我是物联网新手。我刚刚在我的 rpi 上安装了 mosquitto，并使用本教程在 Watson IoT Platform 中注册了我的设备和网关：https ://developer.ibm.com/recipes/tutorials/using-mosquitto-as-a-gateway-for-watson-iot /
Mosquitto 在本地模式下工作正常。但是，我在使用这些命令订阅/发布时遇到问题：
mosquitto_sub -d -h pxci52.messaging.internetofthings.ibmcloud.com -i 'g:pxci52:myfstream:gateway' -t iot-2/type/myfstream/id/gateway/evt/status/fmt/raw
和
sudo mosquitto_pub -d -h pxci52.messaging.internetofthings.ibmcloud.com -i 'g:pxci52:myfstream:gateway' -t iot-2/type/myfstream/id/gateway/evt/status/fmt/raw -m "hello"
这是我的conf文件：

log_dest topic
log_type error
log_type warning
log_type notice
