Proxy Scrape

Project to receive, validate and store a list of free proxies.

Installation

• pip install -r .../Requirements.txt

Requirements

• argparse
• urllib3
• requests
• jinja2
• requests[socks]

---

• proxies_validator.py
• custom_arg_types.py

Usage

These initial lines are required in proxy_scrape.py for basic functionality.

import argparse
import csv
import json
import requests
import os
import time

from jinja2 import Template
from proxies_validator import test_servers
from custom_arg_types import str_bool_switcher_type, tuple_type

---

The Instance initially receives the arguments:

• -pem Certificate file path file.pem
• -to Time interval for testing each proxy server.

---

client = ProxyReceiver(args.certificate, args.time_out)

Overall arguments

• -p Receives a tuple of desired protocols for proxy server search eg: --protocols 'https', 'socks5'
• -l Limit of tested and valid proxies per protocol.
• -url API URL that will have the list of IP:PORT proxy servers, the {{protocol_value}} parameter is mandatory after the protocol= variable or any protocol type reference variable.
• -out It is the output folder that will have the csv file with the tested proxy list.

Functions

content = client.retrieve_free_proxy_list(args.link, protocol)

• Receives the list of API-URL proxy servers with all protocols selected in string.

---

client.write_valid_list(content, protocol, args.output_folder, args.limit)

• Test, validate (test_servers(...)) and save the ip:port and protocol in a csv file.

---

test_servers(protocol, row, self.sess, self.certificate, self.old_ip)

• Individual function that tests the connection to the server and validates IP filtering.

csv structure

url	port	protocol
123.456.78.90	1234	socks5
098.765.43.21	4321	https
.....

Custom arg classes

str_bool_switcher_type(arg)

• It is used by the --certificate(-pem) argument, dynamically switches between string, bool.
• str: When it is the path to the request certificate folder.
• bool, True: integrated certificate.
• bool, False: No check.

Usage example:

self.rex  =  self.sess.get('https://....', timeout=10, verify=self.certificate)

---

tuple_type(arg)

• It is used by the argument --protocols(-p), receives a list of protocols, eg: --protocols 'http', 'socks4'

Usage example:

for protocol in args.protocols:
        print(f'---\nProtocol selected: {protocol}')
     
	content = client.retrieve_free_proxy_list(args.link, protocol)
	client.write_valid_list(content, protocol, args.output_folder, args.limit)

---

proxies = {'http': f'{protocol}://{url}',
                'https': f'{protocol}://{url}'}

---

resp = self.sess.get('https://....', timeout=5, proxies=proxies, verify=self.certificate)
