如何通过 Azure REST API 获取物联网边缘模块的 运行 状态？ （不是来自 'Get Modules on Device' API 调用的连接状态或状态）

Question

上下文：

Azure REST - Modules - Get Modules On Device

通过使用此 API 调用，我可以获得有关模块的连接状态 (connected/disconnected) 和状态 (enalbled/disabled) 的信息。我们可以通过访问 Azure Iot Hub 门户网站来检查部署在设备上的模块的运行时状态 portal.azure.com -> iot hub -> iot edge section -> select the device you wish to find the details for

问题： 如何通过 Azure API 获取此 RUNTIME STATUS？（请参考图片）。

Answer 1

如果检查 edgeAgent 的模块孪生，如下所示：-

        }
      }
    }
  }
}

在上面的json中，CustomModuleName是自定义模块，它有一个名为runtimeStatus: "running"的字段。 edgeHub 和 edgeAgent 模块中也存在相同的字段。因此，您只需通过 REST API 或 Azure Device/Service sdk.
