How to verify proxy IP availability with Python? Detailed steps are here!

Why should I verify the availability of a proxy IP?

Verifying the availability of a proxy IP is a very important step before using it. Whether it's to ensure speed and stability or to avoid request failures, validation can help you filter out high-quality proxy IPs.

Preparation tools

Python is a great language for handling web requests, mainly because of its powerful third-party libraries. We'll be using the `requests` library to send HTTP requests, which is easy to use and perfect for this task. If you haven't installed this library yet, you can do so via `pip install requests`.

Write validation code

Next, let's write a simple Python script for verifying that a proxy IP is available. We'll send a request to a website, say `http://httpbin.org/ip`, which will return the IP address of the request, making it easy for us to check if the proxy is working.

import requests

def check_proxy(proxy)::
try.
response = requests.get('http://httpbin.org/ip', proxies={'http': proxy, 'https': proxy}, timeout=5)
if response.status_code == 200:: print(f "http': proxy, 'https': proxy}, timeout=5)
print(f "Proxy IP {proxy} available")
print("Returned IP:", response.json()['origin'])
else.
print(f "Proxy IP {proxy} not available, status code: {response.status_code}")
except requests.exceptions.RequestException as e: print(f "Proxy IP {proxy} not available, status code: {response.status_code}")
RequestException as e: print(f "Proxy IP {proxy} not available, error: {e}")

# Example Proxy IP
proxy_ip = "http://123.456.789.012:8080"
check_proxy(proxy_ip)

code resolution

In this script, we define a `check_proxy` function. It accepts a proxy IP as a parameter and then sends the request via the `requests.get` method. We set a timeout to avoid long waits for unresponsive proxies. Based on the returned status code and IP address, we can determine if the proxy IP is available.

Bulk Proxy IP Verification

If you have multiple proxy IPs that need to be verified, you can put them in a list and use a loop to verify them one by one. This will automate the filtering of available proxy IPs and increase efficiency.
