Tools and methods for HTTP proxy extraction

On the Internet, the use of HTTP proxies is a common technical tool used to hide the real access address and improve access speed. However, finding a reliable HTTP proxy is a challenge. The following will introduce some common HTTP proxy extraction tools and methods to help you quickly get valid proxy information.

First, we can use the requests library in the Python language to get a free HTTP proxy. Here is a simple example code:

import requests

url = 'https://www.free-proxy-list.net/'
response = requests.get(url)
print(response.text)

The above code uses the requests library to send a request to a free proxy website and outputs the content of the web page. By parsing the web page content, we can extract the proxy information in it.

除了使用requests库外，还有一些第三方的HTTP代理提取工具，例如ProxyBroker、Scraipipgo-Proxy、Proxy_List等。这些工具可以帮助我们快速获取大量的HTTP代理信息，但是使用时需要注意隐私安全和可靠性。

Recommended tools for HTTP proxy extraction

When choosing an HTTP proxy extraction tool, we need to consider the tool's stability, update frequency, proxy quality and other factors. The following are some of the more recommended HTTP proxy extraction tools:

1. ProxyBroker: This is a proxy acquisition tool based on Python asyncio , you can get proxies through various ways , and provides filtering , testing and other functions .

2. Scraipipgo-Proxy：基于Scraipipgo框架的代理获取工具，可以编写爬虫来获取各种来源的代理，并支持异步测试代理的有效性。

3. Proxy_List: provides a variety of language interfaces , including Python, Node.js , etc., can be easily integrated into their own projects to get the latest HTTP proxy information .

All of the above tools are open source projects and their source code can be found and used on platforms such as GitHub. Of course, when using any proxy, you need to pay attention to legality and privacy security to avoid violating national laws or causing unnecessary risks.
