我正在开发一个物联网项目。我将使用Mqtt来进行设备之间的通信,我开始使用NodeJs和mosca运行一个简单的例子,它在我的本地linux机器上运行。Mqtt Node Js部署在heroku崩溃上
当我开始在Heroku上部署时,遇到了崩溃问题。
这里是我的代码:
var mosca = require('mosca')
var http = require('http');
var url = require('url');
var sys = require('sys');
var settings = {
port: 1883 || Number(process.env.PORT)
};
//here we start mosca
var server = new mosca.Server(settings);
server.on('ready', setup);
// fired when the mqtt server is ready
function setup() {
console.log('Mosca server is up and running')
}
// fired whena client is connected
server.on('clientConnected', function(client) {
console.log('client connected', client.id);
});
// fired when a message is received
server.on('published', function(packet, client) {
console.log('Published : ', packet.payload);
});
// fired when a client subscribes to a topic
server.on('subscribed', function(topic, client) {
console.log('subscribed : ', topic);
});
// fired when a client subscribes to a topic
server.on('unsubscribed', function(topic, client) {
console.log('unsubscribed : ', topic);
});
// fired when a client is disconnecting
server.on('clientDisconnecting', function(client) {
console.log('clientDisconnecting : ', client.id);
});
// fired when a client is disconnected
server.on('clientDisconnected', function(client) {
console.log('clientDisconnected : ', client.id);
});
,这是Heroku的日志报告的崩溃:

任何解决这个请???
看来,Procfile起着Heroku上有很大的作用,但问题是,Heroku的始终在索引文件中搜索默认的http/webservice –
Heroku并不认为'索引'是任何特殊的。唯一特别的是在没有Procfile的情况下假设'web'服务。在没有向Heroku指出如何开始你想要开始的过程的情况下,Heroku还会做什么来启动你的应用程序?即,如果您不告诉Heroku如何启动您的应用程序,您希望应用程序启动系统执行什么操作? – hunterloftis
