MSEdgeDriver (Chromium) 不适用于版本 >= 79.0.313 (Canary)

PS: My GetEdgeDriver.BAT which compares the version of currently installed Microsoft Edge (Chromium) Canary browser with currently downloaded webdriver from https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/. If the latter is lower than the former, it downloads the msedgedriver.exe and overwrites the old one.

解决方案

终于解决了我的问题.

1. 安装/升级 Selenium 3.14 到 Selenium 4.0.0a5
2. 将 Python 代码更改为如下所示:

# using edge directly, since you can see 'selenium.webdriver.chromium.webdriver' used in site-packagesseleniumwebdriveredgewebdriver.py
from selenium import webdriver
from selenium.webdriver.edge.options import Options
from selenium.webdriver.edge.service import Service
from selenium.webdriver.edge.webdriver import WebDriver
...
...
driveroptions = Options()
# remember to set use_chromium
driveroptions.use_chromium = True
driveroptions.add_argument('--start-maximized')
driveroptions.binary_location = env_programfiles_x86 + "\Microsoft\Edge\Application\msedge.exe"

service = Service(executable_path="msedgedriver.exe")
driver = webdriver.Edge(options=driveroptions, service=service)

driver.set_page_load_timeout(40)
driver.get(page_url)
