Add demo script for proxy rotation and quick test suite
- Implemented demo_proxy_rotation.py to showcase various proxy rotation strategies and their integration with the API. - Included multiple demos demonstrating round robin, random, least used, failure-aware, and streaming strategies. - Added error handling and real-world scenario examples for e-commerce price monitoring. - Created quick_proxy_test.py to validate API integration without real proxies, testing parameter acceptance, invalid strategy rejection, and optional parameters. - Ensured both scripts provide informative output and usage instructions.

Proxy Rotation Demo Script
|
||||
|
||||
This script demonstrates real-world usage scenarios for the proxy rotation feature.
|
||||
It simulates actual user workflows and shows how to integrate proxy rotation
|
||||
into your crawling tasks.
|
||||
|
||||
Usage:
|
||||
python demo_proxy_rotation.py
|
||||
|
||||
Note: Update the proxy configuration with your actual proxy servers for real testing.
