使用 selenium python 驱动 Opera

Question

我添加到我的环境变量中

SELENIUM_SERVER_JAR = C:\selenium_drivers\selenium-server-standalone.jar

我在这里下载的 http://selenium-release.storage.googleapis.com/index.html?path=2.46/

Python 脚本：

from selenium import webdriver

webdriver.Opera()

输出：

我希望 jar 定义所有内容，为什么找不到 Driver 类？

Answer 1

下面的代码在以下设置中对我有用。希望这会有所帮助。

• Python：3.4.0
• 歌剧：42.0.2393.94
• 硒：3.0.2

• Chrome 驱动程序：2.27.440174

  import os
  
  from selenium import webdriver
  from selenium.webdriver.common import desired_capabilities
  from selenium.webdriver.opera import options
  
  _operaDriverLoc = os.path.abspath('E:\\Envs\\PySelEnv\\selserver\\chromedriver.exe')  # Replace this path with the actual path on your machine.
  _operaExeLoc = os.path.abspath('E:\\Program Files\\Opera\\42.0.2393.94\\opera.exe')   # Replace this path with the actual path on your machine.
  
  _remoteExecutor = 'http://127.0.0.1:9515'
  _operaCaps = desired_capabilities.DesiredCapabilities.OPERA.copy()
  
  _operaOpts = options.ChromeOptions()
  _operaOpts._binary_location = _operaExeLoc
  
  # Use the below argument if you want the Opera browser to be in the maximized state when launching. 
  # The full list of supported arguments can be found on http://peter.sh/experiments/chromium-command-line-switches/
  _operaOpts.add_argument('--start-maximized')   
  
  self._browserDriver = webdriver.Chrome(executable_path = _operaDriverLoc, chrome_options = _operaOpts, desired_capabilities = _operaCaps)
  

Answer 2

根据您的问题，您似乎正在使用 Opera 12 及更早版本的旧驱动程序。假设您尝试使用最新版本的 Opera，您需要使用以下站点提供的驱动程序：OperaChromiumDriver

该站点列出了我已经确认可以在我的机器上打开和驱动 Opera 的示例 python 代码：Python Examples for OperaChromiumDriver

import time

from selenium import webdriver
from selenium.webdriver.chrome import service


webdriver_service = service.Service('C:\\Users\\Kris\\Downloads\\WinPython-32bit-2.7.9.2\\operadriver.exe')
webdriver_service.start()

driver = webdriver.Remote(webdriver_service.service_url, webdriver.DesiredCapabilities.OPERA)

driver.get('https://www.google.com/')
input_txt = driver.find_element_by_name('q')
input_txt.send_keys('operadriver\n')

time.sleep(5) #see the result
driver.quit()

编辑： 查看 selenium 的更改日志，似乎在 2.45 之后停止了对基于 Presto 的 Operas 的支持，这就是您收到错误消息的原因：CHANGELOG

Answer 3

from selenium import webdriver

driver=webdriver.Chrome('C:\\Users\\abc\\Projects\\TestProject\\operadriver.exe')

driver.get('https://www.google.com/')

/*

只需给出operadriver.exe的位置...如上它将打开Opera浏览器...而不是chrome浏览器

你可以在这里下载opera驱动：https://github.com/operasoftware/operachromiumdriver

Answer 4

我使用webdriver_manager package 用 selenium 驱动 Opera。

安装：

pip install webdriver-manager

设置：

from selenium import webdriver
from webdriver_manager.opera import OperaDriverManager

driver = webdriver.Opera(executable_path=OperaDriverManager().install())

用途：

driver.get("https://www.google.com")
