Mosquitto - disable subscription with wildcards

Question

我想使用通配符（ +和＃ ）禁用所有主题的订阅，这可能吗？

Answer 1

Yes, on a per user basis. You can use the ACL to limit what topics a given user can subscribe to and these can include wildcards. Details of the ACL format can be found in the mosquitto.conf man page here

You can also prevent anonymous users being able to connect to the broker at all.
