我找不到应该复制设备证书的位置。可能是我的理解是错误的。帮我纠正它。

谢谢， Sreeju

您是否像在previous step中提到的那样使用Visual Studio来构建项目？如果是这样，VS应该会为您连接，这样您就不必在一端复制证书，只需使用该证书在AzIotHub一侧设置设备即可。

要解决为什么没有发生这种情况，可以添加或链接自己构建的provisioning_device_client_sample.py文件吗？它可能显示或指向X509SecurityClient类的实例化位置，这将导致X509对象，该对象的属性（self._cert_file）将显示文件路径。如果您可以在python IDE中运行它，也可以帮助我们在控制台上进行加载。

如果这样做不方便，我可以自己构建SDK /示例并运行它，但是我已经很长时间没有在VM上打开Visual Studio了，可能可能需要经过一些许可协议。（我主要使用不需要构建较新版本的IOTHub设备和服务SDK，或者使用SDK可能无法使用的区域的REST api。）在我有一些空闲时间之前，需要花费一些时间。那。

“自动配置模拟设备（python）”快速入门指南中的iot-device使用X509证书吗？
