How to get free HTTP proxy IP address and how to use it

Free HTTP Proxy IP Address Acquisition

When doing web crawling, data collection or website access, we often encounter situations where IPs are blocked or access is restricted. The use of proxy IPs can avoid these problems and allow us to perform various network activities more smoothly. In this article, we will introduce a way to get a free HTTP proxy IP address.

To get free HTTP proxy IP addresses, you can get them through free proxy IP websites, which are regularly updated with free proxy IP addresses, and we can get and use these free proxy IP addresses with simple Python code.

import requests
from bs4 import BeautifulSoup

def get_free_proxy(): url = '' # Here is an example of ipipgo free proxy IP.
url = 'http://www.shenlongip.com/nn/' # Here's an example of ipipgo's free proxy IPs
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.text, 'lxml')
proxy_list = soup.select('#ip_list tr')

for i in range(1, len(proxy_list)): ip = proxy_list[i].
ip = proxy_list[i].select('td')[1].text
port = proxy_list[i].select('td')[2].text
type = proxy_list[i].select('td')[5].text
print(type.lower() + '://' + ip + ':' + port)

get_free_proxy()

The above code uses requests and BeautifulSoup library to get free proxy IP addresses from ipipgo free proxy IP website. In the actual crawler or network request, you can apply these free proxy IP addresses to the code, so as to achieve the purpose of hiding the real IP address.

Effectiveness of using free HTTP proxy IP address

After getting the free HTTP proxy IP address, we can apply it to our web requests, such as using the requests library for web access.

import requests

proxies = {
'http': 'http://123.123.123.123:8888',
'https': 'https://123.123.123.123:8888',
}

url = 'http://example.com'
response = requests.get(url, proxies=proxies)
print(response.text)

In the above code, we realize web access using proxy IP by assigning the obtained free proxy IP address to the proxies variable and passing the proxies variable as a parameter to the get method of the requests library.

It should be noted that the quality of free proxy IP addresses varies and some may be unstable or unusable. When using free proxy IPs, it is recommended to get more proxy IPs and test them, and choose the ones with better quality for use.

Overall, obtaining a free HTTP proxy IP address and applying it to web requests can be an effective solution to the problem of blocked IPs or limited access, facilitating our web activities.
