especially suitable for scenarios that require precise localization.
IV. Practical skills to enhance the success rate
1. Fingerprint Camouflage: work with ipipgo's high anonymity proxies to randomly switch the User-Agent and Accept-Language fields in the request header
2. flow metronome: Incorporate random delays (0.5-3 seconds) into the scheduling algorithm to simulate real-life operation intervals
3. Multi-protocol mixing: Use SOCKS5 protocol for strict anti-crawling websites and HTTP protocol for ordinary websites, fully utilizing ipipgo's all-protocol support feature.
V. Frequently asked questions
Q: How to detect whether IP is blocked by the target website?
A: Observe three signals: ① 403 status code appears continuously ② Response content contains CAPTCHA ③ Request timeout rate suddenly rises. ipipgo provides IP health detection interface to exclude risky IPs in advance.
Q: How to use dynamic IP and static IP together?
A: It is recommended that 7:3 ratio, dynamic IP for data capture, static IP to deal with the need to log in the state of the operation. ipipgo supports two types of IP instant switching, no additional configuration.
Q: What about slow transnational acquisition?
A: Enable the smart routing function in ipipgo console, the system will automatically select to the node with the lowest latency of the target server. The actual test can reduce the network delay of 40% or more.
