訂閱時如何制作mosquitto_sub打印主題和消息＃

Question

以下命令顯示發布到與正則表達式匹配但不是確切主題本身的主題的所有消息。

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

例如，上面的json消息發布到主題設備/ 1234 / transducer / 46364 /但是我無法使用mosquitto_sub打印主題。

Answer 1

使用-v選項

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

從手冊頁：

   -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".
