Python parsing JSON: Python proxy JSON parsing

Python Processing Proxy IP Data Essential Skills

Do network development brothers should understand that the proxy IP thing is like a courier relay station, can turn your network request to and fro. What we want to talk about today is how to use Python to play these proxy IP data out of the flower. Let's say we get a bunch of proxy IPs in JSON format from the server, how do we quickly filter out the ones we can use? There are a lot of doorways hidden here.

import requests
from json import JSONDecodeError

def get_proxies()::
    try: resp = requests.get('')
        resp = requests.get('https://api.ipipgo.com/proxy-list')
        return resp.json()['data']
    except JSONDecodeError: print("What a piece of shit interface!
        print("What the hell is this interface returning? It doesn't even look like JSON!")
        return []

A guide to common pitfalls in JSON parsing

There are three places where many newbies tend to fall:Incorrect data format,Coding issues,Exception handling is not done properlyFor example, the data returned by ipipgo's interface may sometimes carry special characters. For example, the data returned by ipipgo's interface may sometimes carry special characters, which can be used with thejson.loads()Parsing it directly will report an error.

Teach you a trick: first check the response header Content-Type is not application/json. sometimes the server jerked, obviously returned the HTML error page, but also hard to say that their return is JSON, you say angry not?

Proxy IP validity verification in practice

After getting the list of proxy IPs, you have to check them first. Here we recommend using ipipgo'sReal-Time Detection InterfaceThey have fast node updates and accurate detection results. Don't be stupid and write your own validation script, it's exhausting and error prone.

QA Session: Demining High Frequency Problems

Q：Why can't I connect with ipipgo's proxy?
A: Check the whitelist settings first, then try theirQuick access modeNew users tend to miss this configuration

Q：What should I do if I encounter a garbled code starting with u when parsing JSON?
A: add an ensure_ascii=False parameter in json.loads(), it works immediately!

Example of IPIPGO Service Integration

Finally, I'll give you a complete example of how to set up a proxy in three lines of code using ipipgo's SDK:

from ipipgo import ProxyClient

client = ProxyClient(api_key="your key")
proxies = client.get_verified_proxies(timeout=2)
print(f "Got {len(proxies)} available proxies, beautiful ~")

Pay attention to theirtraffic billing modelIf you're using it, go to your console and set up a usage reminder before you use it. Don't wait for the bill to come in before patting yourself on the back, I've seen it happen too many times. Their tech support is very responsive, and if you have a problem, you can just dislike the work order, better than trying to figure it out in the code yourself.
