嗨，我也在使用 Hivemq (windows) 并且有一个问题！

websocket 已打开，我收到一些信息：

`

但我总是在 chrome 控制台中遇到问题：

`WebSocket connection to 'ws://127.0.0.1:9001/' failed: Connection closed before receiving a handshake response
k._doConnect @ mqttws31-min.js:36
k._disconnected @ mqttws31-min.js:54
k._on_socket_error @ mqttws31-min.js:51
(anonymous) @ mqttws31-min.js:19e

我不是专家请帮忙

根据 Eclipse Paho Wiki

在 MQTT 连接上指定的 url 的路径部分应该是“mqtt”，例如 ws://m2m.eclipse.org:800/mqtt。mqtt 应该是默认的，可以选择配置/指定替代方案

但是 paho javascript 使用的默认路径是“/ws”

HiveMQ 使用“/mqtt”的默认配置作为 websocket 的路径

可能的解决方案是

  • 将客户端中的路径更改为“/mqtt”

    client = new Paho.MQTT.Client("127.0.0.1", Number(9001), "/mqtt", "clientId");

  • 将 HiveMQ 配置中的路径更改为“/ws”

    <websocket-listener>
...
  <path>/ws</path>
...
  </websocket-listener>
