How to Crawl Proxy IPs with a Crawler

How to Crawl Proxy IPs with a Crawler

Hello, everyone! Today I want to bring you to talk about, how to use crawler technology to grab some virtual proxy IP. ouch, this is a topic that makes me move it! Have you ever thought that every era has every era of play, this is our era of the most fashionable, coolest, hottest kind of play it!

The rapid development of the modern Internet has brought us a lot of convenience and opportunities. But sometimes, some nasty people always like to make trouble for us, access restrictions, blocking, etc., the crawler party but the bitter. However, as smart as we are, we can always find a way to solve the problem. Hey, hey, hey, in fact, it is very simple, we can capture the proxy IP to solve this problem, is not great!

Using Crawlers to Crawl Proxy IPs

Without further ado, I'll explain how to use crawler technology to capture these mysterious proxy IPs! First of all, we need to understand a truth, that is, the proxy IP are present in the Internet in the various sites.

Hey, my favorite thing is to use the little baby Python to write crawlers! That's right, Python, the crawler tool can help us achieve our goal easily. You can install Python first, and then use the following code example to crawl the proxy IP:

import requests

def get_proxy_ip(): url = '' # Replace with the URL of the proxy site.
url = 'http://www.proxy_ip_haha.com' # Replace with the URL of the proxy IP site.

proxies = {
'http': 'http://username:password@proxy_ip:proxy_port', # Replace the format of the proxy IP with the correct one, here's an example
'https': 'http://username:password@proxy_ip:proxy_port',
}

try.
response = requests.get(url, proxies=proxies, timeout=5)
if response.status_code == 200:: 'Catch proxy': 'Catch proxy'
return 'Captured proxy IP:' + response.text
else: return 'Caught proxy IP:' + response.text
return 'Crawl failed, boing boing...'
except requests.exceptions.RequestException as e:: return 'Crawl failed, reason is unknown.
return 'Crawl failed, calling...' except requests.exceptions.RequestException as e: return 'Crawl failed, calling...' + str(e)

print(get_proxy_ip())

I use the requests library here, by the way, added some proxy IP settings, to facilitate more flexible response to different situations. However, note that here is just a simple example of Oh, the specific proxy IP site to choose their own according to the actual situation.

Dynamic IP Proxy Pool for Crawlers

Hey, I believe you should know something about proxy IP! But I found a cooler way to operate, that is, dynamic IP proxy pool! This is the new favorite of the crawler world yo!

The principle of Dynamic IP Proxy Pool is very simple, that is, by constantly grabbing proxy IPs and managing the storage to realize the sustainable use of proxy IPs. I here recommend a very good Python library - ProxyPool, it can help us easily build their own dynamic IP proxy pool.

Uh-huh, I'll show you how to build a dynamic IP proxy pool using ProxyPool:

1. First, we need to install the ProxyPool library, which can be done by typing the following command at the command line:
"`shell
pip install ProxyPool
“`

2. Then, we need to create a new configuration file `config.ini` to configure some basic information, such as the database address, the running port of the crawler proxy IP, and so on.

3. Next, start the ProxyPool by entering the following command at the command line:
"`shell
ProxyPool
“`

4. Finally, we can then access the interface to get the proxy IP, for example:
“`
http://localhost:5555/random
“`

Is not very simple! Using ProxyPool, we can easily handle the construction of dynamic IP proxy pool, no longer need to worry about access restrictions!

summarize

I'm going to share this with you today! I hope that you can easily crawl through the crawler technology to capture the proxy IP they need to solve a variety of website access restrictions of the trouble.

Whether it's simply grabbing proxy IPs or using dynamic IP proxy pools, we need to be proficient in crawling techniques and apply them flexibly in combination with practical situations. I believe that through your own efforts and exploration, you will be able to become a good crawler party!
