Improve code quality, documentation, and maintainability

[Copilot]

Comprehensive refactoring to bring the codebase to production standards without altering functionality.

Code Quality

• Type hints: Added to all functions for better IDE support and type safety
• Docstrings: Added comprehensive documentation with Args/Returns/Raises sections
• Error handling: Replaced bare except with specific exception types (requests.RequestException, json.JSONDecodeError)
• Logging: Introduced structured logging while preserving user-facing print statements
• Network resilience: Added timeout parameters (REQUEST_TIMEOUT=10s, RETRY_TIMEOUT=15s) to prevent indefinite hangs

Code Style (PEP 8 Compliant)

• Removed trailing whitespace and fixed blank line spacing
• Fixed unreachable code after raise statements
• Normalized line endings (CRLF → LF)
• Removed debug artifacts (dumpResponse function)

Project Infrastructure

• requirements.txt: Explicit dependency management (requests>=2.25.0, beautifulsoup4>=4.9.0)
• .gitignore: Prevents committing generated files (response.html, debug_results.json, __pycache__)

Documentation

• Enhanced README with feature list, installation steps, and usage examples
• Added system requirements section
• Improved formatting with badges and clearer structure

Security

Passed CodeQL security scan with 0 alerts.

Before:

def get_CityName():
    timestamp = str(int(round(time.time() * 1000)))
    url = 'http://wgeo.weather.com.cn/ip/?_='+timestamp
    try:
        res = requests.get(url, headers=create_headers())
    except:
        # Bare except, no timeout, unclear error handling
        ...

After:

def get_CityName() -> Tuple[str, str]:
    """
    Automatically detect the user's city based on their IP address.
    
    Returns:
        Tuple of (city_name, city_code). Returns empty strings if detection fails.
    """
    timestamp = str(int(round(time.time() * 1000)))
    url = f'http://wgeo.weather.com.cn/ip/?_={timestamp}'
    
    try:
        res = requests.get(url, headers=create_headers(), timeout=REQUEST_TIMEOUT)
        res.raise_for_status()
    except requests.RequestException as e:
        logger.warning(f"首次请求失败: {e}")
        # Retry logic with proper error handling
        ...

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• d1.weather.com.cn
  • Triggering command: /usr/bin/python3 python3 GetWeather.py --debug --city 101010100 (dns block)
• j.i8tq.com
  • Triggering command: /usr/bin/python3 python3 GetWeather.py --debug --city 101010100 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
