The biggest headache in data collection.
Everyone engaged in AI model training old iron must have a deep experience, the most damaging thing is that the data is not enough. The online data is not moving to block the IP, the hard work of the crawler said to hang hang. A couple of days ago, a buddy complained that in order to catch the price data of e-commerce, his own broadband was blacklisted, and the network of the whole building was affected.
It's time for proxy IPs to come to the rescue. Simply putKnocking on doors with other people's house numbers.The door number of your own home is well hidden and not exposed. For example, if you want to collect data from a certain website and change a different IP for each request, the other party will not be able to tell whether it is a real person or a machine.
Look for these three things when choosing a proxy IP
There are all sorts of agency services on the market, so remember these three key points and don't lose out:
| typology | vantage | pothole |
|---|---|---|
| Data Center Agents | Fast speeds and low prices | easily recognized |
| Residential Agents | Real User IP | high cost |
| Dynamic Residential Agents | Automatic IP change | Need for technical interface |
I have to introduce my own products here.ipipgoThe dynamic residential agent, we specifically optimized for data collection scenarios. The actual test can switch 500,000+ IP addresses in a single day, the success rate can reach 98.7%, the key also supports pay per volume, especially suitable for small and medium-sized teams.
Hands-On Proxy Configuration
Take the Python crawler as an example and use the requests library as a demo:
import requests
from itertools import cycle
List of proxies provided by ipipgo (example)
proxies = [
'http://user:pass@gateway.ipipgo.com:8000',
'http://user:pass@gateway.ipipgo.com:8001', ...
... More proxies nodes
]
proxy_pool = cycle(proxies)
for page in range(1, 100):
current_proxy = next(proxy_pool)
try: current_proxy = next(proxy_pool)
response = requests.get(
proxies={"http": current_proxy}, timeout=10
timeout=10
)
Processing data...
except.
print(f "IP {current_proxy} hung, switching to next one automatically")
Note to set a reasonable timeout and exception handling, it is recommended to use with the random request header. ipipgo background can see the real-time API calls, which group of IP is blocked immediately replaced by a new one, this point is particularly worry-free.
A practical guide to avoiding the pit
I stepped on a mine last year when I was helping an AI company make a product price comparison system:
- Don't use an IP to death. - A single IP request more than 20 times in a row will hang.
- Pay attention to the frequency of requests - Even if you change your IP address, 10 requests per second will still reveal your identity.
- Regular data cleansing - Some sites return fake data to fool crawlers.
Later, with ipipgo's intelligent routing function, it automatically adjusts the request strategy according to the target website, and the collection efficiency directly doubled by 3 times. Their technical support also adjusted the geographical distribution, the proxy IP dispersed to more than 20 provinces, completely simulating the behavior of real users.
Frequently Asked Questions QA
Q: What should I do if my proxy IP is slow?
A: Prioritize geographically proximate nodes, ipipgo supports filtering proxies by city. If you go the API way to call, remember to turn on long connection reuse.
Q: How do I check if the proxy is in effect?
A: Use this detection code:
import requests
def check_proxy(proxy)::
try: resp = requests.get('')
resp = requests.get('http://httpbin.org/ip',
proxies={'http': proxy},
timeout=5)
return resp.json()['origin'] in proxy
except.
return False
Q: How do I break the CAPTCHA when I encounter it?
A: This belongs to the upgraded version of the anti-climbing, it is recommended to cooperate with ipipgo's browser fingerprinting camouflage service, lengthen the request interval to more than 30 seconds, and manually code when necessary.
Lastly, don't just look at the price when choosing a proxy service. Some of the cheap packages are actually a public proxy for the 10,000 riders, and it would be better to run around naked. ipipgo's exclusive proxy is a bit more expensive, but it's stable and secure, and it's especially suitable for commercial-grade data collection. New users register to send 5G traffic, enough to test.
