用硒Python驱动器Opera [英] Drive Opera with selenium python

问题描述

我已添加到环境变量

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

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

Python脚本:

from selenium import webdriver

webdriver.Opera()

输出:

我期望jar已定义了所有内容，为什么找不到驱动程序类?

I was expecting jar to have everything defined, why do I get Driver class not found?

推荐答案

根据您的问题，您似乎正在使用适用于Opera 12及更高版本的旧驱动程序.假设您尝试使用最新版本的Opera，则要使用以下站点上提供的驱动程序: OperaChromiumDriver

Based on your question it looks like you are using an old driver for Opera version 12 and older. Assuming that you're trying to use the most recent version of Opera you'll want to use the driver available at the following site: OperaChromiumDriver

该站点列出了我已确认可在我的机器上打开并驱动Opera的示例python代码:

The site lists sample python code which I have confirmed works on my machine to open and drive 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()

查看硒的更改日志，似乎在2.45之后不再支持基于Presto的Operas，这就是为什么您收到错误消息的原因:

Looking into the change logs for selenium it looks like support for Presto-based Operas was discontinued after 2.45 which is why you're getting the error messages:CHANGELOG
