使用Selenium修改Javascript Navigator对象 [英] Modifying the Javascript Navigator object with Selenium

问题描述

我尝试使用Selenium（使用geckodriver）访问网站，它说我被阻止但我可以使用Firefox浏览器手动访问它。所以我比较了我的fingerpirnt的组件，唯一的区别是当我使用Selenium时，在Navigator对象中webdriver被设置为true。我尝试从selenium导入webdriver

来自selenium.webdriver.firefox.options导入选项
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
inject_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（inject_javascript）

但它只是加载了webdriver仍然设置为true的页面，然后返回此消息：

 回溯（最近一次调用最后一次）：
文件/home/kkkk/driverr.py，第14行，< module> 
 driver.execute_async_script（inject_javascript）
文件/home/kkkk/.local/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py，第652行，在execute_async_script中
'args'：converted_args}）['value'] 
文件/home/kkkk/.local/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py ，第314行，执行
 self.error_handler.check_response（response）
 File/home/kkkk/.local/lib/python3.5/site-packages/selenium/webdriver/remote/errorhandler。 py，第242行，在check_response中
引发exception_class（消息，屏幕，堆栈跟踪）
 selenium.common.exceptions.TimeoutException：消息：超时
  

我做错了什么或有不同的方法来实现这个目标？

解决方案

请参阅此问题：
SEL enium webdriver：firefox headless注入javascript来修改浏览器属性

它提供了一个有用的途径。

这是代码：

 从selenium import webdriver导入os 
 
 options = webdriver.FirefoxOptions（ ）
 options.set_headless（True）
 driver = webdriver.Firefox（options = options）
＃solution here 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

  //覆盖`languages`属性以使用自定义getter 
 const setProperty =（）=> {
 Object.defineProperty （navigator，languages，{
 get：function（）{
 return [en-US，en，es]; 
} 
}） ; 
 
 //覆盖`plugins`属性以使用自定义getter。
 Object.defineProperty（navigator，'plugins'，{
 get :(）=> [ 1,2,3,4,5]，
}）; 
 
 //传递Webdriver测试
 Object.defineProperty（navigator，'webdriver'，{
 get：（）=> false，
}）; 
 callback（）; 
}; 
 setProperty（）; 
  

I tried accessing a site with Selenium (with geckodriver) and it said I was blocked but I can access it manually with the Firefox Browser. So I compared the components of my fingerpirnt and the only difference was that in the Navigator object "webdriver" was set to "true" when I used Selenium. I tried running this code:

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)

but it just loaded page with "webdriver" still set to "true", then returned this message:

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

What am I doing wrong or is there a different way of accomplishing this?

解决方案

Refer to this issue: Selenium webdriver: firefox headless inject javascript to modify browser property

it provides a useful pathway.

This is the code:

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 file 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();
