Python selenium webdriver Chrome - Chrome由自动化软件控制

Question

我正在使用selenium webdriver并创建一个chrome驱动程序实例。当我尝试向下滚动并向上滚动时，我收到以下错误消息。此外，我可以看到错误消息“Chrome正在由自动化软件控制”。虽然我无法在Chrome浏览器中更改任何设置以允许自动化，但很难看到此错误。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait as wait
from selenium.common.exceptions import TimeoutException

from log_util.logger import log as Log

import time

log = Log()


class Wiki(object):
    def __init__(self):
        self.link = 'http://wikipedia.org'
        self.path = '/Users/swadhikar_c/Downloads/chromedriver'
        self.driver = webdriver.Chrome(executable_path=self.path)

    def open_wiki(self):
        driver = self.driver
        driver.get(self.link)
        return self.wait_for_page_load()

    def wait_for_page_load(self, timeout=200):
        is_element_located = EC.presence_of_element_located((By.CLASS_NAME, 'central-featured-logo'))

        try:
            wait(self.driver, timeout=int(timeout)).until(is_element_located)
            print("Page loaded successfully")
            time.sleep(5)
        except TimeoutException:
            print("Operation timed out")
            raise

        return 1

    def scroll_down_up(self):
        driver = self.driver

        element = driver.find_element(By.TAG_NAME, 'html')
        element.send_keys(Keys.END)

        print("Scrolled down to the end!")
        time.sleep(5)

        element.send_keys(Keys.HOME)

        print("Scrolled up to the top!")
        time.sleep(5)

    def close_driver(self):
        self.driver.quit()


if __name__ == '__main__':
    wiki = Wiki()

    try:
        if not wiki.open_wiki():
            print("Operation failed")

        wiki.scroll_down_up()

    finally:
        wiki.close_driver()

我做了一些挖掘并发现它已经解决了。刚刚修改了init函数，如下所示。

from selenium.webdriver.chrome.options import Options

def __init__(self):
    self._link = 'https://in.norton.com/'
    _path = '/Users/swadhikar_c/Downloads/chromedriver'
    _chrome_options = Options()
    _chrome_options.add_argument('disable-infobars')
    self.driver = webdriver.Chrome(executable_path=_path, chrome_options=_chrome_options)
