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

问题描述

我在脚本中使用带有 Python3 的 Microsoft Edge Webdriver (Chromium).

I'm using Microsoft Edge Webdriver (Chromium) with Python3 in my script.

webdriver配置如下:

The webdriver configuration is as follows:

driveroptions = Options()
driveroptions.add_argument('--inprivate')
driveroptions.add_argument('--disable-infobars')
driveroptions.add_argument('--start-maximized')
driveroptions.add_argument('--auto-open-devtools-for-tabs')
driveroptions.add_argument('--user-data-dir=D:\Selenium_Edge_Chromium_UserData')
driveroptions.binary_location = "C:\Users\Administrator\AppData\Local\Microsoft\Edge SxS\Application\msedge.exe"
# driver = webdriver.Chrome(options=driveroptions, executable_path="msedgedriver.309.exe", service_log_path="D:\X.txt")
driver = webdriver.Chrome(options=driveroptions, executable_path="msedgedriver.exe", service_log_path="D:\X.txt")

driver.set_page_load_timeout(40)
wait = WebDriverWait(driver, 40)
driver.get(base_url)

之前运行良好，但是从 79.0.313.0 开始，驱动只是返回错误:

It works well previously, but starting with 79.0.313.0, the driver simply returns the error:

Message: session not created: No matching capabilities found

还有这里的服务日志:

如果 msedgedriver 版本保持在 79.0.309.0，我仍然可以使用我的脚本.

I can still use my script if the msedgedriver version is kept at 79.0.309.0.

但是较新版本的 msedgedriver(79.0.313.0、80.0.315.0 等)发生了什么?

But what happened to the newer versions of msedgedriver (79.0.313.0, 80.0.315.0 etc.)?

他们是否放弃了一些支持的功能?

Are they dropping some supported capabilities?

更新:

Microsoft Edge (Chromium): 80.0.315.0
msedgedriver for Microsoft Edge (Chromium): 80.0.315.0
->
Message: session not created: No matching capabilities found

Microsoft Edge (Chromium): 79.0.313.0
msedgedriver for Microsoft Edge (Chromium): 79.0.313.0
->
Message: session not created: No matching capabilities found

Microsoft Edge (Chromium): 79.0.309.0
msedgedriver for Microsoft Edge (Chromium): 79.0.309.0
->
(Works well without issue)

使用 79.0.309.0(及更早版本)的 msedgedriver:

and with 79.0.309.0 (and older) msedgedriver:

Microsoft Edge (Chromium): (version before 79.0.309.0)
msedgedriver for Microsoft Edge (Chromium): (version before 79.0.309.0, = browser version)
->
(Works without issue)

Microsoft Edge (Chromium): 79.0.309.0
msedgedriver for Microsoft Edge (Chromium): 79.0.309.0
->
(Works without issue)

Microsoft Edge (Chromium): 79.0.313.0
msedgedriver for Microsoft Edge (Chromium): 79.0.309.0
->
(Works without issue)

Microsoft Edge (Chromium): 80.0.315.0
msedgedriver for Microsoft Edge (Chromium): 79.0.309.0
->
(Works without issue)

PS:我的 GetEdgeDriver.BAT 将当前安装的 Microsoft Edge (Chromium) Canary 浏览器的版本与当前从 https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/.如果后者低于前者，则下载 msedgedriver.exe 并覆盖旧的.

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.

推荐答案

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)
