WebDriver 与浏览器版本兼容问题

Question

我开发了一个小型应用程序，可以自动执行 Intranet 上的某些任务。为了方便与没有 Python 的用户共享，我将此应用程序导出为可执行文件 (.exe)。该应用程序已经测试了一段时间并且运行正常。

但是，浏览器更新时会出现问题：由于 WebDriver 的版本与默认的 Microsoft Edge 浏览器版本不匹配，导致脚本无法使用。当我尝试通过 IDE 启动脚本时，显示以下错误消息：

> 
> > ```
> SessionNotCreatedException: session not created: This version of Microsoft Edge WebDriver only supports Microsoft Edge version 124
> Current browser version is 123.0.2420.81 with binary path C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe
> > ```

有没有办法自动更新WebDriver，使其与当前浏览器版本匹配？我必须使用 Microsoft Edge 来完成这个项目。

预先感谢您提供的任何帮助或建议。

Answer 1

从 v4.6 开始，Selenium 现在包含一个内置驱动程序管理器，Selenium Manager。您的起始代码可以很简单

from selenium import webdriver

url = "about:blank"
driver = webdriver.Edge()
driver.maximize_window()
driver.get(url)
# do stuff

Selenium 将自动下载匹配的浏览器和版本，配置并在您的脚本中使用它。

运行您建议的代码时，我遇到以下错误消息：

我认为发生此错误是因为 Selenium 无法从网站 https://msedgedriver.azureedge.net/LATEST_RELEASE_123_WINDOWS 自动下载 Microsoft Edge 驱动程序。在我看来，这是因为我需要通过代理（例如：pip --proxy http://vip2.cori.ade.cdm:8080 install selenium），我尝试使用IA建议解决问题但我有同样的问题：

from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType
proxy = Proxy()
proxy.proxy_type = ProxyType.MANUAL
proxy.http_proxy = "http://vip2.cori.ade.cdm:8080"
proxy.ssl_proxy = "http://vip2.cori.ade.cdm:8080"
capabilities = webdriver.DesiredCapabilities.EDGE.copy()
proxy.add_to_capabilities(capabilities)
driver = webdriver.Edge(desired_capabilities=capabilities)
driver.get("https://www.google.com")
