pip install --upgrade fasthttp

# ✅ Good: Use environment variables
import os
app = FastHTTP(
    get_request={
        "headers": {"Authorization": f"Bearer {os.getenv('API_TOKEN')}"},
        "timeout": 10,
    },
)

# ❌ Bad: Hardcoded credentials
app = FastHTTP(
    get_request={
        "headers": {"Authorization": "Bearer my-secret-token"},
    },
)

# Always set appropriate timeouts
app = FastHTTP(get_request={"timeout": 30})

# Prevent DoS with reasonable limits
app = FastHTTP(get_request={"timeout": 10})  # 10 seconds max

@app.post(url="https://api.example.com/data", json=data)
async def create_data(resp: Response):
    # Validate response
    if resp.status != 200:
        return f"Error: {resp.status}"

    try:
        result = resp.json()
        # Validate response structure
        if not isinstance(result, dict):
            return "Invalid response format"
        return "Success"
    except Exception:
        return "Invalid JSON response"

# Use virtual environments
python -m venv venv

• No hardcoded credentials
• Input validation present
• Error messages don't leak info
• Timeouts configured appropriately
• Dependencies are up to date

Issue: Without timeouts, requests can hang indefinitely.

Solution: Always configure timeouts:

app = FastHTTP(get_request={"timeout": 30})

Issue: Debug mode may expose sensitive information in logs.

Solution: Disable debug in production:

# Production
app = FastHTTP(debug=False)

# Development only
app = FastHTTP(debug=True)

Issue: Disabling SSL verification can expose to MITM attacks.

Solution: Always verify SSL certificates (default behavior).

Issue: Error messages might reveal internal information.

Solution: Use generic error messages in production.
