使用 Selenium 修改 Javascript Navigator 对象

Question

我尝试使用 Selenium（使用 geckodriver）访问一个站点，它说我被阻止了，但我可以使用 Firefox 浏览器手动访问它。所以我比较了我的指纹组件，唯一的区别是当我使用 Selenium 时，在 Navigator 对象中“webdriver”设置为“true”。我尝试运行此代码：

from selenium import webdriver

from selenium.webdriver.firefox.options import Options
firefox_binary = '/usr/bin/firefox'
options = Options()
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
caps = DesiredCapabilities().FIREFOX
# caps["pageLoadStrategy"] = "normal"  #  complete
caps["pageLoadStrategy"] = "eager"  #  interactive
injected_javascript=("Object.defineProperty(navigator, 'webdriver', { value: 'false' })")
driver = webdriver.Firefox(executable_path=r'/home/kkkk/ggecko/geckodriver', firefox_binary=firefox_binary)
driver.get('https://auth.citromail.hu/regisztracio/')

driver.execute_async_script(injected_javascript)

但它刚刚加载了“webdriver”仍设置为“true”的页面，然后返回此消息：

Traceback (most recent call last):
  File "/home/kkkk/driverr.py", line 14, in <module>
    driver.execute_async_script(injected_javascript)
  File "/home/kkkk/.local/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 652, in execute_async_script
    'args': converted_args})['value']
  File "/home/kkkk/.local/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 314, in execute
    self.error_handler.check_response(response)
  File "/home/kkkk/.local/lib/python3.5/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message: Timed out

我做错了什么还是有其他方法可以做到这一点？

参考这个问题： Selenium webdriver: firefox headless inject javascript to modify browser property

它提供了一条有用的途径。

这是代码：

import os
from selenium import webdriver
options=webdriver.FirefoxOptions()
options.set_headless(True)
driver=webdriver.Firefox(options=options)
# solution found here https://stackoverflow.com/questions/17385779/how-do-i-load-a-javascript-file-into-the-dom-using-selenium
driver.execute_script("var s=window.document.createElement('script'); s.src='javascriptFirefox.js';window.document.head.appendChild(s);")
driver.get('https://auth.citromail.hu/regisztracio/')

Javascript 文件javascriptFirefox.js

// overwrite the `languages` property to use a custom getter
const setProperty = () => {
    Object.defineProperty(navigator, "languages", {
        get: function() {
            return ["en-US", "en", "es"];
        }
    });

    // Overwrite the `plugins` property to use a custom getter.
    Object.defineProperty(navigator, 'plugins', {
        get: () => [1, 2, 3, 4, 5],
    });

    // Pass the Webdriver test
    Object.defineProperty(navigator, 'webdriver', {
      get: () => false,
    });
    callback();
};
setProperty();
