HiveMQ 2.1.0 + Eclipse javascript mqttws31.js的Websocket连接错误

Question

在Google上执行mqttws31.js作为HTML文件的一部分时，我将面临以下错误。

HiveMQ被用作MQTT代理，日志如下所示

2014-10-28 14:46:45,043 INFO  - HiveMQ home directory: E:\hivemq-2.1.0
2014-10-28 14:46:45,065 INFO  - Starting HiveMQ Server

2014-10-28 14:46:48,734 INFO  - Started HiveMQ 2.1.0 in 3694ms

当包含MQTT客户端的HTML文件时，会遇到以下错误。

WebSocket connection to 'ws://127.0.0.1:1883/mqtt' failed: Connection closed before receiving a handshake response

任何解决这个问题的帮助都很感激。

Answer 1

您似乎没有启用websockets，无法在hivemq中使用mqttws31.js。

请参见此处的设置；options

Open conf/configurations.properties with your favorite editor Change websockets.enabled to true

然后在代码中连接到；ws://127.0.0.1:8000/mqtt

以下是在hivemq‘网站http://www.hivemq.com/hivemq-mqtt-websockets-support-message-log-plugin-2-min/上的快速操作
