Proxy IP Parsing JSON Files (Python): Python Proxy IP Parsing JSON

Hands-On Proxy IP Stuffing for Python Work

Crawler brothers understand that no proxy IP is like riding a bicycle on the highway - simply can not run up. Today we will nag how to use Python to proxy IP from the JSON file out of the use, and incidentally Amway's own good ipipgo service.

What does a JSON file look like?

The proxy IP's JSON file usually looks like this (note that looking at the field names may change):

{
    "proxy_list": [
        { "ip": "123.45.67.89", "port": 8080, "type": "http"}, { "ip": "98.76.54.32", "port": 3128, "type": "https"}, }
        {"ip": "98.76.54.32", "port": 3128, "type": "https"}
    ]
}

Focus on three parameters:ip address,port number,Agent TypeThe fields may be called host, port, protocol. Different service providers may give fields called host, port, protocol, so remember to look at the structure first.

Python disassembly in four steps

Let's use the most basic requests library to demonstrate, the old driver directly look at the code:

import json
import requests

 Step 1: Open the file
with open('ipipgo_proxies.json') as f:
    data = json.load(f)

 Step 2: Fish the data
proxy = data['proxy_list'][0] take the first proxy
proxy_str = f"{proxy['ip']}:{proxy['port']}"

 Step 3: match the parameters
proxies = {
    'http': f "http://{proxy_str}",
    'https': f "https://{proxy_str}"
}

 Step 4: Send the request
try.
    response = requests.get('http://测试网址', proxies=proxies, timeout=10)
    print("Request successful! Status code:", response.status_code)
except Exception as e.
    print("Rollover! Error message:", str(e))

Focused attention:Proxy type should be written in full(http/https), don't set the timeout to more than 10 seconds, use ipipgo's proxy and remember their survival time settings.

Agent Pool Maintenance Tips

A single agent is easy to hang, it is recommended to get a pool of agents to use in turn:

If you use ipipgo, you can directly call their API to get the latest proxy, which is much more convenient than locally maintaining JSON files. Their proxy survival rate can reach 95% or more, than self-built proxy pool to save effort.

Frequently Asked Questions QA

Q：JSON file parsing error report what to do?
A: First check if the file encoding is UTF-8, then see if the field names match. With ipipgo's proxy you can directly use the standard format they provide, saving the trouble of format conversion.

Q: What should I do if my agent suddenly fails?
A: It is recommended to do abnormal retry mechanism, 3 consecutive failures to change the proxy. ipipgo's proxy has real-time monitoring function, the failure of the proxy will be automatically off the shelf.

Q: What if I need a High Stash Agent?
A: Choose the "High anonymity" package in the ipipgo background, the request header will completely hide the client information, suitable for scenarios that require high privacy.

Why ipipgo?

You have to brag twice about your own product:
1. Nationally uniquedynamic port technologyThe anti-blocking effect is outstanding.
2. Support for pay-per-use, how much is used?
3. 7 × 24 hours technical support, response time is twice as fast as the counterparts
New users get 500 free trials for signing up, enough to run a small program.

The last nagging sentence: proxy IP is not a panacea, with a reasonable request frequency to get twice the result with half the effort. Encounter specific problems can be directly poked ipipgo official website to find technical customer service, their engineers are much more professional than ordinary customer service.
