Python Requests Library Authentication Configuration Full Tutorial

Hands-on with Python Requests for Proxy IP Configuration

Those of you who are engaged in web requests should have encountered the situation of having your IP blocked by the target website, right? That's when you need a proxy IP to save the day. Today, we will take the Python Requests library to teach you how to configure the proxy IP clearly. Pay attention to the key points, especially the authentication configuration part, many tutorials do not tell the whole story.

Basic Configuration: Putting a Vest on Requests

Let's start with a piece of useful code and save this template below:

import requests

proxies = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:9021',
    'https': 'http://用户名:密码@gateway.ipipgo.com:9021'
}

response = requests.get('destination URL', proxies=proxies, timeout=10)

Pay attention here.The username and password should be exactly the same as the one given to you by the proxy service provider.The username of ipipgo is usually in the format of "business code_random character", don't make it up yourself. That port 9021 is the special port for their dynamic residential proxy, don't use it wrong.

The Five Pitfalls of Certification Failure

Newbies are most likely to fall in the authentication configuration, here are a few common minefields:

Practical Tips: Keeping Agents Steady as Old Dogs

Recommended for ipipgoDynamic Residential AgentsThe company has a unique feature - automatic IP change per request. it's easy to configure:

from requests.auth import HTTPProxyAuth

auth = HTTPProxyAuth('business code', 'dynamic key')
response = requests.get(url, proxies=proxies, auth=auth)

This dynamic key is available in real time in the ipipgo backend and is much safer than a fixed password. Remember to setDon't exceed the timeout parameter by more than 15 secondsIf the site is slow to respond, you should give up and move to the next IP.

QA time: a must for newbies

Q: What should I do if my agent suddenly fails?
A: first ping gateway.ipipgo.com to see the network pass or not, and then with no authentication request test, if the return 407 that the proxy itself is not a problem!

Q: How can I increase the request speed?
A: Change the Accept-Encoding in the request header to gzip, which can compress the transmitted data. ipipgo's BGP line itself has low latency, so don't blindly optimize it yourself!

Q: What should I do if I encounter a website CAPTCHA?
A: It means that the current IP is marked, immediately switch IP. ipipgo's traffic pool has millions of IP reserves, change the region parameters to re-request on the line!

Q: HTTPS website request failed?
A: Change the proxy protocol from http to https, or on the socks5 proxy. ipipgo's socks5 port is 9011, remember to change the authentication method.

Upgrade Play: Automated Agent Management

A tawdry operation for the older birds - managing proxies with session objects:

session = requests.Session()
session.proxies.update(proxies)
session.auth = HTTPProxyAuth('business code', 'dynamic key')

 All subsequent requests are automatically proxied
response1 = session.get('url1')
response2 = session.post('url2')

This not only reuses TCP connections, but also handles cookies automatically. with ipipgo'squantity-based billing package, doing a crawler project can save a lot of silver.

Finally remind, choose the proxy service provider to look at three points: IP pool size, authentication protocol support, response speed. Like ipipgo this support http/https/socks5 all protocols, but also has a dedicated client tool, with a really save. They also recently came out with aIntelligent Routing FunctionIt can automatically select the fastest access node, so you can try it if you need high concurrency.
