问题描述
是否可以通过mqtt将消息发送给天蓝色的任何自定义主题.到目前为止，我发现的所有示例都适用于标准主题
Is it possible to send messages to azure to any custom topic via mqtt. All example that I've found so far work with standard topics
'devices/' + hubName + '/messages/events/'
'devices/' + hubName + '/messages/devicebound/#'
顺便说一句，尽管连接成功，我还是尝试通过MQTT.fx应用程序发送/订阅上面的主题/订阅，并且从未收到消息.
Btw, I tried to send/subscribe on the topic/subscription above with MQTT.fx application and never received messages, although the connection was successful.
推荐答案
devices/{device_id}/messages/devicebound/#的主题过滤器是订阅从IoT中心接收消息(云到设备消息)，它认为您需要了解以下区别:来自此处.devices/{device_id}/messages/events/的主题是用于从设备发送设备到云的消息.
The topic filter of devices/{device_id}/messages/devicebound/# is to subscribe receiving message from IoT Hub(Cloud-To-Device message), it think you need to understand the difference about device-to-cloud message and cloud-to-device message from here.The topic of devices/{device_id}/messages/events/ is for sending a device-to-cloud message from device.
您可以使用设备浏览器测试这个问题.当您使用该工具向设备发送消息时，MQTT.fx将收到消息.
You can use Device Explorer to test this issue. When you send a message to device with the tool, MQTT.fx will receive the message.
