Dynamic http proxy: dynamic HTTP proxy settings and application scenarios analysis

What is Dynamic HTTP Proxy? Find out before you get in the car!

Dynamic HTTP proxy is like a living water that changes its face, and it can change a new IP every time you request it. unlike those fixed IP proxies, its IP pool is deep and bottomless, which is especially suitable for scenarios where you need to change your armor frequently. For example, if you do data collection, with a static IP minutes by the site blocked, dynamic proxy can make you as slippery as a loach.

There is a misunderstanding here that must be made clear: dynamic ≠ omnipotent. Like ipipgo's dynamic residential package is divided into standard and enterprise standard two kinds, standard version for daily collection, enterprise standard version specializing in a variety of anti-climbing strict website. Don't be greedy and choose the wrong package, when the time comes to get stuck in the shell will be embarrassing.

Hands-on with value-assigned dynamic proxies (code practice)

In the case of the Python crawler, for example, it's super easy to use the requests library with proxies:

import requests

proxies = {
    'http': 'http://username:password@gateway.ipipgo.net:端口',
    'https': 'http://username:password@gateway.ipipgo.net:端口'
}

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

Watch this space.Username and password should be generated in advance in the consoleDon't copy my port number, everyone opens a different channel. If you get a 407 error, it's probably because the authentication info is wrong.

Don't use dynamic proxies in these five scenarios? It's a big loss

① E-commerce price comparison monitoring:Maximum 500 catches per day for the same store, with dynamic agents can bring the quota up to 5000+

QA session: a must-see pit stop for newbies

Q: What should I do if my agent is as slow as a snail?
A: First check whether the socks5 protocol, http protocol to go to the proxy will be faster 20%. ipipgo client has a smart routing function remember to open, can automatically select the fastest line.

Q: Why does authorization always fail?
A: In the case of 90%, the whitelist is not set correctly. In the console to add the local IP whitelist, don't be silly with the account password authentication. If it doesn't work, hurry up and ask their customer service for a new authorization code.

Q: Is it normal for traffic to fly by?
A: Check if you don't turn off automatic browser updates. There is a brother with Chrome auto-update on, and it ran 50G of traffic in one night, a bloody loss! It is recommended to set max_retries=3 in the code to prevent repeated requests.

Finally nagging sentence: do not buy cheap pheasant agent, before I have seen someone greedy cheap to buy 9.9 monthly, the results of the IP is all blacklisted, the data pick back all the chaos. Regular agents like ipipgo haveRequest Success Rate MonitoringIf you have less than 95%, you can directly contact customer service to make up the traffic.
