Selenium Python WebDriver：如何消除‘DevTools listening...’提示

环境：Python 3.11
使用以下代码配置ChromeOptions启动WebDriver：

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("-incognito")
chrome_options.add_argument("disable-infobars"); # disabling    infobars
chrome_options.add_argument("--disable-extensions"); # disabling     extensions
chrome_options.add_argument("--disable-gpu"); # applicable  to  windows os  only
chrome_options.add_argument("--disable-dev-shm-usage"); # overcome  limited resource problems
chrome_options.add_argument("--no-sandbox"); # Bypass  OS security   model
chrome_options.add_argument(f"--headless={headless_option}")
chrome_options.add_argument("--disable-logging")
chrome_options.add_argument("--disable-crash-reporter")
chrome_options.add_argument("--disable-in-process-stack-traces")

service = Service(executable_path=executable_path)
driver = webdriver.Chrome(service=service, options=chrome_options)
url = r'https://www.google.com'
driver.get(url)
driver.quit()

尝试多种配置选项无效后，查看Selenium包中site-packages\selenium\webdriver\common\service.py文件的代码：

self.process = subprocess.Popen(
            cmd,
            env=self.env,
            close_fds=close_file_descriptors,
            stdout=cast(typing.Optional[typing.Union[int, typing.IO[typing.Any]]], self.log_output),
            stderr=cast(typing.Optional[typing.Union[int, typing.IO[typing.Any]]], self.log_output),
            stdin=PIPE,
            creationflags=self.creation_flags,
            startupinfo=start_info,
            **self.popen_kw,
        )

推测问题提示信息来自creationflags参数，寻求解决方法。

方法1：通过Service的popen_kw参数覆盖配置 #

初始化Service时，传入popen_kw指定自定义的creationflags，强制设置为0（恢复默认进程创建行为）：

service = Service(executable_path=executable_path)
# 覆盖creationflags参数
service.popen_kw['creationflags'] = 0
driver = webdriver.Chrome(service=service, options=chrome_options)

方法2：直接修改Service实例的creation_flags属性 #

如果方法1无效，直接修改Service的creation_flags属性：

service = Service(executable_path=executable_path)
service.creation_flags = 0
driver = webdriver.Chrome(service=service, options=chrome_options)

方法3：Windows系统专属配置 #

若运行环境为Windows，可配合startupinfo配置进一步调整：

import subprocess
service = Service(executable_path=executable_path)
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
service.startupinfo = startupinfo
service.creation_flags = 0
driver = webdriver.Chrome(service=service, options=chrome_options)

补充说明 #

creationflags是Windows系统下subprocess.Popen的专属参数，用于定义进程创建的特殊标志。Selenium默认可能设置了如CREATE_NO_WINDOW等标志，导致进程启动时出现异常提示或行为异常。设置creationflags=0会取消这些特殊标志，恢复系统默认的进程创建逻辑，大概率能解决相关问题。
