Here's one i coded in python3:
import requests
import sys
for line in open(sys.argv[1]).readlines():
line = line.strip()
proxy = {'proxy': line}
try:
status = requests.get('https://google.com', proxies=proxy)
if status.status_code == 200:
print(line)
except:
pass
usage:
- make a file with this format for each line: protocol://ip:port
- run the following command in the same directory as the proxy checker and proxy file
python3 proxy_checker.py proxies.txt
