Do free proxies work or not? Read these three potholes first

Online random search "free proxy" can pop up hundreds of lists, but really use up nine out of ten is the pit. The most common arebe slow as a dog-Open a web page to turn half a minute, brush the video directly stuck into PPT. last month I tested a popular proxy list, only 3 out of 20 addresses can connect properly, the success rate is not as good as flipping a coin.

What's more pitiful is the security issue. There is a friend who does e-commerce has used a free proxy to log in the background, the result is that the account receives a reminder of off-site logging two or three days. Later, he found that the free proxy server was actually secretly recording his cookie data. So.Don't use wild proxies for operations involving account loginI don't even know who to cry to if I lose my password.

Three Tips to Pick Free Proxies That Work

If you have to use a free proxy, remember this filtering mantra:First, measure the speed, second, check the agreement, and third, look at the territoryThe first thing you need to do is to check the speed. First of all, the speed test, do not believe in the response time labeled on the site, use the curl command to try the most reliable:

curl -x http://代理IP:端口 -o /dev/null -s -w "elapsed time: %{time_total}s" https://example.com

More than 5 seconds of direct pass. protocol focus on whether to support HTTPS, and now there are only HTTP agents with open-top trucks to transport money as dangerous. The geographical selection is delicate, do cross-border e-commerce nodes near the target market, such as doing the U.S. station to pick Chicago or Dallas agent.

Free vs. self-build vs. professional services How to choose without stepping on the line

Here's a comparison chart for you to understand:

Previously, there is a crawler studio, the beginning of the cheap map with a free proxy, the results of the project yellow twice. Later changed to ipipgo exclusive IP pool, data collection efficiency directly tripled, the key is no longer encountered CAPTCHA bombing.

Hands-on with ipipgo Proxy

Using a professional service is actually much easier than tossing a free proxy. After signing up for an ipipgo account, find the backend of the"Get Proxy"button, pick the desired region and protocol type. For example, if you do social media management, you can choose static residential IP, and use dynamic data center IP for crawler business.

Here's a Python sample code:

import requests

proxies = {
  'http': 'http://用户名:密码@gateway.ipipgo.com:端口',
  'https': 'http://用户名:密码@gateway.ipipgo.com:端口'
}

resp = requests.get('https://你的目标网站', proxies=proxies)
print(resp.status_code)

Note that you have to change the username and password to the authentication information of your own account, and the port number can be found in the access document in the background. Encounter connection problems first check the whitelist settings, some platforms need to bind the local IP in advance.
