Heroku上的WebSocket ERR_CONNECTION_REFUSED

Question

我正在尝试使用Heroku运行节点js应用程序WebSockets.但是,我无法解决此错误(如在Chrome浏览器中看到的那样)

与'wss://myappname.herokuapp.com:27225 /'的WebSocket连接失败:连接建立错误:net :: ERR_CONNECTION_REFUSED

我使用'wss',因为Heroku在HTTPS上运行.

我的客户端代码是:

$.get("https://myappname.herokuapp.com/port",function(data){
    port = data;
    console.log(data);
    host = 'wss://myappname.herokuapp.com:' + port + '/';
    ws = new WebSocket(host);
  });

我的服务器端代码是:

var WebSocketServer = require("ws").Server
var fs = require('fs');
var express = require('express'); 
var app = express();
var http = require('http');
var port = process.env.PORT || 5000;
var request = require('request');

var server = http.createServer(app);
var serverOnPort = server.listen(port);

console.log("Server listening on port ",port);

var wss = new WebSocketServer({server: serverOnPort});
console.log("websocket server created");

任何帮助,将不胜感激.

谢谢.

所以我似乎试图用端口号覆盖它.只需使用主机就可以了wss://myappname.herokuapp.com/.
