带有IoT中心的Azure功能触发获取发送设备

Question

我使用IoT中心触发器创建了一个功能

log.Info($"C# IoT Hub trigger function processed a message: {Encoding.UTF8.GetString(message.GetBytes())}");

该功能仅记录消息。但是我如何获得发送消息的设备？

看看下面的例子：

using System;

public static void Run(string myIoTHubMessage, IDictionary<string, object> properties, IDictionary<string, object> systemproperties, TraceWriter log)
{
    log.Info($"C# IoT Hub trigger function processed a message: \n\t{myIoTHubMessage}");

    log.Info($"DeviceId = {systemproperties["iothub-connection-device-id"]}");

    log.Info($"\nSystemProperties:\n\t{string.Join("\n\t", systemproperties.Select(i => $"{i.Key}={i.Value}"))}");

    log.Info($"\nProperties:\n\t{string.Join("\n\t", properties.Select(i => $"{i.Key}={i.Value}"))}");
}
