Proxy IP access to public web pages: Proxy IP access to public web pages anonymously

What is a proxy IP? Let's find out before we start.

To put it bluntly, a proxy IP is like a collection point used in online shopping. For example, if you want to buy goods from a certain treasure but do not want to expose your own address, find a proxy point of transit. Similarly, when surfing the Internet with a proxy IP server transit, the target site to see the proxy address rather than your real IP. ipipgo such service providers specializing in the provision of such a "collection point" service, so as to save yourself from tossing the server.

There are three common types of agents that have to be identified:

Teach you how to use proxy IP to access the web.

As an example, the Python crawler is in place in three steps with ipipgo's proxy service:

import requests

 Proxy information from the ipipgo backend
proxy = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:9020',
    'https': 'http://用户名:密码@gateway.ipipgo.com:9020'
}

response = requests.get('destination URL', proxies=proxy)
print(response.text)

Key Points:Remember to change your username and password to the account you registered with ipipgo, and fill in the port number according to the type of package you purchased. It is recommended to take the free test agent first to test the waters, to confirm the availability and then on the official environment.

Avoiding the Eight Pitfalls in Proxy Use

1. Sudden IP failure: choose ipipgo such dynamic rotation of IP pool service providers, single IP failure automatic switching
2. Slow access: preferredgeographically closenodes, for example, don't use US proxies to climb domestic sites
3. Recognized by websites: Regular cleaning of browser fingerprints, with random User-Agent switching
4. Certificate errors: remember to deal with SSL certificate validation when enabling proxies
5. Account blocking: avoid high-frequency operations and set reasonable request intervals
6. Proxy does not work: first use curl to test the basic connectivity and then debug the code
7. Traffic anomalies: monitoring agent traffic consumption, anti-program dead loop
8. Legal risks: never use proxies for illegal activities

A must-see QA session for the little guy

Q: What's the difference between a free proxy and a paid proxy?
A: It's like a public restroom and your own bathroom. Free proxy IP pools are small, slow, insecure, and can be hijacked by the middle. ipipgo such professional service providers offer exclusive bandwidth with automatic verification and IP cleaning.

Q: Why can't I connect to my agent?
A: First check whether the three elements: IP address, port and authentication information are correct. Then use telnet to measure the port pass or fail:

telnet gateway.ipipgo.com 9020

If the connection fails, it may be that the local firewall is blocked, or the proxy service has expired.

Q: How can I tell if a proxy is anonymous?
A: Visitswhatleaks.comThis type of testing site. Focus on the headers X-Forwarded-For and Via to see if they give away the real IP.

Choose the right service provider to save half the trouble

It's not for nothing that ipipgo has been in the industry for seven years, three hardcore advantages:
1. National coverage of 200 + city nodes, switch at any time without leaving traces
2. Unique IP health monitoring system, automatic filtering of invalid proxies
3. 7 × 24 hours real technical support, response speed 3 times faster than peers

Especially brothers who do e-commerce price comparison, use himResidential AgentsService, perfect simulation of real user behavior. Last week, a customer with a dynamic residential IP crawl data, ran for a month without triggering anti-climbing, the stability can really beat.

The last nagging sentence: technology is a double-edged sword, the proxy IP with a good efficiency of the magic weapon, chaotic use may cause trouble. Comply with the website robots agreement, control the frequency of requests, and be an ethical crawler engineer. Don't be so hard on yourself when you run into problems, just look for ipipgo technical tips, it's more reliable than searching for tutorials on the internet.
