Question

我的express 4应用程序总是从端口3000开始（在此端口中忽略socketIO）当我用socket.io绑定我的快递应用程序后，我明确地听了一个不同的端口。在我设置的端口上快速+套接字启动（比方说：3030）我可以在两个端口运行我的应用程序.port 3000没有考虑socket.io和3030将其考虑在内。 localy我对此没有任何问题，但是一旦我将我的项目推送到heroku，我就得到了

EADDRINUSE地址已在使用中

这是我的配置

    {

  "private": true,

    "prestart": "npm install",
    "start": "node ./bin/www"
  },

        "express-session" : "*",
        "socket.io": ">= 0.9.6"
    }
}

我的app.js

var http = require('http').Server(app);
var io = require('socket.io').listen(http);
http.listen(3030,
  function(){
    console.log("Express server listening on port " + app.get('port'));
});


module.exports = app;

www脚本！

#!/usr/bin/env node
var debug = require('debug')('my-application');
var app = require('../app');

app.set('port', process.env.PORT || 3000);

var server = app.listen(app.get('port'), function() {
  debug('Express server listening on port ' + server.address().port);
});

我通过设置＆＃34; start＆＃34;：＆＃34; node app＆＃34;解决了这个问题。为了避免开始进入不同的端口，所以我完全得到了./bin中的wwww脚本，然后我用这个命令heroku ps:scale web=1来克服H14错误。

我的express + socket.io从两个不同的端口开始
