- Updated ProxyConfig.from_string to support multiple proxy formats, including URLs with credentials. - Deprecated the 'proxy' parameter in BrowserConfig, replacing it with 'proxy_config' for better flexibility. - Added warnings for deprecated usage and clarified behavior when both parameters are provided. - Updated documentation and tests to reflect changes in proxy configuration handling.

Proxy
Basic Proxy Setup
Simple proxy configuration with BrowserConfig:
from crawl4ai.async_configs import BrowserConfig
# Using HTTP proxy
browser_config = BrowserConfig(proxy_config={"server": "http://proxy.example.com:8080"})
async with AsyncWebCrawler(config=browser_config) as crawler:
result = await crawler.arun(url="https://example.com")
# Using SOCKS proxy
browser_config = BrowserConfig(proxy_config={"server": "socks5://proxy.example.com:1080"})
async with AsyncWebCrawler(config=browser_config) as crawler:
result = await crawler.arun(url="https://example.com")
Authenticated Proxy
Use an authenticated proxy with BrowserConfig:
from crawl4ai.async_configs import BrowserConfig
browser_config = BrowserConfig(proxy_config={
"server": "http://[host]:[port]",
"username": "[username]",
"password": "[password]",
})
async with AsyncWebCrawler(config=browser_config) as crawler:
result = await crawler.arun(url="https://example.com")
Rotating Proxies
Example using a proxy rotation service dynamically:
import re
from crawl4ai import (
AsyncWebCrawler,
BrowserConfig,
CrawlerRunConfig,
CacheMode,
RoundRobinProxyStrategy,
)
import asyncio
from crawl4ai import ProxyConfig
async def main():
# Load proxies and create rotation strategy
proxies = ProxyConfig.from_env()
#eg: export PROXIES="ip1:port1:username1:password1,ip2:port2:username2:password2"
if not proxies:
print("No proxies found in environment. Set PROXIES env variable!")
return
proxy_strategy = RoundRobinProxyStrategy(proxies)
# Create configs
browser_config = BrowserConfig(headless=True, verbose=False)
run_config = CrawlerRunConfig(
cache_mode=CacheMode.BYPASS,
proxy_rotation_strategy=proxy_strategy
)
async with AsyncWebCrawler(config=browser_config) as crawler:
urls = ["https://httpbin.org/ip"] * (len(proxies) * 2) # Test each proxy twice
print("\n📈 Initializing crawler with proxy rotation...")
async with AsyncWebCrawler(config=browser_config) as crawler:
print("\n🚀 Starting batch crawl with proxy rotation...")
results = await crawler.arun_many(
urls=urls,
config=run_config
)
for result in results:
if result.success:
ip_match = re.search(r'(?:[0-9]{1,3}\.){3}[0-9]{1,3}', result.html)
current_proxy = run_config.proxy_config if run_config.proxy_config else None
if current_proxy and ip_match:
print(f"URL {result.url}")
print(f"Proxy {current_proxy.server} -> Response IP: {ip_match.group(0)}")
verified = ip_match.group(0) == current_proxy.ip
if verified:
print(f"✅ Proxy working! IP matches: {current_proxy.ip}")
else:
print("❌ Proxy failed or IP mismatch!")
print("---")
asyncio.run(main())
