我服务器使用的是moquette,里面的nettyAcceptor已经明确说明了TCP和websocket的不同处理,可以看到代码中websocket是关闭的: private void initializePlainTCPTransport(final NettyMQTTHandler handler, IConfig props) throws IOException { final MoquetteIdleTimeoutHandler timeoutHandler = new MoquetteIdleTimeoutHandler();...
Adjusting network parameters: You can improve network performance by modifying the operating system's network parameters. For example, you can use the sysctl command to set TCP connection parameters, which will increase the system's ability to handle TCP connections. Adjusting memory parameters: You ...
In Linux, you can use tcpdump to capture the packets and then import them to Wireshark for viewing. The following command will create a client connection with the Client ID mqtt-892324. In order to avoid repeating the Client ID with others, it is recommended to change it to another ...

握手完成后，客户端发送一个MQTT连接数据包。当您使用以MQTT 5作为协议版本的HiveMQ客户端时，这将包含一个期望MQTT 5的标志。现在，如果使用的代理不能处理这个问题，它将关闭连接(协议错误)。

The address of the server should be a URI, using a scheme of either "tcp://" for a TCP connection or "ssl://" for a TCP connection secured by SSL/TLS. For example: tcp://localhost:1883 ssl://localhost:8883 If the port is not specified, it will default to 1883 for "...
