From d2759824ef8e007bfc4fff3deb61d4b0e777cc44 Mon Sep 17 00:00:00 2001 From: AHMET YILMAZ Date: Tue, 15 Jul 2025 15:09:53 +0800 Subject: [PATCH] fix: Update playwright-stealth to v2.0.0+ compatibility Fixes #1273 - Replace deprecated stealth_async import with Stealth class - Add stealth flag to BrowserConfig (default: true) - Update async_crawler_strategy to use Stealth().apply_stealth_async() - Remove obsolete StealthConfig from browser_manager - Maintain backward compatibility with existing stealth functionality This fixes compatibility issues with playwright-stealth v2.0.0+ where the API changed from stealth_async function to Stealth class. test: Add comprehensive tests for playwright-stealth v2.0.0+ compatibility - Test Stealth class import and instantiation - Test apply_stealth_async method availability - Test BrowserConfig stealth flag functionality - Test stealth flag serialization - Verify backward compatibility with existing stealth functionality --- crawl4ai/async_configs.py | 2 + crawl4ai/async_crawler_strategy.py | 6 +++ crawl4ai/browser_manager.py | 16 ------- test_stealth_compatibility.py | 76 ++++++++++++++++++++++++++++++ 4 files changed, 84 insertions(+), 16 deletions(-) create mode 100644 test_stealth_compatibility.py diff --git a/crawl4ai/async_configs.py b/crawl4ai/async_configs.py index d96916b4..db1fbd9b 100644 --- a/crawl4ai/async_configs.py +++ b/crawl4ai/async_configs.py @@ -389,6 +389,7 @@ class BrowserConfig: self, browser_type: str = "chromium", headless: bool = True, + stealth: bool = True, browser_mode: str = "dedicated", use_managed_browser: bool = False, cdp_url: str = None, @@ -426,6 +427,7 @@ class BrowserConfig: ): self.browser_type = browser_type self.headless = headless + self.stealth = stealth self.browser_mode = browser_mode self.use_managed_browser = use_managed_browser self.cdp_url = cdp_url diff --git a/crawl4ai/async_crawler_strategy.py b/crawl4ai/async_crawler_strategy.py index 9fdb0fe2..02320dfe 100644 --- a/crawl4ai/async_crawler_strategy.py +++ b/crawl4ai/async_crawler_strategy.py @@ -6,6 +6,7 @@ import time from abc import ABC, abstractmethod from typing import Callable, Dict, Any, List, Union from typing import Optional, AsyncGenerator, Final +from playwright_stealth import Stealth import os from playwright.async_api import Page, Error from playwright.async_api import TimeoutError as PlaywrightTimeoutError @@ -532,6 +533,11 @@ class AsyncPlaywrightCrawlerStrategy(AsyncCrawlerStrategy): # Get page for session page, context = await self.browser_manager.get_page(crawlerRunConfig=config) + # Apply stealth measures if enabled + if self.browser_config.stealth: + stealth = Stealth() + await stealth.apply_stealth_async(page) + # await page.goto(URL) # Add default cookie diff --git a/crawl4ai/browser_manager.py b/crawl4ai/browser_manager.py index 6ee43961..e952cc92 100644 --- a/crawl4ai/browser_manager.py +++ b/crawl4ai/browser_manager.py @@ -14,24 +14,8 @@ import hashlib from .js_snippet import load_js_script from .config import DOWNLOAD_PAGE_TIMEOUT from .async_configs import BrowserConfig, CrawlerRunConfig -from playwright_stealth import StealthConfig from .utils import get_chromium_path -stealth_config = StealthConfig( -
