Rabbitmq 没有从 Paho js 客户端连接

Question

这是我的 paho javascript 客户端代码

  client = new Paho.MQTT.Client(host, Number(port), clientId);

  client.onMessageArrived = onMessageArrived;
  client.onMessageDelivered = onMessageDelivered;
  client.onConnectionLost = onConnectionLost;

这里 port 8083 可以与其他代理一起使用，但不能与 Rabbitmq 一起使用。在文档中我找不到任何正确的端口号。

运行 sudo rabbitmqctl status 给出

  [{rabbitmq_management,"RabbitMQ Management Console","3.6.2"},
      {rabbitmq_web_dispatch,"RabbitMQ Web Dispatcher","3.6.2"},
      {webmachine,"webmachine","1.10.3"},
      {mochiweb,"MochiMedia Web Server","2.13.1"},
      {rabbitmq_mqtt,"RabbitMQ MQTT Adapter","3.6.2"},
 {listeners,[{clustering,25672,"::"},{amqp,5672,"::"},{mqtt,1883,"::"}]},

所以我也尝试使用端口 1883。我正在关注 https://github.com/rabbitmq/rabbitmq-web-mqtt-examples/blob/master/priv/echo.html

我收到此错误：

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

正如评论中所讨论的那样：

Rabbitmq 需要以下插件来支持基于 websockets 的 MQTT (http://github.com/rabbitmq/rabbitmq-web-mqtt)
