添加以下功能，当设备从IoT Hub接收到SetTemperature和SetHumidity命令时执行：

EXECUTE_COMMAND_RESULT SetTemperature(Thermostat* thermostat, int temperature)
{
(void)printf("Received temperature %drn", temperature);
thermostat->Temperature = temperature;
return EXECUTE_COMMAND_SUCCESS;
}
EXECUTE_COMMAND_RESULT SetHumidity(Thermostat* thermostat, int humidity)
{
(void)printf("Received humidity %drn", humidity);
thermostat->Humidity = humidity;
return EXECUTE_COMMAND_SUCCESS;
}

添加以下向IoT集线器发送消息的功能：

static void sendMessage(IOTHUB_CLIENT_HANDLE iotHubClientHandle, const unsigned char* buffer, size_t size)
{
IOTHUB_MESSAGE_HANDLE messageHandle = IoTHubMessage_CreateFromByteArray(buffer, size);
if (messageHandle == NULL)
{
printf("unable to create a new IoTHubMessagern");
}
else
{
if (IoTHubClient_SendEventAsync(iotHubClientHandle, messageHandle, NULL, NULL) != IOTHUB_CLIENT_OK)
{
printf("failed to hand over the message to IoTHubClient");
}
else
{
printf("IoTHubClient accepted the message for deliveryrn");
}
IoTHubMessage_Destroy(messageHandle);
}
free((void*)buffer);
}
