Python中chromedriver headless模式如何屏蔽日志
import selenium
from selenium import webdriver
from fake_useragent import UserAgent
ua = UserAgent()
option = webdriver.ChromeOptions()
option.add_argument(’–headless’)
option.add_argument(“window-size=1024,768”)
option.add_argument(’–start-maximized’)
option.add_argument(‘user-agent="%s"’%ua.random)
browser = webdriver.Chrome(executable_path=r’E:\selenium\chromedriver.exe’, chrome_options=option)
browser.get(‘https://www.baidu.com’)
browser.save_screenshot(r’D:\ok.png’)
chromedriver 在 headless 模式下运行会产生大量的日志信息, 请问如何屏蔽, 日志信息如下：
λ python demo.py

Python中chromedriver headless模式如何屏蔽日志
尝试指定日志文件（路径）
options.addArguments(“log-path=chromedriver.log”);
或
options.addArguments(“log-path=/dev/null”);
用 ChromeOptions 加 add_experimental_option 就能搞定。关键是把 excludeSwitches 设成 ['enable-logging']，再把日志级别调高。
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--headless')
# 关键在这两行，屏蔽控制台日志
chrome_options.add_experimental_option('excludeSwitches', ['enable-logging'])
chrome_options.add_argument('--log-level=3')
driver = webdriver.Chrome(options=chrome_options)
driver.get("https://www.example.com")
# ... 你的操作
driver.quit()
--log-level=3 把 Chromium 的日志级别设到 FATAL，基本就清净了。如果还有少量 DevTools 日志，可以再加个 --disable-dev-shm-usage 和 --no-sandbox（某些 Linux 环境需要），但主要就靠上面那两行。
总结：加两个选项就能清静。
将日志等级设定为 3 即可
chrome_options.add_argument(‘log-level=3’)
#info(default) = 0
#warning = 1
#LOG_ERROR = 2
#LOG_FATAL = 3
