Proxy IP Implementation for Python HTTP Requests: Configuring Proxy IP for Python Requests

Teach you to use Python Requests to hang a proxy IP handily

We do web crawler brothers understand that there is no reliable proxy IP simply can not play. Today, how to use Python's Requests library to configure the proxy, the key recommendationipipgoThis bearer service provider is as stable as it gets in person.

What's the point of a proxy IP anyway?

Simply put, it is to give your network request a vest, so that the target site can not recognize your real IP, especially when doing data collection, with a proxy can effectively avoid being ban. a chestnut, a treasure commodity price monitoring, if you do not use the proxy minutes to give you IP blocking.

Real-world configuration tutorials

First install the requests library, this need not be said, right? Directly on the dry code:

import requests

 Proxy information copied 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'
}

try.
    response = requests.get('https://目标网站.com', proxies=proxy, timeout=10)
    print(response.status_code)
except Exception as e.
    print(f'Request gone wrong: {str(e)}')

Focused attention:The proxy address of ipipgo should be authenticated with an account password, and should never be written directly into the dead code. It is recommended to use configuration files or environment variables to save sensitive information.

Guide to avoiding the pit

Three common mistakes newbies make:

1. Proxy format is written wrong - http and https should be configured separately
2. The timeout is not set - it is recommended that the timeout be no more than 15 seconds.
3. Didn't handle exceptions - it's embarrassing to crash the program directly when the network fluctuates

Why ipipgo?

Proxy service providers on the market are a mixed bag, and I've stepped in a lot of potholes. There are three main things I look for in ipipgo:

• Dynamic residential IP, realism pulled full circle
• Node coverage in 200+ cities nationwide
• Dedicated customer service responds quickly and you can find someone in the middle of the night if you have a problem

Frequently Asked Questions QA

Q: What should I do if the agent suddenly fails to connect?
A: First check whether the account is expired, and then try different geographical nodes. ipipgo background can view the connection status in real time, it is recommended to turn on the automatic switching function.

Q: The code reports a 407 authentication error?
A：九成九是账号密码输错了，注意特殊字符要URL编码。比如密码里有@符号的话，得替换成%40。

Q: How do I test if the proxy is working?
A: Visit the address httpbin.org/ip to see if the returned IP is a proxy IP. It is recommended to add a detection logic in the code to automatically verify before each request.

advanced skill

If you need multi-threaded collection, it is recommended to match with ipipgo's API to dynamically acquire proxy pool. So that each thread with a different IP, efficiency directly take off:

from concurrent.futures import ThreadPoolExecutor

def worker().
     Call the ipipgo API to get a temporary proxy.
    proxy = get_proxy_from_ipipgo()
    requests.get(url, proxies=proxy)

with ThreadPoolExecutor(max_workers=20) as executor.
    executor.map(worker, range(100))

Lastly, proxy IPs are not a panacea, and a reasonable frequency of requests is the only way to ensure a long-lasting solution. Don't be hard on yourself when you encounter problems, just go to ipipgo's tech support, they know how to deal with this kind of problem.
