使用Python Selenium测试时遇Google Edge Cache禁止错误求助

问题描述 #

运行Python Selenium代码时，ChromeDriverManager自动下载ChromeDriver的请求被Google Edge Cache拦截，返回Google-Edge-Cache: forbidden Error:7，无法完成驱动安装。

运行代码 #

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service

service = Service(executable_path=ChromeDriverManager().install())
driver = webdriver.Chrome(service=service)

错误详情 #

解决方案 #

1. 手动下载ChromeDriver并指定路径 #

• 查看本地Chrome版本：打开Chrome，输入chrome://settings/help获取版本号（示例为116.0.5845.96）
• 下载对应版本的ChromeDriver压缩包，解压得到chromedriver.exe
• 修改代码直接指定驱动路径：

from selenium import webdriver
from selenium.webdriver.chrome.service import Service

# 替换为你解压后的chromedriver实际路径
service = Service(executable_path=r"C:\your\path\to\chromedriver.exe")
driver = webdriver.Chrome(service=service)

2. 给ChromeDriverManager配置国内镜像源 #

用国内镜像绕过Google缓存限制，示例使用淘宝镜像：

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service

service = Service(executable_path=ChromeDriverManager(url="https://npm.taobao.org/mirrors/chromedriver/").install())
driver = webdriver.Chrome(service=service)

需要指定版本时，添加version参数：

ChromeDriverManager(version="116.0.5845.96", url="https://npm.taobao.org/mirrors/chromedriver/").install()

3. 检查网络环境 #

• 切换网络（如手机热点），排查是否是公司防火墙、代理服务器拦截请求
• 若使用代理，确认代理配置可正常访问外部资源
