索取所有已发布的主题 [英] Request all published topics

问题描述

我正在为我的MQTT经纪人使用蚊子.

I'm using Mosquitto for my MQTT Broker.

我想知道是否可以请求所有已发布的主题?

I was wondering if it would be possible to request all published topics?

因此不能通过订阅所有内容，即#.

Thus NOT by subscribing to everything, i.e. #.

我不想订阅每个可用的主题.我只是在寻找一种检索所有已发布主题的方法.例如，代理可以使用包含所有已发布主题的字符串数组进行响应.

I don't want to subscribe to every available topic. I'm just looking for a way to retrieve all published topics. The broker could for instance response with a string array containing all the published topics.

推荐答案

MQTT代理的可管理性目前还很不成熟. 我也不知道从任何经纪人那里检索已发布主题列表的方法. 但是，有一些标准化工作，例如.与$ SYS主题树 https://github.com/mqtt/mqtt.github.io/wiki/SYS-Topics .

Manageability of MQTT brokers is very immature at this point. I also don't know of a way to retrieve the list of published topics from any broker. But, there are standardization efforts, eg. with the $SYS topic tree https://github.com/mqtt/mqtt.github.io/wiki/SYS-Topics.

其他代理可以通过SNMP管理，例如. MessageSight https://www.ibm.com/support/knowledgecenter/zh-CN/SSCGGQ_1.2.0/com.ibm.ism.doc/Monitoring/admin00008_.html .它可以在其WEB界面中列出主题，但我不知道以编程方式检索主题的方法.

Other brokers are manageable via SNMP, eg. MessageSight https://www.ibm.com/support/knowledgecenter/en/SSCGGQ_1.2.0/com.ibm.ism.doc/Monitoring/admin00008_.html . It can list the topics in its WEB interface, but I don't know of a programmatic way to retrieve them.
