client.js

var device = { nickname: 'wbk0da8v9l2wewmi', secret: 'mysecret' };



var msg  = 'devices/' + device.nickname + '/msg' ;

var mqtt = require('mqtt');

console.log(msg);


var client = mqtt.connect('mqtt://localhost:1883',{  username: device.nickname,  password: device.secret   });

client.subscribe(msg);

client.on('connect', function() {
    console.log('Client successfully connected');
    client.on('message', function(topic, message) {
        console.log('received from', topic, message);
        client.publish(msg, 'Client 1 is alive.. Test Ping msg! ' + Date());
        client.end();
    });
});

工作正常。

但是如果我在远程服务器上有代理和client.html 使用

将client.js留在我的localhost上

var device = { nickname: 'wbk0da8v9l2wewmi', secret: 'mysecret' };



var msg  = 'devices/' + device.nickname + '/msg' ;

var mqtt = require('mqtt');

console.log(msg);


var client = mqtt.connect('mqtt://204.151.191.103:1883',{  username: device.nickname,  password: device.secret   });

client.subscribe(msg);

client.on('connect', function() {
    console.log('Client successfully connected');
    client.on('message', function(topic, message) {
        console.log('received from', topic, message);
        client.publish(msg, 'Client 1 is alive.. Test Ping msg! ' + Date());
        client.end();
    });
});

它没有用。

我想知道问题是什么？我做错了什么？

更新

当我说它没有工作时，我的意思是

我可以看到

客户端已成功连接

从控制台窗口（当我运行client.js时）

但是我无法看到客户端的任何消息

收到

（on message事件未被触发）

和浏览器端

我的留言

（on message事件未被触发）

当我在firebug控制台中运行client.html时，我已经

了

Firefox无法在ws：//myserver.me：3000 /建立与服务器的连接。

Answer 1

在client.html上你是否还更改了主机：＆＃39; localhost＆＃39;，端口：3000用于远程主机？

您是否与另一个MQTT客户端（如MQTT.fx或mosquitto_pub）成功连接到204.151.191.103端口1883？

MQTT-over-Websockets在远程服务器上运行

client.html

client.js
