Question

您好我也在使用Hivemq（Windows）并且有问题！

websocket已打开，我收到了一些信息：

`

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＆＃34; mqtt＆＃34; 例如ws：//m2m.eclipse.org:800 / mqtt。 mqtt应该是默认选项，可以选择配置/指定

然而，paho javascript使用的默认路径是＆＃34; / ws＆＃34;

HiveMQ使用＆＃34; / mqtt＆＃34;的默认配置对于websocket的路径

可能的解决方案

将客户端中的路径更改为＆＃34; / mqtt＆＃34;

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

将HiveMQ配置中的路径更改为＆＃34; / ws＆＃34;

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

此致
