MSEdgeDriver（Chromium）在版本79.0.309.0之后不起作用

我在脚本中使用了Microsoft Edge Webdriver（Chromium）和Python3。

webdriver配置如下：

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)

自从我第一次使用Canary以来，它运行良好，但是在79.0.309.0版（不包括在内）之后，驱动程序只是返回错误：

Message: session not created: No matching capabilities found

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

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

他们放弃一些受支持的功能吗？

已更新：

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)

以及79.0.309.0（及更低版本）的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，它将当前安装的Microsoft Edge（Chromium）Canary浏览器的版本与从https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/下载的当前webdriver进行比较。如果后者低于前者，则会下载msedgedriver.exe并覆盖旧的。

我尝试了以下功能，它起作用了，您可以尝试一下：

{
    "desiredCapabilities": {
            "nativeEvents": false,
            "browserName": "chrome",
            "version": "",
            "platform": "ANY",
            "javascriptEnabled": true,
            ...
    }
}

浏览器和Webdriver必须与版本号的前3个元组匹配。

在chrome中，有一个版本检查，可告诉您浏览器和webdriver是否不匹配。 msedge提供了更多的分散性：No matching capabilities found

我使用的是巧克力Microsoft Edge Insider - Beta，它安装了msedge浏览器，当前版本为79.0.309.65。

这意味着我不能使用当前为79.0.313.0的最新的79.x msedgedriver，我必须使用79.0.309.x。

我已经在selenium驱动程序中实现了一个简单的测试，可以在开始之前进行检查。

最终解决了我的问题。

  1. 将Selenium 3.14安装/升级到Selenium 4.0.0a5
  2. 将Python代码更改为以下内容：
# using edge directly, since you can see 'selenium.webdriver.chromium.webdriver' used in site-packages\selenium\webdriver\edge\webdriver.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)
