如何在python中为chromedriver和pyinstaller exe压缩错误消息？

我注意到当我在pyinstaller中使用chromedriver并运行它时，我得到一个错误消息列表。我一直试图删除它们但到目前为止没有运气。 更新：似乎无头旗帜引起了很多悲痛。

Improvement, now how to remove this in headless.

代码：

options = Options()
options.add_argument('--headless')
options.add_argument('--hide-scrollbars')
options.add_argument('--disable-gpu')
driver = webdriver.Chrome(chrome_options=options)


url = "http://centrebet.com/"
driver.get(url)

def page_counter():
  for x in range(1000):
      yield x

count = page_counter()
driver.get(url)
sports = driver.find_element_by_id("accordionMenu1_ulSports")
links = [url + link.get_attribute("onclick").replace("menulink('", "").replace("')", "") for link in sports.find_elements_by_xpath('//ul[@id="accordionMenu1_ulSports"]//li//ul//li//ul//li//a[starts-with(@onclick, "menulink")]')]

links = dict((next(count) + 1, e) for e in links)

desc_links = collections.OrderedDict(sorted(links.items(), reverse=True))
for key, value in desc_links.items():
    driver.get(value)

我尝试过：

logging.disable(logging.CRITICAL)

logging.Logger.info = lambda *args, **kwargs: None

sys.stderr = os.devnull

logging.getLogger("requests").setLevel(logging.WARNING)

@contextmanager
def suppress_stdout():

    with open(os.devnull, "w") as devnull:
        old_stdout = sys.stdout
        sys.stdout = devnull
        try:
            yield
        finally:
            sys.stdout = old_stdout


import warnings

def fxn():
    warnings.warn("deprecated", DeprecationWarning)

with warnings.catch_warnings():
    warnings.simplefilter("ignore")
    fxn()

错误消息似乎循环播放。也许重写可能会解决......

这些日志由Chrome发布。您可以通过启动Chrome并将日志级别设置为致命：

来禁用它们 
options = Options()
options.add_argument('--headless')
options.add_argument('--hide-scrollbars')
options.add_argument('--disable-gpu')
options.add_argument("--log-level=3")  # fatal
driver = webdriver.Chrome(chrome_options=options)

虽然某些邮件未被DevTools listening on ...等标记过滤。

要避免它们，您必须覆盖selenium.webdriver.common.service.Service并使用close_fds=True调用subprocess.Popen以避免继承文件描述符。

self.process = subprocess.Popen(cmd, env=self.env,
                                close_fds=True,
                                stdout=None,
                                stderr=None,
                                stdin=None)

我遇到了类似的问题，以下是我的解决方案。

我在python脚本中使用selenium模块打开chromedriver.exe并自动执行一些在线下载。 我使用BAT文件运行脚本。

最初，如果我运行BAT文件，则打开chrome并下载文件，但命令行挂在日志语句中 DevTools listening on ...

我解决这个问题的方法是在bat文件中添加了行

taskkill /im chromedriver.exe /f

所以我的BAT文件看起来像这样

python python_script.py
taskkill /im chromedriver.exe /f

日志语句仍然出现，但是chromedriver.exe查杀似乎结束了运行。

现在的问题是如何删除错误消息并抑制消息   与chrome驱动程序的关系

要关闭chromedriver日志记录，请使用DesiredCapabilities 

options = Options()
options.add_argument('--headless')
options.add_argument('--hide-scrollbars')
options.add_argument('--disable-gpu')

dc = DesiredCapabilities.CHROME
dc['loggingPrefs'] = {'driver': 'OFF', 'server': 'OFF', 'browser': 'OFF'}

driver = webdriver.Chrome(chrome_options=options, desired_capabilities=dc)

请参阅此处查看possible loggingPrefs values。

答案 3 :(得分：0)

尝试一下：-

options = webdriver.ChromeOptions();
options.add_experimental_option('excludeSwitches',['enable-logging']);

希望有帮助。
