Proxy Credentials with Environment Variables
Never hardcode proxy credentials. Use environment variables instead.
TL;DR: Store proxy URLs in environment variables. Load them in your application. Use .env files for local development.
Setting Environment Variables
Linux/Mac
export HTTP_PROXY=http://user:pass@proxy:port
export HTTPS_PROXY=http://user:pass@proxy:port
Windows
set HTTP_PROXY=http://user:pass@proxy:port
set HTTPS_PROXY=http://user:pass@proxy:port
.env File
PROXY_HOST=proxy.nobleproxy.com
PROXY_PORT=8080
PROXY_USER=your_username
PROXY_PASS=your_password
Python Usage
import os
from dotenv import load_dotenv
load_dotenv()
proxy_url = f"http://{os.getenv('PROXY_USER')}:{os.getenv('PROXY_PASS')}@{os.getenv('PROXY_HOST')}:{os.getenv('PROXY_PORT')}"
Best Practices
- Never commit .env files
- Use secrets management in production
- Rotate credentials periodically
- Limit credential scope
