用 selenium 驱动 Opera python

Question

我添加到我的环境变量

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：

我原以为 jar 已经定义了所有内容，为什么我找不到驱动程序 class？

Answer 1

根据您的问题，您使用的似乎是适用于 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

该站点列出了示例 python 代码，我已经确认它可以在我的机器上打开和驱动 Opera：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，看起来对基于 Presto 的 Operas 的支持在 2.45 之后停止，这就是您收到错误消息的原因：CHANGELOG

下面的代码适用于我的以下设置。希望这有帮助。

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 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 ... 如上所述它将打开 Opera 浏览器... 而不是 chrome 浏览器

您可以在这里下载 Opera 驱动程序：https://github.com/operasoftware/operachromiumdriver

Answer 4

我用 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())

使用：

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