Selenium Python设置options.platform_name报错：无匹配会话功能

环境版本信息 #

• chromedriver版本：125.0.6422.141 (r1287751) (64位)
• Chrome版本：125.0.6422.142 (官方版本) (64位)
• Selenium版本：4.21.0

相关代码 #

from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
import time

options = webdriver.ChromeOptions()
options.add_argument("--disable-blink-features=AutomationControlled")
options.platform_name = 'Windows 10'
service = ChromeService(executable_path=r'C:\Users\rr\Desktop\TL\chromedriver.exe')

browser = webdriver.Chrome(options=options)
browser.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Android; Android 4.4.1; LG-F500L Build/KOT49H) AppleWebKit/601.44 (KHTML, like Gecko)  Chrome/54.0.3656.325 Mobile Safari/602.8'})
browser.set_window_size(393, 851)
url = "https://www.google.com/"
browser.get(url)

问题现象 #

• 删掉代码里的options.platform_name = 'Windows 10'，程序能正常运行
• 加上这句话后，直接抛出错误：

Message=Message: session not created: No matching capabilities found

原因分析 #

Selenium 4+遵循W3C规范，platform_name属于会话能力的严格匹配项。你手动指定了Windows 10平台，但同时通过CDP设置了Android设备的User-Agent，两者平台属性冲突，ChromeDriver找不到同时满足这两个条件的会话，因此抛出错误。

解决方法 #

方案1：移除手动指定的platform_name #

Selenium会自动检测当前运行的系统平台，完全不需要手动设置platform_name，删掉这行代码即可恢复正常。

方案2：保证平台与User-Agent一致 #

如果确实需要设置平台信息，必须让platform_name和User-Agent的平台属性匹配：

• 若要保留Android的User-Agent，将platform_name改为"Android"
• 若要使用Windows 10平台，需把User-Agent替换为Windows版本的（比如Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36）

示例代码（保留Android UA的修改版）：

from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
import time

options = webdriver.ChromeOptions()
options.add_argument("--disable-blink-features=AutomationControlled")
options.platform_name = 'Android'  # 与UA平台匹配
service = ChromeService(executable_path=r'C:\Users\rr\Desktop\TL\chromedriver.exe')

browser = webdriver.Chrome(options=options)
browser.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Android; Android 4.4.1; LG-F500L Build/KOT49H) AppleWebKit/601.44 (KHTML, like Gecko)  Chrome/54.0.3656.325 Mobile Safari/602.8'})
browser.set_window_size(393, 851)
url = "https://www.google.com/"
browser.get(url)
