订阅时如何制作mosquitto_sub打印主题和消息#

Question

以下命令显示发布到与正则表达式匹配但不是确切主题本身的主题的所有消息.

mosquitto_sub -h localhost -u user -P pass -t 'devices/#'
{"value":"50"}
{"value":"45"}

例如,上面的json消息发布到主题设备/ 1234/transducer/46364 /但是我无法使用mosquitto_sub打印主题.

Answer 1

使用该-v选项

mosquitto_sub -h localhost -u user -P pass -v -t 'devices/#'

从手册页:

   -v, --verbose
       Print received messages verbosely. With this argument, messages
       will be printed as "topic payload". When this argument is not
       given, the messages are printed as "payload".
