Undetected Chrome Driver随机停止（闲置问题）求助

以下是针对Undetected Chrome Driver随机停滞问题的具体修复方案：

1. 修复无效命令行参数 #

你的代码中----disable-javascript多了一个短横线，无效参数会导致Chrome启动或运行异常，应改为：

options.add_argument('--disable-javascript')

2. 优化Headless模式与稳定参数 #

添加更适合Headless运行的参数，避免渲染或检测问题：

options.add_argument('--headless=new')  # 使用新版Headless模式，兼容性更好
options.add_argument('--disable-gpu')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--window-size=1920x1080')

3. 调整页面加载策略 #

默认加载策略会等待所有资源加载完成，容易引发超时或停滞，改为仅等待DOM加载完成：

options.page_load_strategy = 'eager'

4. 增加重试机制与异常捕获 #

针对偶然的网络或加载问题，添加重试逻辑，同时捕获更多异常类型：

max_retries = 3
for link in url[:166]:
    retries = 0
    success = False
    while retries < max_retries and not success:
        try:
            driver.get(link)
            success = True
        except TimeoutException:
            retries += 1
            print(f"Timeout, retrying {retries}/{max_retries} for {link}")
        except Exception as e:
            print(f"Error loading {link}: {str(e)}")
            retries += 1

5. 定期清理状态与重启Driver #

长时间运行Driver易积累缓存或内存泄漏，每处理一定数量链接后重启Driver，并清理浏览器状态：

batch_size = 20  # 每20个链接重启一次
for idx, link in enumerate(url[:166], 1):
    if idx % batch_size == 0:
        driver.quit()
        driver = uc.Chrome(use_subprocess=True, options=options, service=Service(ChromeDriverManager().install()))
        driver.set_page_load_timeout(10)
    
    # 执行加载逻辑后清理状态
    driver.delete_all_cookies()
    driver.execute_script("window.localStorage.clear();")

完整优化代码 #

from selenium.common.exceptions import TimeoutException
import undetected_chromedriver as uc
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager

# 初始化浏览器配置
options = uc.ChromeOptions()
options.add_argument('--disable-extensions')
options.add_argument('--disable-javascript')
options.add_argument('--headless=new')
options.add_argument('--disable-backgrounding-occluded-windows')
options.add_argument('--disable-gpu')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--window-size=1920x1080')
options.page_load_strategy = 'eager'  # 设置DOM加载完成即停止等待

def init_driver():
    """封装Driver初始化逻辑，方便重启调用"""
    return uc.Chrome(use_subprocess=True, options=options, service=Service(ChromeDriverManager().install()))

driver = init_driver()
driver.set_page_load_timeout(10)

# 读取链接并过滤空行
with open('PlayerLinks.txt', 'r') as file:
    url = [line.strip() for line in file if line.strip()]

batch_size = 20
max_retries = 3

for idx, link in enumerate(url[:166], 1):
    # 定期重启Driver
    if idx % batch_size == 0:
        driver.quit()
        driver = init_driver()
        driver.set_page_load_timeout(10)
    
    # 重试加载逻辑
    retries = 0
    success = False
    while retries < max_retries and not success:
        try:
            driver.get(link)
            success = True
            # 清理浏览器状态
            driver.delete_all_cookies()
            driver.execute_script("window.localStorage.clear();")
        except TimeoutException:
            retries += 1
            print(f"Timeout, retrying {retries}/{max_retries} for {link}")
        except Exception as e:
            print(f"Error loading {link}: {str(e)}")
            retries += 1
    
    print(f"Processed {idx}/166: {link}")

# 最后关闭Driver
driver.quit()
