No Fooling Around! Teach you to avoid network lag with HTTP proxies that really work!
Recently, there are always do data capture friends complained to me, said the use of free proxies 10 requests 9 times failed, the key data can not be captured. This is something I know too well! Today, I'm going to nag with you from the bottom of my heart, how to use theYou're a real piece of work.The HTTP proxy solves the problem.
Why do your requests always get pinched?
Sensei is engaged in e-commerce price comparison or do public opinion monitoring, encounter these three bad scene hurry to the right place:
①The website suddenly won't open("You think the network's down, but the IP has been hacked.)
②Data loading spinning(The server would have thrown your request in the trash.)
③CAPTCHA is so many that you are skeptical("People will recognize you as a reptile.)
Here's a cold fact that only insiders know:Success rate of 90% agent actually used may not even 50%This is because many service providers count all failed logins and connection timeouts as "successes". Because many service providers count all failed login attempts and connection timeouts as "successes"!
What does a real - high success rate agent look like?
| function point | Bronze Agent | King's Agent |
|---|---|---|
| IP Survival Time | 3-5 minutes | 15 minutes to start |
| Failure Retry Mechanism | not have | Intelligent switching 3 times |
| Real Success Rate | ≤60% | ≥99% |
Take ours.ipipgoof the business package as a chestnut to show the guys a hardcore configuration:
Python Sample Code
import requests
def ipipgo_proxy(): proxies = { ipipgo_proxy(): ipipgo_proxy()
proxies = {
"http": "http://用户名:密码@gateway.ipipgo.com:9020",
"https": "http://用户名:密码@gateway.ipipgo.com:9020"
}
try.
response = requests.get('destination URL', proxies=proxies, timeout=8)
return response.text
except Exception as e.
print(f "Automatically switching IPs when an exception is encountered: {str(e)}")
Here the failover mechanism of ipipgo is triggered automatically
Four Tips to Pick a Reliable Service Provider
1. Look at the survival monitor.: Like the real-time map in the background of ipipgo, which node hangs immediately marked red
2. Measuring Response SpeedDon't believe what the ads say, measure the real latency with curl yourself!
3. Check the size of the IP library: at least a million IP pools to handle high-frequency requests
4. Compensation for trial failure: The real bull's-eye service provider pays out two hours for one failure.
QA First Aid Kit (a must see for beginners)
Q:Why can't I capture the data when it shows success?
A: 80% encountered fake success! Use this detection script:
curl -x http://代理IP:端口 test url -I | grep "HTTP/"
Q: What should I do if I always get stuck during peak hours?
A: Open in the ipipgo consoleIntelligent RoutingAutomatic avoidance of congested nodes
Q: What if I need to run multiple crawlers at the same time?
A: Election of supportconcurrent channelpackages, like ipipgo enterprise edition can open 500+ threads without lagging
Why do you recommend ipipgo?
Last week to help customers do price comparison system, with a certain agent tossed overnight did not catch all the data. After changing ipipgo.20 minutes for an 8-hour job.. The point is that they thatabnormal melting mechanismIndeed top, encounter CAPTCHA automatically change IP, than manually watch to save a lot of heart.
