client 向 broker 订阅时 topic 时,指定的是 broker 向 client 下发消息的 QoS。 ClientA -> Broker -> ClientB 上述过程中,就分别有两个 QoS,如果 publish with QoS 2,subscribe with QoS 1, 那么即使 ClientA 只给broker发送了一次消息, ClientB 也有可能收到多条。

确认过用户名、密码和Client ID无误,问题仍未解决,期待回复! 测试是使用的MQTTX工具,通过AccessKey生成对应Client ID的用户名和密码。配置公网接入点和端口1883,点击连接报错。工具截图如下: 用户名和密码、Client ID等都检查了,无法解决,盼复!!!
