Installation
pip install multi-browser-crawler
Quick Start
import asyncio
from multi_browser_crawler import BrowserPoolManager, BrowserConfig
async def main():
# Simple configuration
config = BrowserConfig(headless=True, timeout=30)
pool = BrowserPoolManager(config.to_dict())
try:
await pool.initialize()
# Fetch HTML
result = await pool.fetch_html(
url="https://example.com",
session_id="my_session"
)
if result['status']['success']:
print(f"✅ Success! Title: {result.get('title', 'N/A')}")
print(f"HTML size: {len(result.get('html', ''))} characters")
else:
print(f"❌ Error: {result['status'].get('error')}")
finally:
await pool.shutdown()
if __name__ == "__main__":
asyncio.run(main())
Configuration Options
config = BrowserConfig(
headless=True, # Run in headless mode
timeout=30, # Page load timeout (seconds)
min_browsers=1, # Minimum browsers in pool
max_browsers=5, # Maximum browsers in pool
proxy_url="http://proxy:8080", # Optional proxy URL
download_images_dir="/tmp/images" # Image download directory
)
API Methods
fetch_html()
result = await pool.fetch_html(
url="https://example.com",
session_id="optional_session", # For persistent sessions
timeout=30, # Request timeout
api_patterns=["*/api/*"], # Capture API calls
images_to_capture=["*.jpg", "*.png"] # Download images
)
Response format:
{
'status': {'success': True, 'url': '...', 'load_time': 1.23},
'html': '<html>...</html>',
'title': 'Page Title',
'api_calls': [...], # Captured API requests
'images': [...] # Downloaded images
}
Session Management
# Persistent session - maintains cookies/state
result1 = await pool.fetch_html(url="https://site.com/login", session_id="user1")
result2 = await pool.fetch_html(url="https://site.com/profile", session_id="user1")
# Non-persistent - fresh browser each time
result3 = await pool.fetch_html(url="https://site.com", session_id=None)
Proxy Support
# Single proxy
config = BrowserConfig(proxy_url="http://proxy:8080")
# The package integrates with rotating-mitmproxy for advanced proxy rotation
Testing
# Run all tests
python -m pytest tests/ -v
# Run specific test categories
python -m pytest tests/ -m "not slow" -v
