Teach you to play with free proxy IP capture
Recently, a lot of friends asked me in a private letter, said those free proxy IP online in the end is not reliable. This is like the vegetable market to pick fruit, look at all the water, go home and cut may be half rotten. But don't worry, today to give you some dry goods, teach you how to use the crawler tool to sieve out the proxy IP can be used.
Can these tools really be whored out for nothing?
Let's start with a few of my own commonly used crawling tools, and note that these can only beemergency use, really need to work also depends on the professional services mentioned later:
A Python example
import requests
from bs4 import BeautifulSoup
def scrape_proxies(): url = 'a free proxy site'
url = 'a free proxy site'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
The exact parsing logic depends on the structure of the site
...
Here's a reminder that free agentsSurvival times generally do not exceed 2 hoursAnd a lot of them don't work at all. One time I tested 200 free IPs and only 3 worked, so I almost smashed my keyboard.
Free lunches don't taste good.
| Type of problem | probability of occurrence |
|---|---|
| Ultra-slow response | 80% and above |
| abrupt disconnection | 60% or so |
| IP blocked | 50% Probability |
Especially for those who are doing data collection, using a free IP may not get the target site to bepermanent blackout (law)I've had a project go south before!
How do you choose a reliable program?
This is the time to talk about the pros, ipipgo, who have anDynamic Residential AgentsIt's especially good for crawlers. When I used it for competitive analysis, it ran for three days straight without dropping out. The key is that the price is not expensive, the lowest 7 dollars more than 1 G traffic, cheaper than Starbucks medium cup.
Highlighting theirAPI ExtractionFeatures that are genuinely convenient:
Example of getting a proxy
import requests
api_url = "https://api.ipipgo.com/getproxy"
params = {
"key": "Your key",
"count": 5,
"protocol": "socks5"
}
response = requests.get(api_url, params=params)
Frequently Asked Questions QA
Q: What is the difference between dynamic and static proxies?
A: Dynamic IP will be changed regularly, suitable for regular collection; static IP is fixed, suitable for scenes that require long-term maintenance of the session
Q: How do I judge the quality of the agent?
A: mainly depends on the response speed (best within 200ms) and success rate, ipipgo background has real-time monitoring dashboards
Q: What should I do if my IP is blocked?

How to choose a savings package
It's more intuitive to go straight to the price list:
| Package Type | Applicable Scenarios | price of item |
|---|---|---|
| Dynamic Standard Edition | Individual users/small projects | 7.67 Yuan/GB/month |
| Dynamic Enterprise Edition | Teamwork/medium to large projects | 9.47 Yuan/GB/month |
| Static homes | Long-term data monitoring | 35RMB/IP/month |
Finally, if the project is in a hurry to go online or the amount of data, do not save this money. I have seen too many people in order to save agent money, the final project delay loss more. Tools are just means.Stable and reliable resourcesThat's the way to go.
