运行Python移动自动化脚本遇Selenium授权错误求助

运行DriverScript.py时触发selenium.common.exceptions.WebDriverException: Message: Authorization required错误，完整报错堆栈如下：

PS C:\Users\Shibin.R\Downloads\retail-east-connectedcustomer-main\retail-east-connectedcustomer-main> python DriverScript.py

已确认所有依赖包安装完成，问题仍未解决。

解决步骤 #

• 检查Appium Server的认证配置
  如果Appium Server启用了基础认证，初始化webdriver.Remote时需传入认证信息。修改GenericFunctions.py中初始化driver的代码：

  from base64 import b64encode
  
  # 替换为实际的Appium认证账号密码
  username = "your_appium_username"
  password = "your_appium_password"
  auth_str = b64encode(f"{username}:{password}".encode()).decode()
  
  # 初始化driver时添加认证请求头
  self.driver = webdriver.Remote(
      command_executor="http://your_appium_server:4723/wd/hub",
      desired_capabilities=your_capabilities,
      headers={"Authorization": f"Basic {auth_str}"}
  )
  

• 关闭Appium Server的不必要认证
  若测试环境不需要认证，重新启动Appium Server时移除--username和--password参数：

  appium --port 4723
  

• 排查网络代理/防火墙限制
  确认脚本运行环境的代理未拦截Appium Server请求，或将Appium Server地址加入代理白名单；同时检查本地防火墙是否允许脚本访问Appium的监听端口（默认4723）。

• 验证版本兼容性
  确保Appium Python Client与Selenium版本匹配，比如Selenium 4.x对应Appium Python Client 2.x及以上。可重新安装指定版本：

  pip uninstall appium-python-client selenium
  pip install appium-python-client==2.11.0 selenium==4.15.2
  

• 检查设备调试权限
  真机测试时，确认设备已授权电脑进行USB调试（在设备上确认"允许USB调试"弹窗）；模拟器测试时，确认模拟器正常启动且端口未被占用，执行adb devices验证设备连接状态。
