如何覆盖默认设置的chrome命令行开关在硒



默认情况下,chrome将使用以下命令行运行:

"C:Program Files (x86)GoogleChromeApplicationchrome.exe"
--disable-hang-monitor
--disable-prompt-on-repost
--dom-automation
--full-memory-crash-report
--no-default-browser-check
--no-first-run
--disable-background-networking
--disable-sync
--disable-translate
--disable-web-resources
--safebrowsing-disable-auto-update
--safebrowsing-disable-download-protection
--disable-client-side-phishing-detection
--disable-component-update
--disable-default-apps
--enable-logging
--log-level=1
--ignore-certificate-errors
--no-default-browser-check
--test-type=ui
--user-data-dir="C:UsersnikAppDataLocalTempscoped_dir1972_4232"
--testing-channel=ChromeTestingInterface:1972.1
--noerrdialogs
--metrics-recording-only
--enable-logging
--disable-zero-browsers-open-for-tests
--allow-file-access
--allow-file-access-from-files about:blank

我需要重写(删除)所有命令--disable-*,因为没有等效的命令--enable-*

最后,我想用下面的命令行运行浏览器:

"C:Program Files (x86)GoogleChromeApplicationchrome.exe"    
--dom-automation
--full-memory-crash-report
--no-first-run
--safebrowsing-disable-auto-update
--safebrowsing-disable-download-protection
--enable-logging
--log-level=1
--ignore-certificate-errors
--test-type=ui
--user-data-dir="C:UsersnikAppDataLocalTempscoped_dir1972_4232"
--testing-channel=ChromeTestingInterface:1972.1
--noerrdialogs
--metrics-recording-only
--enable-logging
--allow-file-access
--allow-file-access-from-files about:blank

例如,我尝试运行带有翻译信息栏的浏览器。我找到了--enable-translate选项

capabilities = DesiredCapabilities.CHROME.copy()
capabilities['chrome.switches'] = ['--enable-translate']

但这没有帮助,信息栏没有出现。在命令行中有两个命令:--disable-translate--enable-translate。这是因为有必要删除命令--disable-default-apps

假设您想在Python中这样做,您可以向chromeOptions添加一个参数,以便它不会启用这些开关(有点令人困惑,但没关系)。

假设您想要删除以下开关:

--disable-hang-monitor
--disable-prompt-on-repost
--disable-background-networking
--disable-sync
--disable-translate
--disable-web-resources
--disable-client-side-phishing-detection
--disable-component-update
--disable-default-apps
--disable-zero-browsers-open-for-tests

你可以这样设置你的Chrome驱动程序:

from selenium import webdriver
chromeOptions = webdriver.ChromeOptions()
chromeOptions.add_experimental_option(
    'excludeSwitches',
    ['disable-hang-monitor',
     'disable-prompt-on-repost',
     'disable-background-networking',
     'disable-sync',
     'disable-translate',
     'disable-web-resources',
     'disable-client-side-phishing-detection',
     'disable-component-update',
     'disable-default-apps',
     'disable-zero-browsers-open-for-tests'])
chromeDriver = webdriver.Chrome(chrome_options=chromeOptions)

您应该自己启动浏览器,然后告诉selenium您已经通过传递特殊通道id启动了浏览器。像这样:

from random import randrange
channel_id = "%032x" % randrange(16**32)
from subprocess import Popen
# HERE YOU PASS ONLY THOSE PARAMETERS YOU WANT (i.e. without --disable-*)
# BUT YOU MAY NEED --dom-automation FOR SOME ROUTINES
chrome = Popen(" ".join([
    PATH_TO_CHROME_EXE,
    "--no-first-run", "--dom-automation",
    ("--testing-channel="NamedTestingInterface:%s"" % channel_id),
]))
try:
    from selenium.webdriver.chrome.service import Service
    chromedriver_server = Service(PATH_TO_CHROMEDRIVER, 0)
    chromedriver_server.start()
    from selenium.webdriver import Remote
    driver = Remote(chromedriver_server.service_url,
        {"chrome.channel": channel_id, "chrome.noWebsiteTestingDefaults": True})
    driver.get(MY_WEBPAGE)
    # DO YOUR WORK
finally:
    chromedriver_server.stop()
    driver.quit()
chrome.kill()
chrome.wait()

现在你可以直接使用excludeSwitches属性了

   desiredCapabilities: {
        browserName: 'chrome',
        chromeOptions: {
            args: [],
            excludeSwitches: [ "disable-background-networking" ]
        }
    }

注意没有"——"

从selenium中定制Chrome选项的官方方式:

    # renaming import in order to avoid collision with Options for other browsers, so that you can also use e.g.
    # from selenium.webdriver.firefox.options import Options as FirefoxOptions
    from selenium.webdriver.chrome.options import Options as ChromeOptions

    options = ChromeOptions()
    options.add_argument("--headless")
    options.add_argument('--disable-gpu')
    options.add_argument('--disable-dev-shm-usage')
    options.add_argument('--disable-extensions')
    options.add_argument('--no-sandbox')
    options.add_argument('window-size=1920,1080')
    # only necessary if you want to use a specific binary location
    # options.binary_location = '/Applications/Chromium.app/Contents/MacOS/Chromium'
    driver = webdriver.Chrome(chrome_options=options)

我试着遵循Nakilions的答案(https://stackoverflow.com/a/17429599/4240654):

import subprocess 
chrome = subprocess.Popen(["/opt/google/chrome/chrome", "--no-first-run", "--dom-automation", "--testing-channel=NamedTestingInterface:e7379994e192097cde140d3ffd949c92"],  cwd="/")
from selenium.webdriver.chrome.service import Service
chromedriver_server = Service('/usr/lib/chromium-browser/chromedriver', 0)
chromedriver_server.start()
from selenium.webdriver import Remote
driver = Remote(chromedriver_server.service_url,
    {"chrome.channel": 'e7379994e192097cde140d3ffd949c92', "chrome.noWebsiteTestingDefaults": True})

我在Python解释器中运行这一切。Chromedriver窗口打开,但没有显示"同步"帐户和图标。这对我来说是必要的,因为我试图在谷歌语音信息上运行一个脚本来删除,所以我必须登录。

我也尝试了两个标志方法:

from selenium import webdriver
chromeOptions = webdriver.ChromeOptions()
chromeOptions.add_experimental_option(
    'excludeSwitches',
    ['disable-hang-monitor',
     'dom-automation',
     'full-memory-crash-report',
     'no-default-browser-check',
     'no-first-run',
     'safebrowsing-disable-auto-update',
     'safebrowsing-disable-download-protection',
     'disable-component-update',
     'enable-logging',
     'log-level=1',
     'ignore-certificate-errors',
     'disable-prompt-on-repost',
     'disable-background-networking',
     'disable-sync',
     'disable-translate',
     'disable-web-resources',
     'disable-client-side-phishing-detection',
     'disable-component-update',
     'disable-default-apps',
     'disable-zero-browsers-open-for-tests'])
chromeDriver = webdriver.Chrome(chrome_options=chromeOptions)
chromeDriver.get("https://www.google.com/voice/b/1?gsessionid=adebrtbrt&pli=1#inbox/p89")
